Abstract
A heated mirror has a heating element thermally bonded to the rear surface and a transparent conductive coating applied to its front surface and divided by a narrow gap into portion between which the capacitance and resistance will be influenced by moisture. Changes in resistance and/or capacitance of the coating are sensed and used to control the leaking element so as to apply heat to the microns when fogging occurs.
