CHI-TEIN YEH 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).

  • CONTROL METHOD AND ELECTRONIC STYLUS FOR TOUCH INPUT TO A CAPACITIVE TOUCHPAD MODULE
    Publication number: 20140035870
    Abstract: An electronic stylus emits an excitation signal to apply to a trace of a capacitive touchpad module near a touch point when the electronic stylus touches the capacitive touchpad module, so as to change a waveform of a charging/discharging signal in the trace, and depending on the waveform variation, the capacitive touchpad module can identify the touch point.
    Type: Application
