Hand-held computer with communication through diffuse infrared with positioning sensors

摘要

Hand-held computer with communication through diffuse infrared with positioning sensors where the diffused infrared communication is done through the geometry and design of the transmitting light-emitting diodes and of the receiving photodiodes and the position recognition system works through two glass cylinders (28 and 28a) placed at a 90 degrees angle including two contacts (29) in one of the ends of said cylinders inside which there is a freel moving mercury drop.
