Abstract:
A body worn personal monitor comprising:a case containing an rf transmitter;a battery for powering said transmitter and a control for periodically causing a coded signal to be transmitted by said transmitter;an elongated flexible band connected at either end to said case to enable encircling of a body member to allow wearing of said case by a person to be monitored;an electrically conductive element extending within said band and electrically connected at each end thereof to an electronic detector in said case;a connector for detachably connecting one end of said band to said casing including an electrical terminal for establishing an electrical connection between said conductive element and said detector in said casing;said detector sensing and storing said resistance value of a circuit including said conductive element when said band is installed, and means causing ceasing transmission of said coded signal if a different resistance value is sensed, whereby if said band is cut and said circuit completed by another conductor, the difference in resistance will cause a cessation of rf signal transmission.
