Patents by Inventor Hong-Hao Kang

Hong-Hao Kang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8605403
    Abstract: A thermal protection circuit to protect an electronic device from over-heat comprises a temperature sensor, a hysteresis comparator and a switch circuit. The temperature sensor senses internal temperature of the electronic device and output an internal temperature signal with voltage. The hysteresis comparator outputs a power-off signal when the voltage of the internal temperature signal is lower than a low voltage threshold representing an a determined temperature, or outputs a power-on signal when the voltage of the internal temperature signal is higher than a high voltage threshold representing a restarting temperature. The switch circuit stops transmitting power signals to the electronic device in response to the power-off signal, or continues to transmit the power signals to the electronic device in response to the power-on signal.

  • Patent number: 8203400
    Abstract: A broadband filter filtering noise over a first conductive wire, a second conductive wire, and a third conductive wire includes a differential-mode filtering circuit connected to both the first conductive wire and the second conductive wire and a common-mode filtering circuit connected to both the first conductive wire and the second conductive wire. The differential-mode filtering circuit includes two inductors and two capacitors for filtering differential-mode noise of different frequencies. The common-mode filtering circuit includes two inductors and six capacitors filtering common-mode noise of different frequencies.
