摘要： An electronic article surveillance tag features a spindle assembly which anchors and retains a set of ball bearings which are used to clutch and retain the shaft of a tack (24). The spindle (16) features an operational tab which may be contacted by the appropriate probe to turn the spindle (16) about a central axis. The spindle (16) is seated in a retaining means with a graduated lip around the perimeter. The turning of the spindle (16) serves to raise a portion of the spindle (16) from the retaining means, loosening the ball bearing grip on the shaft of the tack. The electronic article surveillance tga may be used with either a smoothed or grooved tack (24) shaft and may be operated by either mechanical probe actuation or by the use of a magnetic detachment means applied to the spindle (16).

摘要： A deactivator for deactivating label-style EAS devices is claimed. A preferred embodiment employs a microprocessor unit to control two transceiver coils, and a deactivation coil in series with a capacitor. The two transceiver coils are essentially two flat figure eights arranged concentrically but rotated through some angle with respect to each other. The transceiver coils are operated alternatively, first transmitting an interrogation signal and then listening for a response. When an EAS device is detected, the microprocessor unit drives the capacitor and deactivation coil at the system's resonant frequency to generate a high amplitude magnetic field then shifts the frequency of the driving current away from the resonant frequency to attenuate the magnetic field. A field sensor or current sensor provides feedback to the microprocessor to determine the resonant frequency of the system during a frequency sweep.

摘要翻译：要求用于停用标签式EAS设备的去激活器。优选实施例采用微处理器单元来控制两个收发器线圈和与电容器串联的去激活线圈。两个收发器线圈基本上是两个扁平的图形，其同心地布置，但是相对于彼此旋转一定角度。收发器线圈交替操作，首先发送询问信号，然后收听响应。当检测到EAS设备时，微处理器单元以系统谐振频率驱动电容器和去激活线圈，以产生高振幅磁场，然后将驱动电流的频率偏离谐振频率以衰减磁场。现场传感器或电流传感器向微处理器提供反馈，以确定频率扫描期间系统的谐振频率。

摘要： An electronic article surveillance system utilizing infrared communication is disclosed wherein added security is obtained by using dynamic passcode protection. The system includes tags, deactivators, a base control system and perhaps one or more remote management stations. Each tag, base station, remote station and deactivator includes an accurate clock generator, a microprocessor, infrared communication capabilities, and machine readable instructions encoded for performing an algorithm for generating multiple passcodes. At a specified time, each active tag possesses a changeable passcode. The base station further includes infrared communication capabilities with an infrared communication path between each tag and each base station, the path enabling interchange of information between each tag and each base station. Each tag replaces the passcode at a specified interval, or at a specified point in time.
