Abstract: A key system utilizes two operation nodes to detect the status of a plurality of keys, and each operation node can output and read a high, a low, and a clock signal. When an operation node outputs a high signal and reads a return signal and then outputs a low signal and reads a return signal, the other operation node outputs a clock signal. Therefore, the two operation nodes can detect the status of six keys.

Abstract: A packing cushion with multilayer substrates is applicable to wrap an article and provide buffer protection. The packing cushion includes: one or more tube sheet, equipped with plural air chambers for buffer protection after air-filling and expansion; and at least one slice body(s), attaching closely to a side of the tube sheet to prevent the tube sheet from being poked through and broken. When the tube sheet is expanded by filling air, the slice body(s) or the tube sheet may be used to wrap the article. The tube sheet provides the article a perfect buffer protection to prevent from damage or scratch during transportation. Therefore the wrapping cost of the article may be further reduced, meanwhile the environmental pollution problems caused by the buffering materials in the prior art may be solved.

Abstract: Frames are utilized to display an image of low resolution on a display device of high resolution. All scanlines utilized for generating the image are turned on to display the image data of the display area in a first frame, and part but not all of the scanlines not utilized for generating the image are turned on to display the blank data of the non-display area in the first frame. Thus, the blank data of the non-display area are displayed in multiple frames.
