Abstract

"DISPOSITIVO DE DESATIVAçãO DE VáRIOS USOS PARA MARCADORES DE VIGILâNCIA DE ARTIGOS ELETRôNICOS" Um dispositivo de desativação único (10) é usado para desativar tanto marcadores EAS do tipo harmônico quanto marcadores EAS do tipo magnetomecânico. O dispositivo de desativação inclui uma carcaça (12), um ímã permanente (14) e uma bobina (16) dispostos dentro da carcaça. A bobina é circular e é disposta concentricamente com o, e fora do, ímã permanente. O ímã permanente forma um campo magnético DC para desativar um marcador do tipo harmônico pela magnetização de componentes de controle dele. A bobina é acionada para gerar um campo magnético AC que desativa o marcador do tipo magnetomecânico pela desmagnetização de um componente de controle dele. A amplitude máxima do campo magnético AC é mais baixa que o nível do campo magnético DC e está substancialmente abaixo da coercitividade dos componentes de controle do marcador do tipo harmônico. A coercitividade do componente de controle do marcador do tipo magnetomecânico é baixa o bastante para ser desmagnetizada pelo campo magnético AC.
