Abstract: A method for capacitive sensing includes acquiring a mutual capacitive measurement including effects of sensing signals of a sensing region, and acquiring an absolute capacitive measurement including effects of the sensing signals. The method further includes performing a comparison of the mutual capacitive measurement and the absolute capacitive measurement, and detecting a presence of an input object proximate to a side surface of an input device based on the comparison. The side surface is at least substantially orthogonal to the sensing region on the input device. The method further includes reporting the presence of the input object.

Abstract: In a method of input object sensing, a plurality of transmitter electrodes are driven in a first way to acquire a first sub-frame image with the plurality of transmitter electrodes and a plurality of receiver electrodes of a sensor electrode pattern during a first sub-frame of a transcapacitive sensing frame. The plurality of transmitter electrodes is also driven in a second way to acquire a second sub-frame image with the plurality of transmitter electrodes and the plurality of receiver electrodes during a second sub-frame of the transcapacitive sensing frame, wherein the first way and the second way differ. A capacitive image is determined by combining the first sub-frame image with the second sub-frame image such that a motion artifact associated with an input object and present in at least one of the sub-frame images is suppressed by the combining.

Abstract: A capacitive sensing device has a first plurality of sensor electrodes, and a second plurality of sensor electrodes overlapping the first plurality of sensor electrodes. A first sensor electrode of the second plurality of electrodes overlaps a first subset of the first plurality of electrodes and comprises apertures disposed according to first codes. The first codes comprise first and second coefficients and along one of the first plurality of sensor electrodes. Each aperture may correspond to one of the first coefficients. The capacitive sensing device further comprises a processing system coupled to the first and second plurality of sensor electrodes. The processing system may be configured to receive resulting signals with the second plurality of sensor electrodes to determine positional information for an input object within a sensing region of the capacitive sensing device.

Abstract: Embodiments described herein include a method for detecting a presence of an input in a capacitive sensing device that includes a sensing region and a plurality of sensor electrodes. The method includes driving a first column of transmitter sensor electrodes at a first potential and driving a second column of transmitter sensor electrodes at a second potential different than the first potential. The method includes acquiring a measurement from each row of sensor electrodes, where a first sensing node includes the first column of transmitter sensor electrodes and a third column of receiver sensor electrodes, and a second sensing node includes the second column of transmitter sensor electrodes and a fourth column of receiver sensor electrodes. The method also includes determining, using the measurements from each row of sensor electrodes, a first set of transcapacitive measurements corresponding to the plurality of sensor electrodes.

Abstract: A method and apparatus for determining an eye gaze direction of a user through one or more non-contact capacitive sensors. For at least some embodiments, a differential capacitance associated with a users' eye may be determined through at least one of the non-contact capacitive sensors. The differential capacitance may be based on capacitance measurements associated with the users' eye performed at different times. The eye gaze direction may be based, at least in part, on the determined differential capacitance. For some embodiments, two or more non-contact capacitive sensors may be positioned along an axis. Differential capacitance measurements from the two or more non-contact capacitive sensors may determine the eye gaze direction with respect to the axis.
