Abstract

Abstract A system for monitoring the location of an individual is disclosed and includes a band to be strapped to the individual's wrist or ankle. A trigger, transmitter, and antenna are incorporated into the band. The trigger controls operation of the transmitter and activation is effected by a portable authority-retained control unit. The trigger deactivates the transmitter under predetermined conditions (such as removal of the band) and reactivation requires utilization of the control unit.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 136 words
A system for monitoring the movement of an individual comprising, in combination: portable control means for providing an activation signal; a band adapted to be secured to said individual including a band switch and an antenna wire, said band switch being operable whenever said band is secured to said individual; transmitter means for selectively providing a transmitter signal to be transmitted by said antenna wire throughout the vicinity of said individual as a detection signal, said band switch coupling said antenna wire to said transmitter means whenever said band switch is operable; trigger means, responsive to said portable control means and said band switch, for receiving said activation signal and responsively activating said transmitter means and for deactivating said transmitter means whenever said band switch becomes inoperable; and portable receiver means for receiving said detection signal.
