ABSTRACT:
An imminent icing condition enunciator employs an infrared sensor with a focusing element to receive ambient infrared energy from a surface, particularly a road surface, and the output of the sensor is processed to provide an indication of imminent icing to the operator of, for example, an automobile or other vehicle. The device is suitably mounted to a vehicle, within a mirror enclosure so as to provide an unobstructed view of the roadway surface.
