Abstract: A system and method for scanning individuals for illicit objects include the ability to scan a wheeled user transport device and an individual being transported thereby for metallic objects and to determine whether an illicit object may be present, without activating an alarm for the user transport device while detecting illicit objects on the individual.

Abstract: A metal detection system for detecting metal within a body cavity of an individual. The metal detection system includes a first metal detector for detecting metal within an anal/vagina body cavity of an individual, and a second metal detector for detecting metal within an oral/facial body cavity of the individual. A chair supports a first detector sensor and a second detector sensor that connects to the first metal detector and the second metal detector, respectively. The system further includes a processor that interconnects with the first and second detectors. The processor connects to a control panel having indicators responsive to a first output signal and second output signal generated upon detection of metal by the first metal detector and the second metal detector, respectively.

Abstract: A walk-through metal detection system with split field generation coils excited in phase to generate an electromagnetic field having a substantially uniform vertical field density. A plurality of vertically distributed receiver coils are also provided, each receiver coil connected to a separate detector circuit for detecting disturbances in the generated field caused by the presence of metal objects. The signals are processed to generate an output signal indicative of the individual metal mass (or masses) of objects detected within the generated electromagnetic field. The output signal is compared to a threshold signal, and if greater than the threshold signal, then a metal object is presumed to be present within the electromagnetic field and an alarm is sounded. A remote control may be used by an operator to adjust the threshold signals. Additional processing of the detector circuit outputs differentiates between a single object of large metal mass and multiple objects of combined metal mass.

Abstract: A walk-through metal detection system with split field generation coils excited in phase to generate an electromagnetic field having a substantially uniform vertical field density. A plurality of receive coils are also provided, each receive coil connected to a separate detector circuit for detecting disturbances in the generated field caused by the presence of metal objects. The signals output from the detector circuits are processed in a first embodiment to generate an output signal indicative of the total metal mass detected within the generated electromagnetic field. In a second embodiment, the signals are processed to generate an output signal indicative of the individual lumped metal mass (or masses) detected within the generated electromagnetic field. The output signal is compared to a threshold signal, and if greater than the threshold signal, then an illicit metal object is presumed to be present within the electromagnetic field and an alarm is sounded.
