  • Patent number: 8808014
    Abstract: The instant disclosure relates to a plug connector for inserting into at least one hole of an electrical outlet. The plug includes a plug body, a switch, a pushing member, at least one conductive member, and at least one locking member. The plug body is constructed of at least one shell defining a via hole, where the via hole penetrates entirely through the shell. The switch has a connecting end inserted through the via hole for connecting pivotally to the pushing member. The conductive member protrudes from the plug body, and the locking member is arranged in close to the conductive member. Thus, when the switch is operated, the connecting end is driven to push the pushing member to move with respect to the conductive member, and the locking member is pushed by the pushing member to deform or move.

  • Patent number: 7308137
    Abstract: A method of determining color composition of an image includes calculating an intensity value and a saturation value for each pixel of the image, comparing the calculated intensity and saturation values for each pixel with first and second predetermined threshold values, respectively, and labeling pixels with calculated intensity values above the first predetermined threshold value and calculated saturation values above the second predetermined threshold value as color pixels. Next, a mask is applied to the image and the number of color pixels selected by the mask is counted. If the number of color pixels selected by the mask is greater than or equal to a predetermined density value, the image is determined to be a color image.

  • Patent number: 7272266
    Abstract: A method for correcting faded colors in aged photographs or film. The method automatically restores the color of the image by analyzing the color variance in the image and determining tonal curve for each channel. First, the interior of the image is selected and the image is portioned into sub-images. The variance of each sub-image is calculated, and the parameters are evaluated for correcting the entire image during scanning. This method will provide good color quality and preserve good density of the image.

  • Patent number: 7165232
    Abstract: An I/O circuit placement method. In the I/O circuit placement method, at least two rows of I/O circuits are placed on a first side of the chip, and each I/O circuit has a head section and a tail section. The placement direction of the head section and the tail section is perpendicular to the placement direction of the I/O circuits in the rows. The semiconductor further has a core circuit disposed on the chip, wherein the rows of I/O circuits are disposed outside the core circuit and are at the periphery of the chip. Due to the I/O circuit placement in the semiconductor device, the present invention reduces the area of the semiconductor chip and fabrication cost.

    Abstract: The invention relates to a method for detecting a tilted angle when it scans the document. First, the present invention scans the document to produce a first scanned data, and the fist scanned data is transformed into a binary image. The present invention determines whether the binary image comprises a graphic area. If the binary image comprises the graphic area, the present invention deletes the graphic area from the binary image to produce a deleted binary image; moreover, it uses a predetermined way, based on the deleted binary image, to calculate the tilted angle.
