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 |

20080300807 | Electric Winding Displacement Detection Method and Apparatus - A method and system for obtaining the characteristic impedance of an electrical winding by measuring the input and output voltages and the currents within a winding across a low frequency range, and applying transmission line properties to model the winding. The characteristic impedance (Zc) is directly proportional to the capacitance of the winding, and is independent of external circuits. Thus any changes to Zc will reflect movements of the winding that would affect the capacitance. Because Zc has a smooth and robust monotonical relationship with frequency of the applied signal, the resulting curve is exponential in shape. A relative comparison between Zc curves will provide a clear indication of the overall axial or radial winding movements, or winding faults, which can be used to assess the overall health of the winding. | 12-04-2008 |

20110144970 | Apparatus and method for partitioning a display surface into a plurality of virtual display areas - A method and apparatus that partitions a single display's viewable area into at least two virtual viewable areas, and emulates the at least two virtual viewable areas as at least two emulated physical displays with an operating system such that the operating system behaves as if interfacing with at least two actual independent physical displays. The method provides the operating system with generated display identification data (such as “EDID”) for each of the emulated physical displays in response to a query from the operating system. The method and apparatus also receive notification of an interrupt (where the interrupt corresponds to the single physical display), and reports to the operating system with at least two sets of interrupt reporting information, corresponding to the at least two emulated physical displays, as if two interrupts were received. The operating system is thereby “faked” into acting as if two physical displays are in operation. | 06-16-2011 |

The user mode driver may call a DDI for rendering an overlay frame while simultaneously passing the overlay property data to the KMD. The KMD may store the overlay property data in an overlay flip queue, program the overlay hardware per the overlay property data stored in the overlay flip queue, and flip the overlay in response to the vertical synchronization deferred procedure call. | 06-13-2013 |

20090101296 | Near Neutral Chlorine Dioxide Bleaching of Pulp - Final chlorine dioxide bleaching of lignocellulosic materials is most effective at a near-neutral pH but present industrial practice typically targets a final pH of between 3.5 and 4.0 because of the difficulty in achieving and maintaining near-neutral pH cost effectively. The in situ formation of bicarbonate before the addition of chlorine dioxide provides a way of maintaining the required near-neutral pH. Near-neutral final chlorine dioxide bleaching also produces a bleached pulp that is in a state that responds more effectively to fluorescent whitening or optical brightening agents. | 04-23-2009 |
