Examples of deactivation devices include those sold under the trademarks Speed Station� and Rapid Pad� commercially available from the assignee, Sensormatic Electronics Corporation of Boca Raton, Fla. The Rapid Pad� deactivator, which generates a magnetic field when a tag is detected, has a single or planar coil disposed horizontally within a housing. Deactivation occurs when the tag is detected moving horizontally across in a coplanar disposition and within a four inch proximity of the top surface of the housing located on top of a check-out counter.
The Speed Station� deactivator has a housing with six coils orthogonally positioned therein to form a "bucket-like" configuration. An employee inserts an article or plurality of articles into the open side of the bucket. The employee then deactivates the inserted articles by manually triggering the deactivator.
The Speed Station� deactivator includes six coils divided into three coil pairs, which are disposed about the bucket in respective x, y and z-axis planes. The coils of each coil pair are positioned parallel to one another and the coil pairs are driven one pair at a time in sequence resulting in a three step sequence for deactivation of an EAS tag. Because the coils are in three planes, orientation of the tag with respect to the coils is not required, however, the tag needs to be inserted inside the cavity of the bucket to permit deactivation.
The above-described deactivators are limited in their usefulness in that the deactivation zone or area for deactivating the EAS tags is restricted to the area and height of the planar coil configuration of each deactivator. For example, when using the Rapid Pad� deactivator, the deactivation zone for deactivating a tag exists only in a horizontal or coplanar direction and within a four inch proximity from the top surface of the housing of the deactivator. This requires the operator to make sure that the tag is within close proximity to the surface of the Rapid Pad� deactivator to ensure that the tag is deactivated. With respect to the Speed Station� deactivator, its deactivation zone exists only inside of its "bucket" configuration, thus requiring the tag to be inserted therein.
In the embodiment of the invention to be disclosed hereinafter, the first and second coil parts of the deactivating coil are separate and independent coils located in a housing. The first coil part is positioned in a side section of the housing and forms an angle in the range of 45� to 135� with respect to the plane of the second coil part located in an adjacent bottom section of the housing.
Preferably, the first deactivating coil 14 is positioned so that its plane is at an angle in the range of 45� to 135� with respect to the plane of the second deactivating coil 16. As illustrated in FIG. 1, the coils 14 and 16 are positioned adjacent to one another, in approximately orthogonal or 90� relation. The coils 14 and 16, however, are not limited to this angular range, but can be positioned at a variety of different angles depending on the shape of the deactivation zone desired to be formed by the deactivation device 10.
As shown in FIG. 3, the tag 9 comprises a magnetostrictive amorphous element 9A contained in an elongated housing 9B in proximity to a control element 9C which can be comprised of a biasing magnetizable material. Tags of this type are commercially available from assignee, Sensormatic Electronics Corporation of Boca Raton, Fla. under the trademark Ultra*Max�. The characteristics and operation of tags like the deactivatable tag 9 is further described in U.S. Pat. No. 4,510,489 which is incorporated by reference herein.
As can be seen in FIG. 6, the coil 100 is bent to form a "bracket" or "L" shape where the side section 102 of the coil 100 is bent at least at a 45� angle with respect to the bottom section 104. The energizing unit 2 energizes the bent deactivating coil 100 to provide a deactivation zone 20, as shown in FIG. 7, similar to that provided by the first and second deactivating coils 14 and 16 of FIGS. 1 and 2. The increased height and area coverage provided by the side and bottom sections 102 and 104 of the bent deactivating coil 100 thus help to produce a larger deactivation zone to permit easier deactivation of the tag 9.
