    • A control unit comprising a light guide is formed and positioned in a circuit board for providing visual indication to a user of an appliance, such as a cooktop. The light guide receives light from a source, typically in the form of an LED on the circuit board, typically positioned laterally to the light guide, and the light guide receives and directs the light to the user. In some embodiments, the light guide is positioned behind a cover, which may have indicia thereon for providing operating information to the user. Portions of the light guide may be coated with an electrically conductive coating so as to also form a portion of a capacitance touch switch for detecting user input for controlling operation of the appliance.
    • 包括导光体的控制单元被形成并定位在电路板中,以向用户提供视觉指示,例如灶具。 光导件从源极接收光,通常以电路板上的LED的形式,通常位于光导的横向方向,并且光导接收并引导光到用户。 在一些实施例中,光导被定位在盖子的后面,盖可以在其上具有用于向使用者提供操作信息的标记。 导光体的一部分可以涂覆有导电涂层,以便也形成用于检测用户输入以控制器具的操作的电容式触摸开关的一部分。

    • A circuit provides an output signal in accordance with crossing points of a differential signal, which includes a normal input signal and a complementary input signal. The circuit includes a first amplifier for amplifying a first signal difference between the normal input signal and a first threshold value, and for providing as a first output signal the amplified first signal difference. The circuit includes a second amplifier for amplifying a second signal difference between the complementary input signal and a second threshold value, and for providing as a second output signal the amplified second signal difference. The circuit also includes a first comparator for providing a first logical level when a third signal difference between the first output signal and the second output signal is greater than a third threshold value, and for providing a second logical level when the third signal difference is smaller than the third threshold value.
    • 电路根据包括正常输入信号和互补输入信号的差分信号的交叉点提供输出信号。 该电路包括用于放大正常输入信号和第一阈值之间的第一信号差的第一放大器,以及用于将放大的第一信号差作为第一输出信号。 电路包括用于放大互补输入信号和第二阈值之间的第二信号差的第二放大器,并且用于将放大的第二信号差提供为第二输出信号。 该电路还包括第一比较器,用于当第一输出信号和第二输出信号之间的第三信号差大于第三阈值时提供第一逻辑电平,并且用于当第三信号差较小时提供第二逻辑电平 超过第三阈值。
