摘要:
A reusable EAS tag that is detachable from an article by placing the EAS tag in proximity to a detaching device is provided. The tag includes an energy coupler, a micro-actuator, and a clamping mechanism. The detaching device transmits a signal to the EAS tag to signal detachment, which is received by the energy coupler. The energy coupler converts the energy from the transmitted signal to electrical energy and delivers the electrical energy to the actuator. The actuator converts the electrical energy to mechanical energy to actuate the clamping mechanism and release the tag's locking or clamping mechanism for removal of the tag from the article to which it is attached.

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tag in which the tag is held to an article by an attaching assembly a part of which is releasably prevented from being withdrawn from the body of the tag.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. The tag has improved anti-defeat devices and methods including one or more of the following; a shield to protect the EAS sensor, a shield to protect the releasable spring clamp, a tag self-alarm that alarms upon various unauthorized defeat attempts, an LED to signal an armed condition of the tag alarm, a magnet switch to alarm the tag upon exposure to a relatively strong magnetic field, and a plurality of apertures to decoy the position of the alarm piezo.

A device for regulating flow comprises a main valve operating under differential pressure wherein the main valve has a main flow inlet and a main flow outlet. The main flow inlet is equipped with a valve seat over which a main shutter is adjusted in a perpendicular direction to its shuttering plane. The main shutter has a hole on its locking face communicating with a pressure chamber disposed above the main shutter. A secondary control valve regulates small flows through the hole so as to create greater or less pressure within the pressure chamber to close or open the main shutter.

System for detaching an electronic article surveillance (EAS) tag includes a detaching element to selectively unlock a locking element of an EAS tag when the EAS tag is placed in a detachment position. A control system is arranged to cause the detaching element to transition from a deactivated state, in which the tag in the detachment position will remain locked, to an activated state in which the tag is unlocked. This transition will result in beginning or starting a dwell time. The control system is maintains the detaching element in the activated state while awaiting receipt from a user interface of a user manually initiated termination signal. The termination signal indicates a user intention to terminate the dwell time. In response to the termination signal, the control system causes the detaching element to transition from the activated state to a deactivated state.
