Norman Hansen - Highland Beach FL, US
Gary Mark Shafer - Boca Raton FL, US

Assignee:

Sensormatic Electronics Corporation - Boca Raton FL

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.

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.

Assignee:

Sensormatic Electronics Corporation - Boca Raton FL

International Classification:

G08B 1314

US Classification:

3405721

Abstract:

A magnetostrictive element for use in a magnetomechanical marker has a resonant frequency characteristic that is at a minimum at a bias field level corresponding to the operating point of the magnetomechanical marker. The magnetostrictive element has a magnetomechanical coupling factor k in the range 0. 28 to 0. 4 at the operating point. The magnetostrictive element is formed by applying current-annealing to an iron-nickel-cobalt based amorphous metal ribbon, or by cross-field annealing an iron-nickel-cobalt alloy that includes a few percent chromium and/or niobium.

Appl. No.:

9/015236

Inventors:

Sylvie R. Morin - Deerfield Beach FL
Wing K. Ho - Boynton Beach FL
Kevin R. Coffey - Fremont CA

Assignee:

Sensormatic Electronics Corporation - Boca Raton FL

International Classification:

G08B 1314

US Classification:

3405721

Abstract:

A harmonic-type electronic article surveillance marker includes a thin, elongated active element and flux concentrators provided at the ends of the active element. The flux concentrators have magnetic anisotropies that are oriented perpendicular to the length of the active element. The orientation of the magnetic anisotropies and the anisotropy field of the flux concentrators stabilize the switching threshold of the marker. The switching threshold level can be controlled by varying parameters such as the angle of the magnetic anisotropies relative to the length of the active element, the strength of the anisotropy field of the magnetic anisotropies, and the geometry of the active element and the flux concentrators.

Assignee:

Sensormatic Electronics Corp. - Deerfield Beach FL

International Classification:

G08B 1324

US Classification:

340551

Abstract:

A marker for use in an electronic article surveillance system in which the marker comprises a magnetically soft component and exhibits a pinned wall hysteresis characteristic with a step change in flux at a threshold value of applied field and in which the marker further comprises a magnetically hard or semi-hard component integral with the soft component and whose magnetic state can be switched between activating and deactivating states to switch the marker between active and deactive states.

US Classification:

3405728, 4272082

Abstract:

A security system tag. The security system tag includes a housing. The security system tag further includes an electronic article surveillance, EAS, element in which the EAS element is arranged to emit a detectable signal when introduced to an interrogation signal. The security system tag further includes a metal element in which the metal element is adapted to be heated. The security system tag further includes a first reversible adhesive proximate the metal element in which at least a portion of the first reversible adhesive de-bonds when thermally affected by the metal element when the metal element is heated.
