CA 2131726

2131726 9318476 PCTABS00025 A tracking and identification system comprises a plurality of active badges carried by carriers, which may be humans and/or animals and/or objects within a predetermined area, together with a plurality of transceiver sensor stations within the area and in communication with a master control centre. Each badge has an IR transmitter (30) for transmitting a unique IR identification signal, and an astable oscillator (16) which, via a microprocessor (18), causes the IR identification signal to be spontaneously transmitted on a periodic basis, for example every 10 seconds. Additionally, by means of push buttons (14), the IR identification signal can be transmitted by a user prompt, and, by means of an RF field detector (12), the IR identification signal can be transmitted due to entry of the badge into the RF field of an RF field generator.
