Patent ID: 8860690

Claim:
A touch sensor having a first edge and a second edge approximately perpendicular to the first edge, the touch sensor comprising: a first plurality of electrodes approximately parallel to the first edge; a second plurality of electrodes, each of the second plurality of electrodes having a spine that is approximately parallel to the second edge and a plurality of conductive elements that are approximately parallel to the first edge and in physical contact with the spine, wherein at least one electrode of the second plurality of electrodes is adjacent to the second edge; and a plurality of nodes, each node formed by a capacitive coupling between an electrode of the first plurality of electrodes and an electrode of the second plurality of electrodes; and wherein the capacitance of each node is approximately the same; wherein the plurality of conductive elements of each of the second plurality of electrodes are each separated from each other by a gap; wherein one of the gaps of the one electrode of the second plurality of electrodes that is adjacent to the second edge has a width that is less than a width of at least one of the other gaps of the second plurality of electrodes.
