  • Publication number: 20220343875
    Abstract: An electronic device, an electronic system, and a control method are provided. The electronic device includes a display, a memory, and a processor. The memory stores an audiovisual module and a control module. The processor receives initial image information from an external electronic device through a bridge device. The processor is coupled to the display and the memory. The processor executes the audiovisual module to transform the initial image information with a first image format into transformed image information with a second image format, which is compatible to the display. The processor controls the display to display according to the transformed image information. The processor executes the control module to receive a control signal for operating the transformed image information, and provide the control signal to the external electronic device through the bridge device.

  • Patent number: 8125467
    Abstract: A touch sensor with a sliding structure is disclosed. The touch sensor includes a first touch detecting plate, a second touch detecting plate, and a capacitance-to-digital converter. The first touch detecting plate includes a first tilt portion, and the second touch detecting plate includes a second tilt portion, wherein a bevel edge of the second tilt portion is parallel to a bevel edge of the first tilt portion. The first touch detecting plate and the second touch detecting plate form a parallelogram slide detecting area. The first touch detecting plate transmits a first detected capacitance, and the second touch detecting plate transmits a second detected capacitance. The capacitance-to-digital converter generates a sliding state detected value according to the first detected capacitance and the second detected capacitance.

  • Publication number: 20100214253
    Abstract: A method and an apparatus adapted to a capacitive touch panel for drift compensation are provided, wherein the touch panel includes a plurality of sensors. In the method for drift compensation, a plurality of capacitances respectively sensed by each of the sensors are extracted. Whether the touch panel is in a proximity state is determined upon a slope of the sensed capacitances and a slope parameter. Whether each of the capacitances is drifted is determined upon the capacitance and an allowable noise range. When the touch panel is not in the proximity state and each of the capacitances is drifted, each of the capacitances is compensated according to a drift error of each of the capacitances after a first presetting time has passed.

  • Patent number: 7675361
    Abstract: A class-D amplifier and a method of generating a multi-level output signal thereof are provided. The class-D amplifier includes a controlling logic circuit and an output module. The controlling logic circuit analyzes the amplitude of an input signal to generate a voltage modifying signal. A power supply provides a voltage according to the voltage modifying signal. The controlling logic circuit generates controlling signals according to the input signal. The output module generates an output signal to drive a load according to the voltage and the controlling signals. In other words, the resolution of the amplitude of the output signal is increased by modifying the voltage, and a signal to noise ratio is then increased.
