FIELD OF THE INVENTION
• The present invention generally relates to the field of power tools, and particularly to a power tool control system for use with a variety of power tools, such as table saws, routers, and the like.
BACKGROUND OF THE INVENTION
• Power tools are used to accomplish a variety of tasks. No matter the task, the production of accurate and precise work is a high priority. Unfortunately, the precision and accuracy of work performed on these power tools is limited by human error and sub-standard equipment. Even when equipment with the latest advances, such as laser guidance technology, is employed it is often the case that the use of such technology is difficult for the equipment operator. The difficulties experienced by an operator may be due to a variety of reasons, such as inadequate instructional aids available from the manufacturer or dealer, overly complex operational requirements, or a poorly designed and organized user interface. Such difficulties have rendered many valuable advances in tool technology unpopular or obsolete due to operator dissatisfaction and frustration.
• Many power tools today have incorporated guidance mechanisms, such as laser guidance technology, into their power tool assembly. These mechanisms assist an operator in identifying and maintaining an accurate work product as the power tool executes a function upon a work piece. However, the operator is still required to establish the location of operation and this may result in imprecise and inaccurate work piece production due to imprecise measurements and settings established by the operator. Further, it is often necessary to perform different functions and then return to previous settings. Consequently, the operator is forced to establish and then re-establish settings, which may lead to further imprecision and inaccuracy in the work product produced due to operator error.
• Additionally, the use of advanced technology such as the laser guidance systems often provide user interface technology which is limited in capabilities, lacks a coherent and easily understood organizational structure for the information it gathers and provides to the operator, and makes accessing the information made available by its use difficult due to low quality display mechanisms and user interaction assemblies. Many of the difficulties experienced by operators when employing the user interface devices may primarily result from a focus on the technology and not the user. For example, the user interface may provide the ability to access numerous features but have a display mechanism that is so cluttered that it becomes burdensome to decipher the relevant information. Many times, to correct for this problem, the user interface is stripped of numerous capabilities and the user is left with insufficient resources to accomplish their tasks.
• Therefore, it would be desirable to provide a power tool control system that enables a power tool operator to establish precise and accurate measurements and settings for a power tool and provide a user friendly user interface assembly in order to ensure work product of a high quality.
SUMMARY OF THE INVENTION
• Accordingly, the present invention is a power tool control system that enables a user to operate a power tool through a graphical user interface communicatively coupled with a non-contact measurement and alignment device. The graphical user interface correlates user engageable selectors with a logically related menu of power tool setting options displayed on a display screen in a high quality and easily readable format. The non-contact measurement and alignment device uses one or more lasers to determine power tool settings and establish proper alignment based on user needs.
• In an additional aspect, the present invention includes a bevel indication assembly for use with a table saw assembly. The bevel indication assembly provides a visual indication of the beveled angle setting of a saw blade of the table saw assembly. The visual indication assists the user of the table saw assembly in establishing desired beveling of the saw blade.
• In a still further aspect, the present invention includes a router bit height indication assembly which establishes a visual indication of the bit height of a router coupled with a router table of a router table assembly. The router bit height indication assembly may provide a visual indication as a marker on an indicator. Additionally, the bit height may be provided through a display on a screen of a graphical user interface.
• The present invention further includes a level which utilizes a laser source to emit a laser beam for the establishment of measurement and alignment settings. The level may further be enabled to provide measurement and alignment settings on multiple axis of orientation. Additionally, the level may be communicatively coupled with a graphical user interface for the display of the measurement and alignment settings established by the laser beam.
• The graphical user interface is configured with multiple display screen aspect capabilities in order to increase the intuitive control of the graphical user interface and thus the power tool it is communicatively coupled with. The display screen presents the user options for display configuration, such as single-cell screen, dual-cell screen, tri-cell screen, and the like, in order to present information with increased ease of viewing to the user. Each screen configuration, described above, may be further configured to provide one or more further aspects. For instance, in a dual cell configuration, a first cell may be further defined by a first and second sub-cell and a second cell may include a first, second, and third sub-cell. It is understood that the above description is exemplary and various configurations as contemplated by those of ordinary skill in the art may be employed without departing from the scope and spirit of the present invention.
• It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention as claimed. The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate an embodiment of the invention and together with the general description, serve to explain the principles of the invention.

The twogrips128 and130 are ergonomically shaped to provide the user a secure location with which to grip thehousing102 for depressing the first andsecond buttons120 and122 and releasing the compression latches124 and126. The two grips may also be used in transporting thelaser apparatus100.
• It is further contemplated that thelaser apparatus100 may include a laser source which emits an incident laser beam from either afirst end116 or asecond end118 of thehousing102. Such a configuration may be desirable in situations where a user needs only one laser beam to produce a finished work product, such as when working on a lathe machine as shown inFIG. 10. Further, such a configuration may be desirable when employing the optical assembly of the present invention in a laser level apparatus as shown and described inFIGS. 121 through 128.
• In an alternate embodiment, the threelaser beam sources106,108, and110, may comprise modular laser source units. The modular laser source units may be capable of being removed from and inserted into thehousing102. The modular laser source units may be locked in position, once inserted into thehousing102, by use of a variety of system, such as a latch system, compression system, or the like. There may be a variety of modular laser source units disposed with laser sources of varying power. Further, the modular laser source units may include a dithering assembly enabling the laser source to provide dithering functionality. For further discussion on dithering assemblies seeFIGS. 21 through 24 below.
• Further, thelaser apparatus100 may be comprised of a single laser source. The single laser source may emit an incident laser beam through thehousing102. The single laser source may be attached at either thefirst end116 or thesecond end118 of thehousing102. Alternatively, the single laser source may be included in thecomputing system104. In a single laser source configuration optical splitters, optical reflectors, and photomultipliers may be employed in order to facilitate the functional capabilities of thelaser apparatus100. A detailed discussion of the single laser source design, including the use of optical splitters, optical reflectors, and photomultipliers, is provided inFIGS. 36 through 40.
• In the present embodiment, thecomputing system104 controls the functioning of each of the threelaser sources106 through110. A user interacts with thecomputing system104 and directs the emitting of a laser beam from each of the three laser sources. Additionally, thecomputing system104 monitors the laser beams and provides a display to the user of relevant information.
• The information provided on the display may include distance measurements, blade height measurements, blade angle, and the like. Additionally, the laser beams may provide information regarding the truing of the machine and a work piece, and the indexing of the work piece. For example, in a belt sander apparatus as will be shown and discussed inFIG. 11, the user may ensure that the angle of the sander matches the desired specifications using the laser apparatus. Further, a work piece to be presented to the sander may be verified by the laser apparatus to be in the correct position for presentation to the sander. The laser apparatus may also provide an indexing functionality by determining the leading edge of the work piece and monitoring the distance traveled by the work piece. It is contemplated that other information relevant to a variety of power tools may also be provided by the computing system to the user.

• Also shown inFIG. 2 is an alternate configuration of thehousing102 where power may be received via apower cord208 which engages asecond receptor port210. It is understood that typically only one of the above mentioned power source configurations will be employed on thelaser apparatus100 and thatFIG. 2 is only an exemplary embodiment of two possible configurations. Further, the location and configuration of the first andsecond receptor ports202 and210 may be varied as contemplated by one of ordinary skill in the art.
• Additionally, acommunication port212 is included in thehousing102 of thelaser apparatus100. Thecommunication port212 provides a communicative link to thecomputing system104, allowing the computing system to communicate with thelaser sources106 through110 disposed within thehousing102.

• FIGS. 3 and 4 show exemplary displays on thecomputing system104. Being an interactive system, thecomputing system104 includes afirst selector302, asecond selector304, and athird selector306. Thefirst selector302 and thethird selector306 allow a user to scroll through choices presented on adisplay screen308 of thecomputing system104. Thesecond button304 allows a user to select the desired application choice presented on thedisplay screen308. For example, inFIG. 3 a user may choose to turn on or turn off the lasers by using the first andthird buttons302 and306 to select the desired function and then pressing thesecond button304 to execute the function. InFIG. 4 thedisplay screen308 is providing a user with the readouts determined during the process of truing the machine. The user may accept these dimensions by selecting the “cont.” function or reject these dimensions by selecting the “reset” function. It is understood that the displays presented on thedisplay screen308 are exemplary and may not be read as exclusive. A variety of displays and interactive functionalities may be presented ondisplay screen308 without departing from the scope and spirit of the present invention.
• Various configurations of thecomputing system104 may be employed without departing from the scope and spirit of the present invention.

As described for theportable power source204 of thehousing102, theportable power source504 may be a variety of devices, such as a rechargeable battery or the like, without departing from the scope and spirit of the present invention. In an alternate configuration thecomputing system104 may receive power from apower cord508 which engages asecond receptor port510. The location and configuration of the first andsecond receptor ports502 and510 may be varied as contemplated by one of ordinary skill in the art.
• Additionally, thecomputing system104 includes a first mountingmember512 and a second mountingmember514. These two mounting members couple with thehousing102 of thelaser apparatus104. It is contemplated that a latch and release mechanism is disposed within one of the two mounting members and operably connects with the twobuttons310 and312. Further, thecomputing system104 includes acommunication adapter516 that engages with thecommunication port212, shown inFIG. 2, disposed on thehousing102.
• Referring toFIG. 6, thelaser apparatus100 is shown withcomputing system104 in vertical orientation over thecommunication port212 and the first andsecond coupling ports214 and216. The first and second mountingmembers512 and514, disposed on thecomputing system104, are positioned to engage with the first andsecond coupling ports214 and216, respectively. Thecommunication adapter516 is positioned to engage with thecommunication port212. In this preferred embodiment, a user must supply sufficient force to couple thecomputing system104 with thehousing102. As discussed above inFIG. 3, the first andsecond buttons310 and312 are operably engaged as part of a latch and release mechanism which locks thecomputing system104 in place. A latch or latches may be located on the mountingmembers512 and/or514, and as thecomputing system104 is pressed into place they may engage with the inside of thecoupling ports214 and/or216. In order to remove thecomputing system104 form thehousing102, the user will depress one or both of the first andsecond buttons310 and312, which will release the latches from the coupling ports allowing thecomputing system104 to release from thehousing102. Other systems may be employed to affix thecomputing system104 to thehousing102 without departing from the scope and spirit of the present invention.
• Thelaser apparatus100 is shown engaging a mountingassembly602. Preferably, the mountingassembly602 includes aleveling device604. The mounting assembly includes a first mountingport606, a second mountingport608, and a third mountingport610. Initially the mountingassembly602 is mounted to a power tool or other desired device by using the mounting ports. It is contemplated that the mounting ports may be a variety of configurations as contemplated by one of ordinary skill in the art. Before thelaser apparatus100 is connected a user may establish that the mountingassembly602 is in a level position by checking theleveling device604. In this way the user may ensure that thelaser apparatus100 is level once it is connected to the mountingassembly602. The mountingassembly602 further includes afirst coupling port612 and asecond coupling port614 which engage the mountingmembers112 and114 of thelaser apparatus100.
• Referring now toFIG. 7, alaser apparatus700 is shown. Thelaser apparatus700 includes ahousing member702 in communication with aremote computing system703. Thehousing member702 is disposed with afirst laser source726, asecond laser source728, and athird laser source730. Additionally, a mountingassembly704 capable of connecting with thehousing member702 and providing a communication link between thehousing member702 and theremote computing system703, is included.
• Thehousing member702 is similar to that shown and described inFIGS. 1,2, and6, except that thehousing member702 further includes acommunication adapter708 and does not include the communication port shown inFIGS. 2 and 6. Thecommunicative adapter708 communicatively couples with theremote computing system703 by engaging thecommunication adapter708 in thecommunicative coupling point706. This communicative linking allows a user of thelaser apparatus700 to control thelaser sources726 through730 through the use of theremote computing system703. Additionally, the housing member includes a first mountingmember732 and a second mountingmember734. The first mountingmember732 is disposed with a compression latch736 and is operably engaged with afirst depression button740. The second mountingmember734 is disposed with acompression latch738 and is operably engaged with asecond depression button742. The first mountingmember732 couples with afirst coupling port744 disposed on the mountingassembly704, and the second mountingmember734 couples with asecond coupling port746 disposed on the mountingassembly704. As described previously the first and second depression buttons allow the user to remove thehousing member702 from the mountingassembly704.
• Theremote computing system703 is similar to that shown and described inFIGS. 1, and3 through6 except that it couples with a remote mountingmember710. The remote mountingmember710, preferably, mounts to a stationary surface, such as a wall, and provides afirst communication port712 for coupling with acommunication adapter722 disposed on theremote computing system703. Additionally, the remote mountingmember710 includes afirst coupling port714 and asecond coupling port716 for coupling with a first mountingmember718 and second mountingmembers720 of theremote computing system703. Further, the remote mountingmember710 includes asecond communication port724 which couples with acommunication adapter707 connected to the mountingassembly704.
• The mountingassembly704 is similar to the mounting assembly shown inFIG. 6, except that the mountingassembly704 further includes acommunicative coupling port706 and acommunication adapter707. Thecommunication adapter708, disposed on thehousing member702, engages with thecommunication port706 providing a communicative link. The communicative link from thehousing member702 to theremote computing system703 is completed through the coupling of thecommunication adapter707 with thesecond communication port724 of the remote mountingmember710. The mountingassembly704 includes a first mountingport748, a second mountingport750, and a third mountingport752. These mounting ports allow the mountingassembly704 to be coupled to a variety of devices such as power tools and the like.
• A table saw system800 including thelaser apparatus100 mounted on afence804 which is connected to atable saw802, is shown inFIGS. 8 through 10C. Preferably, thelaser apparatus100 provides three laser beams. The laser beams may be used to establish three distance measurements indicated by d1, d2, and d3. These measurements are displayed to the user on thecomputing system104. Additionally, the laser beams in communication with thecomputing system104 may display a variety of information, such as circular saw blade height, circular saw blade angle, or the like. The table saw802 further includes acircular saw blade806, afirst adjustment mechanism808, and asecond adjustment mechanism810. In the present embodiment, thefirst adjustment mechanism808 enables a user of the table saw802 to adjust the angle of thecircular saw blade806 relative to the operational field of the table saw802. The operational field may be defined as that area of the table saw802 upon which a work piece may be placed and thecircular saw blade806 may perform a cut upon the work piece. In other embodiments where thelaser apparatus100 is mounted or connected to another power tool or device the operational field may include the area where the work piece is placed and a function is performed upon the work piece. Thesecond adjustment mechanism810 enables a user to adjust the height which thecircular saw blade806 extends above the surface of the operation field of the table saw802.
• Referring now toFIGS. 9 and 10A, thelaser apparatus100 coupled to atable saw802 is shown. Thelaser apparatus100 includes thehousing102 coupled with thecomputing system104. Thehousing102 is mounted to afence804 connected to the table saw802. InFIG. 9, the preferred embodiment is shown. In this embodiment thehousing102 includes afirst laser source106, asecond laser source108, and athird laser source110 each emitting a laser beam across the operational field of the table saw802, from thefence804 to thecircular saw blade806. Thelaser sources106,108, and110 may emit individual incident laser beams d1, d2, and d3, respectively, which may enable the establishment of the distance from thefence804 to acircular saw blade806. For instance, thelaser apparatus100 of this embodiment may send three readings to thecomputing system104 where an average may be computed to establish the distance reading. Alternatively, the readings from the individual laser beams may be processed by thecomputing system104 in various manners as contemplated by those of ordinary skill in the relevant art. In addition, thecomputing system104 may compute the difference between each reading and notify the user if thecircular saw blade806 is warped or bent beyond a predetermined tolerance.
• InFIG. 10A an alternative embodiment is shown. In this embodiment, thesingle laser source110 is used to measure the distance d1 from thefence804 to acircular saw blade806. It is contemplated that the single laser source may emit one or more laser beams for establishing measurement information. Thelaser source110 is communicatively coupled with thecomputing system104 which controls thelaser source110 and provides the display of the measurement information established. It is understood in both the embodiments shown inFIGS. 9 and 10A that thecomputing system104 may be remotely located from thehousing102 and thelaser sources106,108, and110 and may maintain operational control over the laser sources through remote communicative coupling as previously described. It is contemplated that thelaser source110 may be a modular apparatus enabling its removal from the housing of the laser apparatus. Modularity of thelaser source110 may enable easier replacement of damaged or inoperative laser sources and may provide for storage of thelaser source110 in a separate location.
• Referring now toFIGS. 10B and 10C, thelaser apparatus100 is shown enabled to measure the circular saw blade's height measurement. The blade height measurement is the distance between the surface of the table saw and the tallest point of thecircular saw blade806. InFIG. 10B the preferred embodiment is shown. The preferred embodiment utilizes thelaser source106,108 and110 to calculate the height of thesaw blade806. In the preferred embodiment, the three laser sources may emit individual incident laser beams h1, h2, and h3, respectively, which may enable the establishment of the height of thesaw blade806. The three readings, established by the three laser beams, are provided to thecomputing system104 where an average may be computed. This average may be used to provide an indication of the blade height. An alternative embodiment is illustrated inFIG. 10C. In this embodiment, thesingle laser source110 is used to measure the blade height. As discussed above with respect to blade distance measurement, the single laser source may emit one or more laser beams in order to establish the blade height readings. It is understood in both the embodiments shown inFIGS. 10B and 10C that thecomputing system104 may be remotely located from thehousing102 and thelaser sources106,108, and110 and may maintain operational control over the laser sources through remote communicative coupling as previously described.
• Referring now toFIGS. 11A and 11B, the table saw assembly800 is configured with thelaser apparatus100 enabled to measure the beveled angle of thecircular saw blade806. The beveled angle is the angle that thecircular saw blade806 presents at relative to the planar surface of the table802. In the preferred embodiment ofFIG. 11A, thelaser apparatus100 employs thelaser source106,108, and110, emitting individual laser beams a1, a2, and a3, respectively, to calculate the bevel angle of thesaw blade806. For instance, thelaser apparatus100 of this embodiment may send three readings to thecomputing system104 where an average may be computed. This average may be used to provide an indication of the beveled angle between thecircular saw blade806 and the planar surface of the table802. Alternatively, the readings from the individual laser beams may be processed by thecomputing system104 in various manners as contemplated by those of ordinary skill in the relevant art.
