Hao-Hsiang Hung 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: 12235789
    Abstract: An electronic device includes a first power input end, a second power input end, a detection circuit, and a power delivery controller. The first power input end is adapted for coupling to an alternating current adapter. The second power input end is adapted for coupling to a dual-role port device. The detection circuit is coupled to the first power input end and the second power input end. The power delivery controller is coupled to the detection circuit and configured to control the dual-role port device to switch from a source end to a sink end in response to the detection circuit detecting that the first power input end receives an adapter source voltage from the alternating current adapter and the second power input end bring to the dual-role port device.
