  • Patent number: 7521927
    Abstract: A magnetic induction switching circuit comprising a magnetic induction device for sensing a magnetic field and generating signals corresponding to the polarity of the field. A detection control unit detects the signals generated in response to a magnetic field and configures a programmable switching unit so that the first signal generated in response to a detected magnetic field having a first polarity is coupled through the switching unit and subsequent signals generated in response to detecting different polarity magnetic fields are not coupled through the switching unit.

  • Patent number: 7242187
    Abstract: A Hall Effect switching circuit and apparatus and method using the same are disclosed. The Hall Effect switching circuit comprises a power supply device, a Hall Effect detecting device and a buffer. The power supply device provides operation power to the Hall Effect detecting device. The Hall Effect detecting device provides a first triggering signal to a first output pin and a second triggering signal to a second output pin in accordance to a magnetic field through the Hall Effect detecting device. The buffer receives and buffers the voltage levels of the first/second triggering signals.