• An alternative embodiment is illustrated inFIG. 11B. In this embodiment, thesingle laser source110 is used to measure the beveled angle. As discussed above with respect to blade distance and blade height measurements, the single laser source may emit one or more laser beams in order to establish the blade angle readings. It is contemplated that the single laser source may emit one or more laser beams for establishing measurement information. Thelaser source110 is communicatively coupled with thecomputing system104 which controls thelaser source110 and provides the display of the beveled angle information established. It is understood in both the embodiments shown inFIGS. 11A and 11B that thecomputing system104 may be remotely located from thehousing102 and thelaser sources106,108, and110, and may maintain operational control over the laser sources through remote communicative coupling as previously described.
• In an alternative embodiment, the laser source configuration within thehousing102 of thelaser apparatus100, is changed. In this embodiment, thelaser source106,108, and110 are “stacked” or aligned vertically, along a mid-point of thehousing102. The individual laser beams emitted, a1, a2, and a3, provide the beveled angle readings to thecomputing system104 for display to a user. It is contemplated that the location of the “stacked” laser sources within thehousing102 may be varied without departing from the scope and spirit of the present invention.
• It is further contemplated that an alternative assembly may be used to measure and indicate the beveled angle of thesaw blade806. This alternative assembly, a bevel indication assembly1200 coupled with the table saw assembly800, fromFIGS. 8 through 10, is shown inFIGS. 12A and 12B. InFIG. 12A a first exemplary embodiment of the bevel indication assembly1200 is shown. In this embodiment alaser source1202 is coupled to anadjustment flange1204. In the present embodiment, thelaser source1202 is enabled to emit infrared laser beams. Since these laser beams are invisible to the human eye light emitting diodes are linked to the laser beam in order to provide the visual indication of the travel of the laser beam and contact with avisual marker1206. In an alternate embodiment the laser source may be enabled to emit various types of laser beams, such as an ultraviolet laser beam, or the like without departing from the scope and spirit of the present invention. It is further contemplated that the number of laser sources employed and laser beams emitted by the bevel indication assembly may vary without departing from the scope and spirit of the present invention.
• Theadjustment flange1204 rotates in a manner directly proportionate to thecircular saw blade806, which allows thelaser source1202 to accurately indicate the beveled angle when rigidly mounted to theadjustment flange1204. Thelaser source1202 in this embodiment indicates the beveled angle by emitting alaser beam1208 onto avisual marker1206 mounted to the table saw assembly200. In the preferred embodiment, thevisual marker1206 is coupled with the cabinet of the table saw assembly200. Thevisual marker1206 is equipped with a scale that may read from 0 (zero) degrees to 45 (forty-five) degrees. While it is contemplated that the scale may read from 0 degrees to 45 degrees in the present embodiment, the scale may display any range of degrees without departing from the scope and spirit of the present invention. The user may obtain a read-out from the bevel indication assembly1200 by first rotating thecircular saw blade806. In order to rotate thecircular saw blade806, the user may rotate a hand-wheel810 that is coupled to theadjustment flange1204. Theadjustment flange1204 may be coupled to thecircular saw blade806 and also thelaser source1202. Therefore, when theadjustment flange1204 rotates, thelaser source1202 may also rotate and emit thelaser beam1208 onto thevisual marker1206. Where thelaser beam1208 is emitted on thevisual marker1206 may be dependent on the angular position of theadjustment flange1204. Hence, thevisual marker1206 may be positioned on the table saw system800 so that thelaser beam1208 highlights the angle that corresponds to the actual beveled angle of thecircular saw blade806.
• It is contemplated that thevisual marker1206 may be equipped with two scales positioned side by side for beveling in either direction. Each scale may read from zero degrees to forty five degrees. It is further contemplated that, to make reading the scale more convenient, the scale may be color-coded which would allow users to associate a color with each direction of tilt. For instance, the scale for right tilt operation may be blue while the scale for left tilt operation may be green. It is still further contemplated that thevisual marker1206 may be angularly configured for mounting with the table saw system800. For example, thevisual marker1206 may form an arc. The arc may increase the precision of the readings obtained from contact of the laser beam with thevisual marker1206.
• Alternative configurations of thevisual marker1206 may be enabled, such as a triangular configuration with two separate scales disposed on two sides of the triangle. One side provides zero to forty-five degree readings for left tilt operation while the other accomplishes the same for right tilt operation. The triangular visual marker may be coupled with the table saw system800 in a manner which allows a user to adjust the triangle to show the side with the appropriate scale for the direction of tilt of the saw blade. It is also contemplated that the bevel indication assembly, including the triangular visual marker, may automatically adjust the display side of the triangular visual marker to coincide with the direction of tilt intended for the saw blade. Further alternative configurations, as contemplated by those of ordinary skill in the relevant art, may be employed without departing from the scope and spirit of the present invention.
• InFIG. 12B a second exemplary embodiment of the bevel indication assembly1200, is shown. In this embodiment, the bevel indication assembly1200 operates in the same manner as the first exemplary embodiment described in the previous paragraph. However, avisual marker1210 of the second exemplary embodiment may be located at a remote position from the table saw assembly800. In this embodiment thevisual marker1210 takes the form of a rollout mat. The mat may be positioned on the floor of the user's work area so that thelaser source1202 emits the laser beam on the angle that corresponds to the actual beveled angle, a1. By providing a means to position thevisual marker1210 on the floor, a much larger scale may be employed without restricting the users workspace. A larger scale may be easier to read from a variety of positions around the table saw assembly800 and when the table saw assembly800 is engaging larger work-pieces which may hang over the top of the table obstructing the view of the visual marker if it was coupled directly with the table saw assembly800, as described above.
• Thelaser source1202 may be a modular unit enabling its removal from theadjustment flange1204. This modularity may enable theadjustment flange1204 to be retro-fitted with various laser source assemblies. The retrofitting capability may increase the ease of use of the bevel indication assembly and the useful life span of the laser source employed. For example, one laser source, which establishes a point of light on the visual marker, may be replaced with a laser source which establishes a light line on the visual marker. The light line may increase the ease with which an operator of the table saw assembly800 may identify the beveled angle of thesaw blade806. Additionally, the laser source may be removed and stored in a location remote from the table saw assembly800. Thus, damage to the laser source may be decreased.
• Referring now toFIG. 13 a laser light indicia and readingassembly1300 is shown. In the current embodiment, the laser light indicia and readingassembly1300 comprises ahousing1302 which includes alaser source1304 in communication with acomputing system1306. Thehousing1302 is coupled with a mountingmember1308. Acommunication adapter1310 communicatively couples thecomputing system1306 with thelaser source1304 disposed within thehousing1302 through acable1311. The type of cable employed in the present embodiment is a standard serial cable. However, it is contemplated that a variety of connection mechanisms may be employed, such as wireless, infrared, or the like. Thecomputing system1306 is similar to thecomputing system104 in that it provides adisplay screen1312, afirst selector1314, asecond selector1316, and athird selector1318. Additionally, thecomputing system1306 may further include akeypad1320, as shown in the current embodiment. Thekeypad1320 may enable increased functionality of the computing system, such as increased control over the laser source.
• InFIG. 14 a laser light indicia and readingassembly1400 is shown. In the present embodiment, the laser light indicia and readingassembly1400 comprises ahousing1402 which includes alaser source1404, acomputing system1406, and a mountingassembly1408. Thehousing1402 is coupled with a mountingmember1412 for coupling with the mountingassembly1408. The mountingassembly1408 further includes acommunication adapter1410 which couples with thelaser source1404 through thehousing1402. Preferably, thecommunication adapter1410 is coupled with acable1411 which connects to the mountingassembly1408. It is understood that the configuration of thecommunication adapter1410 and type ofcable1411 employed may vary as contemplated by one of ordinary skill in the art. Through theserial cable1411 thecommunication adapter1410 is further communicatively coupled with the communication port1414.
• In the present embodiment, the communication port1414 is designed to couple with thecomputing system1406 when it is mounted to the mountingassembly1408. Further, afirst coupling port1416 and asecond coupling port1418 are disposed on the mountingassembly1408 and further engage with thecomputing system1406 when thecomputing system1406 is mounted to the mountingassembly1408. Thecomputing system1406 is similar to thecomputing system104 shown and described previously, except that thecomputing system1406 includes anindicator1420. Theindicator1420 is a light emitting diode (LED) which provides indication to the user of thesystem1400 when thecomputing system1406 is properly mounted and engaged with the mountingassembly1408. It is contemplated that thecomputing system1406 may not includeindicator1406. However, a variety of configurations may be employed forindicator1420 without departing from the scope and spirit of the present invention.
• Aleveling device1422 is disposed within mountingassembly1408. As shown and described previously inFIGS. 6 and 7 the leveling assembly ensures that the laser light indicia and readingassembly1400 is level with the device to which it is connected. A first mountingport1426 and a second mountingport1428 are employed to connect the mountingassembly1408 with the desired device. In the present embodiment the mounting ports allow for screws to be inserted and fastened to the device and the mountingassembly1408. However, it is contemplated that a variety of fastening devices and configurations may be employed.
• The mountingassembly1408 further comprises a lasersource coupling port1424. The lasersource coupling port1424 is designed to receive the mountingmember1412 which is coupled to thehousing1402 disposed with thelaser source1404. The mountingmember1412 includes a release mechanism comprised of abutton1430 disposed on thehousing1402, and alatch1432. Thebutton1430 is a depression button, operably engaged with thelatch1432, which the user may depress in order to activate thelatch1432. Thelatch1432 is a compression latch which retracts back into the mountingmember1412 when thebutton1430 is depressed. Thelatch1432 is extended away from the mountingmember1412 and engages the inner surface of the lasersource coupling point1424 to affix thehousing1402 to the mountingassembly1408.
• In the preferred embodiment, the laser source for bothFIGS. 13 and 14 is enabled as a standard single laser beam producing laser source. Alternatively, the laser source in bothFIGS. 13 and 14 may be enabled as a scanning module. A knownscanning module1500 is shown inFIGS. 15A,15B, and15C. Thescanning module1500 comprises alaser source1502 with aspherical lens1504 disposed in ahousing1503. Thehousing1503 includes anaperture1505 through which a laser beam, emitted from thelaser source1502 through thespherical lens1504, passes. The laser beam travels through acylindrical lens1506 and strikes amultifaceted polygon deflector1510. Themultifaceted polygon deflector1510 deflects the incident laser beam emitted by the laser source through thecylindrical lens1508 and out to asurface1512. Thesurface1512 is a nominal plane and the incident laser beam is provided afirst focus1514. As indicated by the arrows thescanning module1500 moves the focused laser beam along thesurface1512. The scanning module may further include two light emittingdiode assemblies1516 and1518. These assemblies emit a visible light that tracks the position of the laser beam providing an indicator for a user of the scanning module.
• The laser beam from thescanning module1500 may appear as a continuous line defined by the angle of incidence with which the laser beam strikes themultifaceted polygon deflector1510. As such, the light emitting diodes would provide the visual indication of the defined area to the user
• Thescanning module1500 receives the reflected laser beams through thecylindrical lens1508. The reflected laser beams may travel directly to the photodetector1520 or the laser beams may travel to the multifaceted polygon deflector. The laser beams which strike the multifaceted polygon deflector are deflected to a collecting mirror1522 where they are reflected to the photodetector1520. In this manner thescanning module1500 is enabled to read a surface it is scanning.
• It is contemplated that the laser source(s) employed in the laser light indicia and reading assembly and the laser apparatus may include a dithering assembly. Atypical dithering assembly1600, known in the art, is shown inFIG. 16. The ditheringassembly1600 includes alaser source1602 and amirror1604 disposed within ahousing1606 and may be employed to establish a laser beam which presents as a continuous line upon a surface. Further, it is known that dithering assemblies may comprise a pair of magnets and a pair of magnetic coils. As shown inFIG. 17 amirror1702 is coupled to abase1704 which is connected to aflexible support arm1706 that is connected to asupport member1708. Adrive coil1710 is positioned on one side of theflexible support arm1706 and afeedback coil1712 is positioned on the opposite side of theflexible support arm1706. Adrive magnet1714 is connected to thebase1704 and proximally located to thedrive coil1710 while afeedback magnet1716 is connected to thebase1704 and proximally located to thefeedback coil1712. A drive current (e.g., an oscillating drive current) is run through thedrive coil1710 and causes themirror1702 to rotate. The rotation imparted to themirror1702 causes a change in the angle of incidence of the laser beam striking the mirror, and thus imparts a change in the angle of reflection imparted to the incident laser beam. As a result, the reflected laser beam appears as a continuous line defined by the rotational range of themirror1702.
• Additionally, dithering assemblies which control the range of rotation of the mirror are known.FIG. 18 shows one such assembly where amirror1802 is connected to abase1804, which is connected to aflexible support arm1806 that is connected to asupport member1808 coupled to asurface1810. Adrive coil1812 is coupled to thesupport member1808 in proximal relation to adrive magnet1814 which is coupled with thebase1804. Afirst travel stop1816 and asecond travel stop1818 are disposed in a desired location relative to themirror1802 to provide a limited range of rotation by themirror1802.
• Alternative methods for controlling the range of rotation of the mirror in a dithering assembly may include the use of pads, as shown inFIG. 19. Themirror1902 is connected to abase1904, which is connected to aflexible support arm1906 that is connected to asupport member1908 coupled to asurface1910. Adrive coil1912 is coupled to thesupport member1908 in proximal relation to adrive magnet1914 which is connected to thebase1904. Afeedback coil1916 is coupled to thesupport member1908 in proximal relation to afeedback magnet1918, which is connected to thebase1904. Afirst pad1920 is coupled with thedrive magnet1914, and asecond pad1922 is coupled with thefeedback magnet1918. The pads, which impact with the drive and feedback coils, limit the rotation range of motion of themirror1902.
• In many dithering assemblies the effects of feedback between the drive coil/magnet and the feedback coil/magnet may have harmful effects, such as increased noise and unstable rotational amplitude production. A feedback sensor, such as a Hall sensor, may be employed to monitor electrical potential in a dithering assembly and trigger a switching of the polarity of the drive current in the drive coil at the appropriate time in relation to the position of the mirror. This switching of polarities reverses the drive force being exerted on the drive magnet and the mirror.
• Referring now toFIG. 20, atable saw system2000 including a laser light indicia and readingassembly2002, is shown. The laser light indicia and readingassembly2002 is similar to the laser light indicia and readingassembly1300 and1400 shown inFIGS. 13 and 14, and includes acomputing system2003 similar to that shown inFIGS. 13 and 14. In the current embodiment, the table saw system200 further includes a table2004, afence2006, and acircular saw blade2008. Additionally, afirst adjustment mechanism2010 and asecond adjustment mechanism2012 are included in the table saw system200 and operably engage with thecircular saw blade2008 to adjust blade angle and blade height relative to the operational field of thetable saw system2000, as described previously inFIG. 8.
• In this embodiment the laser light indicia and readingassembly2002 establishes a continuouslaser beam line2014. Thelaser beam line2014 is laid down across the operational field of thetable saw system2000 and provides a cut line for a user of the system. It is contemplated that the laser light indicia and readingassembly2002 will establish a laser beam line that tracks the position of thecircular saw blade2008. For example, if the user adjusts the angle of thecircular saw blade2008 relative to the operational field of thetable saw system2000, the laser light indicia and readingassembly2002 will monitor that change and establish a laser beam line that tracks the position of thecircular saw blade2008.
• In an alternate embodiment thelaser beam line2014 may be established using optically activated indicators that are integrated with the table2004 in positions proximal to thecircular saw blade2008. For example, the table2004 may be integrated with sensors which respond by illuminating upon being struck by light from the laser light indicia and readingassembly2002. Alternately, optically activated cables may be integrated into the table saw to provide a laser line. Regardless of the type of optically activated indicators, their positioning relative to thecircular saw blade2008 and the lines of cut that may be established through use of the adjustment mechanisms provides a user an easily ascertained path to guide the cutting of the work piece by.
• Referring now toFIG. 21, atable saw system2100 is shown. Thetable saw system2100 comprises a laser light indicia and readingassembly2102, similar to the laser light indicia and reading assembly previously described inFIGS. 13,14, and20, a table2104, afence2106, and acircular saw blade2108. The laser light indicia and readingassembly2102 is coupled to acomputing system2103, thecomputing system2103 being similar to that previously described inFIGS. 13,14, and20. Additionally, awork piece2112 is located within the operation field of thetable saw system2100 and is being guided by thefence2106 and anangular adjustment mechanism2110. Theangular adjustment mechanism2110 may position thework piece2112 in a desired angular setting and then guide thework piece2112 through thecircular saw blade2108 at the set angle. In the current embodiment the laser light indicia and reading assembly establishes a laserbeam light line2114 across thework piece2112. This laserbeam light line2114 may be used by the user as the cut line and followed throughout the cut.
• It is contemplated that the laser light indicia andreading assemblies2002 and2102 ofFIGS. 20 and 21 may include an indexing and truing functionality. An example of the truing of a work piece may include a user attempting to make a forty five degree angled cut on the work piece. The user may enter this information into the computing system in communication with the laser light indicia and reading assembly and when the work piece is set into the operational field of the table saw system, the laser light indicia and reading assembly may emit a laser beam which identifies the angle that the work piece is set at in relation to the circular saw blade. An example of the indexing of a work piece may include a user attempting to make a notch cut into a work piece that does not run the length or width of the work piece. When the work piece is set into the operational field of the table saw system, the laser light indicia and reading assembly may emit a laser beam which determines the position of the leading edge of the work piece. As the work piece is passed across the circular saw blade, the laser beam enables the laser light indicia and reading assembly to monitor the rate of travel imparted to the work piece and the overall distance of travel across the circular saw by the work piece. In this manner the laser light indicia and reading assembly may communicate to the computing system when the desired length of cut has been accomplished, and have that information passed on the user.
• The user may be notified as to the truing and indexing information through the computing system, as previously discussed. Alternatively, the laser light indicia and reading assembly may be provided with an indicator to communicate to the user that the desired specifications have been accomplished. For example, a red light emitting diode may be coupled to the housing of the laser light indicia and reading assembly for indicating to the user that the desired function has not been accomplished. A green light emitting diode, coupled to the housing of the laser light indicia and reading assembly, may indicate to the user that the desired function has been accomplished and it is time to proceed or remove the work piece from the field of operation. Other indication systems as contemplated by one of ordinary skill in the art may be employed without departing from the scope and spirit of the present invention.
