Abstract

A wireless damper include a register, a controller regulating the amount of air flow provided by the register, and a radio frequency communications circuit. The radio frequency communications circuit provides a signal to the controller to adjust the air flow. A register regulation mechanism opens and closes the register in response to a signal from the controller to regulate air flow through the damper. The register regulation mechanism can be a variable switch, that adjusts the amount of air flow through the damper or a magnetic latch. A battery supplies power to the controller, the register regulation mechanism, and the radio frequency communications circuit.

Description

• This application claims priority from U.S. Provisional Application No. 60/174,829, filed Jan. 7, 2000; No. 60/176,005, filed Jan. 14, 2000; and No. 60/180,281, filed Feb. 4, 2000, the entire disclosures of which are incorporated by reference.[0001]
TECHNICAL FIELD
• This invention relates generally to building automation, and more particularly to a retrofit damper system for use in building automation.[0002]
BACKGROUND
• Building automation concepts have been known for some time. However, in general, these concepts have been limited to large industrial settings or to custom-designed systems for luxury homes because of the prohibitive cost associated with conventional automation systems. In addition, automation systems generally have been placed in new structures because of the substantial wiring necessary to implement these systems. Retrofitting automation systems in existing structures has been unpopular because, in general, the procedure is invasive and may require destruction of interior surfaces, substantial rewiring, significant expense, and inconvenience to the homeowner or tenant.[0003]
SUMMARY
• In one general aspect, a building automation system accommodates existing appliances at a cost that is affordable to the average homeowner or small business. In addition, the automation system can be installed in a home or a building without substantial rewiring, expense, or invasiveness. The automation system allows control of all associated systems from a remote location using virtual controls that resemble the actual controls of the appliances and have a consistent appearance between most interfaces. As a result, a user can operate and monitor systems without having to be present on site and without having to learn how to operate new controls. The automation system also can monitor the use of all home appliances and provide this information to a monitoring facility or a service provider. As a result, the monitoring facility or the service provider can provide a service to the user at a time when the service would be most beneficial to the user. In addition, by monitoring specific use of home appliances and user activities, companies can offer the user better service through the use of interactive coupons, warranties, improved maintenance, repair information, and interactive messaging.[0004]
• In one general aspect, a wireless damper includes a register, a controller regulating the amount of air flow provided by the register, and a radio frequency communications circuit. The radio frequency communications circuit provides a signal to the controller to adjust the amount of air flow. A register regulation mechanism opens and closes the register in response to a signal from the controller to regulate air flow through the damper. The register regulation mechanism can be a variable switch, which variably adjusts the amount of air flow through the damper and a magnetic latch.[0005]
• A battery supplies power to the damper, the controller, the register regulation mechanism, and the radio frequency communications circuit. The controller may monitor a power level of the battery. To do so the controller may send a signal for transmission by the radio frequency communications circuit when the power level reaches a predetermined amount. The controller may open the register if the power level of the battery reaches the predetermined amount.[0006]
• The damper may include a sensor for determining a condition at the damper. The controller may adjust the register regulation mechanism in response to the condition determined by the sensor. The controller receives the determined condition from the sensor and may send a signal with the determined condition to the radio frequency communications device for transmission of the determined condition signal. The condition sensed may be temperature.[0007]
• The radio frequency communications circuit may be a radio frequency transceiver.[0008]
• The controller may include a processor. The processor may send a signal to the radio frequency communications circuit identifying the damper. The processor also may determine if a signal received by the radio frequency communications circuit is addressed to the damper. The controller may include a memory for storing damper identification. The processor may determine if a signal is addressed to the damper using the stored damper identification.[0009]
• In another general aspect, a wireless air flow control system may include a wireless damper including a battery, and a zone controller. The zone controller sends a signal to the wireless damper to control the amount of air flow through the damper.[0010]
• The wireless air flow control system may include a display on which the zone controller displays a message identifying that the damper's battery power level is low or needs replacing.[0011]
• The wireless air flow control system may include a user interface. The user interface generates a signal and the zone controller controls the damper in response to the user interface generated signal. The user interface can be a thermostat or a computer.[0012]
• The wireless air flow control system also may include a control server. The control server controls the zone controller in coordination with other building functions under control of the control server.[0013]
• The wireless air flow control system may include a building air flow generation mechanism. The zone controller opens and closes the damper in response to activation and deactivation of the air flow generation mechanism.[0014]
• The wireless air flow control system may include a processor that sends a signal to a zone controller to identify the damper. The processor can determine if a signal received by the radio frequency communications circuit is addressed to the damper.[0015]
• Other features and advantages will be apparent from the description, the drawings, and the claims.[0016]

DETAILED DESCRIPTION
• System Overview[0045]
• An automation system, which may also be referred to as a building control (BC) system, may be used to automate a home, an office, or another type of commercial or residential building. In the residential context, the BC system establishes a home network that controls, coordinates, facilitates, and monitors user-designated activities within the home. The BC system provides compatibility between external and internal networks, systems, and appliances, and is modular in construction to allow easy expansion and customization. The BC system can be retrofitted for use in existing structures and legacy appliances without the need for drastic remodeling, added wiring, or complicated installation/customization, and can be installed by a homeowner with minimal instruction. Professional installation and maintenance also are simplified, so as to avoid the high costs typically associated with custom home automation.[0046]
• The modularity of the BC system provides for easy customization for either commercial or residential use. For residential applications, system elements may be sealed for easy installation, configuration, and aesthetic appearance. Expansion within the residential applications can be accomplished by adding new modules to the system. On the other hand, for commercial or advanced residential applications, the system can be custom configured and expanded through the additional use of expansion boards, PCMCIA cards, or plug in solutions. Although the following examples are primarily described with reference to home applications, the described devices and concepts also are applicable for commercial use.[0047]
• The BC System[0048]
• Referring to FIG. 1, an exemplary BC system is based around a[0049]control server100 that manages a number of primary networks including: an internal home network1 (e.g., a USB or Ethernet network), a video distribution network2 (e.g., Peracom AvCast System), a power line carrier (PLC)network3, a wireless radio frequency (RF)communications network4, and an Internet portal5 (e.g., a DSL modem). BC system devices attach to thecontrol server100 through one of these networks, and each network services a different aspect of home automation.
• The[0050]home network1 can include aresidential broadband gateway105 for high-speed interaction with the Internet and service providers. In addition, a number ofcomputer systems190 can be connected to provide access to thecontrol server100 and between thecomputer systems190. Thehome network1 can be implemented using any LAN system, such as, for example, an Ethernet system. Thecomputer system190 can be used as an interface for controlling home automation and running home automation software.
• The[0051]video distribution network2 can include anAvCast subcomponent180 that plugs into thecontrol server100 to coordinate multimedia activity between, for example, video monitors182 and asatellite TV system181. Thevideo distribution system2 also can act as an interface to thecontrol server100.
• The[0052]PLC network3 provides control ofswitches171,power outlets172, andsmart appliances135. In addition, a number ofcommunications modules120 can be used to communicate with legacy devices, such as arange130. Retrofit plugs125 also can be used within the PLC network to provide communication with legacy devices. A number of different interfaces, such as, for example,touch pads152,154 andportable tablet150, can be used to provide for user interaction with the control server.
• The[0053]RF network4 includescommunications modules120,legacy appliances132, and interfaces152 and154. In addition, auniversal controller110 can be used to control appliances, such as afurnace131. TheRF network4 can be connected withsensors141,143, and145 to monitor home utilities such as electricity, gas, and water, respectively. Asmart thermostat133 and a damper system can be used to control and optimize home heating and cooling.
• The[0054]Internet portal5 allows access and control of the BC system from a remote location. In addition, service providers may remotely monitor appliances, usage, and security within the home. New applications and upgrades of existing software can be obtained through the Internet.
• BC Controller/Server[0055]
• The[0056]control server100 is the core of the BC system. Thecontrol server100 provides multi-protocol routing and supervisory control for communicating appliances and general purpose device controllers. Thecontrol server100 is responsible for communicating with subordinate system devices while making data available to other supervising devices. The supervising devices include local user interfaces or Internet-based remote interfaces.
• The[0057]control server100 features pre-configured control function blocks or objects, in addition to user defined control strategies, that run on a real time control engine capable of executing combinational and sequential logic control. The control engine may be application specific or generic depending on the size and the intended purpose of the BC system in which the control engine is implemented. The control function blocks executed by thecontrol server100 are designed to operate in a number of modes, such as, for example, an away mode, a sleep mode, and a vacation mode, among others. Thecontrol server100 operates appliances and subsystems based on the BC system's current operating mode. For example, when entering the away mode, thecontrol server100 can activate the security system and turn down the heat or the air conditioning. In addition to modes that can be selected and transitioned, “hard-wired” functions are provided to initiate actions based on recognition of certain external conditions. One example of such an action is the flashing of red screens on all televisions and displays in a home when a fire alarm is tripped.
• The[0058]control server100 also provides for protocol conversion. For example, if an attached appliance has a stripped-down protocol, thecontrol server100 adds the missing elements to make the appliance appear to be compliant with a desired industry standard protocol. Where the physical layer necessary for communication with a device is not available in thecontrol server100, add-on units may be used to attach the control server to the device. Thecontrol server100 accommodates multiple protocols and physical layers throughcommunications modules120 attached between devices using foreign protocols or physical layers and thecontrol server100. Similarly, smart modules, retrofit plugs, and universal controllers may be used to provide the function of protocol conversion. Thecontrol server100 interfaces with any of the system graphic user interfaces (GUIs), PC networks, Internet, and all other portions of the BC system as described in greater detail below.
