Abstract

A sensor (100) includes a face (112) having several tracks (120) spaced apart from one another. One of these tracks (120) has a first electrode (134) and a second electrode (136) separated by an electrically nonconductive gap (132). Also included is a detection device (114) extending across the tracks to receive signals by capacitive coupling. Sensor circuitry (110) electrically coupled to the tracks (120) and the detection device (114) is structured to generate a first number of bits from a sequential signal pattern applied to the tracks (120) in accordance with an established sequence. The circuitry (110) is also structured to generate a second number of bits in response to a signal pattern from the detection device (114). The first and second bits represent detection device (114) position along tracks the (120) with the first bits being more numerically significant than the second bits.
