摘要： Systems and methods for determining a touch input are provided. The systems and methods generally include measuring the peak voltage at an electrode over a measurement period and determining a touch input based on the peak voltage. The systems and methods can conserve computing resources by deferring digital signal processing until after a peak electrode capacitance has been sampled. The systems and methods are suitable for capacitive sensors using self-capacitance and capacitive sensors using mutual capacitance. The systems and methods are also suitable for capacitive buttons, track pads, and touch screens, among other implementations.

摘要： An apparatus for inductive sensing or capacitive sensing is described. The apparatus may include a signal generator to output on a first terminal a first signal in a first mode and a second signal in a second mode. The apparatus may include a charge measuring circuit to receive on a second terminal a third signal in the first mode and a fourth signal in the second mode.

摘要： A capacitive sensor includes a switching capacitor circuit, a comparator, and a charge dissipation circuit. The switching capacitor circuit reciprocally couples a sensing capacitor in series with a modulation capacitor during a first switching phase and discharges the sensing capacitor during a second switching phase. The comparator is coupled to compare a voltage potential on the modulation capacitor to a reference and to generate a modulation signal in response. The charge dissipation circuit is coupled to the modulation capacitor to selectively discharge the modulation capacitor in response to the modulation signal.

摘要： A light-emitting touch button can include a first printed circuit board (PCB), a second PCB, and a pin coupling the first PCB to the second PCB. The first PCB can include first electronics to detect a touch event on a touch surface. The second PCB can include second electronics to control light emission. The pin can communicate the detected touch event from the first electronics to the second electronics. The touch button can also include a housing including one or more walls defining one or more light-emitting regions. One or more light sources can be disposed within the one or more light-emitting regions. The second electronics can control light emitted from the one or more light sources based at least in part on the detected touch event. The one or more walls can collimate the light emitted from the one or more light sources to the touch surface.

摘要： A conductive sheet, method for using conductive sheet and touch panel, having a base substance and conductive parts formed on one of the principal surfaces of the base substance. The conductive parts respectively extend in primary directions, and have two or more conductive patterns made from metal wires arranged in a second direction that is perpendicular to the first direction. The conductive pattern is constituted by serially connecting two or more large gratings in the first direction, and each of the large gratings is constituted by combining two or more small gratings. Around the edges of the large grating, non-connective patterns are formed from metal wires which are not connected with the large gratings.

摘要： A touch panel including a substrate, first electrodes, second electrodes, first wires, second wires and a means for shortening a gap between the second electrodes in a third direction is provided. The first electrodes are arranged sequentially in a first direction. Each first electrode has openings arranged in a second direction intersecting the first direction. The second electrodes are located in the openings. Each first electrode and the second electrodes surrounded by the first electrode constitute a sensing unit. The first wires and the second wires connect the first electrodes and the second electrodes to a driving circuit. The means for shortening the gap between the second electrodes in the third direction renders a ratio of the gap between the second electrodes in the third direction to that in the second direction to be smaller than 1:3.4, where the third direction intersects either the first direction or the second direction.
