Abstract
Patente de Invenção:<B>"SUPORTE DE DADOS PARA A RECEPçãO SEM CONTATO DE DADOS E DE ENERGIA, BEM COMO O PROCESSO PARA A OPERAçãO DO MESMO"<D>. Suporte de dados com uma bobina (L) para a recepção sem contato de dados e de energia e para a transmissão sem contato de dados assim como com um circuito lógico (LS) para o processamento e armazenamento dos dados recebidos, demodulados e decodificados, com um primeiro demodulador (DEM100) para a demodulação de sinais modulados ASK100% recebidos, com um segundo demodulador (DEM100) para a demodulação de sinais ASK modulados recebidos com um grau de modulação de menos do que 100%, sendo que o segundo demodulador (DEM10) é excitado pelo primeiro demodulador (DEM100) de tal maneira que ele ao receber uma sinal ASK100% modulado é desativado pelo primeiro demodulador (DEM100).
