ABSTRACT:
An anti-removal monitoring device which may be strapped to a person's appendage or to a piece of equipment. Once activated, the device transmits a signature encoded RF signal distinguishable from others to be monitored by a receiving station. If either the person or the device moves or is removed to a range out of signal reception, or if tampered with as by cutting the strap, such alteration of the normal signal is detected at the receiving station. The device comprises, in one embodiment, a transmitter housing for electrical connection to a base in a manner sealing the connection against the elements, and with a biased piston movably mounted within the base for operative connection with both ends of the strap and for activation of the transmitter only upon completed securement of the strap ends about the appendage or equipment and into the base. In a second embodiment, the device comprises a transmitter housing for electrical connection to an intermediated base piece in a manner sealing the connection against the elements, and with a strap of which one end is mounted on the intermediate base and electrically connected to the transmitter through a switch, and with a locking base piece with a projection through a diaphragm for operative activation of an electrical switch for activation of the transmitter only upon completed securement of the strap ends about the appendage or equipment and between the intermediate base piece and the locking base piece, and for operative activation of another electrical switch for completing the tamper circuit from the strap to the transmitter.
