Alexander Robert Perry - San Diego CA, US

Assignee:

GE Homeland Protection, Inc. - Newark CA

International Classification:

G01C 9/00

US Classification:

702150, 702 6, 702 94, 702 95, 324179, 324333, 324345, 324377

Abstract:

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.

International Classification:

H04N 7/18

US Classification:

348143, 348156

Abstract:

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.

International Classification:

G08B 13/24

US Classification:

340551, 324244

Abstract:

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.

US Classification:

385/060000, 385/078000

Abstract:

A coupler for coupling first and second fiber optic cables terminating in first and second connectors having first and second ferrules, respectively. The coupler includes a holder element and a mating element. The holder element defines a channel for receiving the first ferrule and a socket aligned with the channel for receiving an optical component The holder element further defines a first cable connector adapted for connection to the first connector and a first element connector opposite said first cable connector. The mating element defines a channel for receiving the second ferrule, a second cable connector adapted for connection to the second connector and a second element connector opposite the second cable connector. Accordingly, the holder element and mating element are connectable to house an optical component aligned with the channels and positionable substantially contiguous with the first and second ferrules when attached thereto.
