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 method includes receiving one or more sense signals from a touch sensor of a device, comparing a value associated with the one or more sense signals to a first threshold, and determining, based on comparing the value to the first threshold, whether an object has come within a pre-determined proximity of a first pre-determined location at a surface of the device. The method further includes comparing the value associated with the one or more sense signals to a second threshold and determining, based on comparing the value to the second threshold, whether the object has come within a pre-determined proximity of a second pre-determined location at the surface of the device.

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 one embodiment, a method for determining the location of a touch on a touch sensor includes receiving input signals in response to a touch proximate to a location on the touch sensor. Each input signal may have a total capacitance that includes a first capacitance associated with the touch and a second capacitance that is parasitic capacitance. The parasitic capacitance of one or more of the input signals may be adjusted to result in the second capacitance of each of the input signals being substantially equal. An average capacitance of the adjusted input signals may be calculated. The location of the touch on the touch sensor may then be determined based on a comparison of the total capacitance of each of the input signals and the average capacitance of the input signals.

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, a method includes outputting a first current associated with a first electrode track of a self-capacitance touch sensor. The method also includes outputting a second current associated with a second electrode track of the self-capacitance touch sensor. The method also includes measuring a voltage associated with a difference between the first and second currents and determining a position of an object relative to the self-capacitance touch sensor based on the voltage.

Abstract: An apparatus includes a display stack and a controller. The display stack includes a display and a ground layer. The ground layer includes a plurality of columns. Each column of the plurality of columns includes a plurality of nodes. The controller provides voltages to a first plurality of nodes of a first column of the plurality of columns of the ground layer such that a sum of the voltages of the first plurality of nodes of the first column is less than or equal to two millivolts. The controller also measures values at a second plurality of nodes of a second column of the plurality of columns. The values at the second plurality of nodes indicates an amount of charge transferred from the first plurality of nodes to the second plurality of nodes.
