摘要： An EAS or RFID system including first and second core antenna systems. The first and second antenna systems establish magnetic fields having opposite directions and are positioned so that the fields at least partially cancel outside of an interrogation zone for detecting an EAS or RFID tag. There is also provided an EAS or RFID wherein the magnetic field direction established by a core antenna is varied at certain time intervals to minimize the effects of null zones in the interrogation zone.

摘要： A method for operating a Wearable Access Sensor (“WAS”). The methods comprise: capturing RF energy by the WAS, where the RF energy is emitted within a surrounding environment from equipment disposed at an access point of a restricted area; passing the RF energy through a switch that is normally in a position which provides an electrical connection between an antenna of the WAS and a full wave rectifier of the WAS; performing operations by the WAS to convert the RF energy into direct current for generating electric power; supplying the electric power to an energy storage device of the WAS for charging the energy storage device to a pre-determined voltage level; and supplying power from the energy storage device to a controller of the WAS when a voltage level of the energy storage device is equal to or greater than the pre-determined voltage level.

摘要： Systems and methods for controlling access to a Restricted Area (“RA”). The methods involve: determining whether a person desires to enter RA; checking whether the person is authorized to enter RA using a first unique identifier associated with a wearable access sensor being worn thereby; causing the person's Portable Communication Device (“PCD”) to transmit a second unique identifier and location information useful in determining the PCD's location within a surrounding environment, when a determination is made that the person is authorized to enter RA; using the second unique identifier and location information to confirm that the person is currently located at an access point of RA; and causing actuation of a mechanical actuator to enable the person's entrance into RA when it is determined that the person desires to enter RA, the person is authorized to enter RA, and the person is currently located at the access point of RA.

摘要： A material used to form a biasing element for a magnetomechanical EAS marker has a coercivity that is lower than the coercivity of biasing elements used in conventional magnetomechanical markers. The marker formed with the low coercivity material can be deactivated by applying an AC magnetic field at a level that is lower than is required for deactivation of conventional markers. The marker with the low coercivity bias element can also be deactivated when at a greater distance from a deactivation device than was previously practical.

摘要： A security tag including independent EAS and RFID components disposed in a housing configured for geometric placement of the RFID and EAS components for optimum RFID performance. The EAS component is situated in a first compartment and the RFID component is situated in a second compartment. The RFID component includes a hybrid antenna RFID inlay and an IC chip. The tag housing includes a key structure that minimizes the de-tuning of both the EAS and RFID components by positioning the IC chip such that the IC chip is closer to a first side of the second compartment than the second side of the second compartment when the antenna inlay is inserted within the housing. The housing further includes one or more pins that raise the RFID inlay above the magnetic resonator of the EAS component to further insure optimal RFID read performance.

摘要： A security tag includes an EAS component having a defined surface area, and an RFID component having a defined surface area. The EAS component surface area is configured to at least partially overlap the RFID component surface area. The RFID component includes an antenna which at least partially overlaps the first surface. A substantially planar spacer having a thickness is at least partially disposed between the defined surface areas of the EAS and RFID components. The thickness of the spacer is configured to effect a read range between an RFID reader and the RFID component. The RFID reader is capable of activating the RFID component when the RFID component is within the read range. The antenna has a complex impedance, and the EAS component forms a part of an impedance matching network of the antenna.
