Abstract

An electrical heating device comprises a substrate, a pair of parallel, spaced apart elongated conductors extending longitudinally of the substrate, and a semi-conductor pattern carried on the substrate and electrically connected to and extending between the conductors. The semi-conductor pattern produces a thermal image for an infrared target. In some embodiments, the thermal image is irregular or circular in shape and the semi-conductor pattern includes a plurality of transversely-spaced bars having relatively wide portions outside, and relatively thin portions within, the area producing the thermal image.
