REFERENCE TO PENDING APPLICATIONSThis application does not claim the benefit of pending application.
BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention is generally related to a loss prevention system, a specifically, toward a loss prevention system that includes providing an notification when an article is beyond a specific distance threshold.
2. Description of the Related ArtThere are several precious articles, such as mobile device, computer, camera, wallet, keys, important documents for example, that are carried on a daily basis and subject to loss either by theft or by being left behind by inadvertence.
For mobile devices, there exist applications that can be downloaded to communicate with an external device (such as the Tile device for example). The external device can be used to find the mobile device by making it ring. However, these devices will only effectively track the mobile device if the mobile device battery has some charge, furthermore, the system would not work if the mobile device is out of cellular or WIFI range.
The Tile system and other similar systems can also be attached to precious articles and the application on the mobile phone can be used to find the precious article using a geolocation detection. Again, these systems only work if the mobile phone is actively working (e.g. enough charge in the battery and/or within cellular or WIFI range).
The existing systems also are used to locate a precious article when it is already lost or stolen.
There is a need for a system that notifies a user that a precious article is moving away from them, before it is lost or while the thieves are still in reach without requiring an active mobile phone (e.g. charge in the battery and/or cellular or WIFI connectivity).
SUMMARY OF THE INVENTIONThis application discloses a system to protect from loss of one or more precious article owned by a user comprising a beacon device coupled with the precious articles, the beacon in short range wireless communication with a detection device coupled with the user, wherein the detection device periodically estimates the distance with the beacon device and triggers an alarm on the detection device when said distance exceeds a predetermined threshold.
The features of the invention which are believed to be novel are particularly pointed out in the specification. The present invention now will be described more fully hereinafter This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of illustration only and so that this disclosure will be thorough, complete and will fully convey the full scope of the invention to those skilled in the art.

DETAILED DESCRIPTIONFIG. 1 depicts the elements of the system. A user104 carries adetection device106 which is in wireless communication with abeacon device108 coupled to aprecious article102.
The precious article can be any article the user104 does not want to lose, such as, a mobile device, computer, camera, wallet, purse, keys, important documents, briefcase, for example.
Thebeacon device108 is a small device that can be attached to the precious article. The attachment can be done, for example, using strong double-sided tape.
Thedetection device106 is a small device that can be carried by the user104 either in a pocket, on a bracelet, a necklace, an armband, a chest strap, coupled to a belt, for example. Further, thedetection device106 may be attached to a second precious article. For example, abeacon device108 may be attached to wallet and adetection device106 may be attached to a user's keys.
Thebeacon device108 anddetection device106 are communicating using a wireless protocol and paired at manufacture. If at least one of the device is turned off or the battery is changed, an automatic pairing protocol between thebeacon device108 and thedetection device106 is activated to pair the two device using the wireless pairing standard used of the system without requiring user intervention.
In another embodiment, an application on a smart phone or tablet is used to pair the two devices. Once the pairing is done, the application is no longer used for the communication between the detection device and thebeacon device108. In another embodiment, the application can be used to program the parameters of the system.
Adetection device106 can be paired withmultiple beacon device108 to give a user104 the ability to protect multipleprecious article102.
FIG. 2 illustrates one embodiment of thebeacon device108. Thebeacon device108 is powered by abeacon battery204 which can be replaceable or rechargeable. Thebeacon battery204 can be of the type that can be charged using electrical, magnetic or solar charger as well known in the art. Thebeacon device108 comprises a beaconwireless communication208 module which comprises a beaconwireless receiver210 and a beaconwireless transmitter212. The beaconwireless communication208 module can be of any type of short range wireless protocol known in the art, such as bluetooth, RFID for examples.
Thebeacon device108 comprises abeacon processor206 to process the signals received by the beaconwireless receiver210 and to send signals via the beaconwireless transmitter212.
Thebeacon device108 may have a beacon on/offswitch214.
Optionally thebeacon device108 comprises abeacon alarm202 to emit sound and/or visual notifications when it is triggered by thebeacon processor206.
FIG. 3 illustrates one embodiment of thedetection device106. Thedetection device106 is powered by adetection battery304 which can be replaceable or rechargeable. Thedetection battery304 can be of the type that can be charged using electrical, magnetic or solar charger as well known in the art. Thedetection device106 comprises a detection wireless communication308 module which comprises a detectionwireless receiver310 and a detectionwireless transmitter312. The detection wireless communication308 module can be of any type of short-range wireless protocol known in the art, such as bluetooth, RFID for examples.
