Abstract

"SINCRONIZAçãO DE AUTO AJUSTE DE FASE PARA SISTEMAS DE VIGILâNCIA DE ARTIGO ELETRôNICO PULSADOS". Sincronização automática de sistemas de vigilância de artigo eletrônico (EAS) operando na proximidade um do outro é fornecida. O sistema e método envolve determinar a fonte de um sinal detectado (1-11), e ajustando automaticamente a fase de um transmissor de EAS pulsado (13-17) por amostragem de amplitude de um sinal recebido para detectar a borda dianteira de um pulso de transmissão interferente, e calcular um retardo correspondente para sincronizar o transmissor atual com o transmissor interferente. A detecção de etiquetas de EAS colocada muito perto da zona de interrogação de transmissor de EAS (20) é também fornecida. Um alarme pode ser implementado arpa indicar as etiquetas de EAS detectadas que são colocadas muito próximas da zona de interrogação.
BRPI0303331A 2002-03-11 2003-03-11 método e sistema para determinar se um sinal detectado por um receptor de um transmissor de sistema de vigilância de artigo eletrônico pulsado é devido a um transmissor interferente ou uma identificação de vigilância de artigo eletrônico BRPI0303331B1 (pt)