• The[0059]control server100 is modular in design and can be scaled with regard to size, functions, and hardware desired for a specific implementation. One example of acontrol server100 is shown in FIG. 2. As shown in FIG. 2, thecontrol server100 includes aprocessor200. Theprocessor200 is connected to a board with acommunications bus202, an I/O port203, and interfaces including a RF digital signal processor207, a 10 BASE-T interface206, amodem205, and aserial interface204. The interfaces provide communication between thecontrol server100 and the primary BC system networks1-5.
• The[0060]processor200 also is connected to aflash memory224, aRAM222, and anEEPROM220. An optional power source (RTC xtal and Battery)230 can be used to power thecontrol server100 in the event of loss of power. A number of communication ports are connected with the various interfaces. The communication ports can include a 10 BASE-T port212, aTELCO DAA214, a RS-232port216, a RS-485port218, and a S-BUS port (or USB port)219.
• In addition, a PLC controller[0061]280 and anEmWare Adapter260 are connected to the communications input/output port203. These devices may be configured on the board or as add-on modules. TheEmWare adapter260 can be used to communicate with and control appliances or systems that use an EmWare communications protocol. Other adapters for other communications protocol or systems can be provided in an original device or as addDocket on, plug-in applications. AVGA controller240 is provided for connection with aPC caster port242.
• As shown in FIG. 3, the[0062]control server100 also can be implemented as amain board300 with optional add on boards and PCMCIA slots. Themain board300 includes anEthernet connection301, a serial I/O port315, and an optional slot for aPC card305. Daughter boards are connected to the main board using a system bus connector. A daughter board typically includes an eight-way serial interface card and a four-way Ethernet card, with an optional slot for a PC card. Themain board300 can be implemented using a MotorolaMPC860 PowerPC core304, a memory (including flash306,DRAM308, NVRAM307), and I/O including: Dual SCC channels with HDLC interface, two status LEDs, two Tx/Rx pair communication status LED indicators, a debug RS-232 serial port, a PCMCIA slot, 10/100 Base T physical interface connector, an EIA-232 serial port, an EIA-485 serial port, and an EIA-485 serial port with 24V PSU input.
• External connections from the[0063]main board300 include a single RJ-45connector301 for an Ethernet connection and a number of RJ-11 connectors for serial communications. The first RJ-11connector303 can support two connections for 24V DC serial communication forPLC310 and asecond connector302 for an EIA-485 serial interface. The serial interfaces on themain board300 can use RJ-11 connectors. PLC interfaces to the main board, as well as other boards, are made through a serial interface to, for example, external communications modules. Theprimary PLC interface310 is enclosed inside the external transformer housing that provides 24V DC to the control server.
• Functionally, the Ethernet interface[0064]360 to themain board300 is the primary WAN or broadband interface. Typically, the interface360 can be connected to a cable modem or a DSL modem and can provide a firewall to secure data access. The EIA-232interface350 is provided for programming and debugging of thecontrol server100 in the field. The free EIA-485 interface allows flexible customization of thecontrol server100 or connection to an external POTS modem, a serial interface (third party device), or a second PLC.
• The[0065]control server100main board300 can accommodate a number of additional EIA-485 interfaces (e.g., eight interfaces). The additional interfaces can provide connection to third party devices, such as security panels, lighting control systems, HVAC zoning systems, and others. The additional interfaces also can be used for connection to external bridges, such as additional PLC interfaces, RF subsystems, communications modules, and retrofit plugs.
• The Ethernet board (not shown) on the[0066]main board300 includes four 10/100 base T Ethernet interfaces. The four interfaces provide connections for two secure LAN connections, one unsecure LAN connection, and one unsecure WAN connection.
• The control server video board (not shown) can include the following interfaces: video out/VGA out, video in, dual USB - printer, keyboard/mouse interface, IR interface, and PCMCIA slot (optional). The video board provides video I/O as well as IR command transmission. A keyboard and mouse combination can be used with the video board through a USB or USB-to-RF interface (in the case of a wireless keyboard or mouse). A second USB connector can interface with printers, digital cameras, and other peripheral equipment. Functionally, the board accepts video input and digitizes the video for use by the rest of the BC system using the MPEG4 standard. The video board also provides video output as a TV channel for broadcast on connected televisions within the home.[0067]
• Universal Controller[0068]
• The[0069]universal controller110 is an optimized form of thecontrol server100. Theuniversal controller110 performs a single dedicated task, such as HVAC control. As a result, theuniversal controller110 includes only the input and output features that are necessary for the dedicated task. Theuniversal controller110 can be used in a stand-alone configuration with access through remote dial-up, Internet access, and/or a touchpad interface. Theuniversal controller110 also can be controlled and monitored by thecontrol server100. Theuniversal controller110 communicates with the control server through the RF or PLC networks or by directly wired serial communication. Theuniversal controller110 can be used to handle applications that are pre-packaged for physical distribution, that have outgrown the capability of thecontrol server100, or that have special features not handled by astandard control server100. In addition, theuniversal controller110 can be implemented as a daughter board to thecontrol server100.
• According to the example shown in FIG. 4, the[0070]universal controller110 includes aprocessor400 to which amemory420 is connected. The memory includes communications software for the remote uploading and downloading of data and software for control of specific attached subsystems, such as, for example, HVAC control. Theuniversal controller110 also includes 16 analog/digital switches for receipt of signals from sensors. An RS-232communication interface430 is provided for PC, modem, and other communication with serial communication ports of other devices. Twenty four relays configured in pairs of twelve are provided asoutput440. Each relay in a pair can be configured for an individual device that is powered from a common source.
• Control Modules[0071]
• Referring again to FIG. 1, control modules (e.g.,[0072]120 and125) allow legacy appliances that have already been purchased by a homeowner or commercial operator to be integrated into a home automation system. This is important because appliances are expensive and have relatively long operational lives. As a result, appliances typically are not replaced until failure. Therefore, for existing appliances to be incorporated in a total home or commercial automation system, an interface is needed to allow communication with the automation system so that a user is not forced to buy a network ready appliance. The control modules provide such an interface in a form that can be installed easily by the homeowner or business operator.
• In addition, manufacturers may not wish to sell devices that are network/system compliant due to the added cost associated with outfitting the appliance with the necessary software and control circuitry. Therefore, a control module can be inserted into an appliance aftermarket, or by the manufacturer, to provide network protocol compliance.[0073]
• Two examples of control modules are the appliance communications module and the retrofit plug. The appliance communication module acts a bridge between the control server (or remote monitoring service provider) and an appliance by providing protocol conversion that is specific to the appliance. The communication module also allows the control server to control the appliance. The retrofit plug provides for remote monitoring and diagnosis of an appliance, and is easily installed with any appliance.[0074]
• Appliance Communications Module[0075]
• The[0076]appliance communications module120 is adapted to be received by an appliance having an appliance controller. Thecommunications module120 includes a communications protocol translator. The communications protocol translator translates signals received from a communications media into appliance controller signals. The translator also translates appliance control signals received from the appliance controller into a communications protocol to be output to an appliance communications network. Thecommunications module120 also can include a power line transceiver connected to the communications protocol translator and a power line driver connected to the transceiver and the connector. The communications module's connector is electrically coupled to the appliance controller. Alternatively, thecommunications module120 can include a radio frequency (RF) transceiver or modem for connection to an appliance network. An example of thecommunications module120 is shown in FIG. 5.
• The protocol translator translates signals received from the network into appliance controller signals. The translator also translates received appliance control signals according to a communications protocol to be output to the network through the modem or transceiver.[0077]
• A network ready appliance is also provided. The network ready appliance includes an appliance controller having a communications port. The appliance also includes a cavity, defined by walls, that is adapted to receive the[0078]communications module120. An opening in a wall of the appliance allows access to the cavity. A connector is attached to one of the cavity walls. A communications line connecting the communications port and the connector also is provided. The connector is electrically coupled to the appliance controller or to the main power supply. The network ready appliance further includes a detachable cover provided over the opening to protect a user from electric shock. Alternatively, the appliance connector can be recessed in a cavity to protect the user against shock.
• The communications module is described in detail in U.S. patent application Ser. No. 09/511,313 title “COMMUNICATION MODULE” which was filed Feb. 23, 2000, and is incorporated by reference in its entirety.[0079]
• Retrofit Plug[0080]
• The[0081]retrofit plug125, shown in FIGS.6A-6D, is a plug-through device that is either attached in line with the main appliance electrical supply or internally in line with a main control board interface connector of anappliance130. As shown in FIG. 6A, the retrofit plug can be installed on legacy equipment by simply connecting theretrofit plug125 to the pins of the appliance that are used to supply power to the appliance. As a result, a legacy appliance can be easily incorporated into a network to allow monitoring and control of the appliance by a homeowner without the need for custom or professional installation.
• As one example of an internal connection, control signals inside certain refrigerators pass through a marshalling connector connected to the main control board. By connecting a retrofit plug to this connector, all signals within the refrigerator can be tapped for diagnostic data. The diagnostic data may be sent to the[0082]control server100 that monitors theappliance130, for example, through thePLC network3. The data gathered from theappliance130 can be stored by thecontrol server100 or downloaded to a remote database maintained by a service provider.
• In a standalone application, the[0083]control server100 can be replaced by a gateway connected to a PLC network. Data from the retrofit plug can be sent through the PLC network to the gateway. The gateway transmits the data to a service provider monitoring theappliance130. The plug may operate as a stand-alone unit by equipping the plug with a modem to communicate with an external computer (e.g., as provided by a monitoring service). Theretrofit plug125 also can be equipped with an RF transceiver so that the plug may be incorporated in awireless network4 for monitoring and control of an associated appliance.
