connection with the engine of said vehicle and having means to
disable said engine, said controller having a means for propagating
a radio frequency interrogating signal on a periodic basis and
within a limited area; said area being defined in terms of the
distance from said controller; a second part comprising: a radio
frequency transmitting and receiving device for sending out a ratio
frequency response signal in response to said interrogating signal
and of size suitable for concealment on a human; said controller
having a means for receiving said response signal and for
determining whether said response is an authorized signal, said
controller having a means for disabling said engine in the event
