摘要： A method and system for reducing the signal interference effects of metal doors in a metal detection system. The system includes a transmitter operable to transmit an interrogation signal that is used to detect transitory metal objects within the detection region, a receiver operable to receive instantaneous signals that represent electromagnetic field disturbances during operation of the metal detection system and include electromagnetic field disturbances attributed to the movement of metal doors. The system also includes a metal detection module that determines a resulting waveform representing the difference between the instantaneous signals received during operation of the metal detection system and a recorded pattern of signals representing electromagnetic field disturbances caused by a pattern of movement of the metal doors in the detection region when a transitory metallic object is not present. The record pattern is canceled from the resulting waveform leaving only signals from transitory metal objects.

摘要： Systems (100) and methods (600) for detecting a location of an EAS security tag (112). The methods involve: determining a first amplitude of a response signal generated by the EAS security tag and received at a first pedestal (102a), and a second amplitude of the response signal received at a second pedestal (102b); processing the first and second amplitudes to determine whether the EAS security tag resides within a specified distance range of the first or second pedestal, a detection zone of an EAS detection system, or a backfield of the EAS detection system; issuing an alarm when the EAS security tag is determined to reside within the specified distance range of the first/second pedestal or the detection zone of the EAS detection system; and preventing issuance of the alarm when the EAS security tag is determined to reside in the backfield of the EAS detection system.

摘要： Systems (100) and methods (600-800) for adaptively controlling a transmitter field in an Electronic Article Surveillance ("EAS") detection system. The methods comprise: detecting, by at least one first proximity sensor (108a, 108b), a presence of a first person located in proximity to a pedestal (102a, 102b) of the EAS detection system; determining a first distance from the first proximity sensor to the first person; and using the first distance to adaptively control the transmitter field of the EAS detection system.

摘要： Interference in an electronic article surveillance (EAS) system is reduced by transmitting warning pulse at a predetermined time following the EAS marker exciter pulse. The predetermined time and duration of the warning pulse are chosen so that the warning pulse acts upon a noise interference avoidance process in a second non-cooperative EAS unit. More particularly, the warning electromagnetic pulse causes a timing change in a second synchronized electromagnetic exciter pulse produced by the second EAS unit when the second synchronized electromagnetic exciter pulse is concurrent with the first receive interval. This timing change causes the second EAS unit to no longer interfere with the first EAS unit.

摘要： Systems (100) and methods (600-900) for adaptively controlling a transmitter field in an EAS detection system. The methods comprise: detecting the presence of a first person located in proximity to a first pedestal of the EAS detection system using a first proximity sensor disposed on the first pedestal; determining a first distance value representing a distance from the first pedestal to the first person whose presence was previously detected using distance information obtained from the first proximity sensor; using the first distance value to select a criteria for use in determining whether the alarm issuance should be inhibited; and adaptively controlling the alarm issuance if the criteria which was previously selected is met based at least on a first amplitude of a security tag signal received at the first pedestal.

摘要： A metal detection device, system and method are provided. The device includes a receiver that receives a signal pattern representing electromagnetic field disturbances over time caused by movement of metal doors in a detection region. The device further includes a memory in communication with the receiver. The memory stores a recorded signal pattern of a previously received signal pattern and at least one quality criterion. The device further includes a processor in communication with the memory. The processor determines pattern vitals indicating a quality of the received signal pattern. The processor further determines whether the at least one quality criterion is met based at least in part on the pattern vitals. The processor further updates the recorded signal pattern based at least in part on determining whether the at least one quality criterion is met.
