Abstract

método e sistema para redução do efeito da interferência em sistemas integrados de vigilância de artigo eletrônico/detecção de metal. a invenção se refere a um sistema integrado de detecção de metal/vigilância de artigo eletrônico ('eas'). o sistema inclui um transmissor operável para transmitir um sinal de interrogação de eas, onde o sinal de interrogação de eas estabelece uma zona de interrogação e é usado para detectar marcadores de eas e objetos de metal dentro da zona de interrogação. o sinal de interrogação de eas é transmitido em uma primeira frequência durante um ciclo de detecção de eas e em uma segunda frequência durante um ciclo de detecção do metal. o sistema inclui um receptor operável para detectar um sinal recebido de um marcador eas, e um módulo detector de metal operável para detectar um objeto de metal em proximidade ao sistema integrado de detecção de metal/eas, onde o módulo detector de metal inclui um filtro sintonizado para remover substancialmente a primeira frequência de transmissão.
