  • Patent number: 10585512
    Abstract: A touch display device includes: a timing controlling unit generating a touch synchronizing signal, an image data, a data controlling signal and a gate controlling signal; a micro controlling unit generating first to third selecting signals; a touch power unit including a MUX input part and a MUX part, the MUX input part deactivated during a display period and activated during a touch period, the MUX part generating a modified common voltage and first and second gate low voltages; a data driving unit generating a data voltage; a gate driving unit generating a modified gate voltage; and a touch display panel displaying an image during the display period and sensing a touch during the touch period.

  • Patent number: 10553464
    Abstract: A method for controlling a semiconductor manufacturing facility includes measuring output change amounts of differential pressure sensors in the facility when pressure conditions change by a number of fans. The fans are then classified into different groups and subgroups and control sequences of the subgroups are determined based on the change amounts. Difference values are then calculated, and a control signal is generated to adjust the rotation speed of the fans.

  • Publication number: 20020184924
    Abstract: A recoating method for an optical fiber recoats a uniform thickness of resin on a covering-resin-removed-area of an optical fiber. The covering-resin-removed-area is rotated relatively to a resin supplying device while supplying the resin to the covering-resin-removed-area.

  • Patent number: 5877804
    Abstract: The present invention provides a method for detecting a moving object and apparatus for the same. The image data ?.DELTA..sub.ij (k)! outputted by subtracter 4 are alternatively contained in image buffers 21 and 22. In subtracter 24, the image data ?.DELTA..sub.ij (k-1)! of one timing beforehand is removed from the image data ?.DELTA..sub.ij (k)! of the present time point. In addition, the image data ?.DELTA..sub.ij (k-1)! of one timing beforehand and the image data ?.DELTA..sub.ij (k)! of the present time point are compared using comparator 25. In this case, if image data ?.DELTA..sub.ij (k)! and image data ?.DELTA..sub.ij (k-1)! differ, the image data ?.DELTA..sub.ij (k-1)! of one timing beforehand is supplied to subtracter 26. The initial moving object image is excluded by subtracter 26. Consequently, it is possible to precisely distinguish the shape, size, etc. of a moving object without traces (afterimage) of the moving object at the present time point remaining in the final image data ?.DELTA..sub.