• Referring now toFIGS. 22A,22B,24A, and24B, atable saw assembly2200, similar in every respect to the table sawassembly2000 and2100, includes a laser light indicia and readingassembly2202 operationally coupled with acomputing system2204. InFIGS. 22A and 22B thecomputing system2204 is shown coupled with a first exemplary docking station2208. The first exemplary docking station2208 is coupled with a mountingassembly2210 which is remotely located from the laser light indicia and readingassembly2202. Alternatively, inFIGS. 24A and 24B, thecomputing system2204 is shown disposed in a secondexemplary docking station2212 which is coupled with the laser light indicia and readingassembly2202. Either embodiment may be preferred, however, it is contemplated that alternative configurations may be employed without departing from the scope and spirit of the present invention.
• The laser light indicia and readingassembly2202 coupled with thecomputing system2204 may enable the measurement of the blade height, distance from a fence to the saw blade, and the beveled angle of the saw blade. The laser light indicia and readingassembly2202 emits alaser beam2214 from alaser source2206 which operationally engages with the circular saw blade to measure its height above the tabletop, distance from a fence, or beveled angle. The established measurement is then displayed on adisplay screen2216, of thecomputing system2204. Thecomputing system2204 may further enable the user with the ability to adjust the blade height, distance from fence, and beveled angle of the saw blade. The laser light indicia and readingassembly2202 is useful because thecomputing system2204, including thedisplay screen2216, may be located above the table sawassembly2200 as opposed to on one of its walls. This position may increase the ease of viewing from multiple positions around the table saw.
• Referring now toFIGS. 23 and 24C, atable saw assembly2300 similar in every respect to the table sawassembly2200 except that table sawassembly2300 includes a first laser light indicia and readingassembly2302 and a second laser light indicia and readingassembly2304. In the preferred embodiment, the first laser light indicia and readingassembly2302 is coupled with afence2320. It is understood that this coupling may enable movement capabilities and removal of the first laser light indicia and readingassembly2302, relative to thefence2320. Further, the second laser light indicia and readingassembly2304 is coupled with a table2324 via a mountingassembly2322. In the current embodiment, the mountingassembly2322 is coupled with the table2324 proximal to the axis of asaw blade2326. The second laser light indicia and readingassembly2304 may be adjusted relative to or removed from the mountingassembly2322. The first laser light indicia and readingassembly2302 includes afirst laser source2306 which emits afirst laser beam2310. The second laser light indicia and readingassembly2304 includes asecond laser source2308 which emits asecond laser beam2312. In the preferred embodiment, the first and second laser beams operationally contact thesaw blade2326 to establish the desired measurements, such as blade height, distance from fence, and beveled angle of thesaw blade2326.
• Mechanically coupled with the mountingassembly2322 is adocking station2318 which may engage acomputing system2314, thecomputing system2314 including adisplay2316. Thecomputing system2314 is similar to those shown and described in previousFIGS. 1 through 22. In the preferred embodiment, thecomputing system2314 is coupled with the first and second laser light indicia and reading assemblies. Thecomputing system2314 may establish the communicative coupling with the first and second laser light indicia and reading assemblies through implementation of various communication technologies, such as hardwire, blue-tooth, fiber optics, radio frequency, and the like. It is contemplated that the first and second laser light indicia and reading assemblies may be communicatively coupled to one another by similar communication technologies that establish their link with thecomputing system2314.
• It is contemplated that thecomputing system2314 may be removed from thedocking station2318 and that thedocking station2318 may be adjustably or removably coupled with the mountingassembly2322. In the alternative embodiment, shown inFIG. 24C, thedocking station2318 is coupled with the first laser light indicia and readingassembly2302. It is further contemplated that thedocking station2318 may be coupled to various other structures remote from the table sawassembly2300.
• It is understood that the laser light indicia and reading assemblies may be modular apparatus enabled to be removed from a mounting assembly or power tool as the case may be. Further, the number and configuration of laser light indicia and reading assemblies may vary without departing from the scope and spirit of the present invention. For example, three or more laser light indicia and reading assemblies may operationally engage with a saw blade of a table saw assembly. Still further, the mounting and positioning of the laser light indicia and reading assemblies, as shown inFIGS. 13 through 24 and as may be shown throughout the present application, may be optimally configured in various manners to enable the full functionality of the table saw assembly to which they may be coupled. For example, the second laser light indicia and readingassembly2304, shown inFIG. 23, may be enabled through the mountingassembly2322 to retract from the operational position shown inFIG. 23 to a secondary position which removes it from operational contact with the planar surface of the table2324.
• A flowchart illustrating functional steps which may be accomplished using the laser apparatus ofFIGS. 1 through 12 and the laser light indicia and reading assembly ofFIGS. 13 through 24, is shown inFIG. 25. Thefirst step2510 involves the setting of the machine. This involves mounting the laser apparatus to the power tool being utilized. As discussed previously, the laser apparatus may be directly mounted to a power tool or mounted to a separate mounting assembly which is connected to the power tool. Once the laser apparatus has been properly set then instep2520 the laser apparatus must be trued in order to provide accurate results. This may be accomplished by checking the leveling mechanism as described previously, if such a mounting assembly is being employed or using the laser beams to determine the correct alignment. If the laser apparatus determines that the mounting is untrue it notifies the user. Once the laser apparatus determines it is truly aligned then instep2530 the work piece is set. Once the laser apparatus determines that the work piece has been set then instep2540 it determines if the setting of the work piece is true. Once the work piece is trued the user begins operation of the power tool instep2550. When it is determined that the machining of the work piece is completed instep2560 operation of the power tool is halted.
• It is contemplated that an optically reflective material may be disposed upon a surface that is struck by the laser beam emitted from the laser apparatus or the laser light indicia and reading assembly. In this manner when the laser beams are emitted they will strike the optically reflective material and be reflected. In one embodiment the reflected laser beams may be received by an optical detector disposed within the housing of the laser apparatus or the laser light indicia and reading assembly. The optical detector may be in communication with the computing system and the computing system may process the laser beam information to determine measurements and other setting information. In alternate embodiments the reflected laser beam may be received by one or several optical detector(s) remotely located with respect to the laser apparatus or the laser light indicia and reading assembly, but in communication with the computing system. As stated above the optical detector will relay the information gathered from the laser beam to the computing system where it may be processed and displayed to a user as measurement of setting information. For example, an optically reflective material may be circumferentially disposed about a circular saw blade of a table saw. The table saw may be disposed with a fence that has a laser apparatus (as described inFIG. 1) mounted upon it. The laser apparatus may emit one or more incident laser beams which strike the optically reflective material on the circular saw blade and, if the circular saw blade is perpendicular to the incident laser beams, are reflected back towards the laser apparatus. The laser apparatus may be disposed with one or more optical detectors to receive the reflected laser beam(s) and communicate the information gathered to the computing system for processing and display to a user. The type and configuration of the optically reflective material may vary as contemplated by one of ordinary skill in the art.
• It is further contemplated that the laser apparatus or the laser light indicia and reading assembly may establish a communicative link with their respective computing systems through a communication system disposed within the device, to which the laser apparatus or the laser light indicia and reading assembly are mounted, itself. In this manner a mounting assembly as shown inFIGS. 6,7, and14 would not be necessary and the laser apparatus or the laser light indicia and reading assembly may be directly mounted to the device. Additionally, the laser apparatus or the laser light indicia and reading assembly may be enabled to accept power from the device to which they are mounted, thus, reducing the need to have a separate power source or power source connection. For example, a fence mounted to a table saw system may be disposed to connect with the laser apparatus or the laser light indicia and reading assembly. The fence may include a communication port, as shown and described on the mounting assemblies ofFIGS. 7 and 14, which couples with a communication adapter disposed on the housing of the laser apparatus or the laser light indicia and reading assembly. The fence may further include a communication adapter which may be coupled with the computing system, thereby enabling the computing system to be in communication with the laser apparatus or the laser light indicia and reading assembly. Further, the power source for the table saw system may include an outlet on the fence which may be engaged by the laser apparatus or the laser light indicia and reading assembly to provide power to either system.
• Heat build-up within the laser apparatus or the laser light indicia and reading assembly is an important concern. Overheating may result in malfunctioning of the laser source(s) within the housing and cause damage to the laser source or housing necessitating expensive repair and lost time. In one embodiment of the present invention the laser source may be a low power and low intensity laser source to minimize the heat build up with the housing. Such an embodiment is suitable for situations where the use of the laser apparatus and the laser light indicia and reading assembly is sporadic and limited. However, in a situation where the laser apparatus or the laser light indicia and reading assembly are in constant use over prolonged periods of time even a low power and intensity laser source may experience significant heat build up which may damage the system.
• To handle a situation where the heat build up is significant, the laser apparatus and the laser light indicia and reading assembly may include a cooling system. In one embodiment, the housing of either system may include vents to allow heat to escape and cooler air to be drawn into the housing to help cool the laser sources. In an alternate embodiment, the cooling system may be comprised of a fan assembly mounted within the housing to blow air through the housing and over the laser source(s). The housing may include a vent located at an end opposite the fan to allow the blown air and heat to escape. In a third embodiment a cooling system may comprise an inert coolant being run through the housing of the laser apparatus or the laser light indicia and reading assembly. The coolant system may include a tank of the inert coolant connected to the housing through tubing and then an exhaust system connected to the housing for removing and disposing of the inert coolant after it has run through the housing. It is contemplated that a coolant system may be disposed within a device to which the laser apparatus and the laser light indicia and reading assembly are connected. The inert coolant may be presented and exhausted through the mounting connection between the device and the laser apparatus or the laser light indicia and reading assembly. For example, the laser apparatus ofFIG. 1, may include connection portals in the mounting members. When the mounting members are secured to a fence, such as shown inFIGS. 8 through 10, tubing, which is connected to a tank of the inert coolant, may be connected to one of the mounting members. The inert coolant may be pumped into the housing through the mounting member and then exhausted through the other mounting member. It is contemplated that a variety of coolant systems, as may be contemplated by one of ordinary skill in the art, may be employed without departing from the scope and spirit of the present invention.
• Referring now toFIG. 26 atable saw system2600 including alaser apparatus2602, is shown. Thetable saw system2600 further includes awork surface2616, afence2618, acircular saw blade2620, and anadjustment mechanism2622. Thelaser apparatus2602 is similar to the laser apparatus ofFIG. 1 with ahousing2604 and acomputing system2614. However, thelaser apparatus2602 includes fourlaser sources2606,2608,2610, and2612 disposed within thehousing2604 and each laser source includes a dithering assembly. In the present embodiment, the laser sources establish multiple laser beam lines across the operational field of thetable saw system2600. The laser beams provide information on distance of thefence2618 from thecircular saw blade2620, the angle of thecircular saw blade2620 relative to thework surface2616, and have the ability to sense when a work piece has entered the operational field of thetable saw system2600. It is understood that thelaser apparatus2602 may gather a variety of other information as discussed inFIGS. 1 through 12, without departing from the scope and spirit of the present invention.
• Referring now toFIG. 27, atable saw system2700 including a first laser light indicia and readingassembly2702 and a second laser light indicia and readingassembly2704, is shown. Both the first and the second laser light indicia andreading assemblies2702 and2704 are coupled to acomputing system2703. The computing system controls the functionality of both laser light indicia and reading assemblies. Alternatively, each laser light indicia and reading assembly may be coupled with a separate computing system. Thetable saw system2700 further includes awork surface2706, afence2708, acircular saw blade2710, and anangle adjustment mechanism2712. The angle adjustment mechanism is similar to that discussed inFIG. 21. In the present embodiment, the first and second laser light indicia and reading assemblies are similar to the laser light indicia and reading assembly shown and described inFIG. 13, except that each of the housings is disposed with a plurality of laser sources. The plurality of laser sources may be enabled as scanning modules or include dithering assemblies to produce alaser beam grid2716 upon awork piece2714. Alternately, thelaser beam grid2716 may be established upon awork surface2706 of thetable saw system2700. Using the first and second laser light indicia and reading assemblies a user of thetable saw system2700 is enabled to establish multiple cut lines and grid points by intersecting the laser beam lines produced. The exact location of the grid points may be determined by the user and entered into the computing system which controls the laser light indicia and reading assemblies. It is contemplated that a single computing system may be enabled to control both laser light indicia and reading assemblies or that a separate and independent computing system may be used to control each laser light indicia and reading assembly. In an alternate embodiment the laser light indicia and reading assemblies may be disposed with a single laser source as described inFIG. 13.
• Referring now toFIGS. 28A,28B,29A, and29B, atable saw assembly2800 similar to the table saw assembly800 in every respect except that the table sawassembly2800 further includes a first laser light indicia and readingassembly2810 and a second laser light indicia and readingassembly2820. The first laser light indicia and readingassembly2810 is coupled with afence2860, which is coupled with a table2870. It is contemplated that the first laser light indicia and readingassembly2810 may be adjustably coupled with thefence2860 and further that the first laser light indicia and reading assembly may be removed from thefence2860. The second laser light indicia and readingassembly2820 is coupled, via a mountingassembly2880, with the table2870. It is contemplated that the mountingassembly2880 may be various assemblies, such as a riving knife assembly, blade guard assembly, and the like. Further, the second laser light indicia and readingassembly2820 may be adjustably coupled with the mountingassembly2880 or removable from the mountingassembly2880. In alternative embodiments, the second laser light indicia and readingassembly2820 may include a mounting apparatus which enables coupling, preferably adjustable and/or removable, with the table sawassembly2800.
• In the preferred embodiment, the first and second laser light indicia and readingassembly2810 and2820 are communicatively coupled with acomputing system2850 which is similar to thecomputing system104, described previously. It is understood that the first and second laser light indicia and reading assemblies may be operationally and/or communicatively coupled with various devices, such as a user interface discussed below.FIGS. 28A and 28B illustrate the multiple laser light indicia and reading assemblies measuring blade height, h1, of thesaw blade2805, whileFIGS. 29A and 29B illustrate the invention providing a reading of the beveled angle, a1, of thesaw blade2805. The first laser light indicia and readingassembly2810 employs afirst laser source2830 and the second laser light indicia and readingassembly2820 employs asecond laser source2840. In the preferred operational embodiment shown in the currentFIGS. 28A,28B,29A, and29B, the first andsecond laser sources2830 and2840 emit laser beams which establish a grid pattern of coverage upon the table2870 of the table sawassembly2800. The grid pattern established may enable the table sawassembly2800 to provide increased accuracy in the readings established. The first and second laser sources may be similar to the laser sources described previously, in that the emitted laser beams may be invisible to the human eye. Alternatively, the first and second laser sources may be enabled with assemblies, such as light emitting diode assemblies, which may visibly establish the pattern of the emitted laser beams upon the table2870.
• Arotating laser apparatus3000 including afirst housing member3002, asecond housing member3004, and acomputing system3006 is shown inFIGS. 30 through 37. Thefirst housing member3002 includes afirst laser source3014, asecond laser source3016, acommunication port3018, afirst coupling port3020, asecond coupling port3022, and agrip3024. The first housing member may include a mounting member, a latch, and a release mechanism as described previously inFIG. 1. Thesecond housing member3004 includes athird laser source3026, afourth laser source3028, and agrip3030. Thesecond housing member3004 may also include a mounting member, a latch, and a release mechanism as described previously inFIG. 1. Thecommunication port3018 provides communicative linkage to all four laser sources disposed within the first and the second housing members.
• In the current embodiment, thecomputing system3006 is coupled with thefirst housing member3002. Thecomputing system3006 is similar to thecomputing system104 described previously. The computing system includes afirst selector3032, asecond selector3034, and athird selector3036. Further, adisplay screen3038 provides an interactive medium for a user who is operating therotating laser apparatus3000. Additionally, thecomputing system3006 includes acommunication adapter3038 for coupling with thecommunication port3018 disposed on thefirst housing member3002. The computing system also includes a first mountingmember3040 and asecond mounting member3042 for engaging with the first andsecond coupling ports3020 and3022 disposed on thefirst housing member3002. Afirst button3044 and asecond button3046 operably engage with the first and second mounting members to perform a latch and release function enabling a user to secure thecomputing system3006 to thefirst housing member3002 and remove thecomputing system3006 from thefirst housing member3002. Anindicator3048 is included on thecomputing system3006 to provide a user feedback on whether thecomputing system3006 is in communication with the four laser sources.
• The twohousing members3002 and3004 are coupled by arotation mechanism3008. Therotation mechanism3008 comprises a joint3010 coupled with anangle measurement device3012. Theangle measurement device3012 includes teeth along the outer edge, away from the joint3010. The teeth of the angle measurement device are engaged by aratchet arm3050 coupled on one end with a coiledcompression spring mechanism3052 and anactivation mechanism3054 on the other end. In the present embodiment, theratchet arm3050 and the coiledcompression spring mechanism3052 are disposed on the inside of thesecond housing member3004 in a position proximal to theangle measurement device3012. Theactivation mechanism3054 extends through thesecond housing member3004 allowing the user to depress an activation push button and adjust the angle of thesecond housing member3004 relative to thefirst housing member3002.
• Preferably, joint3010 is a hinge that allows the first and second housing members to be rotated along two axes, as shown inFIGS. 31 through 35. It is understood that the joint3010 may be a variety of devices which enable such functionality as may be contemplated by one of ordinary skill in the art. Further, theangle measurement device3012 indicates to a user of therotating laser apparatus3000 the degree that thefirst housing member3002 is relative to thesecond housing member3004. The position of theangle measurement device3012 is fixed relative to thefirst housing member3002. The fixed positioning of theangle measurement device3012 may be accomplished by coupling theangle measurement device3012 to thefirst housing member3002, the joint3010, or other methods as may be contemplated by one of ordinary skill in the art. Thesecond housing member3004 is allowed to slide freely over theangle measurement device3012 as it is rotated relative to thefirst housing member3002.
• Alternatively, the rotation mechanism may be comprised of a variety of systems, such as a hydraulic system, compression system, or the like. Further, the user engagement device (i.e., the activation push button of the exemplary embodiment) may be other mechanisms as contemplated by one of ordinary skill in the art. Additionally, the rotation mechanism may be engaged directly by the user, as described above, or the rotation mechanism may be in communication with the computing system and the user may enter the desired angle and the rotation mechanism may set therotating laser apparatus3000 in the desired position.
