    摘要： Systems and methods for operating a security tag. The methods comprise: receiving a first wireless signal using a receive circuit of the security tag; inducing a voltage in the receive circuit of the security tag while the first wireless signal is being received; performing operations by a controller to selectively close a switch while the voltage is being induced in the circuit; causing a release of a mechanical component of the security tag by allowing energy to flow from the receive circuit to the mechanical component when the switch is closed; and performing operations by the controller to prevent damage to the mechanical component as a result of the security tag being a certain distance from an external device.

    摘要： A system is provided. The system includes a detacher. The detacher includes a field source. The field source is arranged to provide a first magnetic field when power is applied to the field source. The detacher further includes a magnet arranged to provide a second magnetic field. The magnet is movable from a non-detach position to a detach position when exposed to the first magnetic field. The second magnetic field is arranged to unlock a security tag when the magnet is at the detach location. The system further includes an activation device. The activation device includes a processor configured to trigger power to be supplied to the field source.

    摘要： A deactivator device for a mobile Point of Sale (mPOS) systems includes a pair of spaced apart, fixed position electromagnets positioned and configured such that magnetic fields generated by the electromagnets aid one another to form a combined magnetic field; a battery; a capacitor; and an electronics assembly including a microcontroller configured to control storage of energy from the battery in the capacitor and to selectively provide a deactivation or activation pulse from the capacitor to the electromagnets. The components may be positioned in a housing configured for attachment to a mPOS mobile device.

    摘要： A device for deactivating magnetomechanical EAS markers includes a storage capacitor and a coil for generating a deactivation field. A bridge arrangement of four switches interconnects the coil with the storage capacitor and with circuit ground. The switches are controlled to apply a train of DC pulses to the coil such that the pulses have alternating polarities and decreasing amplitudes.

    摘要： Methods, systems and devices for providing an interrogation signal from a handheld deactivation device for identifying a security tag. Identifying the security tag includes initiating an interrogation signal, wherein the interrogation signal includes plurality of transmission bursts and a plurality of random time periods to wait between transmission bursts such that a unique time period elapses between each of the plurality of transmission bursts. The interrogation signal is then transmitted by transmitting each of the plurality of transmission bursts for a portion of a duty cycle and interrupting transmission between each of the plurality of transmission bursts for one of the plurality of random time periods such that a unique and random time period elapses between each of the plurality of transmission bursts. The period transmission of the interrogation signal provides for improved battery life of a handheld scanning and deactivation device.
