The present invention relates to apparatuses for tracking items, and in particular, to apparatuses for tracking and locating bags and other personal items.
It is common for people to carry various personal items with them when travelling or otherwise away from home. For example, people may carry items such as handbags, purses, backpacks, briefcases, or the like with them. From time to time, those items may be misplaced or even stolen by unscrupulous thieves.
By way of example, air travel is a very common occurrence. During flight, the baggage of the passengers is typically stored separate from the passenger cabin. After landing, the passengers must retrieve their baggage, typically from a common baggage retrieval area in the airport. The baggage may be delivered to the common baggage retrieval area using conveyor belts, with the passengers manually picking up their baggage when they see it. This can cause confusion since the design and appearance of many baggage pieces look similar. In addition, depending on the number of passengers on the flight and/or the general level of activity at the airport, the common baggage retrieval area may be quite crowded, as the passengers jockey about to identify their baggage near the conveyor belts. It is therefore quite possible for a passenger to mistakenly take baggage belonging to another passenger.
There is therefore a need to improve the identification of one's baggage by passengers to reduce the likelihood of a passenger taking the wrong baggage. In addition, there is also a need to decrease the amount of overcrowding near the conveyor belts as the passengers' baggage is being delivered.
In accordance with one embodiment of the invention, a system for identifying passenger baggage comprises one or more locks and one or more communication devices. The lock may be built into the baggage or be a separate unit to lock the baggage. The communication device may be embodied as a separate unit or as a software application running on a smartphone, a tablet, a laptop computer, a smartwatch or the like. Both the lock and the receiver have the ability to receive wireless communications through cellular network, Wifi, Bluetooth and/or other technology.
Each of the locks has a unique identifier, which is captured by the communication device when in use. Once the lock is on the conveyor belt and within a preset distance from the receiver, a signal from the lock is picked up by the communication device. The communication device is configured to perform the following: (1) record the time when the signal is picked up (e.g. 50 feet or a pre-set distance from the lock; (2) a light on the lock will be turned on once the signal is received by the communication device; (3) upon receipt of the signal(s), the communication device will display all the identifiers of the locks that are within the pre-set distance; and (4) if the lock is moved out of the pre-set range, a flashing light on the lock will illuminate.
If a piece of baggage with the lock is mistakenly picked up by someone and moves out of the pre-set range, the identifier will no longer be displayed by the receiver. At that time, receiver may be configured to cause the light to flash, drawing attention of the person that has mistakenly taken the wrong baggage.
In one aspect of the invention, a method for tracking pieces of baggage comprises the steps of providing one or more first devices, each of the first devices being attached to the pieces of baggage and each of the first devices comprising a first transceiver; transmitting, by each of the first transceivers, wireless data, the wireless data comprising a device identifier for the respective first device; providing a second device, the second device comprising a second transceiver and a user interface; receiving, by the second transceiver, the wireless data from one or more of the first transceivers; displaying on the user interface the device identifiers corresponding to the respective first devices from which the wireless data was received; selecting one or more of the device identifiers, the selected one or more of the device identifiers corresponding to the first devices that are selected for tracking; and generating, by the second device, an alarm if one of the first devices that are selected for tracking moves beyond a particular distance from the second device, wherein the particular distance may be determined using a signal strength of the wireless data received by the second transceiver.

Referring to
The lock 102 further comprises a first transceiver 112 for sending and receiving wireless communications.
Each of the communication devices 104 comprises a second transceiver 114. The communication devices 104, using the second transceivers 114, may be able to communicate wirelessly with the locks 102, using the first transceivers 112. The first and second transceivers 112, 114 may be able to communicate wirelessly with each other through a wireless communication protocol, such as cellular network, Wi-Fi, Bluetooth, or the like.
In one embodiment, the communication devices 104 may be a mobile device 116, such as a smartphone, a tablet, a laptop computer, a smartwatch, etc., with a software application 126 configured to run on the mobile device 116. The software application 126 may be further configured to effect the operation of the second transceiver 114.
Each of the locks 102 is associated with a lock identifier 118 that is preferably unique to the particular lock 102. The lock identifier 118 may be an alphanumeric string or some other unique sequence. The lock identifier 118 may also be configured by the user beforehand so that it is more recognizable by the user. When the system 100 is in operation, each of the locks 102 will transmit one or more messages containing each of their corresponding unique lock identifiers 118 through the respective first transceivers 112. The communication devices 104, through their respective second transceivers 114, are configured to detect and receive wireless communications from any of the locks 102 that are within wireless communications range of their respective second transceivers 114.
