Abstract

SISTEMA PARA LEITURA DE DADOS APRESENTADOS EM TELAS DE CRISTAL LìQUIDO, PLASMA E TUBO DE RAIOS CATóDICOS POR MEIO DA VARIAçãO DE CORES. Notadamente de um sistema que permite a leitura de dados (1) de uma tela de cristal líquido - plasma (2) ou tela (3) de tubo de raios catódicos, em que os dados (1) são preferencialmente apresentados na forma da variação do preto (P) e branco (B) convertidos em binários (A e B), seguindo um protocolo de comunicação capturado a partir de um dispositivo (4) eletrónico capaz de detectar as variações das cores (P e B) decodificando-as nos respectivos binários (A e B), remontando tais informações em um "display" (D) no mesmo dispositivo (4)DATA READING SYSTEM PRESENTED ON SCREEN OF CRYSTAL, PLASMA AND CATHEDIC RAY TUBES BY COLOR VARIATION. Notably of a system that allows reading data (1) from a liquid crystal plasma screen (2) or cathode ray tube screen (3), wherein the data (1) is preferably presented in the form of the variation of the black (P) and white (B) converted to binaries (A and B) following a communication protocol captured from an electronic device (4) capable of detecting color variations (P and B) by decoding them into their respective (A and B) by reassembling such information on a display (D) on the same device (4)
