Abstract

Patente de Invenção: <B>"MARCADOR MAGNETOMECâNICO EAS (VIGILâNCIA ELETRôNICA DE ARTIGOS) COM POLARIZAçãO REPENTINA"<D>. Material usado para formar um elemento de polarização (16) destinado a um marcador magnetomecânico EAS (10) que apresenta uma coercividade que é mais baixa do que aquela dos elementos de polarização usados nos marcadores magnetomêcanicos convencionais. O marcador (10) formado com o material de baixa coercividade pode ser desativado com a aplicação de um campo magnético CA em um nível que é mais baixo do que o exigido para desativar os marcadores convencionais. O marcador (10) com o elemento de polarização de baixa coercividade (16) pode também ser desativado, quando em uma distância maior a partir de um dispositivo de desativação, do que era a prática anteriormente.Invention Patent: <B> "EAS MAGNETOMECHANICAL MARKER (ELECTRONIC SURVEILLANCE OF ARTICLES) WITH SUDDEN POLARIZATION" <D>. Material used to form a polarization element (16) for an EAS magnetomechanical marker (10) that has a coercivity that is lower than that of the polarization elements used in conventional magnetomechanical markers. The marker (10) formed with the low coercivity material can be deactivated by applying an AC magnetic field at a level that is lower than that required to deactivate conventional markers. The marker (10) with the low coercivity polarization element (16) can also be deactivated, when at a greater distance from a deactivation device, than was previously the practice.
