Patent ID: 8624609

Claim:
A sensor comprising: a substrate; a plurality of drive electrodes provided on the substrate; plurality of sense electrodes provided on the substrate, each of the sense electrodes being capacitively coupled with at least one of the drive electrodes; and a controller, comprising at least one drive unit and at least one sense unit, the controller configured to apply a drive signal to each of the drive electrodes and to sense signals received from the sense electrode, wherein: each of the plurality of sense electrodes is formed of at least three elements that cooperate to form a respective sense electrode; the at least three elements that cooperate to form a respective sense electrode each comprise a group of one or more element portions that form first, second, and third groups of elements; and a portion of the first and second groups of elements co-extend in a first direction over a first area of the substrate and the second and third groups of elements co-extend in the first direction over a second area of the substrate.
