The design of touch-screen with high resolution infrared based on plastic optical fiber and image processing

Abstract

Main defects of infrared touch screen are low resolution and sensors to be easily damage, which makes it can't realize the accurate positioning. To overcome infrared screen principle inherent defects, we propose a new solution by the principle of innovation, with a laser tube instead of the infrared emission tube, plastic optical fiber instead of the infrared receiver, CMOS sensor instead of complex circuits, which resulting a design of touch-screen with high resolution infrared based on plastic optical fiber and image processing. Currently, it does effectively handle the problem of the low revolution, poor stability and the complex maintenance of infrared touch screen, to make it a great business prospects.

Lithium vanadium phosphate as cathode material for lithium ion batteries

“…Recent results have demonstrated that carbon coating is primarily dependent on the carbon source. Therefore, various carbon sources have been employed for carbon-coated LVP, such as glucose [12,40,85,[107][108][109], sucrose [110][111][112], maltose [113], citric acid [47,[114][115][116], starch [117], carbon black [118], EDTA [119], PS spheres [71,120], β-cyclodextrin [121], carboxy methyl cellulose (CMC) [122], PEG-400 [123], and PEG-10,000 [124], etc.…”
