Abstract

MéTODO E DISPOSITIVO PARA O RECONHECIMENTO DA MUDANçA DE ESTADO EM SINAIS DE COMUNICAçãO DE CIRCUITOS ELETRÈNICOS. Um método para que se reconheça uma mudança valida de estado, em um sinal de comunicação, que inclui sinais acoplados em modo capacitivo, recebidos por uma entrada de contato, e incluindo da manutenção da entrada de contato em um primeiro estado, e uma impedância para a primeira entrada de contato em um primeiro nível de impedância, fazendo-se a avaliação se o sinal de comunicação o qual é enviado, para a primeira entrada de contato representa uma mudança de estado válida, e alterando a entrada de contato para um segundo estado e a impedância da primeira entrada de contato para um segundo nível para a impedância, quando o sinal de tensão é validado. Um circuito de entrada de contato também é apresentado.
