| 20080315874 | PASSENGER INSPECTION SYSTEM AND METHODS FOR USING THE SAME - A passenger inspection system includes a metal detection sensor integrated with a quadrupole resonance sensor and configured to detect weapons and/or explosives that may be present proximate the feet and/or lower legs of a person. Additionally, a weapons detection sensor may include one or more pairs of transmit coils and receive coils that are vertically mounted to the interior sidewalls of the passenger inspection system and configured to detect symmetrical and nonsymmetrical threats present on a portion of a person's legs. Methods for operating embodiments of the passenger inspection system are also disclosed. | 12-25-2008 |
| 20090153346 | PASSENGER SCREENING SYSTEM AND METHOD - A method and scanner configured to determine whether a person's feet are positioned at a predetermined location of a predetermined scanning area and configured to scan the feet to detect a presence of a metal, an explosive, or other type of target substance. | 06-18-2009 |
| 20100123571 | INSPECTION SYSTEM AND METHOD - A method includes determining a position of a person within an inspection system, and performing a sensor system scan using a sensor system within the inspection system. The sensor system scan includes detecting an unusual physical characteristic of at least one of the person and an item on the person. The results of the sensor system scan are output. | 05-20-2010 |
| 20100142672 | X-RAY LAMINOGRAPHY DEVICE, OBJECT IMAGING SYSTEM, AND METHOD FOR OPERATING A SECURITY SYSTEM - An x-ray laminography device includes at least one x-ray detector and at least one x-ray source coupled in coordinated traversal with the at least one x-ray detector. The at least one x-ray source is configured to generate and transmit x-rays. The at least one x-ray detector and the at least one x-ray source traverse an at least partially radial travel path in unison about an object such that the object is illuminated with x-rays from a plurality of oblique radial angles defined between the at least one x-ray source and the object. | 06-10-2010 |
| 20100212401 | SCREENING SYSTEM AND METHOD - A method of operating a screening system includes applying an electromagnetic field to a specimen in a region at least partially enclosed by electromagnetic shielding and measuring an output from a sensor, wherein the output is induced by an interaction of the electromagnetic field and the specimen. The method also includes dislodging trace particles from the specimen within the region, collecting the trace particles, and identifying the trace particles. The method further includes evaluating an association of the specimen with a substance based on the measured sensor output and the identified trace particles. | 08-26-2010 |
| 20100213365 | SCREENING SYSTEM AND METHOD FOR OPERATING THE SAME - A method of operating a screening system includes applying an electromagnetic field to a subject in a region at least partially enclosed by electromagnetic shielding, and measuring an output from a sensor. The output is representative of an interaction of the electromagnetic field and the subject. A trace vapor is collected from the subject within the region, and the trace vapor is identified. Based on the measured sensor output and the identified trace vapor, whether a target material is associated with the subject is determined. | 08-26-2010 |
| 20110187535 | METHODS, SYSTEMS, AND APPARATUS FOR DETECTING MEDICAL DEVICES - A passenger screening device includes a transmission coil that is configured to apply radio frequency (RF) energy into a region of interest of a passenger at a frequency that is associated with a normal human body temperature, and a reception coil that is configured to detect an energy perturbation in response to the RF energy representative of a medical device on or within the passenger. | 08-04-2011 |
| 20110193558 | PASSENGER SCANNING SYSTEMS FOR DETECTING CONTRABAND - A passenger scanning system includes a passenger screening area configured for a person to enter and a shield surrounding at least a portion of the passenger screening area. The shield is configured to reduce a radio frequency interference within the passenger screening area. The passenger scanning system also includes one or more sensors positioned in the passenger screening area at a height configured to be proximate one or more of an abdominal region, a groin region, and a pelvic region of the entered person. The sensors are configured to generate a signal in response to a target substance located in the one or more of the abdominal region, the groin region, and the pelvic region. | 08-11-2011 |