• In the present embodiment, each of the two housing members includes two laser sources. Thefirst housing member3002 includes afirst laser source3014 and asecond laser source3016. Thesecond housing member3004 includes athird laser source3026 and afourth laser source3028. As shown inFIG. 35, thelaser sources3014,3016,3026, and3028 may form a virtual grid allowing the user to specify a particular location for the execution of a function. Alternatively, therotating laser apparatus3000 may include a fewer or greater number of laser sources disposed within each of the housing members.
• As discussed above, thecomputing system3006 is similar to the computing system described previously inFIGS. 1 through 29. In the present embodiment, thecomputing system3006 is in communication with thelaser sources3014,3016,3026, and3028, and mounts upon thefirst housing member3002. It is contemplated that the coupling of thecomputing system3006 may occur upon thesecond housing member3004. Exemplary interactive displays, readable on the computing system2405, are shown inFIGS. 31,36 and37. The interactive displays may provide the user a display of the status of the laser source(s), the angle between the first and second housing members, the type of pattern to established, and gather information from the laser beams. Further, when thecomputing system3006 is in communication with therotation mechanism3008 an interactive display on thecomputing system3006 may allow the user to enter the desired angle and have the rotation mechanism set to that angle.
• Referring now toFIG. 38, a flowchart illustrating the functional steps achieved using the interactive display of thecomputing system3006 of therotating laser apparatus3000, is shown. Instep3810 theinteractive display3008 of thecomputing system3006 asks the user to specify if an angle is required for the current assignment. The angle referred to is the angle that thefirst housing member3002 is at relative to thesecond housing member3004. If the user responds in the affirmative to this query then the user is asked to specify the angle required instep3820. After the angle has been specified or if no angle is required for the current assignment, as directed by the user inputting the information through theinteractive display3008 of thecomputing system3006, then instep3830 the laser pattern is established.
• Establishing the laser pattern occurs by the user being asked on the interactive display to specify the laser pattern required. Instep3840 the user is asked if the laser pattern is a straight laser pattern. If the user responds affirmatively, indicating that a straight laser pattern is to be established, then instep3860 the laser signal is sent to establish the straight pattern. If in step3840 a user indicates that a straight pattern is not desired then the user is asked, instep3850, if a cross pattern is to be established. If the user responds to this query by indicating that a cross pattern is not to be established then thecomputing system3006 returns to step3830 and the interactive display prompts the user that the laser pattern setting must be established. It is contemplated that thecomputing system3006, through theinteractive display3008, may allow for the user to manually enter a laser pattern to be established. If the user responds to the query ofstep3850 in the affirmative, indicating that a cross pattern is to be established, then instep3860 the laser signal is sent to establish the cross pattern.
• Referring now toFIG. 39, alaser apparatus3900 is shown. In the current embodiment, thelaser apparatus3900 comprises ahousing3902 and alaser source3904 coupled with thehousing3902. Thehousing3902 further includes a firstoptical splitter3906, a secondoptical splitter3908, and a thirdoptical splitter3910. Further, the housing includes a firstoptical reflector3912. Each of the optical splitters and the optical reflector is disposed within thehousing3902 in proximal location to afirst emitter3914, asecond emitter3916, athird emitter3918, and afourth emitter3920, respectively. The optical splitters function to split an incident laser beam received into two or more refracted laser beams. For example, inFIG. 39, anincident laser beam3922 from thelaser source3904 strikes the firstoptical splitter3906 whereupon the incident laser beam is divided into afirst laser beam3924 and asecond laser beam3926. Thefirst laser beam3924 is directed to the first emitter3314 where it is emitted from the housing across an operational field. The operational field may be a variety of work area, such as those found on a table saw, drill press, belt sander, lathe, or the like. The second refractedlaser beam3926 is directed towards the secondoptical splitter3908. In effect, thesecond laser beam3926 is the incident laser beam for the secondoptical splitter3908 whereupon striking the second optical splitter the second refracted laser beam is divided into athird laser beam3928 and afourth laser beam3930. Thethird laser beam3928 is directed to thesecond emitter3916 where it is emitted form the housing across the operational field. Thefourth laser beam3930 becomes the incident laser beam for the thirdoptical splitter3910. The thirdoptical splitter3910 divides the laser beam into afifth laser beam3932 and asixth laser beam3934. Thefifth laser beam3932 is directed to thethird emitter3918 where it is emitted from the housing across the operational field. Thesixth laser beam3934 becomes the incident laser beam for the firstoptical reflector3912. The firstoptical reflector3912 directs the laser beam to thefourth emitter3920 where it is emitted from the housing across the operational field.
• A single laser source may reduce the power consumption of the current invention and provide a more effective way to deal with heat build up, which is inherent within a laser beam generating source. In an alternate embodiment the laser source may be a modular laser source capable of being inserted and removed from the housing of the laser apparatus. This may increase operational safety and provide an easier method of caring for the laser source by being able to remove it and store it in a separate location. Additionally, a variety of laser sources may be enabled to couple with the housing of the laser apparatus of the current invention. Thus, the user of the laser apparatus with a modular laser source has the capability of inserting the appropriate laser source for the job to be accomplished. For example, the user may need a simple laser source for one job and then require a laser source with a dithering assembly for another job. Additionally, the user may require a smaller output laser source in one situation and a larger output laser source in another. The needed functionality required by the user may be easily enabled with multiple modular laser sources with differing functional capabilities.
• Referring now toFIG. 40, alaser apparatus4000 is shown. In the present embodiment thelaser apparatus4000 comprises ahousing4002 coupled with acomputing system4004. Preferably, thecomputing system4004 is similar to the computing systems described previously, except that in the present embodiment thecomputing system4004 includes alaser source4006. The housing includes a firstoptical splitter4008, a firstoptical reflector4010, a secondoptical splitter4012, a thirdoptical splitter4014, and a secondoptical reflector4016. The housing further includes afirst emitter4018, a second emitter4020, athird emitter4022, and afourth emitter4024.
• Thelaser source4006 emits an incident laser beam into thehousing4002 which is then split by a firstoptical splitter4008 into afirst laser beam4026 and asecond laser beam4028. Thefirst laser beam4026 is directed to the firstoptical reflector4010 where it is reflected through the firstoptical emitter4018 and emitted across an operational field. Thesecond laser beam4028 is directed to the secondoptical splitter4008 which divides the second laser beam into a third laser beam4030 and a fourth laser beam4032. The third laser beam4030 is directed through the second emitter4020 across the operational field and the fourth laser beam4032 becomes the incident laser beam for the thirdoptical splitter4012. The thirdoptical splitter4010 divides the fourth laser beam4032 into a fifth laser beam4034 and a sixth laser beam4036. The fifth laser beam4034 is directed through thethird emitter4022 across the operation field and the sixth laser beam4036 becomes the incident laser beam for the secondoptical reflector4014. Upon striking the secondoptical reflector4014, the sixth laser beam4036 is reflected through the fourthoptical emitter4024 and emitted across the operational field.
• In an additional embodiment, the laser apparatus may include an optical splitter control mechanism. This mechanism may allow a user to determine the number of laser beams emitted from the housing of the laser apparatus. This may be beneficial when the laser apparatus is being used in situations where the size of the work surface and other components are constantly changing. For example, on a table saw all four emitters may need to be engaged to cover the work surface presented. However, a drill press may have a much smaller working surface and using more than two emitters may not be beneficial to gathering the needed information as they may be outside the scope of the work surface available.
• Referring now toFIG. 41, arotation laser apparatus4100 including asingle laser source4102 is shown. Thesingle laser source4102 emits anincident laser beam4104 which is split by a firstoptical splitter4106 and a secondoptical splitter4108. The laser beam is also reflected by a firstoptical reflector4110 and a secondoptical reflector4112. The optical splitters and reflectors function in the same manner as described previously inFIGS. 39 and 40. In the present embodiment thesingle laser source4102 is located within the joint4114 connecting afirst housing member4116 to asecond housing member4118. Power may be provided through a portable power source or a power cord as described in previous figures.
• Arotation laser apparatus4200 including afirst laser source4202 and asecond laser source4204 is shown inFIG. 39. In the present embodiment a first housing member3606 is disposed on one end with the first laser source3602 and connected at the opposite end, through joint3608, to a second housing member3610. The second housing member3610 is disposed on the opposite end of its connection to the joint3608 with the second laser source3604. The first housing member3606 further includes a first optical splitter3612 and a first optical reflector3614. The second housing member3610 further includes a secondoptical splitter4216 and a secondoptical reflector4218. The operation of the splitters and reflectors is similar to that previously described inFIGS. 39 and 40.
• In bothFIGS. 41 and 42 the number and configuration of optical splitters and reflectors may vary as contemplated by one of ordinary skill in the art. It is understood that the laser sources shown in the present embodiments are exemplary and may not be read as limiting or exclusive. As discussed inFIGS. 39 and 40 the laser apparati ofFIGS. 41 and 42 may includes photo multipliers of various configurations in order to provide additional functionality to the laser apparatus. Alternatively, the laser sources provided inFIGS. 41 and 42 may be modular. The laser sources may be removed from the joint or the housing members and replaced with alternate laser sources.
• Referring now toFIG. 43, alaser apparatus4300 is shown. Thelaser apparatus4300 comprises ahousing4302 disposed with alaser source4304. The housing is further disposed with a first optical splitter4306, a secondoptical splitter4308, a thirdoptical splitter4310, and anoptical reflector4312. The functionality of the optical splitters and the optical reflector is similar to that described inFIGS. 39 through 42. Additionally, the housing includes afirst emitter4314, asecond emitter4316, athird emitter4318 and afourth emitter4320.
• In the present embodiment, a plurality of lightsignal enhancing instruments4322,4324,4326, and4328. These light signal enhancing instruments may be photomultipliers comprising a variety of designs, such as photomultiplier end-on tubes, side-on photomultipliers, or the like. The photomultipliers may accept an incident laser beam and intensify the light signal by increasing the number of electrons in order to maintain sufficient light signal strength as the laser beam is being passed down from one optical splitter to the next. Further, the light signal enhancing instruments may be positioned in front of the emitters in order to provide optimum light signal output.
• Alternatively, the light signal enhancing instruments may include a secondary laser source, such that the incident laser beam received has its signal strength increased. For example, a low power laser source may be included within the light signal enhancing instrument which contributes a second light signal to the existing laser beam in order to make up for a loss of light signal intensity. Such a system of multiple light signal enhancing instruments may decrease production costs by substituting low power laser sources for separate and independent laser sources located throughout the laser apparatus. It is understood that the configuration and numbers of light signal enhancing instruments may vary as contemplated by one of ordinary skill in the art.
• Referring now toFIGS. 44,45, and46, alaser apparatus4400 is shown. In the current embodiment, thelaser apparatus4400 comprises ahousing4402 including aleveling mechanism4404 and awireless receiver4406. Thehousing4402 further includes acommunication port4407, anattachment adapter4408, and anattachment receiver4410. Additionally, thehousing4402 includes afirst laser source4412, asecond laser source4414, athird laser source4416, and afourth laser source4418. Theleveling mechanism4404 enables a user to determine the level characteristics of thelaser apparatus4400 in any location. Previous embodiments of the laser apparatus showed the leveling mechanism within the mounting assembly. By placing the leveling mechanism within thehousing4402, the user may establish accurate placements in locations such as on a wall for use in mounting a drop ceiling, as shown inFIG. 46.
• Thelaser sources4412 through4418 are similar to the laser sources shown and described previously. It is contemplated that a laser source may be located to emit a laser beam from either end of thehousing4402. For example, a laser source may be positioned within theattachment adapter4408. By placing the laser source at either end of the housing thelaser apparatus4400 may be enabled to determine the level characteristics of objects located along a flat surface to which thelaser apparatus4400 is mounted, such as a picture on a wall or the like.
• Thewireless receiver4406 enables communication between thelaser apparatus4400 and acomputing device4502, shown inFIG. 45. In alternate embodiments the computing system may be communicatively coupled to the laser apparatus using a variety of systems, such as serial cable, Bluetooth, Infrared, or the like. The wireless communication system allows a user to mount thelaser apparatus4400 in a remote location, such as that shown inFIG. 46, and receive information on thecomputing system4502. For example, shown inFIG. 46, thelaser apparatus4400 is mounted to a wall to provide leveling information for a drop ceiling. Afirst laser beam4602 and asecond laser beam4604 are shown striking asupport rail4606 for the drop ceiling. In this situation the laser apparatus may communicate to the computing system that thesupport rail4606 is not level at the two identified points. Athird laser beam4608 and afourth laser beam4610 may provide no such indication that thesupport rail4606 is out of level. Thus, a user is informed not only of the misalignment but also where along thesupport rail4606 the misalignment is occurring.
• Theattachment adapter4408 and theattachment receiver4410 enable linking of one laser apparatus to another. As shown inFIG. 45, a plurality oflaser apparatus4400 may be connected. In this embodiment, the multiple laser apparatus are in communication with thecomputing system4502. It is contemplated that the attachment adapter and attachment receiver provide a communicative link between each of thelaser apparatus4400 allowing a single computing system to control all connected laser apparatus. Alternately, each laser apparatus may receive thewireless signal4504 being sent out by thecomputing system4502.
• It is understood that theleveling mechanism4404 may be disposed within any of the previous embodiments of the laser apparatus, shown inFIG. 1 or30. It is further understood that thelaser apparatus4400 may include mounting members and latch and release mechanisms, such as those previously shown and described inFIG. 1. Additionally, a mounting assembly for connecting thelaser apparatus4400 to a wall or other vertical surface is contemplated. Thecommunication port4407 enables a computing system to communicate with thelaser sources4412 through4418. Thehousing4402 of thelaser apparatus4400 may be disposed with both thewireless receiver4406 and thecommunication port4407 or one or the other.
• Smooth and easy operational control over a complex technological system, such as a laser guidance, measurement, and alignment system, may be critical to the success of any device. In the power tool field, this is even more critical as a user of power tools employing complex technology is often faced with a chaotic and dangerous working environment filled with loud noises, many moving parts, dust and debris which hamper visual capabilities, and a variety of different operations which require their attention. Therefore, the control device that the user employs to control the power tool must be simple and yet effectively provide the capability to control numerous complex tasks. In the field of power tools, the control device may be referred to as the user interface. The user interface of the present invention is designed to better serve the user by focusing on providing complex technology in an easy to understand or intuitive format.
• Many times when complex technologies are incorporated into existing devices, such as laser systems with power tools, the focus is on the technology and the user is forced to comprehend a bewildering array of new standards and display terminology. With the present invention the technology serves the user by joining the complexity of the laser system with a user interface that provides simple to follow and easy to understand textual and/or graphical representations. Out-of-the-box implies a level of user friendliness with the idea being that any user may take the present invention and by simply turning it on, start using it with ease. For example, when a user interface in accordance with an exemplary embodiment of the present invention is first turned on it may provide a calibration of the current settings of a power tool environment without being prompted by the user. From the calibration the user interface logically organizes and communicates the information to the user. Additionally, the user interface may present the user with operational choices logically related through easy to identify monikers providing a smooth flow to the user's navigation through the various user interface applications. Another example of the ease of use of the current user interface may involve the use of circular saws. All circular saw blades establish a kerf during their cut. A kerf is the area of material removed by the blade during the cut. While the kerf may be a minimal value it is not always an insignificant value and a user may wish to have the ability to account for the kerf of the cut when establishing settings. The user interface of the present invention may provide an operator the capability of determining the kerf for the circular saw blade through a user selectable menu of choices with pre-programmed kerf information. In the alternative, the user interface may establish the kerf of the circular saw blade being used without operator input and adjust all settings made to account for the kerf. Another embodiment of the present invention may be the user interface being able to determine the kerf of the circular saw blade being used through identification of a marker on the blade, such as a bar code imprinted on the blade. It is understood that adaptation of the user interface for use with other types of power tools may also include the ability to account for the amount of material removed by the power tool when establishing settings for the power tool.
• The correlation by the user interface of the selectors engaged by the user with the information the user sees on the display screen is an example of focusing on the user. This simple and effective design gives the user both qualitative and quantitative feedback on the various types of information the user may wish to see or adjust. The selectors may be buttons located on any surface of the user interface which provides for the appropriate correlation of the buttons with the icons on the display screen. Providing a display screen using liquid crystal display (LCD) technology is another example of focusing on the user. The LCD provides a visual field which has been proven to effectively reduce visual identification stress for a user. The color scheme and font types for the textual and graphical representations are designed to increase ease of use, even in the often dynamic working environments within which the user interface may be employed. Providing a backlit display screen also highlights the focus of the present invention, which is on the user.
• Powering the user interface of the present invention may occur through the use of batteries which are received in a battery cavity within the user interface. The user interface allows for the use of standard types of batteries for easy replacement and cost reduction. It is understood that the user interface may employ a variety of power sources, such as AC power through the use of a standard AC cord or fuel cells. Regardless of the power source used, the user interface provides a clear display to the user of the status of the power source. This may be helpful to avoid unnecessary delays caused by power failures which may have been avoided had the operator of the user interface known the status of the remaining power supply.
• The user interface of the present invention may provide a computing system capable of executing applications which are visualized for the operator on a display. Thus, the user interface is enabled to receive updates to its current applications inventory or replacement of applications should the need arise. For example, the user interface may execute a specific range of applications for the operation of a power tool such as a table saw, or the like. However, the operator may wish to retro-fit the user interface on a belt sander. The belt sander will have different operating requirements and capabilities than a table saw and therefore the user interface may need to download an application set directed for the operation of a belt sander. Accomplishing this updating or replacing of applications may occur using a variety of different technologies. For instance, the user interface of the present invention may include a docking station which, when the user interface is docked, allows for a communicative link to be established between the user interface and a peripheral computing system. Thus, information may be downloaded to the user interface from the peripheral computing system and the user interface may upload information to the peripheral computing system. The user interface may be disposed with communications ports, such as a serial cable port, infrared port, RF port, Bluetooth port, and the like, which allow it to network with peripheral computing systems.
