Abstract
A heater system for resisting fog and ice buildup on advanced driver assistance cameras provides a chamber covering the camera lens and providing a transparent window through which the camera lens may be directed. A heating element communicates with an air gap between the lens and the transparent window and the periphery of the transparent window to provide heating of the transparent window without blocking an image received by the camera lens.
