Larry Speciale - Loxahatchee FL

Assignee:

Sensormatic Electronics Corporation - Boca Raton FL

International Classification:

G08B 1314

US Classification:

3405723, 3405726

Abstract:

A magnetomechanical EAS tag having a bias magnet made of a high magnetostrictive material so that stress, which is a result of ordinary use of an article incorporating the tag, demagnetizes the bias rending the EAS tag inactive is provided. In an alternate embodiment a mechanical mechanism is incorporated with a conventional EAS tag to deactivate the tag upon ordinary use of an article to which the tag is associated. In yet another embodiment, a combination of the bias magnet made of a high magnetostrictive material and a mechanical deactivation mechanism is used to deactivate an EAS tag during ordinary use of an article to which the tag is associated.

International Classification:

G08B 13/14

US Classification:

3405729, 3405728

Abstract:

A reusable EAS tag that is detachable from an article by placing the EAS tag in proximity to a detaching device is provided. The tag includes an energy coupler, a micro-actuator, and a clamping mechanism. The detaching device transmits a signal to the EAS tag to signal detachment, which is received by the energy coupler. The energy coupler converts the energy from the transmitted signal to electrical energy and delivers the electrical energy to the actuator. The actuator converts the electrical energy to mechanical energy to actuate the clamping mechanism and release the tag's locking or clamping mechanism for removal of the tag from the article to which it is attached.

Inventors:

Wing K. Ho - Boynton Beach FL, US

Assignee:

Sensormatic Electronics Corporation - Boca Raton FL

International Classification:

E05B 65/00

US Classification:

70 571, 247041

Abstract:

An identification/surveillance device including a tag portion and a tack. The tack includes a button and a pin having a dull end and a sharp end. The identification/surveillance device is secured to an article to be identified/surveilled by inserting the pin through the article and engaging the pin with the tag portion. The dull end of the pin is releasably engaged with either the button or the tag portion such that when the identification/surveillance device is removed from the article the sharp end of the pin remains engaged with either the tag portion or the button and only the dull end of the pin is exposed.

Abstract:

A security tag and system for securing objects, the system and security tag includes an acousto magnetic (“AM”) electronic article surveillance (“EAS”) component that has a housing with a defined surface area. The housing of the EAS component includes a perimeter boundary that defines an EAS component plane. The system and security tag further include a radio frequency identification (“RFID”) component that includes an integrated circuit and a dipole antenna defining an RFID component plane that is substantially coplanar with the EAS component plane. The integrated circuit and the dipole antenna are positioned externally along the perimeter boundary of the EAS component.

International Classification:

G08B 13/14

US Classification:

3405729

Abstract:

A magnetic detacher has a core magnet and a ring magnet. The core magnet has a body with a top and bottom surface, and produces a first magnetic field. The ring magnet defines a cavity. The ring magnet has a body with a top and bottom and produces a second magnetic field. The ring magnet is axially aligned with the core magnet such that the first magnetic field opposes the second magnetic field along the bodies and enhances it within the cavity. The top surface of the core magnet is separated from the bottom surface of the ring magnet by a predetermined distance thereby producing a resultant magnetic field having a first resultant field strength at a specific position greater than a second resultant field strength produced at the same position when the top surface of the core magnet abuts the bottom surface of the ring magnet.
