Abstract

A thermal signature device according to this invention enables a firefighter to be located with a thermal imaging camera. The device includes an infrared emitting element having a predetermined frequency. The emitting element is situated in a housing that may be temporarily fastened to a firefighter'"'"'s clothing and manually actuated by the firefighter with a pushbutton to emit infrared signals that may be identified by an infrared camera. The thermal signature device may include a receiver in data communication with the emitting-element such that the emitter may be actuated by a remote transmitter. The housing may include a permanent fastener such as adhesive such that the firefighter may selectively attach the housing to a stationary object, such as a wall, where it may be more visible or to another person in distress. A location determining system utilizing the thermal signature device provides an infrared camera for detecting the emitter-element.
