    • An on/off control circuit is provided that controls the application of power to a device. The effectiveness of the on/off control circuit is optimized with regard to cost, power consumption, component life, and utility. An R-C circuit is used to provide a time-delayed turn-on, and turn-off, of the device being controlled, accompanied by a latch that retains the on/off state and controls the coupling of a power source to the device being controlled. The latch is configured as a data flip-flop (DFF) with a clocking signal that is controlled by the time-delayed switch input. The flip-flop has an inverted output signal as its input, thereby providing a toggled on/off operation. The latch also includes an independent reset input, thereby allowing an independent turn-off operation by power management controllers within the device being controlled. In the quiescent state, the preferred embodiment consumes less than half a microWatt of power.
    • 提供了控制对设备的电力的应用的开/关控制电路。 关于成本,功耗,部件寿命和效用,开关控制电路的有效性得到了优化。 RC电路用于提供被控制的器件的延时导通和关断,伴随着保持开/关状态的锁存器,并且控制电源与被控制的器件的耦合 。 锁存器配置为具有由延时开关输入控制的时钟信号的数据触发器(DFF)。 触发器具有反相输出信号作为其输入,从而提供切换的开/关操作。 锁存器还包括独立的复位输入,从而允许被控制的器件内的电源管理控制器进行独立的关断操作。 在静止状态下,优选实施例消耗的功率小于一半微瓦。

    • A touch dimmer has a three-wire touch sensitive screen that produces an output voltage signal representative of a position of a manual pressure touch along a longitudinal axis of the touch screen. To reduce the occurrence of erroneous position indications due to low-pressure touches of the touch screen, a filter circuit is coupled to the output of the touch screen to prevent the detection of transient touches, and to prevent the detection of low-pressure touches having less than a certain actuation force. As a result, a controller may accurately determine the position of the manual pressure touch. In a preferred embodiment, two filters are coupled to the output of the touch screen. The first filter conditions the output voltage signal to allow the controller to accurately determine whether a manual pressure touch actuation has occurred. The second filter conditions the output voltage signal to allow the controller to accurately determine the position of the manual pressure touch along a longitudinal axis of the touch screen. An alternative embodiment of the touch dimmer uses a four-wire touch sensitive screen that produces a second output voltage signal representative of a position of a manual pressure touch along a transverse axis of the touch screen. The first filter is coupled to receive the second output signal to permit accurate detection of a manual pressure touch actuation.
    • 触摸调光器具有三线触敏屏幕,其产生表示沿着触摸屏的纵向轴线的手动压力触摸位置的输出电压信号。 为了减少由于触摸屏的低压触摸引起的错误位置指示的发生,滤波器电路耦合到触摸屏的输出以防止瞬态触摸的检测,并且防止检测到具有 小于一定的致动力。 因此,控制器可以准确地确定手动压力触摸的位置。 在优选实施例中,两个滤波器耦合到触摸屏的输出端。 第一个滤波器调节输出电压信号以允许控制器准确地确定是否发生了手动压力触摸致动。 第二个滤波器调节输出电压信号,使控制器能够准确地确定沿着触摸屏纵轴的手动压力触摸的位置。 触摸调光器的替代实施例使用四线触敏屏幕,其产生表示沿着触摸屏的横轴的手动压力触摸位置的第二输出电压信号。 第一滤波器被耦合以接收第二输出信号以允许对手动压力触摸致动的精确检测。
