Abstract
<B>IDENTIFICADOR RFID, LEITORA RFID, E SISTEMA RFID INCLUINDO IDENTIFICADORES COM TAMANHOS DE MEMóRIA DIFERENTES<D> Um método de sincronização para um sistema RFID (10) incluindo identificadores (40-1 a 40-n) tendo tamnhos de memória diferentes, emprega uma convenção onde palavras de sincronismo e bits de sincronismo são armazenadas na memória de identificador (407) entre bits de dados de modo que uma leitora (30) possa prontamente identificar a palavra de sincronismo em um sinal RF (408) transmitido por um identificador (40-1) e modulado em série por repetições do conteúdo da memória de identificador (407). Após identificar a palavra de sincronismo, uma leitora RFID (30) lê bits de dados após a palavra de sincronismo identificar até que uma palavra de sincronismo seguinte seja recebida, enquanto ignora os bits de sincronismo interespaçados entre os bits de dados.
