Publication number: 20130052494Abstract: A power storage device is provided with an upper cover, a cell module and a lower cover. A tab joint portion is locally formed at each of two sides of the cell module to be welded and assembled with a tab. When welded with the tab joint portion, the tab merely needs to be placed horizontally or be slightly at an inclination angle, and one-time bending is performed on an electrical connection part on the tab, so as to be electrically connected to an electrode of the upper cover. Therefore, the situation that a plasticized metal protective film wrapped on the outer edge of the tab or the cell module is easy to crack caused of many times of bending in the prior art can be improved.Type: ApplicationFiled: July 18, 2012Publication date: February 28, 2013Inventors: Hsiu-Hsiang PEI, Yen-Teng SU, Kun-Miao TSAI, Yao-Min CHIU, Jesse CHEN, Chih-Jung LIN

Patent number: 8331717Abstract: Block noises at block boundaries are removed, but when a contour line in the original image matches a block boundary, the degree of block noise removal is adjusted and image quality is improved. An adaptive filter has a step of calculating the weight of pixels near the block boundary by a high-pass filter, and a step of determining an adjusted value for the pixels near the block boundary based on the weight. The pixel values near the block boundary are adjusted and block noises are removed. A low-pass filter is applied to pixels near the block boundary to determine a filtered value. The adjusted values of the pixels near the block boundary are determined by obtaining a weighted sum of the original pixel value and the filtered value.Type: GrantFiled: October 2, 2008Date of Patent: December 11, 2012Assignee: Panasonic CorporationInventors: Pei-Lin Hou, Chih-Jung Lin, Satoshi Kondo

Patent number: 8265138Abstract: An image processing method, and an apparatus and an integrated circuit for implementing the method are adapted for use in a liquid crystal display. The method includes the steps of: determining which blocks in a decoded current frame are noisy blocks; finding, in a processed reference frame, a most similar reference block for each noisy block and generating a block velocity for each noisy block; and processing pixels that are in the noisy blocks having block velocities smaller than a liquid crystal response rate of the liquid crystal display, and that are not covered by after-images. The present invention utilizes the characteristics of liquid crystals to increase processing speed.Type: GrantFiled: May 1, 2007Date of Patent: September 11, 2012Assignee: Panasonic CorporationInventors: Pei-Lin Hou, Chih-Jung Lin

Patent number: 8244054Abstract: Image ringing noise is reduced by calculating a line spread function value of each pixel's luminance in an input image, dividing the input image into a plurality of blocks, and calculating an average value and a maximum value of the line spread function values for all pixels in each block. Based on the average value and the maximum value of the line spread function values of each block, whether a block is an interfered flat block or a non-interfered block is determined and the pixels in the interfered flat block are set as noisy pixels. Whether each pixel in the non-interfered block is an edge pixel or a non-edge pixel is determined and the non-edge pixels in the non-interfered block are set as noisy pixels. The noisy pixels thus set are smoothed, and the smoothed pixels are combined with the edge pixels for output as an output image.Type: GrantFiled: July 25, 2007Date of Patent: August 14, 2012Assignee: Panasonic CorporationInventors: Chih-Jung Lin, Pei-Lin Hou
