Abstract:
A mobile tag reader that may be configured to wirelessly communicate with a security tag is provided. The mobile tag reader may include a position estimator, which includes processing circuitry configured to receive information indicative of at least a first read event associated with a first antenna beam pattern and a second read event associated with a second antenna beam pattern emitted by the mobile tag reader. The processing circuitry may be further configured to identify an overlap area between at least the first antenna beam pattern and the second antenna beam pattern. The processing circuitry may be further configured to determine an estimated location of the security tag based on the overlap area.
Abstract:
In one embodiment, a security includes a planar EAS component having opposing first and second surfaces; and an adhesive layer adhered to the second surface of the planar EAS component and configured to adhere the planar EAS component to an object; wherein the first surface of the planar EAS component comprises a perforation line defining a closed interior portion of the planar EAS component and an exterior portion of the planar EAS component; and wherein the adhesive layer has a strength such that, when the adhesive layer is adhered to the object and the exterior portion is peeled away from the object, the planar EAS component tears along the perforation line and the interior portion remains adhered to the object.
Abstract:
A security device is provided including a security lock configured to retain an object when locked, a receiver configured to receive a security code transmission, and processing circuitry configured to transition the security lock between a locked state and unlock permissive state based on receipt of a security code. The security lock may initially be set to the unlock permissive state. At the first instance in which a security code is received, the processing circuitry may transition the security lock to a key permissive mode in which the security lock transitions to a locked state and in response to a subsequent receipt of the security code the security lock transitions to the unlock permissive state.
Abstract:
A security device includes: a housing having a plug receptacle; a spool rotatably coupled to the housing; a locking mechanism having a locked state and an unlocked state, the locked state preventing the spool from rotating in a first direction, and the unlocked state allowing rotation of the spool in the first direction and in a second direction; a plug having an inserted position and a removed position with respect to the plug receptacle, the inserted position maintaining the locking mechanism in the locked state, and the removed position allowing alteration of the locking mechanism from the locked state to the unlocked state; a cable coupled to the spool and to the plug; an alarm circuit which activates an alarm upon sensing discontinuity of the cable and/or the plug moving from the inserted position to the removed position, the alarm circuit coupled to and rotating with the spool.
Abstract:
An antenna device and supports for an antenna. The antenna device includes a plate-like support, having a from, back, and surrounding side face. The surrounding side face has a first groove. The front of the support has at least one second groove. The first antenna cable is located in the first groove and in the second groove. The first and second end regions of the second groove are spaced apart from the surrounding side face. The first end region of the second groove has a first opening to the first groove, and the second end region of the second groove has a second opening to the first groove. The first antenna cable is routed through the first and second openings.
Abstract:
An RFID reader device and an antenna device have a first antenna implemented as a near-field antenna, wherein the first antenna has a first dual strip line. The first antenna has a first strip line and a second strip line. The first strip line and the second strip line may be implemented in the form of open loops. The first strip line may be implemented inside the open loop of the second strip line.
Abstract:
A dual EAS-RFID tag. In one embodiment, the invention can be a tag comprising a substrate having a first surface and a second surface opposite the first surface; an electronic article surveillance (EAS) element comprising an EAS antenna, the EAS antenna on the first surface of the substrate; and a radio frequency identification (RFID) element, the RFID element comprising: a far field antenna on the second surface of the substrate, the far field antenna comprising a first pole portion, a second pole portion, and a connecting portion connecting the first pole portion and the second pole portion; a near field loop antenna on the second surface of the substrate, and an integrated circuit operably coupled to the near field loop antenna; wherein the far field antenna, the near field loop antenna, and the EAS element are located on the substrate so as to be physically isolated from one another.
Abstract:
A security device may include a lanyard, a lanyard retention lock, and connectivity detection circuitry. The lanyard may include a first conductor and a second conductor that form an open circuit due to an insulator being electrically disposed therebetween. The lanyard retention lock may be configured to retain one or more ends of the lanyard to secure the security device to a protected object. The connectivity detection circuitry may be electrically connected to the first conductor and the second conductor. The connectivity detection circuitry may be configured to detect an occurrence of a closed circuit connection between the first conductor and the second conductor due to, for example, physical damage to the insulator, and may be configured to generate an alarm trigger signal in response to detecting the occurrence of the closed circuit connection between the first conductor and the second conductor.
Abstract:
A security device may include an attachment assembly configured to affix the security device to an object, a locking assembly configured to lockably secure the attachment assembly and configured to transition between at least a locked state and an unlocked state, a transformer configured to drive an alarm assembly to generate an alarm, and processing circuitry. The transformer may be further configured to operate as a wireless receiver to receive a remotely transmitted wireless signal. The processing circuitry may be configured to monitor an output of the transformer to determine whether the wireless signal has been received via the transformer, and selectively activate the transformer to drive the alarm assembly to generate the alarm.
Abstract:
A loss prevention device includes a magnetometer and a processor operatively coupled to the magnetometer. The magnetometer is configured to measure intensities and directions of one or more maxima in a magnetic field, the one or more maxima including at least a first maximum from magnetic north of the Earth, wherein a first intensity and a first direction are associated with the first maximum. The processor is configured to ignore the first intensity and the first direction associated with the first maximum and to determine whether the one or more maxima includes a second maximum distinct from the first maximum.