Thedetection device106 comprises adetection processor306 to process the signals received by the detectionwireless receiver310 and to send signals via the detectionwireless transmitter312. Thedetection processor306 periodically estimates the distance to thebeacon device108 and triggers adetection device alarm302 to emit sound when the distance to thebeacon device108 exceeds a predetermined threshold. The distance can be estimated at a regular predetermined interval of time. In another embodiment, the interval of time between estimation can be changed as a function of the distance to thebeacon device108 increases. For example, as thebeacon device108 moves further from thedetection device106, the interval of time is reduced. In another embodiment, the interval of time is reduced based on the variation in the estimated distance, such that if the beacon device is moving away faster, the interval of time is reduced faster to ensure the detection of the threshold being exceeded is done in a timely manner.
Thedetection device106 may have a detection on/offswitch314. The on/off switch may be any suitable type of switch, including a slide-type switch or a push-button type of switch. Thebeacon device108 may also have a similar type of switch.
FIG. 4 shows one embodiment of the system. In this embodiment, thebeacon processor206 on thebeacon device108 triggers the distance estimation. The beacon device sends a beacon signal todetection device402 via thebeacon wireless transmitter212. When the detection device receives signal frombeacon device404, the detection device estimates distance betweenbeacon device406, if the distance exceeds apredetermined threshold408, the detection device sounds thedetection alarm410. Optionally, thedetection device106 can send an alarm signal to thebeacon device108. When thebeacon device108 receive the alarm signal it triggers thebeacon alarm202.
The distance between thebeacon device108 and thedetection device106 can be estimated using any distance measurement algorithms known in the art, such as estimating the signal strength for example and estimating that the distance has increased when the signal strength is reduced.
Thebeacon processor206 can trigger the distance estimation at regular or variable intervals as disclosed above.
If the detection device does not receive beacon signal from the beacon for a predetermined period of time, it optionally triggers a different alarm sound to indicate loss of communication. Optionally, if the detection device receives a weakened beacon signal from the beacon for a predetermined period of time, it optionally triggers a different alarm sound to indicate a soon-to-be loss of communication. This option may be utilized to indicate that a battery is losing power.
In another embodiment, the estimation of the distance reflects a relative distance such as thebeacon device108 being further or closer than the previous estimation. The alarm is triggered, when the relative distance exceeds a threshold.
FIG. 5 shows another embodiment of the system. In this embodiment, the detection device sends trigger signal tobeacon device502 upon reception of the trigger signal, the beacon device sends a response signal to thedetection device504, the detection device estimates distance betweenbeacon device506 and if the distance exceeds apredetermined threshold508 the detection device soundsdetection alarm510. Optionally, the detection device sends alarm signal tobeacon device512 and the beacon device sounds beacon alarm upon reception ofalarm signal514.
In this embodiment, the distance can be estimated by having thedetection processor306 manage a timestamp and an associated unique identifier which is transmitted with the beacon signal. Thebeacon processor206 includes the unique identifier with the response signal. When thedetection processor306 receives the response signal, it computes a round trip delay between the timestamp associated with the unique identifier and the time the response signal is received. The round trip delay is then used as an estimation of the distance between thebeacon device108 and thedetection device106. A variation in the round trip delay can optionally be used as the distance estimation.
If the detection device does not receive a response signal from the beacon it optionally triggers a different alarm sound to indicate loss of communication.
Optionally, thedetection device106 can send an alarm signal to thebeacon device108. When thebeacon device108 receive the alarm signal it triggers thebeacon alarm202.
Thebeacon processor206 can trigger the distance estimation at regular or variable intervals as disclosed above.
Optionally further, when abeacon alarm202 and/or adetection device alarm302 has been triggered, a homing alarm feature may be engaged by thebeacon device108 and/ordetection device106. This feature will modify the alarm sound and/or visual alarm based on the distance between the two devices. For example, after an alarm has been triggered, as thedetection device106 is moved closer to thebeacon device108, the alarm sound may increase in volume and pitch. This modification may assist the user with locating the precious articles upon which the beacon device is attached in a more efficient and faster manner.
In some embodiments, thedetection device106 may include the functionality and capability of thebeacon device108, and thebeacon device108 may include the functionality and capability of thedetection device106. In these embodiments, thebeacon device108 and thedetection device106 may be simultaneously interchangeable.
In some embodiments, thepredetermined threshold408 may be selectable by the user. A selection slide or other similar component located on thedetection device106 andbeacon device108 may allow the user to select one of plurality of predetermined distances. For example, the user may set, or move, a selector switch located on the detection andbeacon devices106,108 in order to select a predetermined distance of 5 meters, 10 meters or 20 meters as the distance to be used as thepredetermined threshold408.
In some embodiments, when there are three or more devices linked together, the alarm signal may be sent to all linked devices so that adetection alarm410 and/orbeacon alarm202 may be triggered by all the linked devices. The alarms may be triggered for those linked devices that have not exceeded thepredetermined threshold408. For example, a first beacon device, a second beacon device and a detection device are linked. The first beacon device is moved beyond thepredetermined threshold408, while the second beacon device and the detection device remain within thepredetermined threshold408. An alarm signal may be sent to all three devices triggering an alarm from all three devices.
