Abstract

"SEMáFORO, COM SINAIS ACUSTICOS E INDICAçãO DE CONTAGEM REGRESSIVA" Trata-se de um semáforo, do tipo que usa luzes preparadas em três setores nas suas telas sinalizadoras, diferentes em sua colocação e regulagem de cor normalizada internacionalmente, e no qual as telas são controladas por um processador (a) ligado eletricamente a um contador ótico e numérico (b) que, por sua vez, é ligado a um dispositivo emissor de sons (c), sendo que cada setor abriga uma pluralidade de luzes alimentadas por seções independentes, que são conectadas eletricamente desde contador ótico e numérico (b), cujo circuito de formação ótica é programado em seq³ência e tempo para a emissão de sinais ativadores para certas seções das luzes, dando a iluminação do sinal em cada tela; simultaneamente, o circuito da formação numérica desse contador está programado para enviar sinais de interrupção da fonte de alimentação a certos setores das luzes, dando lugar à visualização de números em contagem regressiva, formados por contraste, entre as luzes com sinal de ativação e luzes com sinal de interrupção; e ainda, simultaneamente e no início de cada sinal do semáforo, esse emissor de som é conectado eletricamente aos meios acústicos instalados na tela, o qual receberá e emitirá os sinais distintos de audiofrequência para cada uma das cores da tela.
