Abstract
A method of sensing absolute position of a structure includes: generating a signal pattern to repetitively provide a changing voltage to each of two or more tracks of a sensor, capacitively coupling an electrode of the sensor to the tracks to determine a first electrode position along the tracks by detecting a first group of signals emitted in response to the signal pattern, moving at least one of the electrode and the tracks relative to another of the electrode and the tracks to result in a second electrode position along the tracks different from the first electrode position, and detecting a second group of signals emitted in response to the signal pattern with the electrode capacitively coupled to the tracks to determine the second electrode position.
