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 |

20130011144 | METHOD AND APPARATUS FOR NOISE CANCELLATION - Method and apparatus of denoising recurrent signals comprising: providing first and second noisy signals each comprising a deterministic signal and (different realizations of) white noise; selecting one of the noisy signals as an input signal and the other noisy signal as a desired signal; providing an estimate of the deterministic signal in the input signal; determining the error between the estimated deterministic signal and the desired signal; adjusting the estimate of the deterministic signal using the error and producing an adjusted estimate of the deterministic signal. | 01-10-2013 |
20130018633 | METHOD AND APPARATUS FOR CENTRAL FREQUENCY ESTIMATION - A method and apparatus comprising acquiring spectral measurements from an optical fiber sensor. The optical fiber sensor is an SBS-based sensor such as a BOTDA. The acquired measurements are of Brillouin interactions at a point along the optical fiber being excited by the lasers of the SBS-based sensor. The acquired measurements can comprise discreet measurements of the Brillouin gain spectrum (“BGS”) at the point along the fiber. The discreet measurements can be plotted as data points. A BGS can be defined by three parameters: the Brillouin frequency shift (“BFS”), the bandwidth and the peak gain. A Lorentzian curve can be used to model a BGS. A BFS can be determined by estimating the central frequency of the Lorentzian curve which is used to model the BGS. | 01-17-2013 |

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 |