• FIG. 6B shows an[0084]exemplary retrofit plug125 that provides an interface between an appliance's electronic control system and thecontrol server100. Theretrofit plug125 has anouter housing600 made of, for example, an electrically-insulative plastic (class II) or (class I). The retrofit plug can include a number of couplers. For example, thehousing600 includesslots601 and602 for connection with pins from theappliance130, for example, on a power cord, that are used to supply power to theappliance130.Pins603 and604 extend from the housing for connection with the mains that supply power to theappliance130. Although only two pins and two slots are shown in the example of FIG. 6B-D, additional pins and slots may be included as needed to be compatible with any particular appliance's power supply. For example, a retrofit plug could attach to a three pin connector by adding an additional slot and pin for an earth connection or to a four pin connector having two live pins, a neutral pin, and a ground pin by adding slots and pins for the second live pin and the earth pin.
• The[0085]retrofit plug125 includes apower supply650 for supplying power to a measure and transmitcircuit620, a power line communication (PLC)transceiver630, and aline driver640. Thepower supply620 powers the retrofit plug's components (620,630, and640) by converting the appliance AC voltage (e.g., 100V to 264V and 50/60 Hz) to a 5/10V DC voltage. Thepower supply650 receives power frompins603 and604 throughlines641 and643.
• The retrofit plug includes monitoring circuitry. For example, a measure and transmit[0086]circuit620 is connected to a current transformer610 to measure the current being drawn by the appliance attached to theretrofit plug125. Other circuitry that could be used to monitor the current drawn by the attached appliance includes a Rogowski coil or a shunt.
• The measure and transmit[0087]circuitry620 may include a processor (e.g., an ASIC, a DSP, a microprocessor, or a microcontroller) and memory (such as an integrated circuit (IC) memory or a flash memory). The measure and transmitcircuit620 can simply monitor and report the current drawn by the attachedappliance130. Specifically, the measure and transmitcircuit620 may monitor current draw timing, duration, and amount. In more sophisticated applications, the measure and transmit circuit can be upgraded to perform bi-directional communication by translating between a communications media protocol used by thecontrol server100 and the appliance's control protocol. In addition, if the appliance's load current is measured, an indication of power can be derived from the square of the load current. Line voltage may be measured and multiplied by the load current to measure true power consumption.
• The current draw data or power data can be stored by the measure and transmit[0088]circuit620. The measure and transmitcircuit620 can be programmed to periodically send the measured data to thecontrol server100 as part of a general monitoring function, such as, for example, energy management and logging functions. In addition, the measure and transmitcircuit620 can be programmed to compare measurement data to specific electronic signatures stored in a table in the memory of theretrofit plug125. The measure and transmit circuitry can send messages to thecontrol server100 in response to events which indicate a state of theappliance130 requiring some further action (e.g., shut off power).
• The[0089]retrofit plug125 also includes a communications circuit. The communications circuit sends data from the measure and transmit circuit to a remote processor, such as, for example, thecontrol server100. The communications circuit may also receive signals from a remote processor, such as, for example, thecontrol server100. The communications circuit may include a transmitter and a receiver or a transceiver, a power line communication (PLC)transceiver630, and aline driver640. Measurement data is supplied to thePLC transceiver630 and are coded for PLC transmission on thePLC network3. ThePLC transceiver630 operates aline driver640. Theline driver640 places the measurement data as PLC coded signals onlines641 and643 according to a network protocol.
• The PLC coded signals are supplied by the retrofit plug to the external power circuit that supplies power to the appliance. The[0090]control server100 monitors the external power circuit to receive the PLC coded signals. In this way, thecontrol server100 can monitor appliances connected to the external power circuit and the appliances can exchange data with thecontrol server100 or other appliances connected to the network.
• The[0091]control server100 or a remote monitoring service is able to perform diagnostic interpretation about theappliance130. In this manner, the BC system can determine the health of the appliance, the appliance's current function (e.g., how many burners are on, oven capacity, temperature monitoring in a refrigerator, and washer and drier cycles including length), and device failure (including cause). For example, if a current signature or power usage for the light bulb in a refrigerator is detected as being active over an extended period of time, thecontrol server100 can determine that an open door condition exists and can generate a message for display on aninterface150 to alert the user to shut the door.
• The[0092]retrofit plug125 also can include a power-switching device under control of the measure and transmitcircuit620. The power-switching device enables remote shutdown of the attached appliance, for example, through theretrofit plug125, if a situation occurs that may damage the appliance if operation is continued or if a hazardous condition may result from continued operation. The power-switching device also can permit dimming and variable current flow regulation for remote control of the appliance.
• The[0093]retrofit plug125 can be designed specifically for a particular appliance. As a result, theretrofit plug125 can perform sophisticated diagnosis, monitoring, and control specific to the appliance. Alternatively, theretrofit plug125 can contain sufficient memory that control data or programs can be downloaded to the plug from thecontrol server100 through the PLC network. The software and data may be provided directly by the service provider. Software also may be installed in the field using a flash memory chip that is inserted into theretrofit plug125.
• As shown in FIG. 6C, an[0094]optional battery655 can be connected with thepower supply650 to provide power to components of the retrofit plug in the event that power is lost. The battery may be a rechargeable battery that charge while the retrofit plug is supplied with power, if the battery is not in a fully charged state.
• A serial port or other communications interface also can be provided in the retrofit plug to provide additional communication capabilities. The serial interface may be used for connection with another sensor to provide additional data about the device connected to the[0095]retrofit plug125. The additional data can be transmitted to a remote monitoring device using the PLC network.
• Other types of communications media also can be supported by the retrofit plug. As shown in FIG. 6C a[0096]modem670 is provided within theretrofit plug125 to provide communication to a network through a phone line. Alternatively, a wireless modem could be used for remotely located appliances where a phone line may not be available. The processor in the measure and transmitcircuit620 handles modem dial-up to an external network and provides buffering for the two-way data transfer on line671. A phone line can be attached to the data transfer line671 by adding a RJ connector in the housing of theretrofit plug125. Themodem670 does not have to be included within theretrofit plug125, instead, the modem can be a snap-on attachment to theretrofit plug125.
• As an example, the modified retrofit plug with serial port and modem can be used to monitor a commercial freezer. A[0097]retrofit plug125 is installed on the main power supply to the freezer. In addition, a temperature sensor is fitted inside the freezer compartment to measure the freezer's interior temperature. The temperature sensor is attached to theretrofit plug125 using the serial port. The battery provides power capability to theretrofit plug125 and its components. In addition, theretrofit plug125 has a telephone modem. In this case, if the main power supplied to the freezer fails and the freezer temperature approaches32 degrees, theretrofit plug125 can sense the rise in temperature using the remote temperature sensor and dial the operator or monitoring service to alert that food spoilage is possible.
• Operator Interfaces[0098]
• Operator interfaces that can be used with the BC system include, for example, single room touch pad, small touchpad, standard touchpad, portable tablet, PC, and web enabled phones. In general, the look and feel of the operator interfaces is consistent between each interface where possible, and may look as is shown in FIGS.[0099]7A-7C.
• Single Room Touchpad[0100]
• The single room touchpad is basic in design and is intended for installation into a standard light switch box. The touch pad is capable of controlling at least two functions such as temperature and lighting. The single room touchpad also can accommodate an intercom for communication between rooms in the home. Through use of RF or PLC communications, the touchpad may be sized to fit in a standard switch box for ease of installation and integration.[0101]
• Small Touchpad[0102]
• The basic functionality of the small touchpad is that of a home automation system controller or room controller. Where appropriate, colors and sounds can be used to catch a person's attention or to signal an alarm. An exemplary[0103]small touchpad154 is shown in FIG. 7A.
• The[0104]small touchpad154 includes a display, such as, for example, a 2.6″ color TFT display. Thedisplay701 shows the controls for lighting in a room. Aroom selection bar702 displays the area that the small touchpad is being used to control. Anarrow button703 allows the user to switch between multiple areas. Control bars are used to control appliances within the area, such as, for example, acontrol bar705 for overhead lighting and acontrol bar708 for a table light. The amount of overhead lighting can be adjusted by selecting the + or −buttons706 and707 on the display. Theside table light1 can be turned on or off using thebuttons709 and710 oncontrol bar708. Additional control bars, if any, can be accessed by using thedown arrow711. Aback button712 navigates the user to the previous display. Selections can be made by touching the screen using a stylus, a finger, or the like. Three buttons are provided for controlling the display of thesmall touchpad154.
• Standard Touchpad[0105]
• The[0106]standard touchpad152 is a sophisticated operator interface designed for more enhanced presentation of information. The standard touchpad includes a 4 inch, 320×240 pixel personal data assistant (PDA)-style display and is capable of displaying video images as well as textual or icon based images. It is also capable of presenting web content in the manner of alerts or breaking news items. Thestandard touchpad152 provides alarm and alert notification by means of color and sound, examples of which are:
• Red-Flashing with buzzer—extreme alarm such as fire or intrusion detection;[0107]
• Red with beeper—alarm such as system fault or pre-defined alarm condition (the two year old has entered the pool area);[0108]
• Yellow with beeper—general alert such as hurricane warning or other weather or news advisory; and[0109]
• Green with low level beeper—general information, such as clothes are ready from the dryer.[0110]
• Being more sophisticated, the[0111]standard touchpad152, which may be the only operator interface available, is not bound to controlling a single portion or subset of the BC system, and, instead, is capable of looking at the whole environment controlled by the BC system. It also is capable of configuring the system. An option for video display allows thestandard touchpad152 to present low-grade camera images such as, for example, from a camera positioned at the front door. A speaker and microphone can be included to provide an intercom with the video feature.
