Abstract

A system and a sensor usable for the automated activation of a defrosting mechanism; particularly the automated defrost of a vehicle window. Further, the sensor is adapted for the detection and measurement of changes in the dielectric constant of a dielectric disposed on a surface. Further still, the sensor is adapted for detecting changes in the phase changes of water, i.e. detecting if and when liquid water becomes frozen into frost, ice or snow. The sensor is coupled to a processor and various defrosting means for automatically defrosting vehicle windows in response to a remote signal, such as that provided by a keyless entry or remote starter.