• Through a user interface of the present invention, an operator of a power tool, such as a table saw, may establish the settings and measurements to be used with the power tool. For example, a user of the table saw may set a desired fence to blade distance, blade height, blade angle, etc., through the user interface. When the feedback from thelaser apparatus100 indicates that the desired orientation has been reached it may provide an indication to the user, through the user interface. Indicators may include visual and audio feedback, and the like. For example, a sound feedback mechanism provided by a user interface of the present invention may present an audible signal to a user when a tool is in the selected position (e.g., when a saw blade has a desired height or angle, when a fence is in a desired distance from a saw blade, or the like). In a variation of this mechanism, the sound feedback mechanism may emit via a microphone/speaker a series of beeps or other noises to a user that guide the user in the positioning of the tool. For example, the beeps may become louder, more frequent, and/or change in pitch the closer the tool is to the desired position. Alternatively, a user interface of the present invention may provide visual feedback mechanism (not shown) which presents a visual signal on its display. For example, this visual signal may be as simple as a light or other symbol being displayed on the display of the user interface when the tool is in the desired position. In a variation of the visual feedback mechanism, arrows or other visual direction-guiding signals may be presented on the display to guide the user to the desired position of the tool.
• A user interface in accordance with the present invention may be coupled with a laser measurement and alignment device. The laser measurement and alignment device may comprise thelaser apparatus100 andcomputing system104 shown and described inFIGS. 1 through 46 or may comprise a variety of systems as contemplated by one of ordinary skill in the art. The coupling may enable the user interface to be selectively or permanently detached from the laser measurement and alignment device. The user interface may communicate with the laser measurement and alignment device via a physical communication line (such as a cable) or via a wireless signal. It is contemplated that the user interface may couple directly with thelaser apparatus100 or may communicatively couple with thecomputing system104 which in turn is coupled with thelaser apparatus100. The communicative coupling may allow the user interface to operatively control thelaser apparatus100 from a remote location. Thus, the user interface may control a power tool, upon which the laser measurement and alignment device is coupled, from a remote location.
• In an exemplary embodiment, the interface may include its own power supply so that the interface may transmit signals to the laser measurement and alignment device when detached therefrom. Alternatively, the interface and the laser measurement and alignment device may share a single power source. The power source may be batteries, fuel cells, or the like. In a further embodiment of the present invention, the user interface may include laser sources, similar to those shown and described for thecomputing system104. Moreover, the software loaded onto a user interface may be updated through a diskette, a DVD, a CD, the Internet, a network, or the like.
• According to an exemplary embodiment of the present invention, a user interface may include a display which showsexemplary screens4700 through5300 shown inFIG. 47 through 53. As shown inFIG. 47 through 53, each screen includes four tabs: a home tab (labeled with a “home” icon), a settings tab (labeled with a “gear” icon), a calibration tab (labeled with a “reversed triangle” icon), and a save tab (labeled with a “diskette” icon). A user may toggle among different screens by touching an appropriate tab.
• As shown inFIG. 47, anexemplary home screen4700 is shown. Thescreen4700 shows a distance icon and its corresponding value (“121/4″”), an angle icon and its corresponding value (6.1.degree.), and a height icon and its corresponding value (“11/4″”). From thescreen4700 shown inFIG. 47, when the settings tab is touched, thescreen4700 may be replaced with asettings screen4800 shown inFIG. 48. Thescreen4800 may show information such as the battery status of the user interface or the laser measurement and alignment device, and the like. From thescreen4800 shown inFIG. 48, when the calibration tab is touched, thescreen4800 may be replaced with acalibration screen4900 shown inFIG. 49. Through thecalibration screen4900, a user may calibrate the laser measurement and alignment device. From thescreen4900 shown inFIG. 49, when the save tab is touched, thescreen4900 may be replaced with asave screen5000 shown inFIG. 50, through which a user may save a height.FIG. 51 shows an additionalexemplary save screen5100, through which a user may save a distance.FIG. 52 shows a furtherexemplary save screen5200, through which a user may save an angle.FIG. 53 shows a still furtherexemplary save screen5300, which shows various other exemplary icons (e.g., a speak icon for adjusting the volume of the speaker, and the like).
• It is understood that the foregoing-described screens shown inFIGS. 47 through 53 are intended as exemplary only and not as a limitation to the present invention. Those of ordinary skill in the art will appreciate that various combinations and arrangements may be employed without departing from the scope and spirit of the present invention.
• A user interface coupled with a laser measurement and alignment device in accordance with an exemplary embodiment of the present invention may operate according to a scheme5400 shown inFIGS. 54A and 54B. As shown inFIGS. 54A and 54B, when a laser measurement and alignment device and a user interface are not attached to a power tool (e.g., a table saw, belt sander, lathe, drill press, nailer, router table, and the like), the laser measurement and alignment device and the user interface may be used to do other measurements unrelated to the power tool or may be recharged. Additionally, the software loaded onto the user interface may be updated. For instance, the user interface may include a disk drive for loading software applications and saving information onto a removable memory media. Alternatively, the user interface may include a drive for a DVD, a CD-ROM, flash memory devices, and the like, for receiving software updates. When a laser measurement and alignment device and a user interface are attached to a power tool (e.g., a table saw, or the like), the laser measurement and alignment device and the user interface may be used to perform measurements on the power tool. Additionally, the laser measurement and alignment device may be automatically calibrated through the user interface.
• In one embodiment of the present invention, a user interface may include four operational modes: distance, angle, height, and settings, as shown inFIGS. 54A and 54B.
• In a distance mode, a user may set a desired distance, e.g., a distance between a saw blade and fence of a table saw through the user interface. In the exemplary embodiment shown inFIGS. 54A and 54B, the user interface in a distance mode may include five options: (1) return to home state; (2) fine adjustment; (3) recall dimension (i.e., recall a previous saved distance); (4) save dimension (i.e., save the current distance); and (5) back one level. Under the fine adjustment option, the user interface may include three options: (1) zero dimension, either absolute or relative; (2) units (fraction, decimal, or metric); and (3) add offset distance.
• In an angle mode, a user may set a desired angle, e.g., an angle between a saw blade and a line perpendicular to a table surface of a table saw through the user interface. As shown inFIGS. 54A and 54B, the user interface in an angle mode may include five options: (1) return to home state; (2) fine adjustment; (3) recall angle (i.e., recall a previous saved angle); (4) save dimension (i.e., save the current angle); and (5) back one level. Under the fine adjustment option, the user interface may include two options: (a) zero dimension (either absolute or relative); and (b) compute an angle (a result based on miter and bevel).
• In a height mode, a user may set a desired height, e.g., a height of a saw blade over a table surface of a table saw through the user interface. As shown inFIGS. 54A and 54B, the user interface in a height mode may include five options: (1) return to home state (the interface directly returns to a home screen when this option is chosen); (2) fine adjustment; (3) recall dimension (i.e., recall a previous saved height); (4) save dimension (i.e., save the current height); and (5) back one level (the interface goes back one level when this option is chosen). Under the fine adjustment option, the user interface may include two options: (a) zero height (either absolute or relative); and (b) units (fraction, decimal, or metric).
• In a settings mode, a user may set desired settings for the user interface. As shown inFIGS. 54A and 54B, the user interface in a settings mode may include five options: (1) return to home state; (2) global units; (3) calibration; (4) system; and (5) back one level. Under the global units option, the user interface may include three options: (a) fraction; (b) decimal; and (c) metric. The default unit may be fraction. Under the fraction unit, a user may choose a resolution such as 1/128, 1/64, 1/32, or the like. Under the decimal unit, a user may choose a resolution such as 0.0, 0.00, 0.000, or the like. Under the calibration option, the user interface may include three options: (a) measurements (distance, angle or height); (b) fence side (either left or right); (c) fence orientation (either horizontal or vertical). Under the system option, the user interface may include three options: (a) sound (either on or off); (b) display (to adjust brightness and contrast of the display); and (c) laSerial Under the laser option, the user interface may include three options: (i) on (laser is on for 10 seconds, 20 seconds, 30 seconds, or the like); (ii) off (laser is off); and (iii) sleep mode (laser falls asleep after laser is on for 10 seconds, 20 seconds, 30 seconds, or the like. Additionally, under the system option, a user may update the software loaded onto the user interface.
• It is understood that the number of modes and options available under each mode and the variety of operations which may be performed by the user interface may vary without departing from the scope and spirit of the present invention. For instance, other options under the save dimension option, found under the distance mode, angle mode, and height mode, may include: (1) save to diskette, (2) save to CDR, and (3) save to flash media. Additionally, each screen in a particular mode may include an icon for accessing the other modes directly. For example, under the distance mode each screen presented to the user of the user interface may include an icon for the angle mode, height mode, and setting mode. By selecting the individual icon the user may be taken directly to the selected mode and presented with the series of options available under that mode.
• FIG. 55 shows anexemplary user interface5800 with different exemplary screens which may execute the scheme5400 shown inFIGS. 54A and 54B.FIG. 56 shows theuser interface5800 with an exemplary calibration screen, andFIG. 57 shows theuser interface5800 with an additional exemplary calibration screen. Theuser interface5800 will be described in detail along withFIG. 58.
• Referring now toFIG. 58, theexemplary user interface5800 will be described in more detail. Theinterface5800 includes adisplay5802 and a plurality of user input controls, which are generally indicated at5804. Thedisplay5802 may be LCD (liquid crystal display), a pixel-based display, or the like. As shown, thecontrols5804 include a plurality of push (or enter)buttons5806,5808,5810,5812 and5814. Thebuttons5806 through5814 enable a user to toggle between the screens and modes displayable on thedisplay5802, and to select and input values for any of the available options, as discussed in more detail subsequently. InFIG. 58, thebuttons5806 through5814 are positioned at the bottom of theinterface5800 and correlate with an option on thedisplay5802 available for selection by the user. However, thebuttons5806 through5814 may be positioned anywhere on theinterface5800 as may be contemplated by a person of ordinary skill in the art. In the exemplary embodiment shown, thebuttons5806 through5814 are all enter buttons. However, it is within the scope of the present invention that other configurations and numbers of buttons may be used. Similarly, other forms of user input controls may be used, such as slides, track balls, switches, and pointing devices. Of course, although the described user interface is relatively large and complex, it is also possible to provide a much smaller user interface with less information displayed at a time.
• FIG. 58 illustrates a default, or home,screen5816 of thedisplay5802. This is the screen that is most often displayed to a user, and to which the controller defaults after user inputs are completed on any of the subsequently described screens. As shown, the display5802 (and hence each screen of thedisplay5802, including the home screen5816) includes abattery region5818, adeveloper region5820, a current-screen region5822, asettings region5824 and an available-option region5826.
• Thebattery region5818 provides a user with information about the status of batteries used to provide power to the laser measurement and alignment device and theuser interface5800. This feature is useful to allow a user to monitor the status of the battery during use. In particular, a user may want to check the remaining battery capacity before starting a project that may require more battery reserve than currently available. As shown, thebattery region5818 includes asmall battery icon5828 and alarge battery icon5830. Each of theicons5828 and5830 has incremental bar-graph-like readings representing the theoretical amount of battery life remaining. It is understood other textual or symbolic representations may be used without departing from the scope and spirit of the present invention. Theicon5828 may be used to indicate the status of the battery used to provide power to one of theuser interface5800 and the laser measurement and alignment device (e.g. the user interface5800), and theicon5830 may be used to indicate the status of the battery used to provide power to the other of theuser interface5800 and the laser measurement and alignment device (e.g., the laser measurement and alignment device). Alternatively, thebattery region5818 may include a single icon of a battery with incremental bar-graph-like readings representing the theoretical amount of battery life remaining when the battery is used to provide power to both the laser measurement and alignment device and theuser interface5800. It is understood that thebattery region5818 may be positioned on thedisplay5802 as may be contemplated by a person of ordinary skill in the art.
• Thedeveloper region5820 may provide various information such as identifying the developer of theuser interface5800. Alternatively, thedeveloper region5820 may be not included in thedisplay5802 at all in order to save space. In another embodiment thedeveloper region5820 may provide an indication of ownership of the individual user interface. For example, a user may place a specific logo in this region to identify the user interface as their own. It is understood that the location and configuration of the developer region on thedisplay5802 may vary. For instance, the developer region may be sub-divided into multiple sub-regions. Further, each user interface may be enabled with a security feature which allows the individual unit to be protected from unauthorized use by another. For example, the security feature may include a user being able to enter a password into the user interface which is required before operation of the user interface will be allowed. It is contemplated that other security features may be incorporated into the present invention as contemplated by one of ordinary skill in the art.
• The current-screen region5822 is used to show the screen status of theuser interface5800 and will be described in more detail subsequently. As shown inFIG. 58, the current-screen region5822 of thehome screen5816 is empty. Alternatively, the current-screen region5822 of thehome screen5816 may include graphic and/or textual representations indicating that the present screen is the home screen.
• Thesettings region5824 displays information to the user about the current setup of programmed and user-selected modes for the tool (e.g., a table saw, or the like). As shown inFIG. 58, theregion5824 includes at least onemode icon5832 and its (their) corresponding value(s)5834. For example, as shown inFIG. 58, three operational mode icons are shown on thehome screen5816, each of which has at least one value. The three illustrated mode icons aredistance5836,angle5840, andheight5844, each of which having a correspondingvalue5838,5842, and5846, respectively, and may trigger the display of one or more additional screens, as described in more detail subsequently. It should be understood that the textual names for the modes may be used in place of or in conjunction with the mode icons. Additionally, althoughFIG. 58 shows a mode icon positioned below its corresponding value, other arrangements may be utilized as may be contemplated by a person of ordinary skill in the art. For example, a mode icon (and/or textual name) may be positioned to the left, to the right, or above its corresponding value without departing from the scope and spirit of the present invention.
• Preferably, thedistance value5838, theangle value5842, and theheight value5846 in thesettings region5824 are all displayed in a clear fashion to a user so that the user is not confused by the numbers inside these values. Different fonts, sizes, and/or color may be used to distinguish different numbers. It is understood that visual clarity and the ease with which an operator of the user interface can view the information presented on thedisplay5802 may implicitly establish a preferable range of fonts, sizes, and colors used by the user interface. Further, the amount of information to be presented on each screen of thedisplay5802 may determine/establish a range of fonts, sizes, and colors to be used. This is another example of the user focus of the present invention, making complex technology available in a simple and effective manner. If a number is presented as an integer plus a fraction, the integer may be preferably presented in a larger font than a numerator and a denominator of the fraction. For example, as shown inFIG. 58, thedistance value5838 is “51/4″” in which the number “51/4” is an integer “5” plus a fraction “¼”, and the height value is “2 1/16” in which the number “2 1/16” is an integer “2” plus a fraction “ 1/16”. The integers “5” and “2” are presented in a larger font than the numerator “1” and the denominators “4” and “6” so that a user is not confused by the numbers in thevalues5838 and5846. Moreover, if a value includes a decimal expansion of a number, the decimal digit(s) before the decimal point may be preferably presented in a larger font than the decimal digit(s) after the decimal point. For example, as shown inFIG. 58, theangle value5842 includes a decimal expansion “5..sup.1”. The decimal digit “5” before the decimal point is presented in a larger font than the decimal point “1” after the decimal point so that a user is not confused by the numbers in thevalue5842. It is understood that other methods as may be contemplated by a person of ordinary skill in the art may be used to distinguish numbers in avalue5834 so that a user is not confused by those numbers.
• For each screen of thedisplay5802 of theinterface5800, the available-option region5826 has a plurality of tabs used to show available options a user may have from the current screen. Each of the tabs may use an icon, textual, and/or graphic representation to indicate an option available from the current screen. Each of the tabs is correlated to a user input control (e.g., a button, touch pad, and the like). To choose an option representing a tab, a corresponding user input control may be operated on (e.g., a corresponding button is pushed, or the like). In a preferred embodiment, as shown inFIG. 58, each tab is correlated to a button directly below. This correlation of location, establishing a user input control in direct physical proximity to the tab, provides an ease of use of the present invention generally not seen in the art.
• On thehome screen5816 shown inFIG. 58, the available-option region5826 has fivetabs5848,5850,5852,5854, and5856, each of them is correlated to a button directly below. It is noted that although each tab on thehome screen5816 as shown inFIG. 58 uses an icon to represent an available option, any of the tabs may alternatively use a textual and/or graphic representation to indicate an available option without departing from the scope and spirit of the present invention.
• As shown inFIG. 58, thetab5848 is labeled with a “home” icon filled with color different from the background, indicating the current screen is thehome screen5816. Moreover, thetab5848 may be marked differently from the four other tabs (e.g., thetab5848 inFIG. 58 has no horizontal line above the “home” icon) to indicate that the current screen is thehome screen5816. Thetab5848 is correlated to thebutton5806. When thebutton5806 is pushed, thehome screen5816 remains (since the current screen is the home screen).
• As shown inFIG. 58, thetab5850 has a “distance” icon representing an option of setting the distance between the saw blade and the fence and is correlated to thebutton5808. From thehome screen5816 shown inFIG. 58, when thebutton5808 is pushed, thehome screen5816 is replaced with adistance screen6300 shown inFIG. 63, and theuser interface5800 enters into a distance mode. Thedistance screen6300 may then be replaced with other exemplary screens in a distance mode shown inFIG. 59 andFIGS. 64 through 74 when an appropriate button (or buttons) is pushed.
• As shown inFIG. 58, thetab5852 has an “angle” icon representing an option of setting the angle between the saw blade and a line perpendicular to the surface of the saw table (usually less than 90.degree.) and is correlated to thebutton5810. From thehome screen5816 shown inFIG. 58, when thebutton5810 is pushed, thehome screen5816 is replaced with anangle screen7500 shown inFIG. 75, and theuser interface5800 enters into an angle mode. Theangle screen7500 may then be replaced with other exemplary screens in an angle mode shown inFIG. 60 andFIGS. 76 through 83 when an appropriate button (or buttons) is pushed.
• As shown inFIG. 58, thetab5854 has a “height” icon representing an option of setting the height of the saw blade over the saw table surface and is correlated to thebutton5812. From thehome screen5816 shown inFIG. 58, when thebutton5812 is pushed, thehome screen5816 is replaced with aheight screen8400 shown inFIG. 84, and theuser interface5800 enters into a height mode. Theheight screen6300 may then be replaced with other exemplary screens in a height mode shown inFIG. 61 andFIGS. 85 through 94 when an appropriate button (or buttons) is pushed.
