Abstract: In one embodiment, a selectively-releasable adhesive includes a copolymer formed from a multifunctional alcohol and a multifunctional carboxylic acid, wherein the copolymer has been cured the equivalent of up to approximately 20 hours at 120° C. and 100 millitorr.

Abstract: In one embodiment, a method for preparing a selectively releasable adhesive includes condensing a multifunctional alcohol and a multifunctional carboxylic acid to form a prepolymer and curing the prepolymer at an elevated temperature and a vacuum to produce a cured polymer.

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.
