    • A system includes a capacitively-coupled touch sensor having a conductive first layer and a conductive second layer on a first insulative layer. The width of the second layer varies along an axis of the first layer. A first excitation signal is applied to one of the first and second layers and is capacitively coupled through a touch element to the other layer, producing a first signal that produces a second signal which is digitized. Digitized peak values of the second signal are processed to compute a value for a touch element location. A conductive third layer can be placed on the opposite side of the first layer has width varying oppositely to the second layer. The first excitation signal is applied to the second layer and a non-overlapping second excitation signal is applied to the third layer. The resulting digitized peak values are processed to cancel errors due to variations.

    • An LCD precharge regulator circuit providing current directly from the input battery voltage to precharge the LCD display. A first switch activates a precharge regulator coupled to the unregulated DC input voltage, to supply the power for the initial current surge from the DC input to charge the LCD display. The precharge regulator includes a transistor and a biasing circuit. The biasing circuit initially turns the transistor fully on, but increasingly biases the transistor off as the LCD display charges to just below the operating voltage of the LCD display. A delay circuit activates a second switch after the LCD display is substantially charged, where the second switch connects the supply voltage from the DC/DC converter to the LCD display. At that point, the transistor is biased off, isolating the LCD display from the DC input voltage. Thus, the supply voltage need only sustain the charge on the LCD display after being substantially charged. Low power series resistors are provided to serve as a fuse, which fail to an open circuit condition, isolating the LCD display from high input voltage levels in the event of excessive current flowing into an overvoltage Zener diode.
    • LCD预充电调节器电路直接从输入电池电压提供电流,以预充电液晶显示器。 第一开关激活耦合到未调节的DC输入电压的预充电调节器,以从DC输入端提供用于初始电流浪涌的功率以对LCD显示器充电。 预充电调节器包括晶体管和偏置电路。 偏置电路最初将晶体管全部导通,但随着LCD显示器充电到刚刚低于LCD显示器的工作电压,晶体管将逐渐偏离晶体管。 在LCD显示器基本上被充电之后,延迟电路激活第二开关,其中第二开关将来自DC / DC转换器的电源电压连接到LCD显示器。 此时,晶体管被偏置,将LCD显示屏与直流输入电压隔离。 因此,在充电之后,电源电压仅需维持LCD显示器上的电荷。 提供低功率串联电阻,作为不能开路的保险丝,在过电流流入过压齐纳二极管的情况下,将LCD显示屏与高输入电压电平隔离。
