Filed: 2004-04-30
Granted: 2011-09-13
Abstract: A security tag includes a combination of a resonant frequency circuit (10) with an adjacent amplification shield (12) for enhancing output signal amplitude. The amplification shield is located adjacent to the resonant frequency circuit and is preferably in the same or substantially the same plane as the resonant frequency circuit or is in a close, generally parallel plane. In an exemplary embodiment, the resonant frequency circuit includes an inductor electrically coupled to a capacitor. The resonant frequency circuit has a center frequency and is arranged to resonate in response to exposure to electromagnetic energy at or near the center frequency, providing an output signal having an amplitude. The amplification shield is arranged to direct a portion of the electromagnetic energy to the resonant frequency circuit to amplify the amplitude of the output signal from the resonant frequency circuit.

Abstract: Outer (12) and inner (14) inflatable members and a motor assembly including a fan are disposed on a base member (18). Air provided under pressure by the motor assembly including the fan passes through vents in the base member (18) to inflate the inflatable members (12, 14). Flakes (16) are disposed in the space between the inflatable members (12, 14). One vent, larger than the others, provides for the flakes (16) to be lifted upwardly from the base member (18) by the pressurized air. At least another vent in the base member (18) provides for a movement of the flakes (16) by the pressurized air in an annular direction in the space between the inflatable members (12, 14). A  permeable cap (60) disposed on the outer inflatable member (12) limits the pressure in the outer (12) and inner (14) inflatable members to a particular value.
