  • Patent number: 9664762
    Abstract: A method for reduced field of view magnetic resonance (MR) imaging includes applying a pulse sequence using a plurality of gradient coils and at least one RF coil of a magnetic resonance imaging system. The pulse sequence includes a two dimensional (2D) echo-planar RF excitation pulse with a plurality of side lobes along a slice select axis and a multiband RF refocusing pulse. MR data is acquired in response to the application of the pulse sequence and at least one MR image is reconstructed based on the MR data. The at least one MR image may then be displayed.

  • Patent number: 9427205
    Abstract: An imaging system includes a computed tomography (CT) acquisition unit and at least one processor. The CT acquisition unit includes an X-ray source and a CT detector configured to collect CT imaging data of an object to be imaged. The at least one processor is operably coupled to the CT acquisition unit, and is configured to reconstruct an image using the CT imaging information; extract spatial frequency information from at least a portion of the image, wherein the spatial frequency is defined along a longitudinal direction; and remove a periodically recurring artifact from the at least a portion of the image based on a spatial frequency corresponding to a longitudinal collection periodicity to provide a corrected image.

  • Patent number: 8975768
    Abstract: Wind turbine systems and methods for operating wind turbine systems are provided. In one embodiment, a method includes gating on a dynamic brake switch of a dynamic brake in a wind turbine power converter when an experienced direct current (DC) bus voltage is equal to or greater than a threshold DC bus voltage. The method further includes disabling a threshold temperature rating for the dynamic brake switch when the dynamic brake switch is gated on, and gating off the dynamic brake switch when the experienced DC bus voltage is less than the threshold DC bus voltage.

  • Patent number: 8725384
    Abstract: A turbine to detect a flame holding event includes a combustion section to receive a fluid from a compressor, to heat the fluid by combusting a fuel to generate heat, and to output the heated fluid to a turbine section. The combustion section includes a combustor having a combustion chamber in which the fuel is combusted, and the combustion section having a sensor to sense a static pressure within the combustion chamber. A combustion control device detects a flame holding event in the combustion chamber based only on the sensed static pressure.

  • Patent number: 5551815
    Abstract: A stanchion or hitch for supporting a semi-trailer on a rail car includes a vertical support member having a base end and a top end with a fifth wheel attached to the top end. A base member is attached to the base end of the vertical support member. The base member includes a plurality of releasable connectors for attaching the base member to the bed of the rail car. The fifth wheel is pivotably attached to the vertical support member and includes a king pin protruding from a lower surface for enabling the fifth wheel to be coupled to a fifth wheel on a yard tractor. A diagonal brace extends between the base member and the vertical support member to prevent collapse of the vertical support member. The rail car bed is modified to accept the connectors on the base member in multiple positions so that the stanchion is selectably positionable at various locations on the rail car.

  • Patent number: 4785634
    Abstract: The use of hot gas generators which produce corrosive or abrasive products of combustion have precluded the use of gas turbines in a direct flow path of the combustion products. It is preferable to utilize non-contact gas to gas heat exchangers in order to transfer heat from a hot gas stream to a working fluid. A first heat exchanger connected to a gas furnace is used to raise the temperature of an air turbine inlet gas. A second heat exchanger is used to raise the temperature (prewarm) of compressor discharge air to the air turbine air inlet, the second heat exchanger connected to the air turbine exhaust. A third heat exchanger preheats the air input into a furnace.
