Patent number: 9070265Abstract: Systems (100) and methods (1500) for operating a security tag (132) of an Electronic Article Surveillance (“EAS”) system. The methods involving: attaching a clip (210) to a curved sidewall (202) of an article (102) such that a central body (304) of the security tag is vertically aligned with a central axis of the curved sidewall; maintaining the vertical alignment by locating first and second flanges (306, 502) of the security tag against respective opposing surface areas of the curved sidewall; wrapping a securement member (212) of the security tag around an elongate structure (204) of the article which is offset from the curved sidewall in at least one direction and which protrudes away from a main body (218) of the article; and locking the securement member in a position wrapped around the elongate structure of the article using a mechanical locking mechanism (214) of the security tag.Type: GrantFiled: August 21, 2013Date of Patent: June 30, 2015Assignee: Tyco Fire & Security GmbHInventors: Danhui Luo, John C.

Publication number: 20140077954Abstract: Systems (100) and methods (1300) for operating a security tag (132). The methods involve: slidingly coupling a first engagement member (212) of the security tag to a first sidewall (208) forming a first right angle with a base (220) of an article; and extending a securement member (218) of the security tag across an exterior surface of the base of the article. A second engagement member (210) of the security tag is slidingly coupled to a second sidewall (206) opposed from the first sidewall and forming a second right angle with the base of the article. A length of the securement member is then decreased so as to place the securement member in a tensioned position whereby the security tag is secured to the article. The securement member can be locked in the tensioned position using a mechanical locking mechanism (222) of the security tag.Type: ApplicationFiled: September 19, 2013Publication date: March 20, 2014Applicant: Tyco Fire & Security GmbHInventors: DANHUI LUO, John C.

Publication number: 20100095495Abstract: A theft-deterrent device (10) for application to an article to be protected includes first (20) and second (30) components adapted for locking engagement to secure the article therebetween, with a fragile vile (60) disposed within the first component containing a detrimental substance which would damage the article in the event the vial is fractured. A pin (15) protruding from the first component has a first end secured to the vial using a suitable attachment structure. The attachment structure provides an aperture which surrounds a portion of the “vial in a closely engaged arrangement, and also serves to rupture the vial and release the detrimental substance if unauthorized removal is attempted. The pin and the attachment structure can be integrally formed, or alternatively the attachment structure can be formed as a separate piece and attached to the pin.Type: ApplicationFiled: February 20, 2008Publication date: April 22, 2010Inventors: Thang Tat Nguyen, Dale W.

Patent number: 6373390Abstract: 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. An abutment and spring gate mechanism is placed within the arcuate channel to prevent a relatively rigid wire formed into an arcuate shape from being used to release the attaching assembly part.Type: GrantFiled: August 8, 2000Date of Patent: April 16, 2002Assignee: Sensormatic Electronics CorporationInventors: Dennis L. Hogan, Thang Tat Nguyen, Sergio M. Perez, Andrew Proulx
