Patent number: 9002433
Abstract: An MR system and method for tracking a device of an interventional procedure within a scan subject is disclosed. At least two MR projections of the device are acquired, from which 3D coordinates of the device are determined. Subsequent image acquisition is adjusted with respect to the coordinates of the device to guide movement thereof towards target anatomy. The present system and method provide the ability to locate and visualize continuous portions of an interventional device in 3D, and do not require the use of embedded RF localizing coils.

Patent number: 9002615
Abstract: A method and system for online power management of a turbine engine is provided. The method includes operating an engine control system on a first bandwidth, filtering at least one data input from the engine control system to a second bandwidth, and receiving, by a power management system operating on the second bandwidth, the at least one filtered data input. The method also includes predicting an engine operating condition using the at least one filtered data input using a closed-loop engine model, determining an optimal engine power management based on the prediction, solving a constrained optimization for a desired optimization objective, and outputting the optimal engine power management to the engine control system.

Patent number: 9000721
Abstract: An electric vehicle charging station is described. The charging station includes an input connector configured for coupling with an alternating current (AC) power source and an output connector configured for coupling with an electric vehicle. The charging station also includes a variable-output transformer comprising a primary side and a secondary side. The primary side is coupled to the input connector and the secondary side is coupled to the output connector and configured to be in selective electromagnetic communication with an energy storage device associated with the electric vehicle. The charging station also includes a controller coupled to the transformer and configured to determine a level of voltage to provide to the electric vehicle.

Patent number: 9000391
Abstract: A detector includes an outer shell having a shell profile in which a welded portion of the shell profile extends as an annular flange in an outward direction relative to a center axis of the outer shell. The detector further includes an end cap positioned adjacent the welded portion of the outer shell. The end cap and the welded portion of the outer shell are welded together to form a seal. A method of making a detector is also provided.

Patent number: 8999457
Abstract: Methods for making an environmental barrier coating using a sintering aid involving: applying a bond coat layer to the ceramic component; combining at least water and a primary transition material selected from a rare earth disilicate or a doped rare earth disilicate to produce a transition layer slurry; applying at least the transition layer slurry, and optionally an outer layer slurry and/or compliant layer slurry to the component; and sintering the component to produce the environmental barrier coating. The sintering step causes a reaction between a slurry sintering aid and constituents of at least one of the transition, outer and compliant layers to form a secondary material and reduce porosity in the coating.

Patent number: 9003514
Abstract: A system and method to troubleshoot a defect in at least one machine is provided. The system includes a portable device having a tracking system to detect when within a threshold proximity of a machine, and a controller to perform the steps of: authenticating the user to operate the portable device and communicating a first signal including the unique identifier of the portable device in response to detecting when within threshold proximity of the at least one machine. The system can further include an agent located at the machine to receive the first signal from the portable device, and in response to automatically verify authorization of the portable device to access the machine; and automatically trigger transmission of an operational data of the least one machine to the portable device over a secure channel.

Patent number: 8997498
Abstract: A control system is provided. The control system includes at least one sensor that is positioned within a turbine engine and is configured to detect at least one first operating parameter therein. A controller is coupled to the sensor. The controller is configured to receive at least one second operating parameter of the turbine engine. Moreover, the controller is configured to control a flow of a fluid to a rotor assembly within the turbine engine such that at least one of the first operating parameter and the second operating parameter is less than at least one threshold value.
