Patent ID: 7990160

Claim:
A method for determining capacitance, said method comprising: employing a set of sensor electrodes, said set of sensor electrodes comprising at least three sensor electrodes, wherein a first sensor electrode of said set of sensor electrodes meets a second sensor electrode of said set of sensor electrodes at a first activation region of a plurality of activation regions, wherein said first sensor electrode meets a third sensor electrode of said set of sensor electrodes at a second activation region of said plurality of activation regions, and wherein said second sensor electrode meets said third sensor electrode at a third activation region of said plurality of activation regions; transmitting with said third sensor electrode while receiving first indicia with said first and said second sensor electrodes; transmitting with said first sensor electrode while receiving second indicia with said second sensor electrode; and determining capacitances associated with said first, said second and said third activation regions using at least said first indicia and said second indicia.
