Abstract
A robust tag. The robust tag may include a body section, at least one movable latching member disposed within the body section, at least one attachment structure receivable within the body and selectively engageable to the at least one latching member; and at least one responsive member disposed within the body and in cooperative arrangement with the at least one latching member. Upon the application of a signal to at least one drive position on the body section, the responsive member generates a flexural wave that induces a movement of the at least one latching member, so as to disengage the at least one latching member from the at least one attachment structure.
Claims20
An electronic article surveillance system, comprising:
- an robust tag having at least one latching mechanism in selective engagement to at least one attachment structure, the at least one latch mechanism being in cooperative arrangement with at least one acoustically responsive member such that a flexural wave generated by the acoustically responsive member induces a movement of the at least one latching mechanism;
- and
- a tag detaching device adapted to receive the electronic article surveillance tag and having a signal generator for emitting a signal at a frequency to which the at least one responsive member is responsive.
An electronic article surveillance system, comprising:
- an electronic article surveillance tag having at least one responsive member disposed therein;
- and
- a tag detaching device adapted to receive the electronic article surveillance tag and having at least one ultrasonic driver disposed therein;
- wherein, when the electronic article tag is received by the tag detaching device, the at least one ultrasonic driver couples to the at least one resonant member so as to form at least one ultrasonic motor.
A robust tag, comprising:
- a body section;
- at least one movable latching member disposed within the body section;
- at least one attachment structure receivable within the body and selectively engageable to the at least one latching member;
- and
- at least one responsive member disposed within the body and in cooperative arrangement with the at least one latching member,
- wherein, upon the application of a signal to at least one drive position on the body section, the responsive member generates a flexural wave that induces a movement of the at least one latching member, so as to disengage the at least one latching member from the at least one attachment structure.
