Liao Chen Han 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: 7561401
    Abstract: A protector for an electric device comprises a driving device and a voltage stabilizing device serially connected to the voltage stabilizing device. After a switch of a power source is turned on, a current of high voltage flows into the voltage stabilizing device. Two conductive plates inside the voltage stabilizing device are electrically conducted and a current flows into the driving device. A spring plate having a semiconductor chip is then separated from an other spring plate and then returns back to contact together with the other spring plate. Meanwhile, the extra current of the power source is consumed such that the surge current instantly generated from power source is consumed, and damage to the electric device is prevented.

    Abstract: A protector for an instant driving circuit of an electric device comprises a driving device and a voltage stabilizing device, the driving device being serially connected to the voltage stabilizing device. When the protector is connected to a driving circuit of an electric device, after the switch of a power source is turned on, a current of high voltage of the power source flows into the voltage stabilizing device, and the two conductive plates installed inside the sealed tube of the voltage stabilizing device are electrically conducted due to the function of a gas filled in the sealed tube of the voltage stabilizing device, and a current flows into the driving device. The spring plate having a semiconductor chip is then instantly separated from the other spring plate for a very short time and then returns back to contact together with the other spring plate, so as to trigger the electric device(s).
