发明名称 DESENSITIZING APPARATUS FOR ELECTROMAGNETIC ARTICLE SURVEILLANCE SYSTEM
摘要 A desensitizing apparatus (30) for magnetizing a desensitizable marker (3 8) used with an electromagnetic article surveillance system. The apparatus includes a rectangular, non-metallic plate (50) positioned so that its length is perpendicular to a likely direction of travel (68) of the marker to be magnetized. A row o f X- shaped arrays (60) of elongated magnets (52, 54, 56) is embedded on the plat e. A marker passing over the row of magnets will be desensitized regardless of its orientation or direction of travel over the magnets.