• The[0112]standard touchpad152 builds on the display of thesmall touchpad154. The standard touchpad includes adisplay731. Aroom selection bar732 appears at the top of the display. The user may switch between rooms using thearrow button733. Multiple control bars735-738 also are displayed. Additional control bars can be accessed by using thedown arrow741. Aback button742 is provided for navigating back to the previous display window. Fourkeypad input buttons744 are provided for immediate navigation to preset display windows and to manipulate thedisplay window731.
• The[0113]standard touchpad752 can be mounted onto a wall and hard wired. Thestandard touchpad752 also can be used as a portable unit having a cradle for storing and re-charging the unit when not in use.
• Portable Tablet[0114]
• A[0115]portable tablet150 can be used to communicate with the BC system provided that required connectivity options are available. Theportable tablet150 is used to present all aspects of the standard touchpad devices as well as more detailed configuration options. In addition, the portable tablet provides video and web browsing capabilities. The portable table may have a 12″ display and may be used in the distributed video network to control all televisions and video devices. As a result, a parent could use the portable tablet to flash a message on the children's TV—“its time for dinner.” The portable tablet may be implemented using a web pad.
• The web pad interface includes an applications bar[0116]756 that allows the user to switch between the various applications supported by the BC system. A tool bar75 for selecting specific features, such as, for example, a particular appliance to control, is provided on the top of the display. Aroom selector arrow753 also is provided. The portable table150 is able to display a number of control bars (754,755). A downarrow758 provides selection of additional control bars associated with the appliance, if necessary. Aback button757 is also provided to move to the previous display screen.
• Video Distribution Network[0117]
• As shown in FIG. 8, a BC system includes a[0118]control server100 connected to a number of primary networks including: anEthernet LAN1, aPLC LAN3, anRF LAN4, an RS-485 LAN, a WAN (connected by a POTS or ISDN line), and avideo distribution network2. Thevideo distribution network2 includes aAvCast daughter board180, amedia caster module810, acable caster module820, and aweb caster module830. TheAvCast daughter board180 plugs into a slot on thecontrol server100. TheAvCast daughter board180 can include the following interfaces: video out/VGA out, video in, dual USB—printer, keyboard/mouse interface, IR interface, and PCMCIA slot (optional). The video board provides video I/O as well as IR command transmission. A keyboard and mouse combination can be used with the video board through a USB or USB-to-RF interface (in the case of a wireless keyboard or mouse). A second USB connector can interface with printers, digital cameras, and other peripheral equipment. Functionally, the board accepts video input and digitizes the video for use by the rest of the BC system using the MPEG4 standard. The video board also provides video output as a TV channel for broadcast on connected televisions within the home.
• The[0119]media caster module810 is a digitally-tuned audio-video modulator with user-selectable UHF or CATV channels. Themedia caster module810 is individually addressable. Themedia caster module810 allows signals from thecontrol server100 to be displayed onTVs182 by converting the video output from thecontrol server100 to a TV channel. The resulting converted signal can be distributed to a number ofTVs182 using thecable caster module820. Using the output TV channel, thecontrol server100 can broadcast video data, virtual control panels, security camera video output, messages, alarms, and control interfaces to any connected BC system interface.
• The[0120]cable caster module820 provides bi-directional signal-splitting with 6 dB of amplification to compensate for cable loss. Thecable caster module820 distributes a video signal feed to anyconnected TV182 while providing enough amplification to ensure crisp TV pictures despite long cable runs and signal-splitting.
• The[0121]web caster module830 converts SVGA and audio inputs to a TV signal. The converted signal can be distributed tomultiple TVs182 and interfaces (e.g.,190 or150) using thecable caster module820. Theweb caster module830 allows the data displayed on aPC screen190 to be viewed on aTV182. As a result, theTV182 can be used as a second monitor for viewing, for example, web pages.
• A[0122]gateway105 offers broadband connection to a CATV system. Thegateway105 connects with thecontrol server100 through the high-speed Ethernet link1 using, for example, a Cat5 cable. When used with thevideo distribution network2, video signals can be routed through themedia caster module810 andcable caster module820 toother TVs182 using standard co-axial cable. In addition, the video signal from thegateway105 can be fed directly into thecable caster module820 for distribution by co-axial cable throughout a building.
• The[0123]gateway105 provides a high-speed link enabling services such as, for example, video on demand, from the CATV connection. The high-speed link also provides a fast Internet connection for browser software running on theportable tablet150 or the90. Services, such as teleshopping, can be provided through thevideo distribution network2, if supported by the cable service provider. Thegateway105 also provides a high-speed data link to the rest of thehome network1 supporting real-time video capability. Thegateway105 can be implemented as a standalone unit or as a plug-in module in the control server.
• Smart Appliances[0124]
• Smart appliances (e.g.,[0125]135) are network ready appliances that can be connected to the BC system without additional modification or interfaces. Once connected to the BC system, a smart appliance can be controlled by thecontrol server100. In addition, the smart appliance can be remotely controlled through use of a virtual control panel displayed on a BC system interface, such as aportable tablet150. A smart appliance has either a communications module or a smart module that connects to the internal appliance controller to provide compatibility with thecontrol server100. The smart module and virtual control panel are described in detail in copending U.S. application Ser. No. 09/378,509, titled “DISTRIBUTED LIFE CYCLE DEVELOPMENT TOOL FOR CONTROLS” which is incorporated by reference in its entirety.
• Retrofit Damper[0126]
• A wireless forced air damper for zoned HVAC control is shown in FIG. 9. The[0127]damper900 is available in industry standard sizes to replace floor, wall, or ceiling registers. Thedamper900 communicates with a smartHVAC zone controller133 using wireless RF communications signals901. Asensor910 can be placed in the area serviced by thedamper900 to report local conditions to thezone controller133. Thesensor910 communicates through theRF network3, thePLC network4, or through direct wiring tocontroller133. Alternatively, thesensor910 can be included in thedamper900 as described below. Additionally the sensor can be awireless sensor915. Thezone controller133 can be implemented as a stand-alone unit. Alternatively, thezone controller133 can be supervised by thecontrol server100. If incorporated in the BC system, thezone controller133 can be controlled by any of the BC system interfaces, such as theportable tablet150. In addition, home manager software can be used to controlzone controller133 according to a number of predetermined modes of operation. Thermostats can be provided to provide user control of individual zones within a building. Existingwired thermostats155 can be coupled to the zone controller to allow user control of the HVAC system. Additionally,wireless thermostats157 can also be used. Thewireless sensor915 andthermostat157 can be incorporated into a single unit.
• A block diagram of a[0128]damper900 is shown in FIG. 10. Thedamper900 includes aregister1010 for controlling air flow through thedamper900. AnRF transceiver1050 receives control signals901 from thezone controller133 and transmits status/sensed data to thezone controller133. Apower supply1030, such as, for example, a battery or other self-contained power source, powers the damper's electrical components so that the damper is self-contained and does not require any additional wiring for power. Amechanism1020, such as, for example, a solenoid, a spring, a shape memory wire, or a magnetic latching mechanism, is coupled to theregister1010. Themechanism1020 actuates the register to allow air flow in response to a signal received from thecontroller1040. A magnetic switch or latching mechanism having thousands of latching cycles may be used as themechanism1020 to reduce power consumption and to extend the operational life of the damper between replacing/recharging of thepower supply1030. For example, the latching system can have one or two magnets. A capacitor can be charged from the battery using a trickle charge. In response to a control signal the capacitor can cause an induction, which actuates the magnet that holds register in one operation state. A second magnet or gravity may be used to return the register to its other operational state. A variable mechanism also may be used to control the register such that the register can be partially opened to regulate air flow (e.g., 100% open, 80% open, 50% open, and closed).
• The[0129]controller1040 can monitor thepower supply1030. When thepower supply1030 reaches a minimum charge threshold, theregister1010 is placed in an open state so that theregister1010 is left in the open position if power fails. In addition, thecontroller1040 may notify thezone controller133 that the power supply has reached a minimum threshold. Once notified, thezone controller133 alerts the user that thepower supply1030 needs to be replaced/recharged. Alternatively, thezone controller133 may poll thedamper900 to send a measurement of the power supply's remaining charge to thezone controller133. Upon receipt of the measurement, thezone controller133 performs the threshold analysis and alerts the user if necessary. A cover or door that is accessible from the room is provided to ease access to thepower supply1030.
• When the fan unit on the air conditioner or the furnace is on, or when a preset condition occurs, the zone controller broadcasts a control signal to the[0130]controller1040 to cause the mechanism to activate theregister1010. In addition, thezone controller133 may selectively open orclose dampers900 based on a control program, a mode of operation, or upon a request from a user interface. Drain on the charge of the damper'spower supply1030 may be reduced by waiting until air flow has stopped before closing theregister1010 to limit the force needed to close theregister1010. Asensor1060 may be connected to thecontroller1040 to measure temperature at thedamper900. The measurement is supplied to thezone controller133 as input to zone and comfort control software operating in thezone controller133 or thecontrol server100.
