  • Patent number: 8928331
    Abstract: A diagnostic circuit for trouble shooting electronic control units of appliances includes a voltage sensing and signal generation device with an input/output and an input. The circuit includes first terminals for connecting to the load and second terminals for connecting to the two lines of the sinusoidal source. One of the first terminals is connected to the input/output, and another one of the first terminals is connected to the input. A relay is connected between one of the second terminals and the input/output. Another relay is connected between another one of the second terminals and the input. A first diode pair with clamping diodes is connected to the input/output, and a second diode pair first diode pair with clamping diodes is connected to the input.

  • Publication number: 20110187204
    Abstract: An inductive touch key switch assembly and circuit are provided. The circuit optimizes signal strength and noise immunity by reducing the number of long paths through the circuit board and localizes the driver circuit to each key switch assembly sensor coil. The key switch assembly optimizes placement of the target to enable the user interfaces on domestic appliances and products having present values of front panel thickness.
