摘要： A device for deactivating a magnetomechanical EAS marker includes two coils and an energizing circuit for alternately driving the coils. One coil is driven for one cycle of an alternating power signal, and then the other coil is driven for one cycle, and this sequence is repeated. The driving signal is switched from one coil to the other at a point in time which corresponds to a zero crossing of the current level of the driving signal.

摘要： A two-dimensional array of magnetomechanical markers is adhered to a continuous web. A magnetizer element is scanned across the web to magnetize the bias elements in a group of the markers with a first polarity, thereby activating the group of markers. The web is then advanced and the magnetizer is scanned across the web in an opposite direction to the previous scan, to magnetize the bias elements of a second group of the markers with a second polarity, thereby activating the second group of markers. The web is slit in a longitudinal direction to produce web-strips each carrying a column of the activated markers. The web-strips are rolled to form marker roll assemblies each having about half the bias elements magnetized with a first polarity and the remaining bias elements magnetized with an opposite polarity. The roll of activated markers forms no more than a minimal "leakage" magnetic field.

摘要： A material used to form a biasing element for a magnetomechanical EAS marker has a coercivity that is lower than the coercivity of biasing elements used in conventional magnetomechanical markers. The marker formed with the low coercivity material can be deactivated by applying an AC magnetic field at a level that is lower than is required for deactivation of conventional markers. The marker with the low coercivity bias element can also be deactivated when at a greater distance from a deactivation device than was previously practical.
