Abstract

"OSCILADOR DE RELAXAçãO PARA TRANSPONDER". Um oscilador de relaxação para um transponder (102, 200, 400), capaz de medir um ou mais parâmetros (por exemplo, temperatura, pressão) em um objeto (por exemplo, um pneu 104) e transmitir um fluxo de dados (Figuras 3C, 4B) para uma leitora / interrogador 106 externa. O transponder opera, tipicamente, em um modo passivo, derivando a sua energia (Vxx, Vcc, Vdd) de um sinal de interrogação RF recebido por um sistema de antena (210, 410), mas pode também operar em um modo ativo energizado por bateria. O transponder inclui memória (238, 438) para armazenar as medidas, dados de calibração, ajustes de ordenamento programáveis (436b), ID do transponder e assemelhados. As leituras de medida (N~ T~, N~ p~) compreendem a contagem das oscilações de um sinal de medida (Fosc') durante uma janela de tempo fixa (t~ W~, t~ T~, t~ p~) . O sinal de medida é gerado por um oscilador de relaxação (252, 312, 452, 512) acionado por carga e descarga alternadas dos capacitores de medida (C~ FX~, C~ P~), em que a taxa de carga do capacitor é uma função de corrente (uma corrente de medida I (T) B, que pode ser indicativa de temperatura), e de capacitância (que pode ser indicativa de pressão).
