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.

Abstract: A fully implantable nerve stimulation system includes an event-triggered, closed-loop control unit that detects physiological events from nerve signals and delivers stimulation pulses to a nerve to produce a desired physiological response. The stimulation system includes a low-noise, low-power nerve signal amplifier, accelerometers that detect position and a battery powered processor that selectively powers components in the system to detect physiological events and deliver stimulation pulses with a minimum of battery power.
