摘要： A method and system for reducing the signal interference effects of metal doors (20) in a metal detection system (10). The system includes a transmitter (36) operable to transmit an interrogation signal that is used to detect transitory metal objects within the detection region, a receiver (40) 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 (18) 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： A method for detecting metal using an electronic article surveillance ("EAS") system. The EAS system includes a transmitter and a receiver. An EAS interrogation signal is transmitted to establish the interrogation zone. The EAS interrogation signal is used to detect EAS markers and metal objects within the interrogation zone. The EAS signal is received and a metal object present in the interrogation zone is detected during a metal detection cycle. The metal object is detected based upon perturbations in the received EAS interrogation signal. The metal detection cycle is periodically interspersed with at least one EAS detection cycle.

摘要： A system and method for reducing the occurrence of false alarms in metal detection systems and combination EAS/metal detection systems. The system includes a motion sensor mounted on or near an antenna housing, such as an EAS pedestal, at the entrance/exit of a given interrogation zone. The motion sensor detects movement or vibration of the antenna housing. The sensor transmits signals to a controller that determines if the antenna housing has moved a predetermined amount. The system includes a metal detection module that determines if metal objects are proximate the pedestal. If metal objects are detected, a metal detection alarm is enabled. However, if it is determined that the antenna housing is moving or vibrating at least a predetermined amount, the controller inhibits generation of the metal detection alarm signal.

摘要： An integrated electronic article surveillance ("EAS")/metal detection system. The system includes a transmitter operable to transmit an EAS interrogation signal, where the EAS interrogation signal establishes an interrogation zone and is used to detect EAS markers and metal objects within the interrogation zone. The EAS interrogation signal is transmitted at a first frequency during an EAS detection cycle and at a second frequency during a metal detection cycle. The system includes a receiver operable to detect a signal received from an EAS marker, and a metal detector module operable to detect a metal object in proximity to the integrated EAS/metal detection system, where the metal detector module includes a filter tuned to substantially filter out the first transmission frequency.
