US Patent:

48689157, Sep 19, 1989

Filed:

Jul 20, 1988

Appl. No.:

7/222335

Inventors:

Philip M. Anderson - Chatham NJ
James E. Kearney - New Hyde Park NY
Michael Suchomel - Mountainside NJ
Jeffrey C. Urbanski - Sparta NJ

Assignee:

Allied Corporation - Morristown NJ

International Classification:

H04Q 100

US Classification:

34082531

Abstract:

A keyless entry system has means for defining an interrogation zone. A marker responsive within the interrogation zone to generate a coded signal cooperates remotely with means for disengaging a locking mechanism upon verification of the coded signal when received.

Filed:

Jun 3, 1982

Appl. No.:

6/384814

Inventors:

Philip M. Anderson - Chatham NJ
James E. Kearney - New Hyde Park NY
Gerald R. Bretts - Livingston NJ

Assignee:

Allied Corporation - Morris Township, Morris County NJ

International Classification:

G08B 1326

US Classification:

340572

Abstract:

A magnetic article surveillance system marker is adapted, when armed, to resonate at preselected frequencies provided by an incident magnetic field applied within an interrogation zone. The marker is a plurality of elongated ductile strips of magnetostrictive ferromagnetic material each of the strips being disposed adjacent to a ferromagnetic element which, upon being magnetized, magnetically biases the strips and arms them to resonate at the preselected frequencies. A substantial change in effective magnetic permeability of the marker at the preselected frequencies provides the marker with signal identity.

International Classification:

H01H 61013

US Classification:

335208

Abstract:

A temperature-sensitive switch is provided with a resilient movable cantilever composed of amorphous ferromagnetic material having a Curie point. The cantilever is adapted to carry a first contact member. A second contact member is disposed adjacent the first contact member for at least intermittently establishing electrical contact with the first contact member. A magnet is associated with and adapted to bias the cantilever to a first position that establishes electrical continuity between the first and second contact members. The cantilever is transformed from a ferromagnetic phase to a paramagnetic phase when its temperature exceeds the Curie point, whereby the cantilever assumes a second position in which the electrical conductivity is interrupted. The switch is lightweight, compact, economical to manufacture and reliable in operation.
