Abstract: A first capacitor and a second capacitor are charged until voltage at the second capacitor settles to a settling voltage. While charging, the first capacitor is alternately switched between a current source and ground. When the settling voltage is reached, charging of the first capacitor is halted. The second capacitor continues to be charged until voltage at the second capacitor reaches a reference voltage. The amount of time it takes for the settling voltage to reach the reference voltage corresponds to a measure of capacitance on the first capacitor.
Abstract translation: 第一电容器和第二电容器被充电直到第二电容器的电压稳定到稳定电压。 在充电时，第一电容器在电流源和地之间交替切换。 当达到稳定电压时，停止第一电容器的充电。 第二电容器继续充电，直到第二电容器的电压达到参考电压。 稳定电压达到参考电压所花费的时间对应于第一个电容器上的电容量度。

Abstract: An embodiment of the present invention is directed to a method for rejecting sensor information when a switch is being pressed in a system having sensors over switches. A switch in the process of being pressed may be determined based on an increase in pressure which may be determined by measuring the increase in capacitance at a plurality of capacitive sensors. The rejection of sensor information when the switch is being pressed allows the user interface to more accurately thus facilitates smooth and jitterless interface operation.
Abstract translation: 本发明的实施例涉及一种在具有开关传感器的系统中按压开关时拒绝传感器信息的方法。 可以基于可以通过测量多个电容式传感器的电容增加来确定的压力增加来确定被按压过程中的开关。 当按下开关时，传感器信息的拒绝允许用户界面更精确，从而便于平滑和无抖动的界面操作。