• The[0131]zone controller133 is shown in FIG. 11. Thezone controller133 can be implemented using auniversal controller110. Thezone controller133 includes aprocessor1110 for controlling and monitoring thedampers900. Amemory1120 is provided to store climate control software and for operation and identification of thedampers900. AnRF transceiver1130 transmits control commands to and receives responses from the dampers in response to the commands. Thedampers900 are periodically polled by thezone controller133 for status and sensor data. The data can be stored in thememory1120 for analysis by theprocessor1110 or the data may be transmitted to thecontrol server100 for storage and analysis. If no response is received from adamper900 after being polled a number of times, thezone controller133 notifies the user orcontrol server100 that thedamper900 is not responding and may need servicing. An optional I/O interface1140 is provided for connection withexternal sensors910. An RS-232interface1150 allows peripheral equipment, such as a handheld unit or a modem, to be connected to thezone controller133. An RS-485 interface1160 is provided to connect thezone controller133 with thecontrol server100.
• Each[0132]damper900 is assigned a unique HVAC control ID number. Thezone controller133 uses the control ID number to identify a damper. Each installeddamper900 is dedicated to asingle zone controller133 and rejects interference from any other controllers, unless released by an authorized security code stored in thedamper900. Initial configuration of thedampers900 can be accomplished according to one of the following methods.
• According to a first method,[0133]zone controller133 is placed in an initialization mode. Once thezone controller133 has been placed in the initialization mode, thedampers900 can be powered up one at a time. Upon powering up, adamper900 broadcasts a message with the control ID to thezone controller133. Configuration software in thezone controller133 acknowledges the received broadcast message, stores the control ID, and prompts the user to identify the location of the damper. After the user enters the location, thezone controller133 awaits receipt of the next initialization message and repeats the process until the locations of alldampers900 are identified.
• According to another method, barcodes can be used to configure the[0134]dampers900 upon installation. When the damper is installed, a barcode on thedamper900 is scanned using a handheld device with a barcode reader. The barcode encodes the control ID for thedamper900. After reading the barcode, the handheld device prompts the installer to enter the location of thedamper900. The handheld device then associates the control ID with the entered location and stores this information in a table. Alternatively, barcodes identifying predetermined locations are placed in corresponding slots that accommodate thedampers900. The installer scans the barcode in a slot using the handheld device. The installer then scans a barcode on the damper to read the damper's control ID and associates the damper with the location. After installation of the dampers, the damper control ID and the location data are downloaded to thezone controller133 by connecting the handheld device to a port on thezone control133.
• According to another method, a barcode identifying the damper's control ID number can be peeled off the damper and placed on a location sheet. The sheet is scanned to determine a damper's control ID number and location. Once scanned, the data is downloaded to the[0135]zone controller133.
• After configuration of the dampers, according to any of the methods described above, the[0136]zone controller133 controls thedamper units900 through RF control signals according to the instructions of the zone controller's operational programming. Thezone controller133 can broadcast control messages that are addressed to all dampers, to a set of dampers, or to a specific damper using the control ID numbers.
• The above-described system is not limited to dampers. The control system could be applied to other flow control devices, such as hydronic systems using, for example, a valve instead of a register. Although the actuation devices and flow control mechanisms would be specific to the environment, the control circuitry and operation would be substantially the same.[0137]
• Home Manager Software[0138]
• The home manager software incorporates a number of fundamental modes of operation. Six exemplary modes are: a stay mode, an away mode, a bedtime mode, a sleep mode, a vacation mode, a wake-up mode, and a custom mode. The stay mode is configured to operate when the home is occupied. In this mode, certain aspects of the home, such as comfort control, are set automatically by the home manager. Other aspects, such as lighting scenes, are independent of the mode and are set either by the occupant or based on time of day occurrences.[0139]
• The away mode implies that the home is occupied but no one currently is at home. When operating in the away mode, the BC system can override other programming, such as, for example, lighting control, to simulate occupancy and to arm the security system. During operation in the away mode, other system operations, such as energy saving control, can conserve energy by cutting back on hot water or comfort settings.[0140]
• A bedtime mode (not to be confused with a sleep mode described below) can be incorporated in homes that have children. The bedtime mode is used when the children have gone to bed but there are still one or more adults awake in the home. Bedtime mode activates certain monitoring systems, such as, for example, child monitoring, checking to make sure certain televisions and other entertainment devices are off, and alerting the adults if certain lights come on (e.g., the children's rooms or bathrooms). Using this mode, parents can monitor sleeping children or be alerted when children wake up.[0141]
• Sleep mode is used to put the house to sleep. While in sleep mode, the BC system arms the security system, and ensures that all doors are closed and locked, all lights and appliances are off, and that comfort settings are altered appropriately.[0142]
• Vacation mode provides an enhanced state of security when a family is away from the home for an extended period of time. In this mode, lighting and entertainment systems may be used to simulate occupancy. Energy hungry systems, such as, for example, comfort control and hot water, may be reduced to minimum settings. Appliances may be monitored for unnatural activity, such as, for example, activation of the coffee pot (which normally would not switch on in the morning if the family were on vacation). However, the vacation mode can make allowances for house sitters who periodically bring in the mail or check on the house.[0143]
• Wake-up mode is a choreographed schedule of events that happens as the house leaves sleep mode and enters stay mode. A number of timed events take place in the wakeup mode that can be customized for any particular residence. For example, prior to the alarm clock going off, comfort settings can be altered. If an HVAC zoning system is in place, the comfort settings can be adjusted in bedrooms and bathrooms first. Wake-up mode then increases the setting for the hot water heater, turns on the coffee pot, and adjusts other home systems in preparation for a family getting out of bed. A typical wake-up schedule would include: determine wake-up time based on day and weather, increase hot water temperature, increase temperature in bathrooms, shut off electric blankets, turn on the coffee pot, ramp up lights to simulate sunrise, activate wake-up alarm, turn on televisions for news, adjust comfort control for whole house. This list is exemplary and not comprehensive as any particular residence has a unique sequence of events. Other features can be programmed into the mode as desired by either the user or the service provider.[0144]
• Custom modes also may be provided these modes may be programmed by the user, downloaded from a service provider over the Internet, or field programmed by a service provider technician on site.[0145]
• There are a number of hidden modes that are invoked by features within the home manager. An example of a hidden mode is the fire mode. If a fire is detected by the security system, lights are adjusted to aid exit, doors are unlocked, gas to the house is shut off, the HVAC systems are shut down, and emergency numbers are called. Other hidden modes include: distress (robbery), medical emergency, and appliance failure.[0146]
• Architecturally, each device connected to the BC system subscribes to the various features offered in the house manager modes through priority blocks. Each feature responding to a mode has an associated priority setting, for example, a security feature responding to a fire mode has a higher priority level than a bedtime mode setting. FIG. 12 shows the relative positioning of the modes, the various features running on the system, the prioritization of each feature, and control of the field device. Features shown as custom may require additional programming to interface to the home management software.[0147]
• Each feature also has an associated set of software functionality based on the hardware components available. The BC system automatically functions as described once the hardware is recognized by the BC system.[0148]
• Enhanced security beyond that provided by a conventional security system is provided by the home manager. The enhanced security feature may supplement a conventional security system present in the home that is connected to the[0149]control server100. Settings available in the enhanced security system include: armed/away mode, armed/stay mode, un-armed, system fault, medical emergency, police emergency, and fire emergency.
• The settings for the security system relate to home manager modes in the following way. Both vacation mode and away mode invoke the away setting in the security panel. Both the armed/home and un-armed settings relate to the stay mode for the home manager. Although the armed/home setting does not relate directly to a specific mode, it can be set either by the existing security system or by the home manager on an individual basis.[0150]
• The home manager can set or receive any of the armed/un-armed modes either locally or from a remote location (e.g., through a remote user or security service provider). Behavior of each of these sub-systems is described below.[0151]
• Gas Shut-off Valve[0152]
• In the fire emergency mode, the gas shut-off valve shuts-off the main gas supply to the house. This feature can be applied to any form of flammable fuel, such as natural gas, heating oil, or propane. In all other modes, the shut-off valve is in the normal state.[0153]
• Water Shut-off Valve[0154]
• In all modes, the shut-off valve is in the normal state.[0155]
• Lighting Interface[0156]
• In the armed/away setting, the lighting interface can be set to a pre-defined state. The predefined state can include setting individual lights on and off at prescribed times to simulated occupancy. To configure simulated occupancy, the lights are monitored for a period of one week, or as desired by the user. The light activity during this time is recorded by the[0157]control server100 and captured according to a homeowner prompt to copy the activity. After the activity has been stored in the control server database, mode the lights behave as they did during the recorded period whenever the security feature is placed in the away armed.
• In the fire emergency mode, perimeter (outside) lights are set to flash at a 50% duty cycle with a 1 second cycle time to attract attention to the home. In addition, lights designated as exit lights are set to a level prescribed by the homeowner. During system configuration, lights are defined as exit lights, perimeter lights, or normal lights. In this way, the homeowner can establish an escape route using the lighting. All other lights are shut off.[0158]
• In all other modes the lights are set in their normal state.[0159]
• Door Locks[0160]
• Doors are locked in the armed/away mode, and are unlocked in the medical emergency mode and the fire emergency mode. In all other modes, the door locks are in the normal state.[0161]
• HVAC Interface[0162]
• The HVAC interface can include communications to a sophisticated whole house HVAC zoning system or simply a connection to a programmable communicating thermostat. In the fire emergency mode, the HVAC system is shut down to prevent smoke from being distributed throughout the house. In all other modes, the HVAC system is in the normal state.[0163]
• Health Monitoring[0164]
• In the medical emergency mode, any health monitoring equipment that is connected to a person on a routine basis can be activated (if it isn't already). In all other modes, the monitoring equipment is in the normal state.[0165]
• Child Detection[0166]
• In the armed/stay mode, if a child is alone in the house, all cook tops are disabled from use without a password to unlock them. In the fire emergency mode, a security company is notified that a child is in the house. In all other modes, the child detection is in the normal state.[0167]
• Elder Tracking[0168]
• In the medical emergency mode, the security company will be notified that a elderly or disabled person is in the house. In the fire emergency mode a security company is notified that an elderly or disabled person is in the house. In all other modes, the elder tracking is in the normal state.[0169]
• Security Cameras[0170]
• Security cameras are accessible remotely by the BC system. The[0171]control server100 captures a camera image and digitizes it for local display or for access from a remote browser. Data compression can be used to save memory space. In the police emergency mode, the security cameras are automatically set to record on a suitable recording device, such as a VCR, if available. In all other modes, the security cameras are in the normal state.
