Abstract: A full-zone optical image addressing apparatus, including an addressing device, an image extraction converter, a comparator, an AND gate and a counter. The addressing device is located at the enclosure of the scanner and includes a plurality of geometric patterns. Each of the geometric patterns includes a plurality of rows of pixels. While receiving an exposure signal, the image extraction converter extracts one row of pixels from the addressing device, such that a series of analog signals is obtained and output to the comparator. The comparator then compares the series of analog signals to an analog critical voltage to output a series of analog comparison signals to the AND gate. The AND gate synchronously processes the series of analog comparison signals and a pixel rate clock to output the pixel data corresponding to the extracted row of pixels to the counter.

Abstract: A floor drain cover includes a draining frame, a net-shaped disk mounted in the top wall of the draining frame, a fixing bracket mounted on the draining frame, a movable lid pivotally mounted on the fixing bracket and movable relative to the draining frame, and a rubber pad mounted on the movable lid and movable to seal the bottom wall of the draining frame. Thus, when the ambient waste water in the floor drain flows toward the draining frame, the movable lid is pressed by the pressure of the ambient waste water so that the movable lid moves the rubber pad to seal the bottom wall of the draining frame, thereby preventing the ambient waste water in the floor drain from flowing backward, and preventing the floor from being contaminated by the ambient waste water.

Abstract: A method of effacing zipper image, applicable to scan a document by a scanner with a stagger charge-coupled device. The nth (n is a positive integer) pixel value obtained by scan on a scan line at which the zipper image is produced is subtracted by the (n+1)th pixel value obtained by scan on the scan line. The absolute value of the result is then compared to a critical value. If the result is smaller than the critical value, the nth pixel is modified by the method.
