| 20100148777 | MAGNET ARRAY - A magnet array is disclosed which is suitable for inter alia producing a remote field for use in unilateral magnetic resonance. In the “Magnet Array”, two separated magnets, which are magnetized along a substantially same collinear magnetization direction, produce a field with a local maximum centered above and between them. The field produced by the two separated magnets is substantially parallel to the collinear magnetization direction of the two separated magnets. A third magnet is centered between the two separated magnets. The third magnet has a magnetization direction which is substantially parallel to the collinear magnetization direction of the two separated magnets. The third magnet produces a field which is substantially parallel to the collinear magnetization direction of the two separated magnets, and adds to the increasing field below the local maximum point produced by the two separated magnets. The field of the third magnet, which decays with distance, adds to the increasing field below the local maximum point. The position of the third magnet is selected in order to generate a total field which has at least one of its first and second spatial derivatives with respect to the distance above the magnet array substantially equal to zero. | 06-17-2010 |

| 20090186658 | JOINT COMMUNICATION AND ELECTROMAGNETIC OPTIMIZATION OF A MULTIPLE-INPUT MULTIPLE-OUTPUT ULTRA WIDEBAND BASE STATION ANTENNA - Recent work has shown that in nearly line-of-sight (LOS) Multiple-Input Multi-Output (MIMO) wireless communication systems, spacing antennas according to the symbol wavelength rather than the carrier wavelength improves multiuser performance. MIMO systems have a heavy reliance on a multipath rich environment, which may not always be present in close range ultra wideband conditions. By adding reflector elements to the antenna structure, this multipath rich environment can be induced. The performance of the users with respect to the arrangement of antennas and reflector elements is a non-linear function that a genetic algorithm (GA) seems applicable for exploiting both symbol-wavelength spacing and multipath inducing reflector elements. A GA optimization is used to determine the optimum characteristics for antennas and reflector elements. MIMO system models with four users, and three, four, and five antennas are considered using a two-dimensional LOS channel with additive white noise. Subsequently, a GA optimization design and approach for solving this problem in three-dimensional space is presented. The addition of reflector elements to purposely increase multipath requires additional design considerations incorporating distributed processing, ray-tracing, and the determination of the channel impulse response. | 07-23-2009 |

| 20120071334 | Methods And Marker Combinations For Screening For Predisposition To Lung Cancer - The present invention relates to rapid, sensitive methods for determining whether a subject has or is at risk of developing lung cancer based on certain combinations of biomarkers, or biomarkers and biometric parameters. The methods consist of: a) quantifying in a test sample obtained from a subject, the amount of two or more biomarkers in a panel, the panel comprising at least one antibody and at least one antigen: b) comparing the amount of each biomarker quantified in the panel to a predetermined cutoff for said biomarker and assigning a score for each biomarker based on said comparison: c) combining the assigned score for each biomarker quantified in step b to obtain a total score for said subject: d) comparing the total score in step c with a predetermined total score and e) determining whether said subject has a risk of lung cancer based on the comparison in step d. | 03-22-2012 |
