Abstract:
1. A method, comprising: encoding a first number of bits with a sensor including several sensor tracks and an electrode, the first bits each corresponding to a different one of the tracks; applying a first voltage waveform to a first electrode segment of a designated one of the tracks and a second voltage waveform to a second electrode segment of the designated one of the tracks, the first segment and a second segment being spaced apart from one another by an electrically nonconductive gap; capacitively coupling the electrode to the first segment to provide a first signal in response to the first waveform and to the second segment to provide a second signal in response to the second waveform; and determining a second number of bits as a function of the first signal and the second signal with the sensor, the first bits and the second bits representing sensed position with the first bits being more significant than the second bits.
