| 20110151575 | Energetic Material Detector - Energy released from energized particles is sensed. Whether the energized particles include a possible energetic material is determined based on the sensed energy. If a determination is made that the energized materials include a possible energetic material, a spectral signature of the sensed energy is determined. The spectral signature of the sensed energy is compared to one or more known spectral signatures associated with energetic materials. Whether the possible energetic material is an actual energetic material is determined based on the comparison. | 06-23-2011 |

| 20110148686 | MOVING-ENTITY DETECTION - Sensing moving entities includes transmitting a stepped-frequency radar signal including multiple frequencies through a wall from a first side of the wall to a second side of the wall. Portions of the radar signal that are reflected by entities located beyond the second side of the wall are detected. The reflected portions are processed to generate processed data including information associated with frequency shifts between the transmitted signal and the detected signal. The processed data is analyzed to determine if reflected portions are associated with moving entities. | 06-23-2011 |
| 20110068795 | CONTINUOUS WAVE METAL DETECTOR - A training set including a target object set and a clutter object set is accessed. It is determined that the training set includes multiple types of targets or multiple types of clutter. The target feature value of a type of target is compared with the clutter feature value. The type of target is associated with the non-target object based on the comparison. A classifier is trained using the target feature value and the clutter feature value of the associated type of target and the non-clutter object. A feature value associated with an unknown object is applied to multiple classifiers to generate a set of metrics for the unknown object. The metrics are aggregated into an overall metric. Whether the unknown object is included in the target set is determined based on the overall metric. | 03-24-2011 |
| 20110024626 | TRACE SAMPLING - A trace sampling detection system includes a gathering device configured to gather particles through a handle-bar, a gate and an air-stream gatherer. The handle-bar includes collection holes positioned to be adjacent to a user's hand when the user grips the handle-bar, and is configured to dislodge and capture particles from the user's hand when the user grips and moves the handle-bar. The gate includes a series of collection holes, is positioned to be adjacent to the user's clothing when the user traverses the gate, and is configured to dislodge and capture particles from the user's clothing in response to pressure applied from the user. The air-stream gatherer includes an outward vent and an in-drawing vent, and is positioned to enable objects, such as the user's feet, to be placed between the outward and in-drawing vents. The air stream is configured to dislodge and capture particles from objects, such as the user's feet, that block the air-stream between the vents. A collection tube is configured to deposit gathered particles from the gathering device onto a portion of a sample media. A carousel wheel that includes the sample media is configured to rotate the sample wheel such that the portion of the sample media including the gathered particles is presented to an exothermic decomposition detector that detects, through an infrared sensor, the decomposition of the gathered particles. | 02-03-2011 |
| 20100277397 | Detection of surface and buried objects - An antenna includes a resistive element formed in a casing, and a feed line formed in the casing and electrically coupled to the resistive element. The positioning of the resistive element and the feeding is such that the feed line is approximately perpendicular to the resistive element. The positioning of the feed line and the resistive element may result in the antenna being sized to allow integration of the antenna into a sensor head. | 11-04-2010 |

| 20090262006 | MOVING-ENTITY DETECTION - A system and method for detecting entities based on movement can involve transmission circuitry configured to enable transmission of a stepped-frequency radar signal, an antenna, and receiving circuitry configured to generate data including information associated with frequency and phase shifts between the transmitted signal and the reflections of the transmitted signal. The system also can involve a processor configured to analyze the generated data to determine information associated with a moving object located at a side of a wall different than a side of the wall of which the system is located. The analyzing can involve compensating for the effect of motion of the system on the phase shifts between the transmitted signal and the reflections of the transmitted signal. | 10-22-2009 |
| 20090262005 | MOVING-ENTITY DETECTION - A system and method for enabling transmission of a stepped-frequency radar signal can involve a first antenna and a second antenna.

The system can further involve a processor configured to receive the generated data from the receiving circuitry and to analyze the generated data to determine information associated with a moving object located at a side of a wall opposite to the system by differentiating reflections of the transmitted signal detected with the first antenna from reflections of the transmitted signal detected with the second antenna. | 10-22-2009 |
| 20090044641 | TRACE SAMPLER - A position of an object moving through a region of interest is determined, and at least one source of an air stream is selectively activated based on the determined position. The air stream is capable of dislodging a particle from the object moving through the region of interest. The air stream is directed toward the region of interest. An air collector is selectively activated, based on the determined position, to draw air from the region of interest. The drawn air is deposited on a sample collector, and the sample collector is analyzed to determine whether the deposition of the air stream left particles of a material of interest on the sample collector. | 02-19-2009 |
