| 20110206240 | DETECTING CONCEALED THREATS - Potential threat items may be concealed inside objects, such as portable electronic devices, that are subject to imaging for example, at a security checkpoint. Data from an imaged object can be compared to pre-determined object data to determine a class for the imaged object. Further, an object can be identified inside a container (e.g., a laptop inside luggage). One-dimensional Eigen projections can be used to partition the imaged object into partitions, and feature vectors from the partitions and the object image data can be used to generate layout feature vectors. One or more layout feature vectors can be compared to training data for threat versus non-threat-containing items from the imaged object's class to determine if the imaged object contains a potential threat item. | 08-25-2011 |

| 20110239890 | Thermite-Metal Foam - The present invention discloses materials, systems and methods for creating metal foams to envelop targets, which involve the formulation of powdered thermite/metal matrices. Essentially, each matrix will include thermite and a foaming agent. Additionally, a thickening agent can be blended into the powdered thermite/metal matrix to create desirable foaming properties when the thermite is ignited. A heat sink agent can also be dispersed throughout the powdered thermite/metal matrix to limit temperature rise in the matrix during a thermite reaction. Further, a binder can be combined with the powdered thermite/metal matrix to hold the formulation together. In use, the formulation is delivered to the vicinity of the target where it is ignited. The resultant metal foam is intended to envelop and neutralize the target. | 10-06-2011 |

| 20110140009 | Efficient High-Harmonic-Generation-Based EUV Source Driven by Short Wavelength Light - Extreme ultraviolet radiation is generated based on high-order harmonic generation. First, a driver pulse is generated from a drive laser. Second, the infrared driver pulse is passed through a second harmonic generator with an output wavelength in the range from 400 to 700 nm. Third, the pulse is then passed through a gas medium, which can be inside a resonant cavity, to generate a high-order harmonic in the form of extreme ultraviolet radiation. | 06-16-2011 |
| 20110273763 | Cavity-Enhanced Parametric Amplification at Full Repetition Rate - Seed light pulses and pump light pulses are generated; the seed light pulses are preferably chirped; and both are directed into an enhancement cavity at a full repetition rate. The enhancement cavity defines a closed optical path that contains a nonlinear medium that provides phase matching at a wavelength different from both the central seed wavelength and the central pump wavelength. The generation of the pump light pulses and the seed light pulses are synchronized to pass the seed light pulses through the nonlinear medium simultaneously with the pump light pulses to parametrically amplify the seed light pulses in the nonlinear medium to produce an amplified signal pulse and idler pulse. Increased conversion with low average pump power can be achieved, as well as gain bandwidth enhancement approaching octave-spanning levels. Additionally, in the case of chirped pump pulses with sufficient bandwidth, optimal output coupling can be designed to achieve the best impedance matching at each temporal coordinate and attain the highest possible conversion and bandwidth. | 11-10-2011 |

| 20100039126 | NANOCHANNEL-BASED SENSOR SYSTEM FOR USE IN DETECTING CHEMICAL OR BIOLOGICAL SPECIES - A sensor system for detecting a chemical or biological species includes a sensing element and a bias and measurement circuit. The sensing element includes nanochannels, each having an outer surface functionalized to chemically interact with the species to create a corresponding surface potential, and each having a sufficiently small cross section to exhibit a shift of a differential conductance characteristic into a negative bias operating region by a shift amount dependent on the surface potential. The bias and measurement circuit applies a bias voltage across two ends of the nanochannels sufficiently negative to achieve a desired dependence of the differential conductance on the surface potential, wherein the dependence has a steeply sloped region of high amplification substantially greater than a reference amplification at a zero-bias condition, thus achieving relatively high signal-to-noise ratio. The bias and measurement circuit converts the measured differential conductance into a signal indicative of presence or activity of the species of interest. | 02-18-2010 |

| 20090143668 | ENHANCEMENT OF MRI IMAGE CONTRAST BY COMBINING PRE- AND POST-CONTRAST RAW AND PHASE SPOILED IMAGE DATA - An MRI process and system image a volume of a sample in a magnetic field established by a biasing field magnet and an array of gradient magnet fields using a pulse sequence to obtain a response that is decoded into an image or images. A set of successive images is collected while the contrast associated with lesions and tumors is enhanced with a contrast agent. A non-spoiled reference image is acquired before the application of the contrast agent. The reference image is non-spoiled in that the pulse sequence for collecting a portion of the volume image is not randomized in phase in a manner that would reset the phase effects of a previous pulse sequence. At least one other one of the successive images collected using phase spoiling pulse sequences. The non-spoiled image data is registered with and subtracted from the successive images to enhance the appearance of selected compositions in the output image, such as the contrast agent and/or water to highlight lesions and cysts, or silicone from an implant, etc., which can be highlighted by color coding. | 06-04-2009 |
| 20090143669 | COLOR MAPPED MAGNETIC RESONANCE IMAGING - A method and system estimate the risk of malignancy of a given region of interest using noninvasive MRI techniques. The determination of risk is based on the morphology and kinetic enhancement of a region of interest. In addition, the method and system use the type of the enhancement curve to determine the level of risk associated with a given region of interest. The region of interest can be a lesion, tumor, or other unknown. The imaging can be done with the aid of a contrast agent. Regions meeting component concentration criteria, time-change dynamic criteria and the like are distinctly colored and displayed on a single image. Different colors can be shown locally to identify predetermined levels of risk, and/or associated with predetermined compositions such as contrast agents, or to show the presence of silicone. | 06-04-2009 |
| 20090143672 | METHOD FOR MAPPING IMAGE REFERENCE POINTS TO FACILITATE BIOPSY USING MAGNETIC RESONANCE IMAGING - In NMR/MRI imaging, a location is noted for a point in the imaged space, and referred to a reference location so that the point in imaged space is known thereafter, without the need to locate the point again in further imaging steps. For breast cancer diagnosis and biopsy, a breast holding fixture immobilizes the breast. A volumetric image is taken encompassing a portion of the breast. In the same or a subsequent image, a fiducial mark is detected to determine the position of a holder for a biopsy tool or other modality. The tissue feature can be a tumor, cyst or tubal lesion, made temporarily visible in the image by perfusion with a contrast agent. After the contrast agent dissipates, the location of the tissue feature can still be determined by reference to the position of the fiducial marker, which is optional adjustable by post-imaging metered displacement. | 06-04-2009 |
| 20100145185 | EXTENDING THE RESOLUTION OF MRI DATA BY COMBINING SUBSETS FROM PLURAL IMAGE ACQUISITIONS - An MRI image from spiral trajectory scanning is arranged as complementary subsets of values in time-sampled k-space. These values are Fourier transformed to produce a spatial domain image. While holding the patient stationary, the contrast information is updated at the central portion of k-space, and the peripheral portion of k-space data can be filled during the whole image acquisition. The contrast information is combined with the peripheral portion of k-space (contributing to image resolution) to construct a full k-space data and to generate a spatial image. The technique is useful for providing short time interval sampling when analyzing the take-up and fade-away of a contrast agent over time. | 06-10-2010 |
