Abstract: The present aspects include a magnetic detacher including a housing having a wall that defines a nest configured to receive a security tag; a gate member and an actuator configured to move the gate member between a closed position and an open position, wherein the gate member in the closed position blocks the nest, and in the open position allows access to the nest; a magnet positioned on an opposite side of the housing relative to the nest and adjacent to the nest, the magnet having a field in an area of the nest sufficient to unlock a magnetic lock of the security tag; and a processor in communication with the actuator and with a transaction system, wherein the processor is configured to control the actuator to move the gate member from the closed position to the open position based on receipt of an unlock signal from the transaction system.

Abstract: The present aspects include a method of detaching a security tag from an article, including receiving, at a detacher device, an unlock signal from a transaction system. The detacher device includes a housing having a nest configured to receive a security tag, a gate assembly including a gate member movable between a closed position that blocks the nest and an open position, and a magnet positioned on an opposite the nest and having a magnetic flux sufficient to unlock a magnetic lock of the security tag. The method further includes moving the gate member from the closed position to the open position based on receipt of the unlock signal, receiving the security tag in the nest, and unlocking the magnetic lock of the security tag to allow the security tag to be detached from the article.

Abstract: In an aspect, the present disclosure includes a system for detecting metal foil using millimeter wave (mmWave) for retail applications. The system comprises one or more pedestals positioned to define an exit portal leading to a point of exit, one or more security tag readers, fixedly positioned with the one or more pedestals, configured to read data from a security tag passing through the exit portal and one or more mmWave receivers, fixedly positioned near the point of exit, configured to receive one or more reflected mmWave beams from metal foil, wherein the detection of metal foil results in an alert message.

Abstract: In an aspect, the present disclosure includes a system for interrogating a person exiting a store. The system comprises one or more pedestals positioned to define an exit portal leading to a point of exit, one or more mmWave sensors, fixedly positioned near the point of exit, configured to receive one or more reflected mmWave beams from a person approaching the point of exit and triggering an interrogation of a security tag; and one or more security tag readers, fixedly positioned with the one or more pedestals, configured to read data from the security tag passing through the exit portal.

Abstract: Systems and methods for operating an Electronic Article Surveillance (“EAS”) system. The method comprising: receiving, by an electronic device, a synchronization signal transmitted from a remote Wireless Device Manager (“WDM”); performing first transmit and receive operations at the electronic device that are synchronized in accordance with the remote WDM's AC power line zero crossing specified by the synchronization signal; detecting when the synchronization signal is no longer being received by the electronic device; and performing second transmit and receive operations at the electronic device that are synchronized in accordance with the electronic device's local AC power line zero crossing, when the synchronization signal has not been received by the electronic device for a specified period of time.

Abstract: A people counting system and method for the automatic reconfiguration of a failed people counting sensor device in a people counting system. The system includes a plurality of addressable people counting sensor devices defining a cluster having a master device in communication with at least one slave device, each of the master device and the slave devices having a corresponding Media Access Control (“MAC”) address. The master device is adapted to sequentially transmit power-on commands to each of the slave devices, assign a different node address to each of the slave devices, receive an association of the MAC address of the master device to the node address and MAC address of each of the slave devices to form a cluster configuration, store the cluster configuration as a cluster configuration table, and replicate the cluster configuration table to the slave devices. A dynamic host configuration protocol (DHCP) server assigns an IP public address to the master device.
