Yu-Sheng 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).

  • Patent number: 11349325
    Abstract: A pulse controlled charging method for higher temperature charging in addition to the current-reducing operation at ambient temperature. A specific software control strategy for these purposes is proposed, which can be divided into two parts, (a) two-stage charging current control at ambient temperature, which sets different current-limiting transient points for chargers with different outputs; (b) high-temperature pulse charging, which utilizes an internal NTC (Negative temperature coefficient) thermistor inside the charger to detect the internal temperature of the charger, if the temperature exceeds a pre-determined value, the charging process will be stopped for a period of time to avoid the temperature of the charger becoming too high.
    Type: Grant

  • Patent number: 9529452
    Abstract: A touch input device includes a touch end, a sensing module, and a receiving module. The sensing module includes a sensing unit and a signal operation unit. The sensing unit detects a relative angle between the touch end and a display touch surface to generate a motion signal. The signal operation unit is coupled with the sensing unit and generates a result signal according to the motion signal. The receiving module includes a receiving end and a demodulator unit. The receiving end receives the result signal; the demodulator is coupled with the receiving end, wherein the receiving end transmits the result signal to the demodulator unit, and the demodulator unit generates a function signal according to the result signal.
