Abstract: A rotatable device has a stationary base including bottom and top surfaces. The bottom surface has a first set of coupling electrodes configured to receive a reference signal from first electrodes of an attached input device, and second and third sets of coupling electrodes each configured to receive resulting signals from a second set of input device electrodes. The top surface of the stationary base has first, second and third top regions respectively connected to the first, second and third sets of coupling electrodes. The rotatable device further includes a rotary wheel, configured to rotate relative to the stationary base, with a bottom portion provided with alternating conductive and non-conductive regions and configured to align with the top portion of the stationary base. The resulting signals of the input device are modified by the relative positions of the stationary base and the rotary wheel.

Abstract: In a method of capacitive sensing, a first plurality of sensor electrodes of a sensor electrode pattern is coupled, in a first configuration, to input channels of a processing system. The sensor electrode pattern is associated with a sensing region. The first configuration of the first plurality sensor of electrodes is utilized to acquire a measurement of current. A noise environment is determined through analysis of the measurement of current. At least one subset of the first plurality of sensor electrodes is coupled, in a second configuration, to the input channels. The second configuration and the first configuration are different. The second configuration of the first plurality of sensor electrodes is utilized to acquire capacitive resulting signals.

Abstract: An input device is disclosed that provides reduced electromagnetic emissions while detecting the presence of an input object. In one embodiment, a first set of sensor electrodes is driven with a first modulated signal while a second set of sensor electrodes is driven with a second set of modulated signals that is based on an inverted first modulated signal. The first set of sensor electrodes may determine a capacitance value while the second set of sensor electrodes may reduce electromagnetic emissions associated with the first set of sensor electrodes.

Abstract: A method of operating a plurality of electrodes, and a related processing system and input device are disclosed. The method comprises driving, within a first time period, a plurality of sensor electrodes with a first signal. A first portion of the plurality of sensor electrodes defines a first sensing region within a first region, and a second portion of the plurality of sensor electrodes defines a first border region within the first region. The method further comprises driving a plurality of mitigation electrodes with a second, opposite polarity signal to mitigate electromagnetic emissions resulting from driving the plurality of sensor electrodes. The plurality of mitigation electrodes defines a second region adjacent to the first border region. The method further comprises acquiring, responsive to driving the plurality of sensor electrodes, first capacitive measurements with the first portion.

Abstract: A capacitive input device has a sensor electrode pattern disposed on a first side of a substrate. The sensor electrode pattern comprises a plurality of sensor electrode elements disposed on the first side of a first substrate. A plurality of routing traces is disposed along a first edge of the sensor electrode pattern on the first side of the substrate and configured to communicatively couple at least some of the sensor electrodes with a processing system. A pair of guard traces is disposed in the same layer as and brackets the plurality of routing traces. A guard overlaps the routing traces, is disposed proximate the routing traces on the first side of the substrate, and ohmically couples the pair of guard traces with one another. A second insulator is disposed between the routing traces and the guard. The second insulator and the first insulator are disposed in the same layer.