Preferably, each of the communication devices 104 comprises a user interface 120 that is configured to display information to and/or receiving input from the user. For example, if one of the communication devices 104 receives communications from one or more of the locks 102, the communication device 104 may be configured to display on the user interface 120 the lock identifier(s) 118 of the lock(s) 102 within wireless communications range of the communication device 104. Alternatively, the communication device 104 may be configured to only display on the user interface 120 the lock identifier(s) 118 of the lock(s) 102 within a first pre-set distance of the communication device 104 (which is less than the wireless communications range of the communication device 104). For example, the first pre-set distance may be set by the user to be 50 feet or some other specified distance.
An approximate distance between the communication device 104 and the lock 102 from which the communication device 104 received communications may be determined by the communication device 104 using the signal strength of the communications received by the second transceiver 114 (e.g. using received signal strength indicator or RSSI to determine an approximate distance). If the lock identifiers 118 comprise alphanumeric strings, the lock identifier(s) 118 for the lock(s) 102 from which the communication device 104 received communications may be displayed on the user interface 120 as a list of alphanumeric strings, as shown in
The lock 102 may also comprise a light 132 located on an exterior of the lock 102 (e.g. an exterior surface of the lock 102). Preferably, the light 132 is configured to illuminate if one of the communication devices 104 is able to detect the lock identifier 118 of the lock 102. In this embodiment, if one of the communication devices 104 detects wireless communications from the lock 102, the communication device 104 is configured to transmit a signal (through the second transceiver 114) to the first transceiver 112 of the lock 102. Upon receipt of the signal by the first transceiver 112, the lock 102 is configured to cause the light 132 to illuminate, thus allowing for easier identification of the baggage 106 associated with the lock 102. In another embodiment, the communication device 104 may be configured to transmit the signal to the lock 102 only if the lock 102 is within the first pre-set distance of the communication device 104 (as determined, for example, using RSSI techniques).
Once the communication device 104 has received communications from the lock(s) 102 and has displayed the corresponding lock identifier(s) 118 on the user interface 120, the user may select to track one or more of the locks 102 displayed. The user may do so by selecting one or more of respective lock identifiers 118 on the user interrace 120. Once one or more of the lock identifiers 118 have been selected, the presence of their respective locks 102 may be tracked.
In one embodiment, the light 132 of the lock 102 is not illuminated by the lock 102 until after the respective lock identifier 118 for the lock 102 has been selected by the user. In this embodiment, once the user has selected the lock 102 on the user interface 120, the communication device 104 will transmit a signal (through the second transceiver 114) to the first transceiver 112 of the lock 102. Upon receipt of the signal by the first transceiver, the lock 102 is configured to cause the light 132 to illuminate. This will cause only the lock(s) 102 selected by the user (and presumably of interest to the user) to be illuminated, rather than all of the locks 102 within communications range of the communication device 104.
Referring to
Once the alarm 128 has been generated, the communication device 104 is configured to transmit the alarm 128 to the lock 102 to indicate that the lock 102 is out of the second pre-set distance. An approximate distance between the communication device 104 and the lock 102 may be determined by the communication device 104 using the signal strength of the communications received by the second transceiver 114 (e.g. using RSSI techniques). This may require that the lock 102 and the communication device 104 periodically exchange messages with each other in order for the communication device 104 to determine the approximate distance between the communication device 104 and the lock 102.
Alternatively, the lock 102 may be configured to also generate the alarm 128 itself if the first transceiver 112 detects that it is no longer in wireless communications with the communication device 104. This may also require that the lock 102 and the communication device 104 periodically exchange messages with each other to determine if they are still in wireless communications.
In either case, once the lock 102 is aware of the alarm 128 (whether received from the communication device 104 or generated by the lock 102 itself), the lock 102 is configured to cause the light 132 to alter its illumination condition (e.g. from being continually illuminated to now flashing intermittently), thereby alerting the person taking the baggage 106 that he or she may be taking someone else's baggage.
In one embodiment, once the lock 102 is aware of the alarm 128, the locking mechanism 108 will enter or remain in the locked configuration. The locking mechanism 108 will not enter the unlocked configuration until the alarm 128 is cancelled. This will prevent access to the baggage 106 until the alarm 128 is cancelled.
Upon generation of the alarm 128 by the communication device 104, the communication device 104 is configured to cause the user interface 120 to display an appropriate message to the user. The user interface 120 may be configured to allow the user to cancel the alarm 128. Upon cancellation of the alarm 128 by the user, the communication device 104 is configured to transmit an appropriate message to the lock 102 cancelling the alarm 128, assuming that the lock 102 is within communications range of the communication device 104.
In another embodiment, the lock 102 may also comprise a speaker 134. The lock 102 is configured cause the speaker 134 to emit noise (e.g. a siren) when the lock 102 is aware of the alarm 128. In addition, the lock 102 may be configured such that the speaker 134 plays pre-recorded sounds or messages when the lock 102 is aware of the alarm 128. For example, the user may record a voice message that would be played by the speaker 134. Alternatively, pre-recorded messages in different languages may be played by the speaker 134.