• As shown inFIG. 58, thetab5856 has a “gear” icon representing an option of adjusting the settings of thegraphic user interface5800 and/or the laser measurement and alignment device and is correlated to thebutton5814. From thehome screen5816 shown inFIG. 58, when thebutton5814 is pushed, thehome screen5816 is replaced with asettings screen9500 shown inFIG. 95, and theuser interface5800 enters into a settings mode. The settings screen9500 may then be replaced with other exemplary screens in a settings mode shown inFIG. 62 andFIGS. 96 through 101 when an appropriate button (or buttons) is pushed.
• The focus of the user interface is to provide a system which enables complex operations through an easy to use controller. In order to accomplish this goal the present invention has employed the standard of logically relating the folders which contain the various operational functions enabled by the user interface. For instance, after the user interface is calibrated ahome screen5816 provides access to distance modeFIGS. 63 through 74, angle modeFIGS. 75 through 83, height modeFIGS. 84 through 94, and settings modeFIGS. 95 through 101. When one of the modes is selected it provides access to the relevant operations pertaining to that mode in a clear and concise manner. Thus, the navigation through the complex user interface is made simple and provides a smooth flow of operation.
• Referring generally now toFIGS. 63 through 74, variousexemplary screens6300 through7400 of thedisplay5802 of theuser interface5800 in a distance mode are shown. Referring toFIG. 63, thedistance screen6300 is similar to thehome screen5816 shown inFIG. 58. However, in itssettings region5824 thedistance screen6300 shows thedistance mode icon5836 and itscorresponding value5838 only. In a preferred embodiment, when theuser interface5800 is in a distance mode, only thedistance mode icon5836 and itscorresponding value5838 are shown in the settings region5824 (see, e.g.,FIGS. 63 through 74). Preferably, a user sets only a desired distance between a saw blade and a fence of a table saw through theuser interface5800 when theuser interface5800 is in a distance mode. Because a user does not set an angle or a blade height in a distance mode, the angle and theheight mode icons5840,5844 and theircorresponding values5842,5846 do not need to be displayed on the screen in order to save battery power. Moreover, a screen in a distance mode showing only thedistance mode icon5836 and itscorresponding value5838 in thesettings region5824 may help a user to focus attention on setting the distance.
• As shown inFIG. 63, thedistance screen6300 has in its available-option region5826 fivetabs6302,6304,6306,6308, and6310 different from the five tabs shown inFIG. 58. Thetab6302 has a “home” icon unfilled with color representing an option of “returning to home directly” and is correlated to thebutton5806 directly below. When thebutton5806 is pushed, thedistance screen6300 is replaced with thehome screen5816 shown inFIG. 58. Thetab6304 represents an option of “fine adjustment” and is correlated to thebutton5808 directly below. Thetab6306 represents an option of “recall” and is correlated to thebutton5810 directly below. Thetab6308 has a “diskette” icon representing an option of “save” and is correlated to thebutton5812 directly below. As mentioned previously, it is contemplated that other removable memory media may be employed with the present invention, such as a DVD, CDR, flash media device, and the like. Therefore, the “diskette” icon may be altered to provide an alternative image more directly reflecting the current memory media being employed. Further, it is understood that the user interface may incorporate the usage of more than one type of memory media and thus include multiple memory media drives.
• Thetab6310 has a “back arrow” icon representing an option of “back one level” and is correlated to thebutton5814 directly below. That is, when thebutton5814 is pushed, theinterface5800 goes back one level and thedistance screen6300 is replaced with thehome screen5816 shown inFIG. 58.
• From thedistance screen6300 shown inFIG. 63, when thebutton5808 is pushed, thedistance screen6300 is replaced with a distancefine adjustment screen6400 shown inFIG. 64. As shown, thescreen6400 shows in its current-screen region5822 a textual representation “Fine Adjust”, indicating to a user that the current screen is for fine adjustment of a distance. Thescreen6400 has five tabs: thetabs6302 and6310 (as shown inFIG. 63), atab6402 for a “Zero” option correlated to thebutton5808, atab6404 for “Units” option correlated to thebutton5810, and atab6406 for “Offset” option correlated to thebutton5812. When thetab6302 is chosen (e.g., by pushing the button5806) from thescreen6400, theinterface5800 directly returns to home and thescreen6400 is replaced with thehome screen5816 shown inFIG. 58. When thetab6310 is chosen (e.g., by pushing the button5814) from thescreen6400, theinterface5800 goes back one level and thescreen6400 is replaced with thedistance screen6300 shown inFIG. 63.
• When the “Zero” option is chosen (e.g., by pushing the button5808) from thescreen6400, thescreen6400 is replaced with a distance relative zeroscreen6500 shown inFIG. 65. As shown inFIG. 65, thescreen6500 has in its current-screen region5822 a word “Zero”, indicating thecurrent screen6500 is a distance zero screen. Additionally, thescreen6500 has in its settings region5824 a letter “R”, indicating that thecurrent screen6500 is a distance relative zero screen. This is further shown by different representations of twonew tabs6502 and6504 on thescreen6500, where thetab6504 representing a distance relative zero option does not have a horizontal line above the word “Relative”, indicating the distance relative zero option is chosen. Using thebuttons5808 and5810, a user may toggle between the distance relative zeroscreen6500 shown inFIG. 65 and a distance absolute zero screen (not shown).
• When the “Units” option is chosen (e.g., by pushing the button5810) from thescreen6400, thescreen6400 is replaced with a default distance units screen6600 shown inFIG. 66. As shown inFIG. 66, thescreen6600 has in its current-screen region5822 a distance icon and a word “Units”, indicating thecurrent screen6600 is a distance units screen. Thescreen6600 includes three new tabs6602 (Frac),6604 (Dec) and6606 (mm), which represent a fraction unit option, a decimal unit option, and a metric unit option, respectively. Thetab6602 representing a fraction unit option does not have a horizontal line above “Frac”, indicating the fraction unit option is chosen. As a result of this option, the number in thedistance value5838 is displayed in a format of “integer+fraction” (see, e.g., “51/4” inFIG. 66).
• From thescreen6600 shown inFIG. 66, when thebutton5810 is pushed, thescreen6600 is replaced with a distancedecimal unit screen6700 shown inFIG. 67. As shown inFIG. 67, thescreen6700 has in its current-screen region5822 a distance icon and words “Dec Units”, indicating thecurrent screen6700 is a distance decimal units screen. Thetab6604 representing a decimal unit option does not have a horizontal line above “Dec”, indicating the decimal unit option is chosen. As a result of this option, the number in thedistance value5838 is displayed in a format of a decimal expansion (see, e.g., “5..sup.25” inFIG. 67). Using thebuttons5808,5810, and5812, a user may toggle among the default distance units (in fraction units)screen6600 shown inFIG. 66, the distance decimal units screen6700 shown inFIG. 67, and a distance metric unit screen (not shown).
• When the “Offset” option is chosen (e.g., by pushing the button5812) from thescreen6400 shown inFIG. 64, thescreen6400 is replaced with a distance offsetscreen6800 shown inFIG. 68. As shown inFIG. 68, thescreen6800 has in its current-screen region5822 a word “Offset”, indicating thecurrent screen6800 is a distance offset screen. Thescreen6800 includes a new tab6802 (Set), representing an option of adding an offset distance.
• From thedistance screen6300 shown inFIG. 63, when thebutton5810 is pushed, thedistance screen6300 is replaced with adistance recall screen6900 shown inFIG. 69. As shown, thescreen6900 shows in its current-screen region5822 a textual representation “Recall”, indicating to a user that the current screen is for recalling a saved distance. There may exist at least one saved distance value in a memory of theuser interface5800 or a memory of the laser measurement and alignment device communicatively coupled to theuser interface5800. Each saved distance value may have a label number such as 1, 2, 3, etc. For example, thescreen6900 shows a value5838 (“51/4″”) in itssettings region5824. The number “1” to the left of “51/4″” indicates that the label number for “51/4″” is “1”. Thescreen6900 includes two new tabs: atab6902 for a “+” option of moving to a saved distance value with a higher label number than that shown on the current screen, and atab6904 for a “−” option of moving to a saved distance value with a lower label number than that shown on the current screen. For example, from thescreen6900 shown inFIG. 69, when the “+” option (the tab6902) is chosen, thescreen6900 is replaced with ascreen7000 shown inFIG. 70, where a saved distance value with a higher label number “2” (“2 3/64”) is shown. Additionally, from thescreen6900 shown inFIG. 69, when the “+” option is repeatedly chosen several times (e.g., by pushing thebutton5808 several times), thescreen6900 may be replaced with ascreen7100 shown inFIG. 71, where a saved distance value with a higher label number “9” (“127/8″”) is shown. From thescreen7100 shown inFIG. 71, when the “−” option (the tab6904) is chosen, thescreen7100 is replaced with ascreen7200 shown inFIG. 72, where a saved distance value with a lower label number “8” (“33/8”) is shown.
• From thedistance screen6300 shown inFIG. 63, when thebutton5812 is pushed, thedistance screen6300 may be replaced with adistance save screen7300 shown inFIG. 73. As shown, thescreen7300 shows in its current-screen region5822 a diskette icon and a textual representation “Save”, indicating to a user that the current screen is for saving a distance value. Thescreen7300 includes a “diskette”tab7302, representing an option of saving the current value5838 (“61/2″”). When thetab7302 is chosen from thescreen7300, thescreen7300 is replaced with thescreen7400 shown inFIG. 74, where the value “61/2″” is given a label number (e.g., “11” shown inFIG. 74) and may be saved into a memory of theuser interface5800 or a memory of the laser measurement and alignment device communicatively coupled to theuser interface5800.
• It is contemplated that an operator of the user interface may input changes to the distance settings directly. For example, under the distance fine adjustment screen an alternative user input control mode may be included which allows the user to directly affect changes in the distance settings. The user may be enabled to make corrections to the distance in incremental amounts, such as ½ inch or ¼ inch, 0.1″ or 0.01″, or 10 mm or 5 mm. The user interface may provide “+” and “−” tabs correlated to user input control buttons which allow for this type of adjustment. The direct change of distance setting may be configured in a variety of ways and be within various locations of the height mode as contemplated by one of ordinary skill in the art.
• Referring generally now toFIGS. 75 through 83, variousexemplary screens7500 through8300 of thedisplay5802 of theuser interface5800 in an angle mode are shown. Referring toFIG. 75, theangle screen7500 is similar to thehome screen5816 shown inFIG. 58. However, in itssettings region5824 theangle screen7500 shows thedistance mode icon5840 and itscorresponding value5842 only. In a preferred embodiment, when theuser interface5800 is in an angle mode, only theangle mode icon5840 and itscorresponding value5842 are shown in the settings region5824 (see, e.g.,FIGS. 75 through 83). Preferably, a user sets only a desired angle between a saw blade and a line perpendicular to the table surface of a table saw through theuser interface5800 when theuser interface5800 is in an angle mode. Because a user does not set a distance or a blade height in an angle mode, the distance and theheight mode icons5836,5844 and theircorresponding values5838,5846 do not need to be displayed on the screen in order to save battery power. Moreover, a screen in an angle mode showing only theangle mode icon5840 and itscorresponding value5842 in thesettings region5824 may help a user to focus attention on setting the angle.
• As shown inFIG. 75, theangle screen7500 shows in its current-screen region5822 an angle icon and a textual representation “Angle”, indicating to a user that the current screen is in an angle mode. As shown, thescreen7500 has in its available-option region5826 fivetabs6302,6304,6306,6308, and6310 different from the five tabs shown inFIG. 58. Thetab6302 has a “home” icon unfilled with color representing an option of “returning to home directly” and is correlated to thebutton5806 directly below. When thebutton5806 is pushed, theangle screen7500 is replaced with thehome screen5816 shown inFIG. 58. Thetab6304 represents an option of “fine adjustment” and is correlated to thebutton5808 directly below. Thetab6306 represents an option of “recall” and is correlated to thebutton5810 directly below. Thetab6308 has a “diskette” icon representing an option of “save” and is correlated to thebutton5812 directly below. Thetab6310 has a “back arrow” icon representing an option of “back one level” and is correlated to thebutton5814 directly below. That is, when thebutton5814 is pushed, theinterface5800 goes back one level and theangle screen7500 is replaced with thehome screen5816 shown inFIG. 58.
• From theangle screen7500 shown inFIG. 75, when thebutton5808 is pushed, theangle screen7500 is replaced with an anglefine adjustment screen7600 shown inFIG. 76. As shown, thescreen7600 shows in its current-screen region5822 an angle icon and a textual representation “Fine Adjust”, indicating to a user that the current screen is for fine adjustment of an angle. Thescreen7600 includes three tabs: thetabs6302 and6310 (as shown inFIG. 75), and atab6402 for a “Zero” option correlated to thebutton5808. When thetab6302 is chosen (e.g., by pushing the button5806) from thescreen7600, theinterface5800 directly returns to home and thescreen7600 is replaced with thehome screen5816 shown inFIG. 58. When thetab6310 is chosen (e.g., by pushing the button5814) from thescreen7600, theinterface5800 goes back one level and thescreen7600 is replaced with theangle screen7500 shown inFIG. 75.
• When the “Zero” option is chosen (e.g., by pushing the button5808) from thescreen7600 shown inFIG. 76, thescreen7600 is replaced with an angle zeroscreen7700 shown inFIG. 77. As shown inFIG. 77, thescreen7700 has in its current-screen region5822 an angle icon and a word “Zero”, indicating thecurrent screen7700 is an angle zero screen. Thescreen7700 includes two new tabs: atab7702 representing an angle absolute zero option, and atab7704 representing an angle relative zero option. When thetab7704 option is chosen (e.g., by pushing the button5810) from thescreen7700 shown inFIG. 77, thescreen7700 is replaced with an angle relative zeroscreen7800 shown inFIG. 78. As shown inFIG. 78, thescreen7800 has in its current-screen region5822 an angle icon and a word “Relative”, indicating thecurrent screen7800 is an angle relative zero screen. Using thebuttons5808 and5810, a user may toggle between the angle relative zeroscreen7800 shown inFIG. 78 and the angle zeroscreen7700 shown inFIG. 77.
• From theangle screen7500 shown inFIG. 75, when thebutton5810 is pushed, theangle screen7500 is replaced with anangle recall screen7900 shown inFIG. 79. As shown, thescreen7900 shows in its current-screen region5822 an angle icon and a textual representation “Recall”, indicating to a user that the current screen is for recalling a saved angle. There may exist at least one saved angle value in a memory of theuser interface5800 or a memory of the laser measurement and alignment device communicatively coupled to theuser interface5800. Each saved angle value may have a label number such as 1, 2, 3, etc. For example, thescreen7900 shows a value5842 (“15.1.degree.”) in itssettings region5824. The number “2” to the left of “15.1.degree.” indicates that the label number for “15.1.degree.” is “2”. Thescreen7900 includes two new tabs: atab7902 for a “+” option of moving to a saved angle value with a higher label number than that shown on the current screen, and atab7904 for a “−” option of moving to a saved angle value with a lower label number than that shown on the current screen. For example, from thescreen7900 shown inFIG. 79, when the “+” option (the tab7902) is chosen (several times), thescreen7900 may be replaced with ascreen8000 shown inFIG. 80, where a saved angle value with a label number “5” (“30.0.degree.”) is shown. Additionally, from thescreen7900 shown inFIG. 79, when the “−” option (the tab7904) is chosen, thescreen7900 may be replaced with ascreen8100 shown inFIG. 81, where a saved angle value with a lower label number “1” (“7.5.degree.”) is shown.
• From theangle screen7500 shown inFIG. 75, when thebutton5812 is pushed, theangle screen7500 is replaced with an angle savescreen8200 shown inFIG. 82. As shown, thescreen8200 shows in its current-screen region5822 an angle icon and a textual representation “Save”, indicating to a user that the current screen is for saving an angle value. Thescreen8200 includes a “diskette”tab8202, representing an option of saving the current value5842 (“41.0.degree.”). As mentioned previously, it is contemplated that other removable memory media may be employed with the present invention, such as a DVD, CDR, flash media device, and the like. Therefore, the “diskette” icon may be altered to provide an alternative image more directly reflecting the current memory media being employed. Further, it is understood that the user interface may incorporate the usage of more than one type of memory media and thus include multiple memory media drives.
• When thetab8202 is chosen from thescreen8200, thescreen8200 is replaced with ascreen8300 shown inFIG. 83, where the value “41.0.degree.” is given a label number (e.g., “9” shown inFIG. 83) and may be saved into a memory of theuser interface5800 or a memory of the laser measurement and alignment device communicatively coupled to theuser interface5800.
• It is contemplated that an operator of the user interface may input changes to the angle settings directly. For example, under the angle fine adjustment screen an alternative user input control mode may be included which allows the user to directly affect changes in the angle settings. The user may be enabled to make corrections to the angle in incremental amounts, such as 0.5 degrees or 1 degree. The user interface may provide “+” and “−” tabs correlated to user input control buttons which allow for this type of adjustment. The direct change of angle setting may be configured in a variety of ways and be within various locations of the angle mode as contemplated by one of ordinary skill in the art.
• Referring generally now toFIGS. 84 through 94, variousexemplary screens8400 through9400 of thedisplay5802 of theuser interface5800 in a height mode are shown. Referring toFIG. 84, theheight screen8400 is similar to thehome screen5816 shown inFIG. 58. However, in itssettings region5824 theheight screen8400 shows theheight mode icon5844 and itscorresponding value5846 only. In a preferred embodiment, when theuser interface5800 is in a height mode, only theheight mode icon5844 and itscorresponding value5846 are shown in the settings region5824 (see, e.g.,FIGS. 84 through 94). Preferably, a user sets only a desired height of a saw blade over a table surface of a table saw through theuser interface5800 when theuser interface5800 is in a height mode. Because a user does not set a distance or an angle in a height mode, the distance andangle mode icons5836,5840 and theircorresponding values5838,5842 do not need to be displayed on the screen in order to save battery power. Moreover, a screen in a distance mode showing only theheight mode icon5844 and itscorresponding value5846 in thesettings region5824 may help a user to focus attention on setting the distance.
