First Claim
Patent Images
1. An automotive mirror assembly comprising:
- a mirror;
a transparent substrate proximate to the mirror;
a patterned coating on the transparent substrate, the patterned coating defining at least a portion of a capacitive element; and
signal monitor in communication with the patterned coating, the signal monitor for monitoring capacitive changes in the patterned coating.

Abstract
An automotive mirror assembly includes a mirror and transparent substrate adjacent to the mirror. The patterned coating is attached to transparent substrate and defines at least part of capacitive element. A capacitance sensor is in communication with the patterned coating thereby allowing capacitance changes induced in the patterned coating to be monitored.
