  • Publication number: 20180288891
    Abstract: A hinge and an electronic device using the same are disclosed. The hinge includes a fixing member, a shaft member, and a spring member. The fixing member includes a pivoting portion and a fixing portion. The pivoting portion and the fixing portion are respectively fixed to opposite ends of the fixing member. The shaft member is pivotably connected to the pivoting portion. The spring member includes a spring body, a first end, and a second end. The spring body is between the first end and the second end. The first end is fixed to the shaft member. The second end is fixed to the fixing portion. When the shaft member rotates, the shaft member drives the spring body to twist via the first end.

  • Publication number: 20170201225
    Abstract: An all-pass wideband phase shifter is introduced. Series connections in parallel between two 3 dB hybrid couplers include combining two 90-degree phase shifters and two attenuators to form a novel phase shifter framework. Under specific controls of continuous 90-degree phase shifters and attenuators in four quadrants, 360-degree all-pass phase shifting is effected by phase shifting and vector composition.

  • Patent number: 9148309
    Abstract: An apparatus for estimating channel effects is provided. A receiving module receives first data and first reference information arriving in a first time period, second data and second reference data arriving in a second time period, and third data and third reference data arriving in a third time period. An estimation module estimates channel effects corresponding to the first and third data, and the first, second and third reference data, respectively. A coefficient calculation module performs a Wiener filter coefficient calculation on the channel effects corresponding to the first, second and third reference data to generate a set of time-domain interpolation coefficients. An interpolation module interpolates the channel effects corresponding to the first third data according to the set of time-domain interpolation coefficients to generate a channel effect corresponding to the second data.

  • Patent number: 8942328
    Abstract: A timing recovery apparatus for compensating a sampling frequency offset of an input signal is provided. The timing recovery apparatus includes a timing error corrector configured to generate an output signal according to the input signal and a calibration signal, a gain controller configured to adjust at least one of a signal edge low-frequency error component and a signal edge high-frequency error component of the output signal and accordingly generate an adjusted signal, a timing error detector configured to generate an error signal according to the adjusted signal, and a calibration signal generator coupled to the timing error detector and the timing error corrector, for generating the calibration signal according to the error signal and outputting the calibration signal to the timing error corrector to compensate the sampling frequency offset of the input signal.
