Abstract

Patente de Invenção: <B>"SISTEMA PARA TROCA DE DADOS POR MEIO DE COMUNICAçãO SEM CONTATO ENTRE UM TERMINAL E OBJETOS PORTáTEIS ACIONADOS POR CONTROLE REMOTO"<D>. O terminal (100) inclui uma bobina (102) cooperando com um dispositivo de transmissão/recepção de dados (108-118). O objeto portátil (200) incluindo um circuito elétrico acionado à distância compreendendo: uma bobina (202) para captar o referido campo magnético modulado proveniente do terminal ou para produzir uma resposta por distúrbio modulado do dito campo magnético; dispositivo conversor compreendendo um estágio retificador (210) e um estágio de filtragem (212) transformando o campo magnético captado pelo mesmo em voltagem de fornecimento de energia CC (<MU>d<MV>); e dispositivo de transmissão/recepção de dados, o dispositivo de recepção incluindo meios (218) para desmodular a amplitude do sinal captado pela bobina, o referido dispositivo desmodulador de amplitude operando no sinal (<MU>b<MV>) enviado pelos estágios de retificação e de filtragem. Cada uma das referidas bobinas (102, 202) forma uma porção de um circuito ressonante sintonizado (106, 208) irradiando o campo em espaço vazio. A modulação de amplitude é modulação em baixa profundidade, com uma proporção de modulação que é tipicamente inferior ou igual a 50%.
