  • Patent number: 11983848
    Abstract: Aspects of the disclosure provide a frame processor for processing frames with aliasing artifacts. For example, the frame processor can include a super-resolution (SR) and anti-aliasing (AA) engine and an attention reference frame generator coupled to the SR and AA engine. The SR and AA engine can be configured to enhance resolution and remove aliasing artifacts of a frame to generate a first high-resolution frame with aliasing artifacts and a second high-resolution frame with aliasing artifacts removed. The attention reference frame generator can be configured to generate an attention reference frame based on the first high-resolution frame and the second high-resolution frame.

  • Patent number: 11057248
    Abstract: A baseband system includes: an estimation and compensation circuit estimating frequency-independent non-ideal effects based on an original IQ signal pair, and compensating the original IQ signal pair based on a result of the estimation to obtain a compensated IQ signal pair; a channel estimation and equalization circuit performing channel estimation and equalization based on the compensated IQ signal pair to obtain an equalized IQ signal pair; and a tracking and compensation circuit obtaining a result of tracking of residual quantities of the aforesaid non-ideal effects based on the equalized IQ signal pair, and compensating the equalized IQ signal pair based on the result of the tracking to obtain an output IQ signal pair.

  • Patent number: 11038740
    Abstract: A communication system includes a baseband circuit, a transmitting end circuit, and a receiving end circuit is disclosed. The transmitting end circuit includes a digital analog conversion circuit and a transmitting end filtering circuit. The receiving end circuit includes a receiving end amplifying circuit, a receiving end filtering circuit, and an analog digital conversion circuit. A first data signal is transmitted to the analog digital conversion circuit through the digital analog conversion circuit and the transmitting end filtering circuit, so that the baseband circuit obtains a first compensation parameter. A second data signal is transmitted to the receiving end filtering circuit, the receiving end amplifying circuit and the analog digital conversion circuit through the digital analog conversion circuit and the transmitting end filtering circuit, so that the baseband circuit obtains a second compensation parameter.

  • Patent number: 10324505
    Abstract: A heat dissipation assembly includes a pressing unit and a heat dissipation module. The pressing unit includes a pressing plate, a plurality of elastic cantilevers and contacting members. The pressing plate can be secured on a bottom plate so that a heat source can be sandwiched between the pressing plate and the bottom plate. The elastic cantilevers are respectively disposed on the pressing plate and protruded outwards from the pressing plate to be suspended in midair. The contacting members are respectively disposed on the elastic cantilevers for abutting the bottom plate. The heat dissipation module is fixedly connected to the pressing plate and a carrier member for thermally guiding the heat source.

  • Patent number: 6857924
    Abstract: A method of producing an LED hose light includes the steps of mounting a plurality of serially connected LED strings directly on a core tube, using an intermediate tube having embedded power cords for supplying power to the LED strings to enclose the core tube having the LED strings mounted thereon, so as to form an assembly of the core tube, the LED strings, and the intermediate tube, and extending the assembly of the core tube, the LED strings, and the intermediate tube through an outer tube. The LED hose light associating LED strings with the core tube is easily bendable and energy-saving and can be produced at largely reduced cost.
