1. ) A method for tracking the location of a piece of luggage, comprising:
- a) placing a navigational system beacon device (NSBD) in close proximity to the piece of luggage;
b) receiving a transmission of position information at a component of the NSBD;
c) storing position information at a component of the NSBD; and
d) transmitting a signal from the NSBD to report position information;
wherein the NSBD'"'"'s ability to transmit position information is toggled off under the control of an accelerometer when an aircraft containing the piece of luggage takes off and or the NSBD'"'"'s ability to transmit position information is toggled on under the control of the accelerometer during or after the landing of the aircraft, or wherein the toggling on or off of the NSBD'"'"'s transmission capacity is constrained by a history circuit comprising an accelerometer.

Abstract
The present invention provides a luggage finder that uses navigation system technology to locate baggage. A navigation system beacon device (NSBD) is stored in, on or near a luggage item, and is turned off and on respectively by an accelerometer during take-off and landing of aircraft, such that the transmitted reporting signal is disabled while the plane is in flight. A signal from the NSBD is transmitted to a central server, from which the location of the baggage is communicated to its owner by an email message or by a posting at a web site that can be accessed by the owner.

10. ) A method for tracking the location of a piece of luggage, comprising:
-
a) receiving a transmission of position information from a satellite or ground station at a component of a navigational system beacon device (NSBD) that is in close proximity to a piece of luggage; b) storing the position information at a component of the NSBD; c) optionally calculating the position of the luggage based on the position information received from the satellite or ground station, wherein the calculation is performed at a component of the NSBD; d) transmitting a signal from the NSBD to a central server to report position information, but wherein i) the NSBD'"'"'s ability to transmit position information is toggled off under the control of an accelerometer when an aircraft containing the piece of luggage takes off, ii) the NSBD'"'"'s ability to transmit position information is toggled on under the control of an accelerometer during or after the landing of the aircraft, and or iii) the toggling on or off of the NSBD'"'"'s transmission capacity is constrained by a history circuit comprising an accelerometer; e) calculating the position of the luggage at a component of the central server based on the position information received by the NSBD from the satellite or ground station, if the position of the luggage had not been calculated at a component of the NSBD; and f) transmitting position information from the central server to electronically to a client telephone, email address, handheld navigational device or client-accessible web page entry; wherein position information received at the NSBD is processed to determine the location of the luggage by means of a computation at the NSBD, the central server, the handheld navigational device, the client-accessible web page, or a combination thereof. - View Dependent Claims (11, 12)

13. ) A self-locating luggage unit, wherein the luggage unit comprises a piece of luggage in close proximity to a navigational system beacon device (NSBD), and wherein the NSBD comprises:
-
a) a component that can receive transmissions of position information; b) a component that can store position information; c) a component that can transmit position information; and d) one or more accelerometers under the control of which the NSBD'"'"'s transmission ability can be toggled off during take-off and toggled on during landing or after landing of an aircraft in which the luggage unit is located, or wherein the toggling on or off of the NSBD'"'"'s transmission capacity is constrained by a history circuit comprising said accelerometers. - View Dependent Claims (14, 15, 16, 17)

18. ) An integrated system for tracking the location of a piece of luggage, comprising:
-
a) the piece of luggage; b) a navigational system beacon device (NSBD) in close proximity to the piece of luggage, wherein the NSBD comprises i) a component that can receive transmissions of position information; ii) a component that can store position information; iii) a component that can transmit position information; and iv) an accelerometer under the control of which the NSBD'"'"'s transmission ability can be toggled off during take-off and toggled on during landing or after landing of an aircraft in which the luggage unit is located, or under the control of which the toggling on or off of the NSBD'"'"'s transmission capacity is constrained by a history circuit comprising said accelerometer; c) a central server that can receive position information from the NSBD'"'"'s transmissions and communicate position information to a client; and d) a means for sending position information electronically to the client from the central server, and or a web site accessible to the client wherein the web site is capable of receiving and displaying position information. - View Dependent Claims (19, 20, 21, 22, 23, 24)
