Patents by Inventor Zi hong Zhang

Zi hong Zhang 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).

  • Electronic protection against circuit reversal
    Patent number: 10206263
    Abstract: A device having an active reversal protection system is described. The system includes a pair of MOSFETs connected to parallel battery power sources. When the batteries in one of the power sources are improperly installed, the voltage delivered by that power source closes the gate of its associated MOSFET. In normal operation, the MOSFETs are connected to a microprocessor configured to operate the device. In a preferred embodiment, the device is a lighting device incorporating a light emitting diode that is driven by the MOSFETs.
    Type: Grant
