ABSTRACT:
One embodiment of the present invention comprises a sensor with a face having several tracks spaced apart from one another. One of these tracks has a first electrode and a second electrode separated by an electrically nonconductive gap. Also included is a detection device extending across the tracks to receive signals by capacitive coupling. Sensor circuitry electrically coupled to the tracks and the detection device is structured to generate a first number of bits from a sequential signal pattern applied to the tracks in accordance with an established sequence. The circuitry is also structured to generate a second number of bits as a function of a first signal and a second signal. The first bits and second bits represent a position of the detection device along the tracks with the first bits being more numerically significant than the second bits.
