Abstract

A system for luggage self-tracking/identification during air travel involves a programmable, wireless LAN active transceiver preferably located inside each piece of luggage, with controlled access to the airlines'"'"' luggage tracking networks. Prior to a flight, each transceiver is loaded with the passenger'"'"'s itinerary, and logged in the airline'"'"'s network at check-in. Each transceiver is uniquely identifiable by the luggage tracking network. An example of a preferred identifier would be the utilization of its Medium Access Control (MAC) and its alphanumeric serial keyword to provide unique and secure registration/identification of the transceiver in the airline'"'"'s network. During the trip, which may include different stopovers before reaching the final destination, the transceiver is able to automatically compare its programmed itinerary with its current location via wireless access to the airports and aircraft wireless LANs. In this way, the transceiver is able to notify airline personnel if there is a disagreement between its programmed itinerary and its current location, thus preventing misrouting. The transceiver'"'"'s itinerary can be wirelessly re-programmed by airline personnel/network to account for flight changes or delays. Finally, the transceiver has an internal timer that starts counting down from the expected “total traveling time”, accounting for flight changes or delays. If this timer elapses without the itinerary being complete, the transceiver connects to a wireless access point (hotspot) to report itself as a missing luggage, avoiding a worldwide tracking initiative and speeding up recovery time.

Claims

1. An automated system for self-tracking and identification of assets during air travel comprising:

wireless access points located at airports, railway stations, seaports, or any place where a check-in for air travel can take place, and aircraft; and

airports and aircraft wireless Local Area Networks (LAN); and

the airlines'"'"' flight and luggage tracking databases; and

wireless LAN transceivers which are physically associated to each asset to be tracked.

2. A system according to claim 1, wherein each wireless LAN transceiver possesses the memory capabilities of storing information such as, but not limited to, the name and address of the owner, the trip itinerary, asset description information, asset handling requirements, and destination information.

3. A system according to claim 2, wherein each wireless LAN transceiver has a unique identifier for secure registration and identification in the airline'"'"'s luggage tracking database.

4. A system according to claim 3, wherein the unique identifier is implemented by the MAC address of the wireless LAN transceiver and an alphanumeric serial keyword which together implement a user-password registration and access scheme.

5. A system according to claim 2, wherein the unique identifier is provided by a magnetic card that comes with each transceiver.

6. A system according to claim 2, wherein all information to be stored is wirelessly uploaded onto the transceiver by means of a personal computer, a PDA, a cell phone, or other technical device.

7. A system according to claim 2, wherein all information to be stored is uploaded onto the transceiver by means of a wired connection to a personal computer, a PDA, a cell phone, or other technical device.

8. A system according to claim 2, wherein all information to be stored is manually uploaded onto the transceiver by using an alternative interface.

9. A system according to claim 2, wherein the trip itinerary is uploaded onto the transceiver by performing an automatic download from the airline'"'"'s web page using the passenger'"'"'s frequent flyer number.

10. A system according to claim 3, wherein the trip itinerary is wirelessly uploaded onto the transceiver at airport check-in during secure registration with the airline'"'"'s luggage tracking database.

11. A system according to claim 3, wherein each transceiver utilizes any of the IEEE 802.11 standards for wireless communication with the wireless access points at airports and aircraft.

12. A system according to claim 11, wherein each transceiver connects to the wireless access points at airports and aircraft by means of Open System Authentication.

13. A system according to claim 12, wherein each transceiver'"'"'s communication protocol is either HTTP or HTTPS.

14. A system according to claim 3, wherein each transceiver has at least one processor and control software for execution by the processor, wherein the control software includes instructions which cause the processor of each registered transceiver to receive flight information from a wireless access point by means of its wireless interface.

15. A system according to claim 14, wherein each transceiver connects to the wireless access point with the strongest radio signal when more than one of the latter is present.

16. A system according to claim 15, wherein each transceiver has the capability to update its stored itinerary after receiving new flight information, either by means of a Unicast or a Multicast connection.

17. A system according to claim 16, wherein each transceiver compares the flight information received with its stored itinerary and generates an alarm condition if the flight information does not match the stored trip itinerary.

18. A system according to claim 17, wherein the control software of each transceiver possesses at least two timers that are initiated and updated from the stored trip itinerary. The first timer allows each transceiver to compare its value to information in the stored trip itinerary indicative of a time when the transceiver ought to be on an aircraft. The second timer allows each transceiver to keep track of the total time elapsed since the start of the stored trip itinerary.

19. A system according to claim 18, wherein an alarm condition is also generated if any of the timers elapses.

20. A system according to claim 19, wherein each transceiver reports its alarm condition to airline personnel or the airline'"'"'s luggage tracking database immediately following the generation of the alarm condition.

21. A system according to claim 15, wherein airline personnel can request the transceiver to beep for identification or determine its position by signal-strength measurements from at least two nearby wireless access points.

22. A system according to claim 14, wherein each transceiver can be instructed to enter “

sleep mode”

while connected to a wireless access point.

23. A system according to claim 22, wherein communication to and from a transceiver in sleep mode is controlled at all times by the wireless access points at airports and in aircraft hence complying with air travel regulations pertaining on-board electronic devices.

24. A system according to claim 3, wherein the owner of a transceiver can check its whereabouts by connecting to the airline'"'"'s luggage tracking database via the Internet.

25. A system according to claim 3, wherein the owner of a transceiver can be notified by e-mail, SMS message or any other type of technical communication of the asset'"'"'s whereabouts.

26. A system according to claim 24, wherein the owner of a transceiver can initiate tracking initiatives if his or her asset is misdirected during the trip.

27. A system according to claim 1, wherein each wireless LAN transceiver can be powered using any type of battery.

28. A system according to claim 1, wherein each wireless LAN transceiver includes at least one antenna for transmission and one for reception, being possible to use the same antenna for both operations.