The user interface 120 may also be configured to no longer display the lock identifier(s) 118 of the lock(s) 102 once out of the first pre-set distance or, alternatively, out of wireless communications range of the communication device 104.
Although the lock 102 may be used to physically secure the contents of the baggage 106 (e.g. by attachment to the zipper 110), it is understood that the lock 102 may also take the form of a device that is attached to the baggage 106 but does not provide any physical securing of the contents. In such an embodiment, the lock 102 may simply be a tag, a name card holder, or some other similar attachment. In addition, the lock 102 may also take the form of a mobile phone or a smart device.
The lock 102 preferably comprises a power source 130 configured to provide electrical power to the components of the lock 102 (e.g. the first transceiver 112 and the light 132). The power source 130 may be a battery. In one embodiment, the lock 102 is configured to cause the light 132 to illuminate when the power source 130 is low on power. For example, the lock 102 may be configured to cause the light 132 to illuminate with a specific color (e.g. red) when the power source 130 is low on power.
In another embodiment, the lock 102 may further comprise a Global Positioning System (GPS) receiver 136 that is configured to determine location information of the lock 102. The location information may be transmitted to the communication device 104 in order to assist the user in locating the lock 102 (and the associated baggage 106).
The present invention may be employed in the following exemplary manner to track baggage, such as during travel. Prior to travel, the lock 102 is first attached by the user to the baggage 106 to be tracked. The lock identifier 118 for the lock 102 may also be set by the user. During travel, the baggage 106 may be separated from the user (such as during air travel when the baggage 106 is checked in). Once the user has arrived at the destination airport, the user can activate the communication device 104 in an area where the baggage 106 is expected to be picked up by the user (e.g. at baggage claim). The user may also set the first pre-set distance and/or the second pre-set distance using the communication device 104. The communication device 104 will attempt to receive messages from the lock 102. If the communication device 104 receives communications from the lock 102 (or from other ones of the locks 102), the communication device 104 will attempt to determine an approximate distance to each of the locks 102 from which the communication device 104 received communications. The communication device 104 will display on the user interface 120 a list of the lock identifiers 118 corresponding to the locks 102 that are within the first pre-set distance. The user may then select the lock 102 that he or she wishes to track (using the respective lock identifier 118). The communication device 104 transmits a signal to the lock 102 that was selected. The lock 102, upon receiving the signal, will cause the light 132 to illuminate. The user will thereby be alerted to the location of the baggage 106 and can then proceed to retrieve the baggage 106. In the event that someone else takes the baggage 106 and leaves with the baggage 106, once the lock 102 is outside of communications range to the communication device 104 (i.e. the communication device 104 is no longer able to receive communications from the lock 102) or the lock 102 is outside of the second pre-set distance, the alarm 128 will be generated. An appropriate message is displayed on the user interface 120. In addition, the light 132 on the lock 102 may be configured to flash and/or the speaker 134 on the lock 102 is configured to play an appropriate message (e.g. a siren or a pre-recorded message), alerting the person taking the baggage 106.
Referring to
The user may then select the lock 102 that he or she wishes to track by pressing the track button 138 corresponding to the lock identifier 118 for the lock 102. The communication device 104 transmits a signal to the lock 102 that was selected. The lock 102, upon receiving the signal, will cause the light 132 to illuminate. The user will thereby be alerted to the location of the baggage 106 and can then proceed to retrieve the baggage 106. In the event that someone else takes the baggage 106 and leaves with the baggage 106, once the lock 102 is outside of the second pre-set distance, the alarm 128 will be generated. This may cause the track button 138 corresponding to the lock identifier 118 for the lock 102 to flash. The user may press the alarm button 140 corresponding to the lock identifier 118 for the lock 102. This will cause the alarm 128 to be transmitted to the lock 102, which in turn will cause the light 132 on the lock 102 to flash and/or the speaker 134 on the lock 102 to play an appropriate message (e.g. a siren or a pre-recorded message), alerting the person taking the baggage 106.
If after a predetermined period of time (e.g. 10 minutes), the lock 102 is no longer outside of the second pre-set distance (e.g. it is back on the conveyor belt), the alarm 128 is deactivated, and the track button 138 may be configured to no longer flash. If after the predetermined period of time, the lock 102 is still outside of the second pre-set distance, the user may press the locate button 142 corresponding to the lock identifier 118 for the lock 102. This transmits a command from the communication device 104 to the lock 102 to activate the GPS receiver 136 on the lock 102. Location information from the GPS receiver 136 on the lock 102 may then be transmitted from the lock 102 to the communication device 104 for display on the user interface 120.
The communications between the communication device 104 and the lock(s) 102 may be through a number of wireless communications protocols, including, but not limited to, cellular network, RFID, Zigbee, Bluetooth, or Wi-Fi.
It will be appreciated by those skilled in the art that the preferred embodiments have been described in some detail but that certain modifications may be practiced without departing from the principles of the invention.
