Abstract: An electronic monitoring system includes an electronic monitoring device having straps for attaching the device to a limb of a subject for monitoring, at a remote location, movements and/or other activities of the subject; a closure member to be applied to the ends of the straps to secure them together according to the size of the subject's limb to be enclosed; and a manual resetting device having electrical terminals adapted to be brought into electrical communication with electrical terminals on the strap ends when the closure member is removed for resetting the electronic monitoring device.

Abstract: An electronic monitoring device to be attached to a subject for monitoring, at a remote location, movement and/or other activities of the subject, includes a closure member incorporating an identification tag having a unique identification number stored therein. The monitoring device further includes an electronic data processor programmed to read and store the identification number of the electronic tag when the closure member is applied, and periodically thereafter, to make a determination of whether a closure member is currently attached to the subject having an identification number matching the stored identification number, and to transmit to the remote location an identification signal corresponding to such determination.

Abstract: A tag for use with an electronic monitoring system for monitoring an object, which includes a housing enclosing electronic circuitry which includes a transmitter for transmitting a signal to a location remote from the tag, two straps connected to the housing and including an open electrical circuit, and a mechanism for mechanically and electrically connecting and locking the housing to a limb of the user which includes a base member and a cover member which, when forced together with the ends of the two straps between them, bring about an irreversible mechanical locking and simultaneously close the circuit running through the straps, preferably in a circuitous manner. In another embodiment, a secondary transmitter located in one of the straps transmits to a receiver located in the housing. Analysis of the received signals provides an indication of the proximity of the secondary transmitter to the object being monitored.