• AVCast[0172]
• In the fire emergency mode, all television sets in the house are set to the control server TV channel. The control server displays the message “FIRE” on the television screens. If a location of the fire is known, that location is also placed on the screen, for example, “FIRE—basement”. In all other modes, the AVCast system is in the normal state.[0173]
• Away Mode Monitoring[0174]
• Away mode monitoring is not to be confused with the Armed/Away mode described in the enhanced security section. Away mode monitoring relates to the ability to monitor or control the home while away. The home manager supports a number of different hardware methods for this task including a high-speed broadband connection as well as telephone dialup. In either case, the[0175]control server100 provides firewall protection against unauthorized access. Away mode monitoring is also supported by web enabled phones or phones with a mini-browser capability. Any device with a browser can be used to access the home manager to control or monitor any aspect in the home.
• Appliance Maintenance[0176]
• Appliance maintenance allows for remote access of appliances within the home. Appliances can include, for example, any kitchen or laundry appliance, water heater, HVAC system, lighting, audio/visual, sprinkler, or comfort control. Connectivity to each appliance is provided by a telephone modem or a broadband connection to the control server, or the like. The[0177]control server100 acts as the interface to the appliances and serves as a firewall to prevent unwanted tampering. All appliance control functions available within the home are allowed from outside of the home provided that the user is authorized to do so. In the event that a catastrophic failure is detected, a service provider can shut-off gas or water to the house to prevent an explosion or water damage.
• Some appliances are capable of a certain amount of self-diagnosis, such as detecting a clogged filter. Under these conditions, the appliances can prompt the user to initiate repairs by displaying a message on a local user interface. In other instances, the appliance must be diagnosed either remotely or by a service provider on site. The control server's role in appliance diagnosis is to provide access to data by a remote site and to provide any necessary service prompts locally. The service provider may shut off the appliance if continued operation would damage the appliance.[0178]
• Enhanced Comfort[0179]
• Enhanced comfort control involves any aspect of home automation that automatically improves personal comfort. A number of devices, when connected to the[0180]control server100, can be incorporated into the enhanced comfort feature. Examples of such devices include HVAC control, programmable thermostats, a zone control system, ceiling fans, air filtering, humidity control, and automatic blinds.
• HVAC control encompasses the broadest aspect of comfort control. HVAC control also can be impacted by an energy management or an enhanced security feature, if available. Programmable communicating thermostats provide the greatest impact on the ability to manage comfort in the home. Fundamentally, the home manager communicates with the thermostat and allows the homeowner to program and configure the thermostat. In addition, other features within the home manager are able to override or alter the actions of the thermostat if needed, for example, when the enhanced security system shuts down the airblower in case of a fire. Under the energy management feature, the thermostat setting can be adjusted to shed load during high tariff conditions or when the home is unoccupied.[0181]
• Zoning control is a feature that can provide benefit to virtually every home. There are always instances where one area of the home is hotter or colder than another area. A zoning system uses temperature sensors and variable dampers to adjust the temperature of each zone independently. The home manager supports two forms of zoning: hardwired and wireless.[0182]
• A hardwired zoning system involves dampers installed inside ductwork communicating to the control server through a central HVAC zoning package, or directly through PLC communications. Similarly, the temperature sensors are connected to the[0183]control server100 either through PLC or through the zoning package.
• In the case of a wireless zoning system, RF communications are used to communicate to all temperature sensors and dampers. In this instance, the retrofit damper described above can be incorporated.[0184]
• Main HVAC control can be provided through direct connection from the[0185]control server100 to the HVACzone controller unit133 or to a communicating thermostat, which in turn controls the packaged unit. If thecontrol server100 is taken off-line for some reason, theHVAC zone controller133 or communicating thermostat can revert to a conventional operation mode.
• Other devices, such as, for example, ceiling fans, humidifier/de-humidifiers, air filters, adjustable skylights, and automatic blinds can respond to an algorithm for comfort control implemented in the[0186]HVAC controller110 or thecontrol server100.
• Energy Savings[0187]
• The primary method for achieving energy savings is to reduce settings or turn off large energy consuming appliances during non-critical times or peak tariff times. The away mode controlled by the home manager system can lower thermostats, reduce temperature of the hot water heater, coordinate HVAC and appliances based on peak tariff conditions by adjusting thermostats to appropriate extremes of the comfort zone, restricting use of appliances to off-peak times, using automatic blinds and skylights to reduce HVAC demand, and synchronizing HVAC and hot water heater control with the sleep mode by cutting back temperatures during sleep time and bringing them back up as part of the wake-up cycle.[0188]
• Family Manager[0189]
• The family manager can be used in conjunction with the away mode monitoring to allow family members to connect to the system remotely. The family manager manages family data and automates certain tasks, such as, for example, maintaining the family calendar, maintaining a family address book, maintaining a family task list with alarms and reminders, and providing a kitchen/laundry assistant. The family manager is capable of being sorted and searched in a variety of different ways. A family member can access the entire family task list or just the member's personal tasks.[0190]
• The family calendar contains events of the following profiles: single time events, periodic events (weekly, monthly, yearly), and alarmed events. Events can be assigned to one or more family members and carry details such as start time, end time, and priority. The family address book is segmented by family member and has annotations for entries related to, for example, family, business associates, service providers, theaters, and shops. Closely associated with the calendar is the task list. Tasks are assigned a degree of importance, time needed for completion, and family member assigned to the task.[0191]
• The kitchen and laundry assistant centers around maintaining an inventory of products in the home such as food and laundry supplies. The assistant maintains shopping lists and supports e-grocery and e-commerce. A method for scanning products, such as barcode or RF ID, is supported to introduce new products into inventory and remove them when discarded. Discarding or use of an item can automatically prompt e-commerce services for re-stocking. The kitchen assistant focuses on meal preparation by recommending recipes or compliments based on products in inventory. The kitchen assistant also supports recipe instructions accessed from Internet sites. A screen shot of the cooking assistant is shown in FIG. 14.[0192]
• Home Automation[0193]
• The home automation feature consists of a variety of modes that can be invoked from the stay mode, the bedtime mode, or the sleep mode. This feature consists of settings for groups of devices associated with certain activities. There are a number of default modes plus a set of user defined modes provided by this feature referred to as activity modes. Default activity modes include: television, reading, dinner, formal dinner, and party. The homeowner can add activity modes, such as, for example, gaming, for playing cards, or night swim, to turn on back yard lights.[0194]
• BC Systems[0195]
• Meter Network[0196]
• The meter network and its link to the control server is explained with reference to FIG. 15.[0197]Water meter1510 and heat meters (1520,1530) are connected with abus1501 output that allows the meters to be networked via Cat5 cable to abus master unit1500. Thebus master unit1500 converts the bus signals to a format readable by thecontrol server100. Theelectricity meter1540 has a pulse output that requires anadditional bus coupler1510. Thebus coupler1510 accumulates the pulses and allows connection to thebus1501. Each coupler has pulse inputs for up to 4 meters. Thebus1501 has an open protocol such that any product that conforms to bus standards can be connected to the network.
• Ideally the[0198]bus master unit1500 is located in the same position within the house as thecontrol server100 and connects to thecontrol server100 through one of the control server's RS-232 ports.
• The[0199]control server100 allows each meter to be read by an authorised external data collection service. As a result, a wide variety of monitoring services can be offered, such as, for example, data collection, data analysis, and payment. Such services benefit the end-user through improved visibility of energy usage leading to better energy management. The home manager software can display energy consumption data and trends and to give tips for reducing consumption.
• Energy DataVision (EDV) is an online data display package that enables energy users to monitor energy usage patterns via the web. IMServ's data collection service arm remotely interrogates metes to access meter reads. Each meter has an identification number assigned to it. The monitoring services is given an access code to log into the[0200]control server100 and use the EDV system to create a variety of reports regarding energy usage for the building. EDV can graph usage trends from month-to-month, day-to-day, date-to-date, hour-to-hour. An example of an EDV screen shot is shown in FIG. 16.
• Commercial diagnosis analysis is shown in FIG. 17.[0201]
• Central Locking and Door Access System[0202]
• The central locking system, shown in FIG. 18, includes an RF[0203]key fob1040, areceiver1810, a motorized door bolt, and sensors to detect an open/closed door, door bolt position, and open/closed windows. Abus coupler1830 is provided for connection to the motorized door bolt. The motorized door bolt is activated and deactivated using thekey fob1840. Thekey fob1840 transmits a lock signal and an unlock signal to theRF receiver1810. The RF receiver relays the signals to thecontrol server100 to control one or more motorized door bolts. The motorized door bolts also can be controlled using other BC system interfaces, such as, for example, a portable tablet150 (through control module120), aPC interface190, or through theInternet portal5. Asecond bus coupler1820 provides inputs from the widow and door sensors to thecontrol server100 indicating an open/closed state of the doors and windows.
