Abstract
A device for accounting for environmental capacitances caused by an external object when detecting the presence and surface location of an electrically conductive coating on a transparent and/or translucent medium includes: a capacitive sensor that provides multiple capacitances; electronics that are responsive to the capacitances; an excitation source that generates a train of pulses, voltage or current to determine capacitances at the capacitive sensor; a selective indicator; and, a capacitive sensing plate that affects, or is affected by, the pulses, voltage or current from the excitation source.
