Abstract
An electronic signal and alarm protection proximity device is disclosed which may be strapped by a band assembly to a person's appendage or a permanent part of a piece of equipment. The instant invention transmits a signature encoded RF signal distinguishable from others to be monitored by an appropriate receiving station. When the device is taken out of range of the station or the band is severed the design is such that the signal at the receiving station is no longer received and an indication is thus had that the person or the equipment to which the device is or was secured may be leaving the allowed range of proximity and thus a search or other measures may be immediately initiated.
