Patents by Inventor Yao-Chang Hsieh

Yao-Chang Hsieh 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: 11647280
    Abstract: The present disclosure discloses a dual-processor electronic apparatus operation method used in a dual-processor electronic apparatus that includes steps outlined below. A first processor is activated in an initialization procedure. A second processor is activated by the first processor to enter an operation mode. The first processor is deactivated in the operation mode, and the second processor executes a predetermined procedure. Whether a predetermined event occurs during the execution of the predetermined procedure is determined by the second processor such that event information is stored when the predetermined event occurs and the first processor is activated. The event information is accessed and processed by the first processor.
    Type: Grant
    Filed: December 28, 2021
    Date of Patent: May 9, 2023
    Assignee: SIGMASTAR TECHNOLOGY LTD.
    Inventors: Fu-Cheng Chen, Chao-Kai Chang, Yao-Chang Hsieh

  • Patent number: 8175106
    Abstract: The present invention applies management frame defined in IEEE 802.11 standard to a wireless distribution system (WDS) mode by adding an information element (IE) into the management frame, which enables any access point (AP) in WDS to maintain IE based on its own setting and state, then send IE via the management frame for providing state of the AP under WDS mode, determine whether a physical link (i.e., a wireless link between APs) should be established therewith based on received IE, and maintain the established physical link through the wireless management frame in a real time manner. Thus, the existence and necessity of the physical link between different APs in WDS can be determined correctly.
