A passenger screening system including a first gradiometer, and a second gradiometer disposed adjacent the first gradiometer. The first and second gradiometers are each configured to operate at a first frequency and a second frequency to facilitate detecting the presence of an explosive material. A method of operating the passenger screening system is also described herein.

Passenger screening system and method

An object detection portal wherein a video image is obtained of a volume or area being scanned, and location of a threat object is determined and displayed in real time as an indicator overlay on the video image. An individual subject being scanned may be continuously monitored by an operator during an object divesting process, and an operator may view the threat object moving from or remaining with the subject. Object location information is supplied to a video driver to superimpose the overlay on a real time image of a subject. The scanning portal may interact with an exit barrier. The exit barrier may be activated automatically in response to sensing of a threat.

Object detection portal with video display overlay

A method for determining a location and characterization of an object using a magnetic gradient tensor measurement of the object is provided. The method includes determining an object magnetic field candidate predicted from one of an object measured magnetic field gradient and an assumed object magnetic moment magnitude, and determining an object vector location and an object vector magnetic moment by combining the object magnetic field candidate with an object measured magnetic field.
