  • Patent number: 11127673
    Abstract: A method (of generating a layout diagram) includes: generating one or more first conductive patterns representing corresponding conductive material in the first metallization layer, long axes of the first conductive patterns extending substantially in a first direction; generating a first deep via pattern representing corresponding conductive material in each of the second via layer, the first metallization layer, and the first via layer; relative to the first direction and a second direction substantially perpendicular to the first direction, aligning the first deep via pattern to overlap a corresponding component pattern representing conductive material included in an electrical path of a terminal of a corresponding transistor in the transistor layer; and configuring a size of the first deep via pattern in the first direction to be substantially less than a permissible minimum length of a conductive pattern in the first metallization layer.

  • Publication number: 20150025657
    Abstract: An electronic device includes a first machine assembly, a second machine assembly, a first sensor, a second sensor, and a control circuit. The second machine assembly is pivoted to the first machine assembly. The first sensor is located on the first machine assembly and configured to generate first sensing data when the electronic device is in a non-normal working state. The second sensor is located on the second machine assembly and configured to generate second sensing data when the electronic device is in the non-normal working state. The control circuit is coupled to the first sensor and the second sensor and configured to perform a first default operation according to the first sensing data and the second sensing data.

  • 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.