• As shown inFIG. 84, theheight screen8400 shows in its current-screen region5822 a height icon and a textual representation “Height”, indicating to a user that the current screen is in a height mode. As shown, theheight screen8400 has in its available-option region5826 fivetabs6302,6304,6306,6308, and6310 different from the five tabs shown inFIG. 58. Thetab6302 has a “home” icon unfilled with color representing an option of “returning to home directly” and is correlated to thebutton5806 directly below. When thebutton5806 is pushed, thedistance screen6300 is replaced with thehome screen5816 shown inFIG. 58. Thetab6304 represents an option of “fine adjustment” and is correlated to thebutton5808 directly below. Thetab6306 represents an option of “recall” and is correlated to thebutton5810 directly below. Thetab6308 has a “diskette” icon representing an option of “save” and is correlated to thebutton5812 directly below. Thetab6310 has a “back arrow” icon representing an option of “back one level” and is correlated to thebutton5814 directly below. That is, when thebutton5814 is pushed, theinterface5800 goes back one level and thedistance screen8400 is replaced with thehome screen5816 shown inFIG. 58.
• From theheight screen8400 shown inFIG. 84, when thebutton5808 is pushed, theheight screen8400 is replaced with a heightfine adjustment screen8500 shown inFIG. 85. As shown, thescreen8500 shows in its current-screen region5822 a height icon and a textual representation “Fine Adjust”, indicating to a user that the current screen is for fine adjustment of a height. Thescreen8500 has five tabs: thetabs6302 and6310 (as shown inFIG. 84), atab8502 for a “Zero” option correlated to thebutton5808, atab8504 for “Units” option correlated to thebutton5810, and atab8506 for “Offset” option correlated to thebutton5812. When thetab6302 is chosen (e.g., by pushing the button5806) from thescreen8500, theinterface5800 directly returns to home and thescreen8500 is replaced with thehome screen5816 shown inFIG. 58. When thetab6310 is chosen (e.g., by pushing the button5814) from thescreen8500, theinterface5800 goes back one level and thescreen8500 is replaced with theheight screen8400 shown inFIG. 84.
• When the “Zero” option is chosen (e.g., by pushing the button5808) from thescreen8500, thescreen8500 is replaced with a height absolute zeroscreen8600 shown inFIG. 86. As shown inFIG. 86, thescreen8600 has in its current-screen region5822 a height icon and a word “Zero”, indicating thecurrent screen8600 is a height zero screen. Additionally, thescreen8600 has in its settings region5824 a letter “A”, indicating that thecurrent screen8600 is a height absolute zero screen. This is further shown by different representations of twonew tabs8602 and8604 on thescreen8600, where thetab8602 representing a height absolute zero option does not have a horizontal line above the word “Absolute”, indicating the height absolute zero option is chosen. Using thebuttons5808 and5810, a user may toggle between the height absolute zeroscreen8500 shown inFIG. 85 and a height relative zero screen (not shown).
• When the “Units” option is chosen (e.g., by pushing the button5810) from thescreen8500, thescreen8500 is replaced with a default height units screen8700 shown inFIG. 87. As shown inFIG. 87, thescreen8700 has in its current-screen region5822 a height icon and a word “Units”, indicating thecurrent screen8700 is a height units screen. Thescreen8700 includes three new tabs8702 (Frac),8704 (Dec) and8706 (mm), which represent a fraction unit option, a decimal unit option, and a metric unit option, respectively. Thetab8702 representing a fraction unit option does not have a horizontal line above “Frac”, indicating the fraction unit option is chosen. As a result of this option, the number in theheight value5846 is displayed in a format of “integer+fraction” (see, e.g., 2 1/16″ inFIG. 87).
• From thescreen8700 shown inFIG. 87, when thebutton5810 is pushed, thescreen8700 may be replaced with a heightdecimal unit screen8800 shown inFIG. 88. As shown inFIG. 88, thetab8704 representing a decimal unit option does not have a horizontal line above “Dec”, indicating the decimal unit option is chosen. As a result of this option, the number in thedistance value5838 is displayed in a format of a decimal expansion (see, e.g., “5..sup.25” inFIG. 88). Using thebuttons5808,5810, and5812, a user may toggle among the default height units (in fraction units)screen8700 shown inFIG. 87, the height decimal units screen8800 shown inFIG. 88, and a height metric unit screen (not shown).
• When the “Offset” option is chosen (e.g., by pushing the button5812) from thescreen8500 shown inFIG. 85, thescreen8500 is replaced with a height offsetscreen8900 shown inFIG. 89. As shown inFIG. 89, thescreen8900 has in its current-screen region5822 a height icon and a word “Offset”, indicating thecurrent screen8900 is a height offset screen. Through thescreen8900, a user may add an offset height.
• From theheight screen8400 shown inFIG. 84, when thebutton5810 is pushed (and possibly after some other manipulations of the user interface controls5804), theheight screen8400 may be replaced with aheight recall screen9000 shown inFIG. 90. As shown, thescreen9000 shows in its current-screen region5822 a height icon and a textual representation “Recall”, indicating to a user that the current screen is for recalling a saved height. There may exist at least one saved height value in a memory of theuser interface5800 or a memory of the laser measurement and alignment device communicatively coupled to theuser interface5800. Each saved height value may have a label number such as 1, 2, 3, etc. For example, thescreen9000 shows a value5846 (“2 1/16″”) in itssettings region5824. The number “16” to the left of “2 1/16″” indicates that the label number for “2 1/16″” is “16”. Thescreen9000 includes two new tabs: atab9002 for a “+” option of moving to a saved height value with a higher label number than that shown on the current screen, and atab9004 for a “−” option of moving to a saved height value with a lower label number than that shown on the current screen. For example, from thescreen9000 shown inFIG. 90, when the “−” option (the tab9004) is chosen repeatedly, thescreen9000 may be replaced with ascreen9100 shown inFIG. 91, where a saved height value with a lower label number “5” (“23/4″”) is shown. Additionally, from thescreen9000 shown inFIG. 90, when the “+” option (the tab9002) is chosen repeatedly, thescreen9000 may be replaced with ascreen9200 shown inFIG. 92, where a saved height value with a higher label number “21” (“1 1/64″”) is shown.
• From theheight screen8400 shown inFIG. 84, when thebutton5812 is pushed, theheight screen8400 may be replaced with a height savescreen9300 shown inFIG. 93. As shown, thescreen9300 shows in its current-screen region5822 a height icon and a textual representation “Save”, indicating to a user that the current screen is for saving a height value. Thescreen9300 includes a “diskette”tab9302, representing an option of saving the current value5846 (“2 1/16″”). When thetab9302 is chosen from thescreen9300, the current value “2 1/16″” may be given a label number and may be saved into a memory of theuser interface5800 or a memory of the laser measurement and alignment device communicatively coupled to theuser interface5800. As mentioned previously, it is contemplated that other removable memory media may be employed with the present invention, such as a DVD, CDR, flash media device, and the like. Therefore, the “diskette” icon may be altered to provide an alternative image more directly reflecting the current memory media being employed. Further, it is understood that the user interface may incorporate the usage of more than one type of memory media and thus include multiple memory media drives.
• FIG. 94 shows another exemplary height savescreen9400, where a current value “⅝″” is given a label number (“12”) and may be saved into a memory of theuser interface5800 or a memory of the laser measurement and alignment device communicatively coupled to theuser interface5800.
• It is contemplated that an operator of the user interface may input changes to the height settings directly. For example, under the height fine adjustment screen an alternative user input control mode may be included which allows the user to directly affect changes in the height settings. The user may be enabled to make corrections to the height in incremental amounts, such as ½ inch or ¼ inch, 0.1″ or 0.01, 5 mm or 10 mm. The user interface may provide “+” and “−” tabs correlated to user input control buttons which allow for this type of adjustment. The direct change of height setting may be configured in a variety of ways and be within various locations of the height mode as contemplated by one of ordinary skill in the art.
• Referring generally now toFIGS. 95 through 101, variousexemplary screens9500 through10100 of thedisplay5802 of theuser interface5800 in a settings mode are shown. Referring toFIG. 95, the settings screen9500 shows in its current-screen region5822 a settings icon and a textual representation “Settings”, indicating to a user that the current screen is in a settings mode. As shown, the settings screen9500 has in its available-option region5826 fivetabs6302,9502,9504,9506, and6310 different from the five tabs shown inFIG. 58. Thetab6302 has a “home” icon unfilled with color representing an option of “returning to home directly” and is correlated to thebutton5806 directly below. When thebutton5806 is pushed, the settings screen9500 is replaced with thehome screen5816 shown inFIG. 58. Thetab9502 represents an option of “(global) Units” and is correlated to thebutton5808 directly below. Thetab9504 represents an option of “Calibration” and is correlated to thebutton5810 directly below. Thetab9506 represents an option of “System” and is correlated to thebutton5812 directly below. Thetab6310 has a “back arrow” icon representing an option of “back one level” and is correlated to thebutton5814 directly below. That is, when thebutton5814 is pushed, theinterface5800 goes back one level and the settings screen9500 may be replaced with thehome screen5816 shown inFIG. 58.
• From the settings screen9500 shown inFIG. 95, when the “Units” option is chosen (e.g., by pushing the button5808), thescreen9500 may be replaced with a default global units screen (see, e.g.,9600 shown inFIG. 96). As shown inFIG. 96, thescreen9600 has in its current-screen region5822 a settings icon and a textual representation “Global Units”, indicating thecurrent screen9600 is a global units screen. Thescreen9600 includes three new tabs9602 (Frac),9604 (Dec) and9606 (mm), which represent a global fraction unit option, a global decimal unit option, and a global metric unit option, respectively, for both adistance value5838 and aheight value5846. Thetab9602 representing a global fraction unit option does not have a horizontal line above “Frac”, indicating the fraction unit option is chosen. As a result of choosing this option, the number in a distance value5838 (and/or a height value5846) is displayed in a format of “integer+fraction” (see, e.g., “ 1/16” for adistance value5838 inFIG. 96, where the integer is not shown because the integer is zero).
• From thescreen9600 shown inFIG. 96, when thebutton5812 is pushed, thescreen9600 may be replaced with a global metric units screen (see, e.g.,9700 shown inFIG. 97). As shown inFIG. 97, thetab9606 representing a global metric unit option does not have a horizontal line above “mm”, indicating the global metric unit option is chosen. As a result of this option, a distance value5838 (and/or a height value5846) is displayed in a metric unit (see, e.g., “1.58 mm” inFIG. 97, where mm is millimeter). Using thebuttons5808,5810, and5812, a user may toggle among a default global units (in fraction units) screen (see, e.g.,9600 shown inFIG. 96), a global metric units screen (see, e.g.,9700 shown inFIG. 97), and a global decimal units screen (not shown).
• When the “Calibration” option is chosen (e.g., by pushing the button5810) from thescreen9500 shown inFIG. 95, thescreen9500 may be replaced with a calibration screen (see, e.g.,5600 shown inFIGS. 56, and5700 shownFIG. 57). Through a calibration screen, a user may perform all kinds of calibrations to a height, an angle, and a distance. Additionally, theuser interface5800 may have a drop-down menu (not shown) on thedisplay5802 to enable a user to select a calibration parameter from the drop-down menu. For example, a drop-down menu may provide kerf information for various kinds of saw blades, fence orientation information (horizontal or vertical), fence type (Unifense, Biesemeyer fence, or the like). Additionally, a saw blade may have a bar code or a RFID (Radio Frequency Identification) number attached to the saw blade body. When a saw blade is scanned by a bar code scanner or a RFID scanner, as the laser source employed by the present invention may be (shown and described previously inFIGS. 15 through 19), the relevant information (e.g., kerf, and the like) may be automatically entered into theuser interface5800 to enable theuser interface5800 to perform the calibration automatically.
• From the settings screen9500 shown inFIG. 95, when the “System” option is chosen (e.g., by pushing the button5812), thescreen9500 may be replaced with a system screen (see, e.g.,9800 shown inFIG. 98). As shown inFIG. 98, thescreen9800 has in its current-screen region5822 a settings icon and a textual representation “System”, indicating thecurrent screen9800 is a system screen. Thescreen9800 includes threenew tabs9802,9804 and9806, which represent a sound option, a brightness option, and a laser time out option, respectively.
• From thesystem screen9800 shown inFIG. 98, when thetab9802 is chosen (e.g., by pushing the button5808), thescreen9800 may be replaced with a sound screen (see, e.g.,9900 shown inFIG. 99). As shown inFIG. 99, thescreen9900 has in its current-screen region5822 a sound icon and a textual representation “Sound”, indicating thecurrent screen9900 is a sound screen. Thescreen9900 includes two new tabs9902 (“+”) and9904 (“−”), which represent an option of increasing a sound volume and an option of decreasing a sound volume, respectively. Thescreen9900 includes a bar-type scale9906 showing the current scale of the volume being “5”. By pushing thebutton5808 from thescreen9900, thetab9902 is chosen and the sound volume is increased to a scale larger than “5”. By pushing thebutton5810 from thescreen9900, thetab9904 is chosen and the sound volume is decreased to a scale smaller than “5”. When the scale is decreased to zero (“0”), the sound is turned off.
• The sound feedback mechanism provided by theuser interface5800 presents an audible signal to a user when a tool is in the selected position (e.g., when a saw blade has a desired height or angle, when a fence is in a desired distance from a saw blade, or the like). In a variation of this mechanism, the sound feedback mechanism may emit via a microphone/speaker a series of beeps or other noises to a user that guide the user in the positioning of the tool. For example, the beeps may become louder, more frequent, and/or change in pitch the closer the tool is to the desired position.
• Alternatively, theuser interface5800 may provide visual feedback mechanism (not shown) which presents a visual signal on itsdisplay5802. For example, this visual signal may be as simple as a light or other symbol being displayed on thedisplay5802 when the tool is in the desired position. In a variation of the visual feedback mechanism, arrows or other visual direction-guiding signals may be presented on thedisplay5802 to guide the user to the desired position of the tool.
• From thesystem screen9800 shown inFIG. 98, when thetab9804 is chosen (e.g., by pushing the button5810), thescreen9800 may be replaced with a brightness screen (see, e.g.,10000 shown inFIG. 100). As shown inFIG. 100, thescreen10000 has in its current-screen region5822 a brightness icon and a textual representation “Brightness”, indicating thecurrent screen10000 is a brightness screen. Thescreen10000 includes two new tabs10002 (“+”) and10004 (“−”), which represent an option of increasing screen brightness and an option of decreasing screen brightness, respectively. Thescreen10000 includes a bar-type scale10006 showing the current brightness scale being “8”. By pushing thebutton5808 from thescreen10000, thetab10002 is chosen and the screen brightness is increased to a scale larger than “8”. By pushing thebutton5810 from thescreen10000, thetab10004 is chosen and the screen brightness is decreased to a scale smaller than “8”.
• From thesystem screen9800 shown inFIG. 98, when thetab9806 is chosen (e.g., by pushing the button5812), thescreen9800 may be replaced with a laser time out screen (see, e.g.,10100 shown inFIG. 101). As shown inFIG. 101, thescreen10100 has in its current-screen region5822 a laser time out icon and a textual representation “Laser Time Out”, indicating thecurrent screen10100 is a laser time out screen. Thescreen10100 includes two new tabs10102 (“+”) and10104 (“−”), which represent an option of increasing a time period for laser time out and an option of decreasing a time period for laser time out, respectively. Thescreen10100 includes a bar-type scale10106 showing three time periods for laser time out: 10 seconds, 30 seconds, and 60 seconds. The current time period for laser time out is shown to be “30 seconds” inFIG. 101. That is, the laser measurement and alignment device will be turned off after it is on for 30 seconds. By pushing thebutton5808 from thescreen10100, thetab10102 is chosen and the time period for laser time out is increased to “60 seconds”. By pushing thebutton5810 from thescreen10100, thetab10104 is chosen and the time period for laser time out is decreased to “10 seconds”. An alternative embodiment of the bar-type scale10106 is shown in10100 ofFIG. 62, where the current time period for laser time out is shown to be “10 seconds”, and a user may use thebutton5808 to increase this time period and may use thebutton5810 to decrease this time period.
• It is understood that the foregoing-described screens shown inFIGS. 55 through 101 are intended as exemplary only and not as a limitation to the present invention. Those of ordinary skill in the art will appreciate that various combinations and arrangements may be employed without departing from the scope and spirit of the present invention.
• Referring, generally, now toFIGS. 102 through 106, table sawassembly11000,11100,11200,11300, and11400, are shown. It is contemplated that alaser apparatus11002, similar to the laser apparatus shown and described inFIGS. 1 through 12, one or more laser light indicia and readingassembly11102,11202, and11204, similar to the laser light indicia and reading assemblies shown and described inFIG. 13 through 24, and a bevel indication assembly, similar to the bevel indication assembly shown and described inFIGS. 8 through 12B, may be operationally coupled to auser interface11010,11110,11210,11310, and11410, similar to the user interface shown and described inFIGS. 47 through 101, respectively.FIG. 105 illustrates a first exemplary bevel indication assembly including alaser assembly11302 communicatively coupled with theuser interface11310. Thelaser assembly11302 includes a laser source which emits anincident laser beam11312, saidlaser beam11312 operationally contacting avisual indicator11314. Thelaser assembly11302, in the current embodiment, includes an imaging assembly for providing a visual image which may be displayed on theuser interface11310.FIG. 106 illustrates a second exemplary bevel indication assembly including asensor assembly11402. Communicatively coupled with theuser interface11410, thesensor assembly11402, in the present embodiment, may provide beveled angle information.
• InFIGS. 102 through 106, the exemplary user interfaces are shown enabling the user to conveniently obtain distance, blade height, and beveled angle measurements. The exemplary user interfaces are equipped with multiple selectors, such as the large push buttons, and an operating menu, as outlined inFIGS. 47 through 101. The user interfaces may be positioned at a remote location from the devices it is operationally coupled with, such as on a wall or on a tool belt. The user interfaces may also be positioned on various assemblies, such as a table saw assembly, and the like, with a flexible stand, enabling the user interface to be re-positioned as the user desires.
• It is understood that the various devices may be communicatively coupled with the user interface through a variety of communication assemblies. For instance, a wireless communication assembly may utilize various technologies, such as Bluetooth, radio frequency, infrared, and the like. It is further contemplated that the communicative link may be established utilizing serial cable, optical fiber cable, and the like.
