Abstract

Patente de Invenção: "SISTEMA DE SEGURANçA DE ARTIGOS ELETRôNICOS EMPREGANDO DESLOCAMENTOS DE TEMPOS VARIáVEIS". Um sistema de segurança de artigos eletrônicos de recebimento de pulsos (EAS) 10, para detectar a presença de uma identificação de segurança (42) dentro de uma zona de detecção, é descrito. O sistema EAS inclui um transmissor (20) para irradiar um primeiro sinal eletromagnético na zona de detecção. O primeiro sinal eletromagnético é uma seq³ência dos períodos de tempo dos disparos de RF emitidos durante cada um dos vários intervalos de enquadramento contíguos, em que a duração de cada um dos intervalos de enquadramento é um de vários valores diferentes. O sistema EAS inclui ainda um receptor (24) sincronizado com o transmissor (20), para receber um segundo sinal eletromagnético reirradiado de uma identificação de segurança (42) na zona de detecção, em resposta ao primeiro sinal eletromagnético. O receptor proporciona um sinal de saída, se uma identificação de segurança é detectada. Os valores das várias durações dos intervalos de enquadramento são selecionados para serem diferentes dos valores das durações dos intervalos de enquadramento de outros sistemas EAS, tornando, desse modo, o sistema EAS substancialmente isento de falsos alarmes ou bloqueios provocados pela operação de outros sistemas EAS.
