Abstract

"SISTEMA DE IDENTIFICAçãO AUMENTADO" São revelados um método e um sistema de identificação para comunicação entre uma leitora (10) e uma pluralidade de transceptores (1, 2, 3). A leitora (10) possui um transmissor (11) para transmitir um sinal e cada transceptor (1, 2, 3) inclui um receptor para receber o sinal da leitora e um transmissor para gerar um sinal do transceptor. Quando a leitora (10) reconhece um sinal do transceptor a partir de um dos transceptores (1), ela imediatamente emite uma instrução de silêncio, silenciando todos os outros transceptores ativos (2, 3) e passando o controle para o dito transceptor (1), sem a necessidade de um reconhecimento especificamente sincronizado para o dito transceptor de controle (1). A leitora (10) pode emitir uma única instrução de desabilita/acorda que desabilita o transceptor de controle (1) retornando o controle para a leitora (10) e reativando todos os transceptores silenciados (mas não desabilitados) (2,3).
