Abstract

Patent of invention of a 'COMMUNICATION SYSTEM BY DIFFUSED INFRARED RAYS' which uses the non-directionals infrared rays obtained through the geometry of position of infrared transmitters and receivers and their characteristics of 'design' and transmission power chosen and the conception of the electronics circuits, showing at minimum one diffuse infrared transceiver (1) which has a minimum one led with half angle of transmission of around 15 grades and a minimum one led with half angle of transmission of approximately 35 grades installed in one board (21) with angle approximated of 30 grades made in relation to the perpendicular line to board (21 - A-A') and the transversal line from the minor base (19) and a minimum one communication processor (2) has one RISC microcontroller (4), this one having internally DRAM, ROM and DMA memories controllers and asynchronous serials interfaces, with the EPROM BOOT memory (4a), FLASH memory (4b) and dynamical RAM memory (4c), interface Ethernet 10baseT kind (3a) implemented using a controller (3b) and a transformer (3c) specific to this reason.
