    摘要: Touch panel systems and methods are disclosed that can distinguish temporally overlapping touch inputs from single touch inputs so that valid touch position coordinates can be determined. Touch panel systems and methods of the present invention can distinguish overlapping touches by comparing signal magnitudes to specified thresholds, by comparing the rates of change of signal magnitudes or measured positions to determined parameters, by locating the proximity a calculated location to icons or other such active areas, and the like. Because touch panel systems and methods of the present invention can discriminate single touches from double touches, they can be used in multiple user applications such as multiplayer games as well as in applications that may be subject to rapidly successive or overlapping touch inputs.

    摘要: Touch sensing systems and methods employ a touch surface and a touch sensor. An array of electrodes of the touch sensor is configured to capacitively couple to a touch in proximity with the touch surface. Circuitry is coupled to each electrode via a channel and configured to sense signals present on the electrodes. The circuitry is configured to independently adjust a sensed response of each electrode. For example, the circuitry may be configured to adjust a gain of each channel, an offset of each channel, or a gain and offset of each channel.
