Patent number: 9010082
Abstract: According to one aspect of the invention, a gas turbine engine includes a combustor, a fuel nozzle placed in an end of the combustor, and a passage configured to receive an air flow from a compressor discharge casing, wherein the passage directs the air flow into a chamber downstream of the nozzle, wherein a chamber pressure is lower than a compressor discharge casing pressure. The gas turbine engine also includes a flow control device configured to control the air flow from the compressor discharge casing into the passage.

Patent number: 9014333
Abstract: An image reconstruction method for differential phase contrast imaging includes receiving data corresponding to a signal produced by an X-ray detector and corresponding to X-rays that passed through a subject and a grating system to reach the X-ray detector. The method also includes performing a fringe analysis on the received data. The fringe analysis includes a non-integer fringe fraction correction utilizing one or more adapted basis functions in the Fourier domain to determine one or more Fourier coefficients. A differential phase image of the subject is generated by utilizing the one or more Fourier coefficients.

Patent number: 9012859
Abstract: A tiled imager panel is disclosed. In certain embodiments, the tiled imager panel is formed from separate imager chips that are mechanically tiled together so as to minimize the gap between the tiled imager chips. In addition, in certain embodiments, a scintillator material associated with the tiled imager panel is in a hermetically sealed environment so as to be protected from moisture.

Patent number: 9013904
Abstract: A power transmission system is provided. The power transmission system includes a power source for providing power. The system also includes a power conversion system comprising power converters coupled to receive the power and convert the power to DC power, wherein the power conversion system comprises a plurality of legs each configured for pulse width modulation. The system further includes a controller comprising an analysis module programmed for determining a number of legs for switching for minimizing a cost function based on operating conditions of the power conversion system. The controller also includes a switch control module programmed for using the number of legs determined by the analysis module for generating switching commands for the power conversion system. The system also includes a DC transmission bus coupled to receive the DC power and transmit the DC power.

Patent number: 9014782
Abstract: Versatility and the quality of images are to be improved. As preparation pulses, a first RF pulse to flip along the yz plane spins oriented in a magnetostatic field direction in a subject; a velocity encoding gradient pulse which, in spins flipped by that first RF pulse, mutually shifts the phase of spins in a static state and the phase of spins in a moving state; and a second RF pulse to flip along the yz plane spins whose phase has been shifted by the velocity encoding gradient pulse are successively transmitted. After that, a killer pulse is transmitted to extinguish the transverse magnetizations of the spins flipped by the second RF pulse.
