20090256570 | Method For Joint Sparsity-Enforced K-Space Trajectory and Radiofrequency Pulse Design - A system and method is provided for simultaneously designing a radiofrequency (“RF”) pulse waveform and a magnetic field gradient waveform in a magnetic resonance imaging (“MRI”) system. The method includes determining a desired pattern of RF excitation and determining, from the desired pattern of RF excitation, a plurality of k-space locations indicative of the magnetic field gradient waveform and a plurality of complex weighting factors indicative of RF energy deposited at each k-space location. The method also includes calculating, from the determined k-space locations, the magnetic field gradient waveform and calculating, from the complex weighting factors, the RF pulse waveform that will produce the desired pattern of RF excitation when produced with the calculated magnetic field gradient. | 10-15-2009 |

20100052679 | Coil Array Mode Compression For Parallel Transmission Magnetic Resonance Imaging - A method for target-dependent, sparsity-enforced selection for choosing a substantially optimal connection of radiofrequency (“RF”) transmitters to the elements of the RF coil array is provided. In particular, a method is provided that selects the linear combinations of the “N” spatial mode profiles of a transmission RF coil array, such that the k-space trajectory and pulse duration acceleration capabilities of the array are advantageously utilized. A sparsity-enforcement method that determines a subset of the available spatial modes for a parallel transmission RF coil array is employed to this end. In this manner, the utilization of the encoding power of a highly-parallel N-mode coil array in a system with only “P” available excitation channels is enabled. | 03-04-2010 |
20100134105 | Method For Reducing Maximum Local Specific Absorption Rate In Magnetic Resonance Imaging - A method for reducing maximum local specific absorption rate (“SAR”) in a magnetic resonance imaging (“MRI”) system is disclosed. More specifically, a plurality of candidate radio frequency (“RF”) pulses are designed and the manner in which they are applied to a subject is determined such that the maximum local SAR is substantially reduced relative to applying the candidate RF pulse that produces the lowest maximum local SAR alone. Put another way, this “time-multiplexing” of a set of RF pulses that each produce approximately the same excitation pattern yields a lower maximum local SAR than does transmitting the individual RF pulse having the lowest local SAR over many repetition times (“TRs”). A convex optimization method is utilized to determine the manner in which the RF pulses are multiplexed in time such that a substantially lower maximum local SAR is achieved. | 06-03-2010 |

20100012422 | FLAPPER CONFIGURATION FOR MARINE EXHAUST SYSTEM - Disclosed are apparatus and methodology for reducing noise and wear in a flapper configured exhaust tip for a marine exhaust system. A flapper, normally located within an exhaust tip of a marine exhaust system, is relocated upstream of the point in the exhaust system where cooling water normally contacts the exhaust pipe. An exhaust tip is coupled to the upstream portion of the exhaust system by way of an elastomeric coupling device. The flapper is positioned such that a tip thereof contacts the elastomeric coupling rather than the metallic exhaust pipe. Such contact with an elastomeric coupling device reduces noise previously produced by flapper contact with the hot exhaust pipe occasioned by destruction and/or heat degeneration of elastomeric material generally associated with the flapper device. | 01-21-2010 |

A metallic flapper is located at an end portion of an exhaust tip of the exhaust pipe. An elastomeric flapper assembly is provided covering the exhaust tip and includes a lip portion configured to provide noise reduction by functioning as a stop for a tip portion of the metallic flapper. The metallic flapper is positioned such that a tip thereof contacts the elastomeric flapper assembly rather than the metallic exhaust pipe. Such contact with an elastomeric flapper assembly reduces noise previously produced by flapper contact with the hot exhaust pipe. | 01-20-2011 |

20120075695 | HOLDER FOR CARRYING AND FACILITATING AUTO-LOADING OF MICROSCOPE SPECIMEN SLIDES - Pathology specimen slides are positively located on trays, and picked and placed by an auto-loader. The trays are received in a rack in tiers accessed by an auto-loader that moves the slides between the trays and a digital imaging microscope. The trays can have rows of receptacles for slides with standoff structures spacing the slides above a tray bottom. Lateral and endwise partitions defining the receptacles are inclined oppositely inwardly for guiding a slide into the predetermined position on the tray. The autoloader has a manipulator that grasps the ends of slides presented in a front row, and can reach over the front row to grasp slides in one or more rows beyond the front. The manipulator lifts the slide between the inclined surfaces of the partitions, loads and later retrieves the slide from the microscope and replaces the slide in the holder. | 03-29-2012 |
