Abstract
An ordnance usable against a living body, the ordnance having a tracking module with a transmitter that can use at least a portion of the body as an antenna. In preferred embodiments, the tracking module is releasably coupled to a carrier, and a pointed tip is disposed on at least one of the tracking module and the carrier. The module preferably includes a circuit that provides location information to the transmitter, and optionally provides additional information, including at least one of motion, compass, pressure, oxygen, and heart beat information. Transmission can occur at any suitable interval, including for example, at least three times during a ten minute period. The transmitter can optionally transmit a no heart beat signal, failure signal, and/or low battery signal. Preferred systems include a receiver that can send an interrogation signal, and the ordnance can include an interrogation receiving circuit for receiving interrogation signals.
