Abstract

An identification system for identifying individuals within a facility and having a plurality of individual tags T to be carried on the person, each tag continuously emitting tag pulse rates unique to that tag at a predetermined frequency, at least one location detector unit placed at a monitor location, and having a signal processor unit 4, an antenna 1 to receive tag signals and a direction sensor 2 to generate a direction signal responsive to movement of an individual, so that the signal processor unit 4 will examine a tag signal only when a direction signal has been received from the direction sensor 2 and, a central processing unit 7 to communicate with each signal processing unit 4, and a method of detecting individuals in such a facility using such tags T and location detector units U.
