Abstract

Official abstract text for this publication.

Security tag includes a housing and a movable locking element. A latch within the housing is resiliently biased toward the movable locking element and movable responsive to a magnetic field between a locked position and an unlocked position. A guide structure is arranged to constrain movement of the latch. The latch and the guide structure are cooperatively arranged to ensure an engagement that will disrupt a motion trajectory of the latch occurring when the housing is subjected to a physical impact. Consequently, the latch is selectively inhibited from moving fully from the locked position to the unlocked position when the housing is subjected to the physical impact.

First claim

Opening claim text (preview).

What is claimed is: 1. A tamper-resistant security tag comprising: a housing; a locking element movably disposed within the housing; a latch disposed within the housing and movable responsive to application of a magnetic field between a locked position, in which movement of the locking element is prevented by the latch, and an unlocked position, in which movement of the locking element is unrestricted by the latch; a resilient member arranged to resiliently bias the latch in…