• The[0204]control server100 can interface with an existing door access system by using one of the bus coupler outputs to trigger the door controller (i.e., the opening/closing mechanism). The central locking system allows the user to check that all windows and doors are in the correct position before automatically locking them. The samekey fob1840 can be used with the door access system to open the common access door either from inside or outside the building. This reduces the number of keys that need to be used in any one location.
• The key fob technology ensures security by appropriate coding. More than one key fob can be accommodated to allow each family member to have his or her own key. On activating the close function from the key fob, the[0205]control server100 checks that all doors and windows connected to the system are closed. A warning is given (e.g., by continually flashing the door/hall lights' if the all sensors do not detect a closed position. If all doors and windows are closed, the system activates the locks. After the locks have been activated another check is performed and if all doors have successfully locked and indication is given (e.g., flashing the door/hall tight once).
• In the event of a power failure, the doors remain secure but in the event of a fire or other emergency they are easily opened from the inside and do not impede an escape route.[0206]
• The home manager software for the[0207]control server100 can include the central locking features.
• House Security System[0208]
• A home security network is shown in FIG. 19. The required sensors can be hardwired to an existing[0209]electronic security system1900. Theexisiting security system1900 is linked into thecontrol server100 through aserial link1901. Alternatively, RF controlledmotion detectors1900 andsmoke detectors1920 can send signals to thecontrol server100 for analysis. Thecontrol server100 provides telephone connection and web services that are need for the security system. The status of the security system can be monitored by a remote server using theInternet portal5, dedicated ISDN, DSL, or POTS service, or any of the home interfaces, such asportable tablet150 orPC interface190.
• The existing network can be extended by adding the sensors to the appropriate LAN.[0210]
• In this case, the home manager software can be customized to provide specific system features tailored to the location. The security system using the[0211]control server100 can perform all standard functions such as intruder alarm (through door and window switches or motion detectors) and alarm generation (either locally or remotely).
• Lighting System[0212]
• A lighting network for use with the BC system is shown in FIG. 20. The lighting network comprises a[0213]lighting system LAN2000. A number of bus couplers are connected to thelighting system LAN2000. Each bus coupler is directly wired to a number of lamps, switches, or sensors. For example,bus couplers2030 and2040 are each dedicated to a lamp group,bus coupler2020 receives signals from a number of switches, andbus couple2010 receives inputs from sensors (e.g., motion and sun detectors). The bus couplers can be mounted in an electrical distribution box with the loads and inputs connected through a conventional mains cable.
• The[0214]lighting system LAN2000 can be implemented using an EIB or other LAN. The EIB LAN uses a bus converter to connect the LAN to thecontrol server100 using an available RS-232 port of thecontrol server100. The lighting network can operate even if thecontrol server100 has a failure. However, interaction with other systems, such as central locking or security, would not be available. A networked lighting system offers flexibility that allows the relationship between switch and lamp be changed simply by re-configuring the system. In addition, lamps, switches, and sensors attached to thelighting LAN2000 can be shared and controlled by other systems connected to thecontrol server100. For example, the central locking system can put the house into standby mode when closed ensuring that no lights are left on when the house is empty. A light sensor can be used to detect sun rise and sun set so that thecontrol server100 can control the lights in a way to simulate occupation. Optionally, motion sensors can be used to switch lights off when a room is unoccupied or to switch them on when someone enters.
• The lights also can be controlled using any of the BC system interfaces, such as, for example,[0215]PC190,portable tablet150 or through a remote interface connected throughInternet portal5.
• Temperature Control System[0216]
• A temperature control system is shown in FIG. 21. A heating LAN (e.g., an EIB LAN) can be used to control the temperature of rooms and provide zone control. The heating LAN connects the[0217]control server100 to control valves, to room thermostats, and to room displays through a number of bus connectors. Alternatively, the heating LAN can be controlled by auniversal controller110 or azone control133 under supervision of the control server100 (as described in the next section). As shown in FIG. 21, thecontrol server10 communicates with room thermostats through the heating LAN while bus couplers drive on/off valves, proportional valves, and dampers. Alternatively, RF controlled dampers and thermostats can be used as described above with regard to FIGS.9-11.
• Linking the heating LAN to the[0218]control server100 gives access to the other systems so that, for example, the central locking system could put the heating system into standby mode when the house is locked. The window sensors used either by a central locking system or a security system can be used by the heating system to turn off room radiators when a window in the corresponding room is open for longer than a certain period of time.
• A network of thermostats and valves allows a comprehensive software user interface offered by the home manager to effectuate zone and profile control.[0219]
• Zone and Profile Temperature Control System[0220]
• The[0221]universal controller110 offers a very flexible temperature control system that can be linked to thecontrol server100. An LCD touch-pad112 gives the user access to the system for changing temperatures, times, and other system management functions. Theuniversal controller110 is designed for mounting in an electrical distribution box. The box can be placed adjacent to thecontrol server100 or close to the valve/damper array for the heating system. Theuniversal controller110 links to thecontrol server100 using an RS-485 network interface.
• The control panel[0222]112 is wall mounted and connects to the universal controller through three sets of twisted-pair wires. Eachuniversal controller110 has up to 16 configurable analogue/digital inputs and twelve configurable relays output pairs. To add additional inputs and outputs a seconduniversal controller110 can be networked into the system. Up to three control panels can be placed at different positions around the home. An additional power supply allows two more control panels to be added if desired.
• Once installed, the[0223]universal controller110 needs to be configured. Configuration should be carried out by trained personnel using a PC running configuration software. The temperature control system allows up to 16 zones for either heating or cooling systems or 10 zones for combined heating and cooling. For example, each room in the house could be configured as a single zone. A temperature sensor in each room allows the user to set the required temperature and control the temperature controlling a valve/register to the room radiator feed or air damper. For combined heating and cooling systems, a valve is added to control the fan coil feed.
• Each zone is programmed with a profile of temperatures by day of the week and time of day. As a result, only those rooms, which are normally occupied at particular times or days need be heated or cooled. The control panel[0224]112 allows the user to over-ride these profiles at a given time. The profiles can also be over-ridden by thecontrol server100 so that, for example, the heating system can be turned down if the central locking system reports that the house is locked and unoccupied. An outside air temperature sensor can be added to allow improved temperature control algorithms that account for ambient weather and temperature conditions.
• The[0225]universal controller110 can interface directly with a fire alarm system or individual smoke detectors allowing the universal controller to close all dampers and turn of the boiler and air circulating fan upon detection of a fire.
• A wide variety of other sensors can be added to complement the functions offered by the system. For example, CO, CO2, flammable gas sensors could also be incorporated for home safety.[0226]
• The[0227]universal controller110 has a monitor function that allows current status of all connected devices to be viewed. The monitor function can be made available to thecontrol server100 and to any user interface (e.g.,150 or190) connected to thecontrol server100, including a telephone connection. The home manager software can deliver a Java file that is displayed using browser software on alocal PC190, or over a remote connection usingInternet portal5. An example of a screen shot for control of the HVAC is shown in FIG. 23.
• Networked Appliances[0228]
• An appliance network is shown in FIG. 24. The networked appliances can communicate with the[0229]control server100 usingPLC LAN3. An appliance is networked simply by plugging the appliance into the wall outlet connecting the appliance to thecontrol server100 through the PLC network. As a result, no additional wiring or re-configuring is necessary each time an appliance is installed or reconfigured.
• Connecting appliances to the[0230]control server100 provides a number of benefits due to the sharing of data with other networked devices and the connection to external service monitoring companies through a phone line or Internet connection.
• The home manager software is able to display virtual control panels for each appliance as shown in FIG. 25. As a result, the appliance can be controlled remotely under the supervision and monitoring of a[0231]portable web pad150 within the home, or from a remote location using theInternet portal5. When combined with the AvCast option, the home manager pages can be displayed on the TV screens in the home. As a result, during advertisements, for example the user can switch to the oven channel to see how the roast is doing. The appliance's virtual control panel has the same appearance as the physical controls panel on the appliance.
• Service companies can offer remote monitoring facilities to reduce the cost of repairs enabling them to offer extended warranty coverage for all such connected appliances.[0232]
• Interactive Marketing[0233]
• According to another aspect of the BC system, users' actions may be monitored in order to provide better service to the users of the BC system. The BC system allows consumer and commercial marketing companies, for example, to understand what the users are doing in their homes at all times. An advantage of using the BC system to monitor consumer activity, is that the user is not required to fill out surveys, report data manually, or otherwise change patterns of daily behavior in order to permit the collection of data. In addition, the BC system allows diagnostic information to be gathered to improve operation of system components and build infrastructure systems within the premises.[0234]
• Through use of the control server, communication modules, and monitoring components, such as a smart module or retrofit plug, data can be sent using the Internet portal, to service provider for monitoring and analysis. Using the diagnostic components of the system, the monitoring company can monitor use of appliances, systems, and components within the home to determine exactly what activities are being performed by each appliance, including the exact time the appliances were used and the duration of the use. For example, a networked washer and dryer can be monitored by a service provider to determine what cycle the washer is in. When the cycle is finished the washer display or user interface, for example portable tablet can display a coupon for detergent, fabric softener, or anti-static dryer towels. If the appliance malfunctions, the control server can turn off the appliance before permanent harm is done and send a message to the user service provider that repair is required. In response, the service provider can supply instruction to the user for simple repairs that do not require a technician's assistance. In addition, merchants can monitor the appliance's usage in order to provide better warrantees that are based on the specific customer's actual usage.[0235]
• RF tags can be used to improve appliance performance. For example, RF tags can be included in clothing so that the appliance informs the user when clothes do not match the selected cycle. Coupons or and advertisement can be displayed for the type of clothes washed. For example, if delicates are being washed, a coupon for Woolite can be displayed. The advantage of the BC system over prior couponing systems is that the coupons can be displayed to the user when the user can take advantage of the coupon. Additionally, food RF tags can be monitored by control server to remind the user that certain food items are running low or are soon to expire or should be disposed of At the same time, coupons can be sent and displayed to user of those items. Alternatively, a shopping list can be automatically generated and sent to a shopping delivery service so that the user does not even have to order or shop for designated items.[0236]
• TV Channel Recorder[0237]
• Techniques may be used to map the time of programming watched to identify exactly what the television was tuned to at any particular time. Because of the ability to catalog time and tuning the data logged by the[0238]control server100, market researchers can determine what was being display based on the channel, location, and time. With this information, market researchers can precisely determined what information was displayed on the TV and determine specific viewing habits of a household. If personal RF tags, key fobs, or remote controls are also used then thecontrol server100 also can identify who was in the room when the TV was tuned to the channel and determine who was viewing a program or commercial.
