Abstract: A system may include a security controller communicatively coupled with pedestals having a first set of antennas and a second set of antennas spaced from the first set of antennas to form an interrogation zone. The security controller may be configured to alternate transmission and reception of interrogation signals between the first set of antennas and the second set of antennas. The security controller may be configured to determine whether a metal object is detected in the interrogation zone in response to the reception of the interrogation signals by the second set of antennas or by the first set of antennas. The security controller may be configured to generate and send an alarm signal in response to the metal object being detected in the interrogation zone.

Abstract: Aspects of the present disclosure include methods, systems, and non-transitory computer readable media for transmitting at least one incident radio frequency identification (RFID) signal to a RFID tag attached to a merchandize item, receiving at least one reflected RFID signal from the RFID tag, determining a frequency response of the RFID tag based on the at least one reflected RFID signal, comparing the frequency response to a plurality of baseline frequency responses, and determining a state of the RFID tag based on the comparing.

Abstract: An EAS system first transmits, over a time, a radio frequency identification (RFID) interrogation signal into an RFID interrogation zone of an EAS system. The system then first receives at least one RFID response signal from a first RFID tag of the system responding to the interrogation signal. The system second transmits, over a second time overlapping at least in part with the first time, a non-RFID RF signal into a second zone. The second zone and the RFID interrogation zone overlap to form a zone of interest. The system second receives, from the first RFID tag, an indication that the first RFID tag received the second transmission. The system determines, based on receiving both the RFID response signal from a first RFID tag and the indication that the first RFID tag received the second transmission, that the first RFID tag is in the zone of interest.

Abstract: A system may be configured to perform object counting in high volume traffic. In some aspects, the system may detect a candidate object within the region of interest in a current video frame, and determine that the candidate object is a detected object based at least in part on comparing an attribute value of the candidate object to historic attribute information determined during a plurality of previous video frames. Further, the system may determine track information based on the detected object and determine an object count representing a number of the objects that have entered the region of interest and/or a number of the objects that have exited the region of interest.

Abstract: An RFID portal of an EAS system first interrogates a first zone extending into a controlled area beyond a threshold distance from an interrogating antenna of the portal. The portal defines an exit from the controlled area, the threshold distance being less than a width of the exit. The portal first detects, in response to the first interrogating, a first response of a particular RFID tag. The portal second interrogate, subsequent to the first detecting, in a second zone extending into the controlled area at least to the threshold distance. The portal second detects, in response to the second interrogating, at least one second response of the particular RFID tag indicating a received signal strength of the second interrogating at the particular RFID tag corresponding to a distance from an interrogating antenna of the portal less than the threshold distance. The EAS system alarms in response to the second detecting.

Abstract: A system may be configured to perform object counting in high volume traffic. In some aspects, the system may determine object detection information defining an absence of an object within the region of interest in a current video frame, and determine that a location associated with the object is within a placeholder-eligible area within the region of interest based on first tracker information determined in a previous video frame. Further, the system may determine second tracker information including a bounding representation for the object based at least in part on the location and object detection information, and determine, based on the second tracker information, an object count representing a number of the objects that have entered the region of interest and/or a number of the objects that have exited the region of interest.

Abstract: Techniques for distinguishing objects (e.g., an individual or an individual pushing a shopping cart) are disclosed. An object is detected in images of a scene. A height map is generated from the images, and the object is represented as height values in the height map. Based on height properties associated with another object, it is determined whether the other object is associated with the object. If so determined, the objects are classified separately.

Abstract: Systems and methods for operating a security tag. The methods comprise: causing a plunger of the security tag to engage a latch of the security tag; preventing, by an anti-defeat structure of the security tag, a disengagement between the plunger and the latch when an impact force is applied to the security tag; and allowing, by the anti-defeat structure, the plunger to disengage the latch when a magnetic field is applied to the security tag.

Abstract: Aspects of the present disclosure include methods, systems, and non-transitory computer readable media for receiving a confirmation signal to unlock the security tag from being locked to a merchandise, transmitting a RFID signal to the RFID device associated with the security tag to enable a controller to receive a release signal used to unlock the security tag from the merchandise, and transmitting the release signal to the controller to unlock the security tag from the merchandise.

Abstract: A radio frequency identification (RFID) system first interrogates, in a first mode, one or more particular target zones of the plurality of target zones including a given target zone. Each particular target zone is interrogated with one of the antennas at a time at a first power for the particular target zone. The RFID system monitors, upon first interrogating, for a trigger condition to occur. In response to the trigger condition not occurring, the RFID system continues the first interrogation in the first mode. In response to the trigger condition occurring, the RFID system second interrogates the given target zone in a second mode at a second power with a plurality of the antennas. The second power for the given target zone is greater in an aggregate across the second interrogating antennas than the first power for the given target zone.
