Claim 23:
24. A method, comprising:
determining a capacitance of a first capacitor and a capacitance of a second capacitor based on a first amount of a first electrode between a first pair of electrodes, wherein the first capacitor and the second capacitor are coupled together in parallel;
determining a capacitance of a third capacitor and a capacitance of a fourth capacitor based on a second amount of the first electrode between a second pair of electrodes orthogonal to the first pair of electrodes, wherein the third capacitor and the fourth capacitor are coupled together in parallel, and the first capacitor and second capacitor are coupled to the third and fourth capacitor in series;
determining a capacitance of a fifth capacitor and a capacitance of a sixth capacitor based on a third amount of the first electrode between a third pair of electrodes, wherein the third pair of electrodes is adjacent to the first pair of electrodes, wherein the fifth capacitor and the sixth capacitor are coupled together in parallel;
determining a capacitance of seventh capacitor and a capacitance of an eighth capacitor based on a fourth amount of the first electrode between a fourth pair of electrodes, wherein the fourth pair of electrodes is orthogonal to the third pair of electrodes and adjacent to the second pair of electrodes, wherein the seventh capacitor and the eighth capacitor are coupled together in parallel, wherein the fifth capacitor and the sixth capacitor are coupled to the seventh capacitor and the eighth capacitor in series, wherein the first pair, the second pair, the third pair, and the fourth pair of electrodes define an pathway; and
determining a position of the first electrode along the pathway based on the capacitances of the first, second, third, fourth, fifth, sixth, seventh, and eighth capacitors, wherein each capacitor of the first, second, third, fourth, fifth, sixth, seventh, and eighth capacitors is coupled to each other capacitor of the first, second, third, fourth, fifth, sixth, seventh, and eighth capacitors.
