Abstract

TRANSMISSãO DE SINAL EM UM SISTEMA DE LEITURA DE PRESSãO PNEUMáTICA". Aparelho para uso, por exemplo, em sistema de leitura passiva tal como em um sistema de leitura de pressão pneumática em um veiculo que abrange um conjunto de circuitos transmissores (1) e um conjunto de circuitos receptores (4) acoplados por um acoplador (C,:) preferencialmente um acoplador sem fio tal como duas antenas em forma de placa opostas. O conjunto de círcuitos transmissores (1) inclui um ressonador (10) que tem pelo menos um componente (C~ v~) cujo valor influencia uma freq³ência ressonante natural do meio ressonante e que pode ser alterado no uso do conjunto de circuitos. O valor efetivo é alterado, por exemplo, por meio de um parâmetro físico sendo lido ou por um sinal de controle a ser transmitido. O conjunto de circuitos receptores (4) inclui uma seção acionadora (12) para aplicar ao ressonador (10) um sinal de excitação tendo uma freq³ência de excitação pré-determinada que é diferente da freq³ência ressonante natural. O conjunto de circuitos transmissores (1) preferencialmente obtém seu fornecimento de energia a partir do sinal de excitação via um circuito retificador (14). O conjunto de circuitos receptores detecta tal mudança no valor efetivo via acoplador.
