Patent ID: 8525799

Claim:
An apparatus, comprising: a first set of sensor elements disposed in a first axis in a plane of a touch-sensor device; a second set of sensor elements and a third set of sensor elements disposed in a second axis in the plane, wherein the second set of sensor elements is disposed in a first section of the touch-sensor device and the third set of sensor elements is disposed in a second section of the touch-sensor device that is adjacent to the first section, wherein the first set, second set, and third set of sensor elements are configured to be separately scanned to detect a presence of one or more conductive objects on the touch-sensor device; and a processing device coupled to the first set, second set, and third set of sensor elements, wherein the processing device is configured to detect the presence of the one or more conductive objects on the touch-sensor device, and wherein the processing device is configured to resolve a plurality of locations of a plurality of substantially simultaneous touches on the touch-sensor device without an all-points-addressable array of sensor elements in the touch-sensor device.
