Heating apparatus with multiple element array
First Claim
1. A heating apparatus assembly for heating a surface, said assembly comprising a substrate with a multiplicity of heating elements arranged in an array of heating elements disposed upon at least one surface of the substrate, the heating elements comprising a coating of a thermally-sprayed resistive material over a dielectric material disposed between the coating and the surface of the substrate, the dielectric material comprising mica, each element being individually and independently controllable separate from other elements within the multiplicity of heating elements, wherein a voltage provided to each element, independent of a voltage provided to other elements is controllable, and such that a temperature of each element is individually controllable independent of a temperature of other elements.
