  • Patent number: 9443295
    Abstract: The present invention provides a method and apparatus for reducing artifacts in Computed Tomography (CT) image reconstruction. The method comprises acquiring an original reconstructed image, then conducting total variation processing for the original reconstructed image generating a total variation reconstructed image, conducting an initial metal artifact reduction processing for the original reconstructed image generating an initial metal artifact reduction reconstructed image, generating a weighted image based on the total variation reconstructed image and the initial metal artifact reduction reconstructed image, wherein the weighted image reflects that the original reconstructed image contains white-band artifactsd combining a portion of the original reconstructed image and a portion of the initial metal artifact reduction reconstructed image through the weighted image to generate a final image, wherein the final image does not contain white-band artifact.

  • Patent number: 9444233
    Abstract: Methods, devices, and systems for automated maintenance mode switching are described. An example method of controlling a protection assembly mode of operation is described for use in a system having a protection assembly configured to receive power from an upstream power source and provide power and protection to a downstream protection device moveable between a fully engaged position and a fully disengaged position. The method includes determining, by the protection assembly, when a maintenance action is being performed on the downstream protection device, and switching the protection assembly from a normal protection mode to a maintenance mode of operation in response to determining the maintenance action is being performed on the downstream protection device.

  • Patent number: 9440182
    Abstract: A carbon dioxide absorbent composition is described, including (i) a liquid, nonaqueous silicon-based material, functionalized with one or more groups that either reversibly react with CO2 or have a high-affinity for CO2; and (ii) a hydroxy-containing solvent that is capable of dissolving both the silicon-based material and a reaction product of the silicon-based material and CO2. The absorbent may be utilized in methods to reduce carbon dioxide in an exhaust gas, and finds particular utility in power plants.

  • Patent number: 9441487
    Abstract: The invention relates to a method for welding rotors for power generation having a plurality of rotor discs arranged along a rotor axis. The method includes providing forged and NDT tested rotor discs and machining the discs for weld seam preparation. The weld seam preparation has an inner narrow TIG welding gap and an adjoining outer SAW welding gap. The method further includes stapling the discs on top of each other; and checking the run-out of the stapled discs relative to each other and as a whole and, if necessary, adjusting the staple. In addition the method includes melting the root of the weld without weld filler using TIG welding; increasing the weld height by narrow gap TIG welding with parent metal weld filler to allow tilting of the rotor in horizontal position; tilting the rotor in horizontal position; finalizing the welding by filling the outer SAW welding gap using SAW welding; and checking the welds of the rotor by NDT using ultrasonic testing.

  • Patent number: 9440666
    Abstract: A system includes an energy management system configured to be communicatively coupled with a communication system of a vehicle that travels on a trip along a route. The energy management system is configured to be removably coupled with the communication system such that the energy management system is mechanically disengageable from the communication system. The energy management system is further configured to receive data parameters from the communication system and to generate at least one of a trip plan or a control message for the vehicle based on the data parameters. The trip plan and/or the control message dictates tractive and braking efforts of the vehicle during the trip. The energy management system is configured to communicate the trip plan and/or the control message to the communication system for the communication system to implement for controlling movement of the vehicle during the trip.

  • Patent number: 9444448
    Abstract: High performance gate drives and methods for driving semiconductor switching elements, such as insulated gate bipolar transistors (IGBTs), are provided. The gate drive can control the voltage applied to the gate of the IGBT to one or more intermediate voltages near the threshold voltage of the IGBT to control dv/dt of the collector-emitter voltage during and the di/dt of the collector current turn off. For instance, a voltage level between the turn on voltage and the turn off voltage can be applied for a first time period to control dv/dt of the collector-emitter voltage and di/dt of the collector current during turn off. Another voltage level between the turn on voltage and the turn off voltage can be applied for a second time period during reverse recovery of a freewheeling diode coupled in parallel with the IGBT.
