  • Publication number: 20140077954
    Abstract: 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.

  • Publication number: 20110215156
    Abstract: A security tag incorporating a hybrid clamp that combines an attachment clamp with an RFID component. The attachment clamp is used to secure an item, such as an article of clothing, to the tag. The RFID component, e.g., an RFID antenna, transmits data signals to an RFID reader where the data signals are encoded with information stored about the security tag. By combining the attachment features and RFID features of the security tag in one hybrid clamp, more tag space can be freed up for other components and manufacturing cost savings can be realized.

  • Publication number: 20020124478
    Abstract: A post and beam furniture system includes a plurality of overhead beams, and a plurality of vertical posts having at least one outwardly extending flange with a single slot extending vertically along the end face of the flange. Beam-to-post connectors are attached to the opposite ends of the beams, and are detachably retained in the slots in the posts for mounting the beams on the upper ends of the posts. The furniture system may also include X-shaped posts and Y-shaped posts with slots which create an integrated mounting arrangement for detachably interconnecting the posts and beams in alternative configurations, and mounting accessories at a variety of different locations.
