Abstract
A method and necessary apparatus for detecting the unauthorized operation or asportation of mobile or portable equipment. The apparatus comprises a concealable transmitter designed to re-transmit a coded message received from a check station. The check station may be stationary such as at the exit gate of a garage or at a fixed checkpoint along a thoroughfare; or may be carried on a vehicle such as a police car or other type of security patrol. The concealed repeating transmitter is switched on or off by means of a pocket-sized short-range coded remote switch unit not unlike those used for the remote control of household television receivers.