• FIG. 105 illustrates atable saw assembly11300 including a bevel indication assembly including alaser source11302 and avisual marker11314, said laser source is communicatively coupled with auser interface11310. Thelaser source11302 further includes animaging device11303, such as a camera, which further communicatively couples with theuser interface11310. In the preferred embodiment, theimaging device11303 mounts onto thelaser source11302 which is coupled with anadjustable flange11307.

By having theimaging device11303 communicatively coupled to theuser interface11310, the user can view thevisual marker11314 from an area remote to the table sawassembly11300. Adisplay screen11316 is included with theuser interface11310 to show the user a real-time picture of thevisual marker11314. Therefore, when thelaser source11302 emits alaser beam11312 onto thevisual marker11314, theimaging device11303 may relay a picture to theuser interface11310 so that the user may view the visual marker's read-out. This embodiment is advantageous because theuser interface11310 may be positioned in a location remote to thevisual marker11312 such as on a wall, on a different part of the table sawassembly11300, or on the user's body.
• In alternative embodiments, the establishment of a wireless communication link between theuser interface11310 and thelaser source11302 and theimaging device11303 may enable these features to be mounted in various positions of the table sawassembly11300. For example, thelaser source11302,imaging device11303, andvisual marker11314 may be internally mounted to acabinet11305 of the table sawassembly11300. This may increase the ease of use of the table sawassembly11300 and may reduce the chances of unwanted contact with the various components of the bevel indication assembly.
• To further explain the embodiment shown inFIG. 106, thesensor assembly11402 may replace thelaser source11302 andvisual marker11314 of the exemplary bevel indication assembly shown inFIG. 105.

For instance, one sensor may represent ten degrees while another may represent twenty degrees. As theadjustment flange11412 rotates with thecircular saw blade11408, the sensor that corresponds to the actual beveled angle, will be activated. Once activated theuser interface11410 recognizes which sensor has sent a signal and displays the corresponding beveled angle, on adisplay screen11414. Thesensor assembly11402 may provide the beveled angle without requiring thevisual marker11314 ofFIG. 105. It is contemplated that thesensor assembly11402 may be mounted entirely on the inside of acabinet11405 of the table sawassembly11400, and theuser interface11410 may be positioned so that it is readable from any position.

As shown, the user input controls include aselector assembly13506 which, in the preferred embodiment, includes a plurality of push (or enter)buttons13508,13510,13512,13514, and13516. Thebuttons13508 through13516 enable a user to select or toggle between the screens and modes displayable on thedisplay13504, and to select input values for any of the available options, as discussed in more detail subsequently. InFIGS. 129 through 142, thebuttons13508 through13516 are positioned at the bottom of thehousing13502 and correlate with an option on thedisplay13504 available for selection by the user. However, thebuttons13508 through13516 may be positioned anywhere on thehousing13502 of theuser interface13500 as may be contemplated by a person of ordinary skill in the art. In the exemplary embodiment shown, thebuttons13508 through13516 are all enter buttons. However, it is within the scope of the present invention that other configurations and numbers of buttons may be used. Similarly, other forms of user input controls may be used, such as slides, track balls, switches, and pointing devices. Of course, although the described user interface is relatively large and complex, it is also possible to provide a much smaller user interface with less information displayed at a time.
• As previously described,FIG. 56 illustrates a default, or “Calibrating” screen of thedisplay5802. It is contemplated that this screen may be the initial display provided to a user and from which the user accesses the various functional capabilities of theuser interface5800 and13500. Access to the various modal functionalities to be described below in reference toFIGS. 129 through 142, may be made from this initial display and user input controls. For example, a user may access the modal functionalities of theuser interface13500 by “pushing” thebutton5814 which accesses the modal “Settings” screen which may provide various alternative modal options, which are displayed on the screen. Under the “Settings” screen, the user may be further enabled to select various secondary modal options which may enable thedisplay13504 with various secondary screens which display information (i.e., various secondary modal functionalities) which will be described below in reference toFIGS. 129 through 142. It is understood that the default “Calibration” screen may be the screen to which theuser interface5800 and13500, defaults after the user inputs are completed on any of the subsequently described screens. It is further contemplated that various other screens, such as the “Settings” screen, may be the default screen after user inputs without departing from the scope and spirit of the present invention.
• The display13504 (and hence each screen of the display13504) may include a battery region and a developer region as described previously for theuser interface5800.
• The battery region, which may be a sub-cell of the display screen or a designated exclusive region of the display screen, may provide a user with information about the status of batteries used to provide power to theuser interface13500. It is contemplated that the battery region may be configured to provide power information relating to the status of various devices, such as thelaser apparatus100, laser light indicia and reading assemblies described throughout the present disclosure, and the various other laser assemblies described throughout the present disclosure, with which theuser interface13500 may be communicatively coupled. This feature is useful to allow a user to monitor the status of the battery during use. In particular, a user may want to check the remaining battery capacity before starting a project that may require more battery reserve than currently available. It is understood that the battery region and textual/graphic display representation may be positioned on thedisplay13504 as may be contemplated by a person of ordinary skill in the art.
• The developer region, which may be a sub-cell of the display screen or a designated exclusive region of the display screen, may provide information about the developer of theuser interface13500. Alternatively, the developer region may be not included in thedisplay13504. In another embodiment the developer region may provide an indication of ownership of the individual user interface. For example, a user may place a specific logo in this region to identify theuser interface13500 as their own. It is understood that the location of the developer region on thedisplay13504 may vary. Further, each user interface may be enabled with a security feature which allows the individual unit to be protected from unauthorized use by another. For example, the security feature may include a user being able to enter a password into theuser interface13500 which is required before operation of the user interface will be allowed. It is contemplated that other security features may be incorporated into the present invention as contemplated by one of ordinary skill in the art.
• The display13504 (and hence each screen of the display13504) may include a variety of cells and/or sub-cells, within a single, dual, or tri-screen mode, providing numerous capabilities, for example an available-option region13520, a current-screen region13540, adescriptive identifier region13550, asettings region13560, and amode icon region13570. For each screen of thedisplay13504 of theinterface13500, the available-option region13520 includes a plurality of tabs used to show available options a user may have from the current screen. Each of the tabs may use an icon, textual, and/or graphic representation to indicate an option available from the current screen. The tabs may be established in a designated region or within a cell or sub-cell of the various screen modes which may be established upon the graphical user interface of the present invention. Each of the tabs is correlated to a user input control (e.g., a button, touch pad, and the like). To choose an option representing a tab, a corresponding user input control may be operated on (e.g., a corresponding button is pushed, or the like). In the preferred embodiment, each tab is correlated to a button directly below. This correlation of location, establishing a user input control in direct physical proximity to the tab, provides an ease of use of the present invention generally not seen in the art.
• The current-screen region13540 is used to show the screen status of theuser interface13500. It is contemplated that theavailable options region13520 and other regions described below may be incorporated, such as through the establishment of sub-cells, into the current-screen region13540. Thedescriptive identifier region13550 displays the various current operating modes made available by theuser interface13500 to the user. For example, thedescriptive identifier region13550 identifies “SCREEN” as the current operational mode of theuser interface13500 inFIG. 129. It is further contemplated that thedescriptive identifier region13550 may be enabled as a first displaydescriptive identifier region13552 and a second displaydescriptive identifier region13554 and may display other relevant information, such as “Distance” and “Height” as shown inFIG. 134. Various other configurations as contemplated by those of skill in the art may be enabled in the descriptive identifier region(s). In the preferred embodiment, thedescriptive identifier region13550 is a separate region (cell and/or sub-cell) of thedisplay13504.
• Thesettings region13560 displays information to the user about the current setup of programmed and user-selected modes for the tool (e.g., a table saw, or the like). As shown inFIGS. 130,134-138, and140-142 the settings region (settings cell/sub-cell)13560 may be disposed in the first (cell/sub-cell)display region13542, the second (cell/sub-cell)display region13544, or both the first and second cell/sub-cell display regions at the same time. Further, thesettings region13560 may include a firstdisplay settings region13562 and a seconddisplay settings region13564. The first and second display settings regions may partially encompass the first and/or second cell/sub-cell display region13542 and13544. However, the first and second display settings regions may encompass the entire first and/orsecond display region13542 and13544, as shown inFIGS. 137,138,141, and142. As illustrated inFIGS. 137,138,141 and142, the first and second cell/sub-cell display regions may be further delimited by one or more sub-sub-cell regions13565,13566, and13567, within which various types of information may be displayed in the settings region without departing from the scope and spirit of the present invention. It is understood that the configuration, including the number and size of cell, sub-cell, and/or sub-sub-cell regions, may vary to accommodate varyingdisplay13504 configurations.
• Referring now toFIGS. 134,136,138,140, and142, thedisplay13504 of theuser interface13500 may be enabled to establish various settings in thesettings region13560. For example,FIG. 134, shows theuser interface13500 enabled in a dual-cell screen mode displaying distance and height information. The first cell/sub-celldisplay settings region13562 provides information related to the distance measurement while the second cell/sub-celldisplay settings region13564 provides information related to the height measurement. Other dual-cell screen mode displays may be enabled as shown in the figures identified above and contemplated by those of ordinary skill in the art.
• It is further contemplated that thesettings region13560 may be enabled to provide user selectable inputs. As illustrated inFIG. 135, the first and second cell/sub-cell display settings regions include an identification of the angle of the blade, as presented, and enable a user to select “Y” if the angle is correct or “N” if the angle is incorrect. Additionally, the box provided in the second cell/sub-celldisplay settings region13564, next to the “N”, may be enabled to display multiple options for consideration and selection by the user. For example, if the user selects “N” then the box region may display a numerical angular representation, such as that shown in box next to the “Y” in the first cell/sub-celldisplay settings region13562. The user may be enabled, through use of the buttons of theselector assembly13506, to adjust the numerical angular representation in the box of the second cell/sub-celldisplay settings region13564 to a preferred value and then have that value established by the tool to which theuser interface13500 is coupled.
• Themode icon region13570 may provide a textual and/or graphic representation of various modal functionalities enabled by theuser interface13500. In the preferred embodiments, the modal functionalities include “distance”, “height”, “angle”, “bevel”, and “diameter”. For example, inFIG. 130, the mode icon region establishes a first exemplary icon for distance, while inFIG. 134 a second exemplary icon for distance is shown. It is contemplated that other modal functionalities may be enabled by the present invention as contemplated by those of ordinary skill in the relevant art. It is further contemplated that themode icon region13570 may include a first cell/sub-cell displaymode icon region13572 and a second cell/sub-cell displaymode icon region13574. It is understood that the configuration, including the number and size of cell/sub-cell mode icon regions, may vary to accommodate varyingdisplay13504 configurations.
• Referring now toFIG. 129, theuser interface13500 is operationally enabled in the “SCREEN” mode, as identified by thedescriptive identifier region13550. In this mode the user is enabled to select the configuration of thedisplay13504. Theavailable options region13520 presents the user with five tabs to select from. Afirst tab13522 presents an iconic “home” option, asecond tab13524 presents a first screen configuration option, athird tab13526 presents a second screen configuration option, afourth tab13528 presents a third screen configuration option, and a fifth tab presents a “forward arrow” option. The five tabs are operationally coupled with the fivepush buttons13508 through13516, of theselector assembly13506, respectively. Thus, a user may select one of the five options presented on the five tabs by pushing the corresponding button which is located directly under the tab.
• It is understood that thefirst tab13522 may be configured for the “home” option, as shown throughout theFIGS. 129 through 142, or thefirst tab13522 may be alternately configured. The “home” option of thefirst tab13522, if selected by the user, instructs theuser interface13500 to display the home screen. The home screen may be the “Calibration” screen described previously or various other screens which may be determined by those of ordinary skill in the art. It is contemplated that thefirst tab13522 which is labeled with the “home” icon may be filled with a color different from the background, indicating the current screen is the home screen. Moreover, thefirst tab13522 may be marked differently when the user interface is displaying the home screen, for instance thefirst tab13522 may include a horizontal line above the “home” icon to indicate that the current screen is the home screen. Thus, thebutton13508, when pushed, instructs theuser interface13500 to display the home screen as correlated with the “home” option identified on thefirst tab13522.
• In the present embodiment, thesecond tab13524 presents a single-cell screen mode option. Thus, if the user pushed thesecond button13510, which is correlated with thesecond tab13524, while in this screen mode, thedisplay13504 is configured as a single-cell screen and presents the information in accordance with this display configuration. If the user pushed thethird button13512, which is correlated with thethird tab13526, thedisplay13504 is configured as a split screen or dual-cell screen. In the present embodiment, thethird tab13526 does not have a horizontal line above it representing that this is the currently displayed configuration. The split screen configuration is shown inFIGS. 129 through 142. If the user selects thefourth button13514, which is correlated with thetab13528, thedisplay13504 is configured to provide three separate displays of information, as shown and described inFIGS. 47 through 101. Thefifth button13516 correlates with a “forward arrow” icon displayed in thefifth tab13530. The selection of the “forward arrow” results in theuser interface13500 moving out of the “SCREEN” mode and to another mode, such as those previously described or those described below. It is contemplated that selection of one of the buttons, other than the fifth button, may enable theuser interface13500 to move out of the “SCREEN” mode and into an alternative mode. Further, a selection made in the “SCREEN” mode may enable theuser interface13500 to display a specific screen, such as the “home” screen, from which further operations may be performed.
• When enabled in the “Units” mode thedisplay13504 may provide a default distance units screen, as shown inFIG. 130. As shown inFIG. 130, the screen has in the mode icon region13570 a distance icon and “Units” is displayed in thedescriptive identifier region13550, indicating the current screen is a distance units screen. Four of the tabs of theavailable options region13520 are reconfigured to display “Units” options on thedisplay13504 when in the “Units” mode. Thesecond tab13524 includes a “Frac” which represents a fraction unit option, thethird tab13526 includes a “Dec” which represents a decimal unit option, and thefourth tab13528 includes an “mm” which represents a metric unit option. Further, the fifth tab has a “back arrow” icon representing an option of “back one level” and is correlated to thebutton13516 directly below. That is, when thebutton13516 is pushed, theinterface13500 goes back one level. The screen displayed, after selecting to go back one level, may depend on where in the hierarchy of screens (seeFIG. 55) the “Units” mode screen, as displayed, is located.
• Thetab13524 representing a fraction unit option does not have a horizontal line above “Frac”, indicating the fraction unit option is chosen. As a result of this option, the number in the firstdisplay settings region13562, which represents a distance value is displayed in a format of “integer+fraction” (see, e.g., “51/4” inFIG. 130). If the third or fourth tabs were selected then the display of units may be altered to provide information in a decimal format or a metric format, respectively.
• FIG. 131 illustrates theuser interface13500 enabled in a “Laser” mode, as identified in thedescriptive identifier region13550. In the “Laser” mode thefirst display region13542 establishes alaser picture13580 representation of the laser device being employed in communication with theuser interface13500. In the present embodiment, thesecond tab13524 includes a “Sing” which represents that a laser device being employed is enabled to establish a single laser beam. Thethird tab13526 includes a “Plur” which represents that a laser device being employed is enabled to establish a plurality of laser beams. Thethird tab13526 is shown without the horizontal line above it indicating that the laser device being employed may establish multiple laser beams. Thus, thepictorial representation13580 is of a laser device establishing three laser beams. If thesecond tab13526 was selected thepictorial representation13580 includes a laser device emitting a single laser beam. In the present embodiment, thefourth tab13528 is shown with no representation included. It is understood that the tabs may be variously configured and that in the various modes enabled by the user interface13500 a tab may not provide a functionality. Further, it is understood that theuser interface13500 may enable a user to program various functionalities into locations, such as tabs, of theuser interface13500 without departing from the scope and spirit of the present invention.
• FIG. 132 illustrates theuser interface13500 enabled in a “Camera” mode, as identified in thedescriptive identifier region13550. In the “Camera” mode thefirst display region13542 establishes apicture representation13582 of a camera device being employed in communication with theuser interface13500.

The two illustrated mode icons aredistance13576 andheight13577, each of which having a corresponding value, similar to that shown and described previously in reference toFIGS. 47 through 101, and may trigger the display of one or more additional screens, as described in more detail subsequently. Similarly,FIG. 140, directed to the router mode, displays first and second mode icon regions, however, these icon regions are height and diameter. It should be understood that the textual names for the modes may be used in place of or in conjunction with the mode icons. Additionally, althoughFIGS. 134 and 140 shows a mode icon positioned below its corresponding value, other arrangements may be utilized as may be contemplated by a person of ordinary skill in the art. For example, a mode icon (and/or textual name) may be positioned to the left, to the right, or above its corresponding value without departing from the scope and spirit of the present invention. In the embodiments ofFIGS. 135 and 136 thecurrent screen region13540 includes theoperational mode icon13578, displayed in both the first and second display mode icon regions. Themode icon13578 represents the angle each of which has a corresponding value, similar to that shown and described previously in reference toFIGS. 47 through 101, and may trigger the display of one or more additional screens.
• Preferably, the distance value, the angle (bevel) value, height value, and diameter value in thesettings region13560 are all displayed in a clear fashion to a user so that the user is not confused by the numbers inside these values. Different fonts, sizes, and/or color may be used to distinguish different numbers. It is understood that visual clarity and the ease with which an operator of theuser interface13500 may view the information presented on thedisplay13504 may implicitly establish a preferable range of fonts, sizes, and colors used by the user interface. Further, the amount of information to be presented on each screen of thedisplay13504 may determine/establish a range of fonts, sizes, and colors to be used. This is another example of the user focus of the present invention, making complex technology available in a simple and effective manner. If a number is presented as an integer plus a fraction, the integer may be preferably presented in a larger font than a numerator and a denominator of the fraction. For example, as shown inFIG. 134, the distance value is “6.sup.⅛” in which the number “6.sup.⅛” is an integer “6” plus a fraction “.sup.⅛”, and the height value is “1.sup. 3/16″” in which the number “1.sup. 3/16” is an integer “1” plus a fraction “.sup. 3/16” The integers “6” and “1” are presented in a larger font than the numerators “1” and “3” and the denominators “8” and “16” so that a user is not confused by the numbers in the values. Moreover, if a value includes a decimal expansion of a number, the decimal digit(s) before the decimal point may be preferably presented in a larger font than the decimal digit(s) after the decimal point. It is understood that other methods as may be contemplated by a person of ordinary skill in the art may be used to distinguish numbers in a value so that a user is not confused by those numbers.
