Patents by Inventor Hung-Chi LU

Hung-Chi LU 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 device and work-frequency reducing method thereof
    Patent number: 10782674
    Abstract: An electronic device and a work-frequency reducing method thereof are disclosed. The electronic device at least includes a case, a gravity sensor, a pressure sensor and a processing unit. The gravity sensor detects the gravity status of the electronic device and outputs a plurality of gravity detecting signals. The pressure sensor detects the pressure status of the bottom portion of the case and outputs a plurality of pressure detecting signals. The work-frequency reducing method includes the following steps: receiving the gravity detecting signals and judging whether the variation value of the gravity detecting signals is greater than a default gravity value or not; if yes, decreasing the working frequency of the processing unit; receiving the pressure detecting signals and judging whether the pressure detecting signals are greater than a default pressure value or not; and if no, restoring the working frequency of the processing unit.
