摘要:
An EAS tag in which the tag is held to an article by an attaching assembly a part of which is releasably prevented from being withdrawn from the body of the tag. The tag body is provided with an arcuate channel through which an arcuate detacher probe can be guided for releasing the attaching assembly part. A spring clamp provides the releasable preventing function and includes jaws specifically adapted to respond to in-plane torsional forces provided by the arcuate probe which is moved through the arcuate channel by rotation to reach the spring clamp. The tag has improved anti-defeat devices and methods including one or more of the following; a shield to protect the EAS sensor, a shield to protect the releasable spring clamp, a tag self-alarm that alarms upon various unauthorized defeat attempts, an LED to signal an armed condition of the tag alarm, a magnet switch to alarm the tag upon exposure to a relatively strong magnetic field, and a plurality of apertures to decoy the position of the alarm piezo.

Techniques to release a security tag are described. One embodiment may comprise a tag housing, a tack body, and a linear clamp disposed within the tag housing to retain the tack body. The linear clamp may move in a substantially linear direction in response to force to release the tack body from the linear clamp. Other embodiments are described and claimed.

A security device having magnetically actuable locking mechanism for security an optical disc is disclosed. The device includes a detectable security tag secured in a housing having an optical disc receptacle formed as a basin. The housing includes one or more arcuate grooves adjacent to the circular basin. A top cover is sized to fit into the circular basin and is configured to be rotatably mateable with the housing. The top includes arcuate lips extending outwardly therefrom adapted for sliding rotatable engagement with the one or more the arcuate grooves in the housing. Locking the device prevents the top cover from being rotated to a position where the arcuate grooves are fully disengaged with the arcuate lips.

In a device for deterring theft of a protected article, including a pin and clutch respectively embodied in two components that are adapted to be locked together on opposite sides of a portion of the protected article to prevent unauthorized removal of the device from the article, the pin-containing component contains two fragile elongated glass vials that fracture when at least a predetermined pressure is applied thereto, with the vials containing a detrimental substance that would damage an article attached to the device if such substance were to be released from the vial; and the head of the pin includes a breaker element having a wedge-shaped surface of a fiber-loaded-reinforced thermoplastic, (which does not scratch glass), for applying more than the predetermined pressure against the vial in response to the pinhead being moved in response to application to the two components of at least a predetermined threshold separation force, to thereby completely fracture the vials by inducing a high bending stress without prematurely cracking the vials, and to thereby release the substance contained therein before the components are separated by prying or pulling the components apart. A pliable seal is disposed between the breaker element and the vials for preventing the detrimental substance that is released from the fractured vials from entering the head space and for expelling the released detrimental substance through the adjacent opening in response to pressure applied against the seal by the breaker element by the movement of the pinhead that results in the vials being fractured.

A method and apparatus for a hard security tag and detaching device are described. The hard security tag may include a sensor to emit a detectable signal when it is in a monitored surveillance zone. The hard security tag may be attached to an item, such as an article of clothing. The detaching device may detach the hard security tag from the item.