• Furthermore, the action of the TV channel recorder can be combined with an Internet activity recorder designed to monitor web surfing habits and PC usage habits. These features allow performance of web usage monitors of a nature substantially the same as the well known TV usage monitoring services, such as, for example, ACNeilsen performs, but without intrusive use of logs or manual methods. It is even possible to link radio monitoring through a suitably adapted radio. The combination of TV monitoring, radio and/or PC usage monitoring, and in-home activity monitoring permits unsurpassed analysis of a household's economic activities. Prior to this, TV, PC, and home activity monitors were applied independently to various homes and statistical methods were used in an attempt to extrapolate the observed results to all homes of particular econometric groups.[0239]
• No holistic, whole household view was possible because of the intense intrusion that the manual log methods imposed on a given household. A complete 360° view of household activity is possible (with permission from the household) with the BC system. The integrated data from the BC system capture all of the media influences being presented in electronic form. As a result, more sophisticated statistical analysis of household response to the media influences presented is permitted. True cause and effect analysis of advertising effectiveness can be performed, which are far superior to current methods.[0240]
• In the final case, store point of sale data from participating local stores or RF tag data from tags attached to purchased goods or bar codes scanned from purchased goods can be used to close the loop on media influence measurement. Goods can be test marketed using various forms of promotion, including electronic and print media known to have been sent to a household, known to have been viewed, surfed or listened by particular household members engaged in known activities at known times and the resulting effectiveness measured with unparalleled accuracy without the distorted effect of requiring manual logs of activities to be kept by the household participants.[0241]
• Retrofit Refrigeration Monitoring Unit[0242]
• FIGS. 26A and 26B show a refrigeration monitoring system. As shown in FIG. 26A, a[0243]refrigeration appliance2600, such as, for example, a refrigerator or freezer, can be retrofit to monitor for food properties, such as, for example, spoilage, and to alert the operator of the refrigeration appliance so that appropriate action can be taken, if necessary.
• A[0244]refrigeration appliance2600 can be retrofitted for monitoring by adding a retrofit plug2650 (described above) to allow the appliance to communicate with a remotely located computer, such as, for example, acontrol server100, a gateway, or a building monitoring service. Theretrofit plug2650 includes an alternative power source, such as a battery, that allows the plug to operate in the event of a power failure or outage at the location of therefrigeration appliance2600. An LED indicator can be included on the outside of theretrofit plug2650 to indicate a battery low condition. Theretrofit plug2650 also can monitor the power level of the battery and signal a monitoring service or user when the battery should be changed.
• The[0245]refrigeration appliance2600 includes acompartment2610, such as, for example, a freezer or a refrigeration compartment. Asensor2620 can be included or retrofitted to therefrigeration appliance2600. Thesensor2620 can be retrofitted by drilling a hole in theappliance2600 to allow placement of thesensor2620, such as a thermistor or another temperature-sensing device, inside thecompartment2610. A special seal or ring (sized to the hole and including insulation characteristics) can be inserted in the hole to act as an anchor for thesensor2620. A cable orinterface connection2621 couples thesensor2620 to theretrofit plug2650. Theretrofit plug2650 includes a serial or other port to accept theinterface connection2621. Thesensor2620 provides data on the sensed condition within thecompartment2610, for example, temperature, to allow theretrofit plug2650 to monitor conditions within therefrigeration appliance2600.
• The[0246]retrofit plug2650 can process the sensed condition and perform analysis of the data. In one example, the plug can be programmed to calculate the speed at which temperature is rising in the appliance to determine how long it will be until food spoilage occurs. This information can then be provided to a user or monitoring service so that appropriate action can be taken. Alternatively, the sensed data can be sent to acontrol server100, a gateway, or a monitoring service to perform the analysis function. Temperature measurements can be taken in real time or at intervals designated by the user.
• The[0247]retrofit plug2650 can be installed by connecting theretrofit plug2650 to themain power supply2640 of theappliance controller2630. During normal operation, theretrofit plug2650 can use PLC communication to provide data about the refrigeration appliance. Alternatively, other communications interfaces can be used. Theretrofit plug2650 also may include a communications circuit implemented by a modem or a RF communication device. In the case of a modem, a phone jack and acommunications port2655 are provided as shown in FIG. 26B. In the event of a power failure, theretrofit plug2650 can alert a user or monitoring service that power is out. Theretrofit plug2650 also may dial a repair service if it is determined that there is a malfunction within therefrigeration appliance2600. The retrofit plug also monitors the temperature withincompartment2610 and can provide an estimation of how long until food spoilage occurs. The estimate can be updated if sensed conditions within thecompartment2610 change. Theretrofit plug2650 also can perform other analyses. For example, if it is determined that the compressor is on longer than expected, combined with a rising temperature in the compartment, the retrofit plug may determine that a door open condition has occurred and may provide a message to the user or monitoring service of the open door condition.
• Even if power is not lost, if the[0248]compartment2610 reaches a predetermined temperature, theretrofit plug2650 may perform certain actions. For example, theretrofit plug2650 may call using the modem, or transmit using the RF device, a monitoring service, the operator of the device, or a controller, such as a control server, to indicate that food spoilage is immanent or how long until spoilage will occur. Alternatively, a repair service can be contacted to fix the problem associated with the refrigeration appliance. The retrofit plug itself, as described above, can supply diagnostic data to aid in repair of the appliance, if necessary. In this way, food can be monitored and spoilage prevented to save an operator the cost of replacing the food. In addition, liability issues can be reduced by keeping records that although power was lost, or the refrigeration appliance malfunctioned, food temperature was maintained at an adequate level such that spoilage did not occur. Theretrofit plug2650 may simply provide the temperature or other power monitoring data to a control server, gateway, or monitoring service, which can perform analysis of the data and determine if any action is necessary. For example, if used in conjunction with thecontrol server100, a message can be displayed on a user interface that the freezer is not working, the door has been left open, or that a repair service should be called.
• As shown in FIG. 27A, in place of a retrofit a plug, a[0249]box2700 can attach to the outside of refrigeration appliance2600 (or the compartment2610). According to one implementation, theunit2700 can be implemented using a communications module (described above). In the implementation shown in FIG. 27A, a hole is cut and the unit withsensor2705 is inserted into the hole. A suitable seal is provided to ensure adequate refrigeration is maintained. Theunit2700 can use the seal to seat itself on therefrigeration appliance2600. Other means of fastening, such as, for example, adhesive, bolts, or screws also can be used. The seal may be inserted in the hole or be provided as part of theunit2700 andsensor2705.
• The[0250]unit2700 attaches to apower line2601 to provide power to all components of theunit2700. In addition, a back-uppower source2710, such as, for example, a battery is included to provide power in case of main power loss or outage. An external LED or some other indicator may be provided on theunit2700 to alert the operator of a low battery condition.
• A small processor or monitoring circuit[0251]2720 monitors temperature inside therefrigeration appliance2600. The monitor circuit2720 is connected with acommunications circuit2730. Thecommunications circuit2730 can be implemented using, for example, a wireless transceiver, a wireless transmitter, or a modem. Thecommunications circuit2730 can include a phone jack for connection to aphone line2735, if a modem is used. In the case of a temperature event, theunit2700 is programmed (by external device such as a key pad with an interface, through the modem, or by insertion of a memory chip, such as a flash memory) with a number to call to alert an operator or monitoring company of the temperature or condition within the appliance, indicating that food spoilage will occur without intervention. Alternatively, if a wireless communication device is used, a message could be sent to a gateway, a control server, or a communication link to alert a user or monitoring service of the temperature event. Themonitoring circuit2730 also can be programmed to perform all of the monitoring function and analysis that is provided by the retrofit plug or communications module.
• The[0252]sensor2705 andunit2700 also can be implemented as separate units connected by a cord orother interface2704 as shown in FIG. 27B. Theunit2700 can be mounted on therefrigeration appliance2600 using an adhesive or using a form of attachment, such as, for example, screws, bolts, or other means of fastening.
• A number of implementations have been described. Nevertheless, it will be understood that various modifications may be made. For example, advantageous results still could be achieved if steps of the disclosed techniques were performed in a different order and/or if components in the disclosed systems were combined in a different manner and/or replaced or supplemented by other components. Accordingly, other implementations are within the scope of the following claims.[0253]
