Abstract: An apparatus of one embodiment includes a sensor having a plurality of electrodes and a controller having a processor and a memory. The memory includes logic operable to configure the plurality of electrodes of the sensor to form a first cluster pattern including a first cluster and a second cluster. The first cluster and the second cluster each include two or more electrodes of the plurality of electrodes. The logic is further operable to determine a value associated with a capacitance of a first cluster and configure, in response to determining the value, the plurality of electrodes to form a second cluster pattern. The second cluster pattern includes a third cluster and a fourth cluster. The third cluster and the fourth cluster each include two or more electrodes of the plurality of electrodes and the third cluster is interleaved with the fourth cluster such that an electrode of the third cluster is positioned between two electrodes of the fourth cluster.

Abstract: In one embodiment, a touch-sensitive device includes a controller, horizontal electrodes, and vertical electrodes. The touch-sensitive device further includes a first plurality of switches that couple the horizontal electrodes to a first plurality of sensors, a second plurality of switches that couple the vertical electrodes to a second plurality of sensors, and a third and fourth plurality of switches that couple the horizontal and vertical electrodes to a shield sensor. The controller is operable to perform simultaneous hovering, touch, and proximity detection by selectively controlling, the first, second, third, and fourth plurality of switches. The hovering, touch, and proximity detection includes causing substantially equal voltages to be present on the horizontal and vertical electrodes while measuring capacitances using the shield sensor and either the first or second plurality of sensors.

Abstract: In one embodiment, an apparatus includes a sensor and a controller having a processor and a memory. The memory includes logic operable, when executed by the processor, to connect each electrode of a first subset of electrodes of the sensor and determine a first value associated with the first subset of electrodes. Based at least on the first value, the logic is further operable to alter the first subset of electrodes to a second subset of electrodes and connect, in response to determining to alter the first subset of electrodes to the second subset of electrodes, each electrode of the second subset of electrodes of the sensor.

Abstract: In an embodiment, a touch-sensitive device includes a controller, a shield sensor, a plurality of first electrodes, and a plurality of second electrodes. The plurality of first electrodes spans a first direction and the plurality of second electrodes spans a second direction that is different than the first direction. The controller electrically couples the plurality of first electrodes to the shield sensor. The shield sensor charges the plurality of first electrodes to cause substantially equal voltages to be present on the plurality of first electrodes and the plurality of second electrodes.
