  • Publication number: 20240178536
    Abstract: A cross-coupling structure for dielectric cavity filters includes a base and a tuner. The base is communicated with plural resonant cavities, a side through hole and a blind hole, and has a first channel formed between two adjacent resonant cavities which are not used for producing cross-coupling, and a second channel the resonant cavities formed between two adjacent resonant cavities which are used for producing cross-coupling. The side through hole is penetrated through the base and communicated with the second channel. The blind hole is formed on a wall of the second channel and has an opening facing the side through hole. The tuner is entered into the second channel from the side through hole and extended into the blind hole and can be adjustably moved between the opening of the blind hole and the bottom of the blind hole to set a cross-coupling amount target value.

  • Patent number: 8942513
    Abstract: A de-warping processing method for digital images includes the following steps. A first image window is segmented into a plurality of first blocks. A second image window is segmented into a plurality of second blocks according to locations and an amount of the first blocks. A coordinate transformation parameter is calculated by a group of first vertex coordinate values of the first block and a group of second vertex coordinate values of the corresponding second block. Each of coordinate values of the first block is transformed into an estimated coordinate value of the corresponding second block according to the coordinate transformation parameter. A pixel content value is obtained from the second image window according to each of the estimated coordinate values, and is written into a pixel with the corresponding coordinate value in the first block. All the first blocks are processed for outputting a first image.
