Abstract of Disclosure: In an automotive vehicle having a visual glass pane subject to collecting vision obscuring moisture in the form of ice frost, mist, fog, etc. apparatus is provided for removing the collected moisture. Specifically, the apparatus comprises a transparent layer of dielectric material underlying the glass pane in heat conducting relationship thereto, and means for producing dielectric heating of the dielectric material to thereby heat the glass and remove the collected moisture. Preferably, the layer of dielectric material is a polymer film and the means for producing dielectric heating includes a pair of transparent electrodes extending over the layer of dielectric …
