35 results about "Light pen" patented technology

A light pen is a computer input device in the form of a light-sensitive wand used in conjunction with a computer's cathode-ray tube (CRT) display. It allows the user to point to displayed objects or draw on the screen in a similar way to a touchscreen but with greater positional accuracy. A light pen can work with any CRT-based display, but its ability to be used with LCDs was unclear (though Toshiba and Hitachi displayed a similar idea at the "Display 2006" show in Japan).

R The system includes an ammeter and a central processor and display. Through an array of injection pens and corresponding sampling electrodes, a multi-parallel resistance detection circuit is established in the vertical direction of the coal gangue material. This enables simultaneous adaptive full-envelope power feeding of a large number of irregular coal gangue materials. Based on resistance, a large number of coal gangue materials are identified simultaneously, and resistance and coal gangue image displays are displayed. This solves the problems of inaccurate monitoring when the surface of coal gangue materials is contaminated and the low efficiency of single-point identification, achieving a highly reliable and efficient identification technology for the resistance sensing and intuitive monitoring (display) of coal gangue materials.
