  • Patent number: 12068753
    Abstract: The present invention discloses a signal gain tuning circuit having adaptive mechanism. An amplifier receives an analog signal to generate a tuned analog signal to an ADC circuit to further generate a digital signal. A gain control capacitor array and the amplifier together determine a gain of the tuned analog signal. The control circuit receives an actual level of the digital signal to determine an offset of the digital signal and an estimated level to generate a tuning control signal. Each of coarse-tuning capacitors of a coarse-tuning capacitor array corresponds to a first tuning amount relative to a maximal gain. Each of fine-tuning capacitors of a fine-tuning capacitor array corresponds to a second tuning amount relative to the maximal gain. A tuning capacitor enabling combination of the coarse-tuning and fine-tuning capacitor arrays are determined according to the tuning control signal to tune the gain and decrease the offset.

  • Publication number: 20240181568
    Abstract: A method for producing graphene, configured for forming a graphene layer on a surface of an object. The method includes steps of: depositing a poly-p-xylene material layer on the surface: and converting the poly-p-xylene material layer into a graphene layer by using a laser sintering process or a plasma-assisted sintering process.

  • Patent number: 9753316
    Abstract: A supporting base includes a bottom plate and a plurality of stepwise supporting structures connected with and raised up from a plurality of side edges of the bottom plate. Each stepwise supporting structure includes a plurality of raising segments and at least one supporting segment. The plurality of raising segments and the at least one supporting segment are alternately arranged. The at least one supporting segment is substantially parallel to the bottom plate. The lowest raising segment has a bottom end connected with one of the side edges of the bottom plate. A thickness of at least one of the at least one supporting segment is greater than that of at least one of the plurality of raising segments. A display device using the support base is also provided to improve assembling efficiency and reduce cost.

  • Patent number: 8755190
    Abstract: A housing of an electronic device includes a first housing body, a second housing body and a buffer. The first housing body defines an accommodating recess. The second housing body is assembled to the first housing body and adapted to be foldable relative to the first housing body. The buffer is disposed on the second housing body. In a closed position, the second housing body and the first housing body are stacked with each other, the accommodating recess is recessed away from the second housing body, the buffer faces the first housing body, and the buffer substantially overlaps with a fringe of the accommodating recess.
