  • Patent number: 9822717
    Abstract: A system and method control a powered system having an engine configured to operate using a plurality of fuel types. A first set of control signals including a first set of valve signals are communicated to each fuel tank based at least in part on a first stored engine operating profile to control amounts of fuel provided from each fuel tank to the engine. A different, second set of control signals including a second set of valve signals are communicated to the fuel tanks based at least in part on a second stored engine operating profile to control or change the amounts of fuel from each fuel tank to the engine. The system and method can switch between operating conditions associated with different external domains to alter the engine operating profile used to control the fuel or fuels supplied to the engine.

  • Patent number: 9822670
    Abstract: A power generation system may include: a first gas turbine system including a first turbine component, a first integral compressor and a first combustor to which air from the first integral compressor and fuel are supplied. The first integral compressor has a flow capacity greater than an intake capacity of the first combustor and/or the first turbine component, creating an excess air flow. A second gas turbine system may include similar components to the first except but without excess capacity in its compressor. A turbo-expander may be operatively coupled to the second gas turbine system. Control valves may control flow of the excess air flow from the first gas turbine system to at least one of the second gas turbine system and the turbo-expander, and flow of a discharge of the turbo-expander to an inlet of at least one of the first integral compressor and the second compressor.

  • Patent number: 9825518
    Abstract: An exemplary power conversion system includes a power conversion device and a control system. The power conversion device converts electrical power from one form to another. The power conversion device includes at least one switching element capable of being turned off to block an electrical current flowing through the at least one switching element. The control system is electrically coupled to the power conversion device for monitoring an electrical current flowing through the at least one switching element and for monitoring at least one parameter in association with the operation of the power conversion system. The control system further generates an over-current threshold value that is variable with respect to at least one monitored parameter.

  • Patent number: 9824468
    Abstract: A computationally efficient dictionary learning-based term is employed in an iterative reconstruction framework to keep more spatial information than two-dimensional dictionary learning and require less computational cost than three-dimensional dictionary learning. In one such implementation, a non-local regularization algorithm is employed in an MBIR context (such as in a low dose CT image reconstruction context) based on dictionary learning in which dictionaries from different directions (e.g., x,y-plane, y,z-plane, x,z-plane) are employed and the sparse coefficients calculated accordingly. In this manner, spatial information from all three directions is retained and computational cost is constrained.

  • Patent number: 9824148
    Abstract: A method for searching and displaying scattered logs, comprising: finding out one or more corresponding log data based on a search key word; determining a desired timestamp from the log data, and regarding the log data containing the timestamp as target data; searching a semantic file for related semantic data based on the search key word, and finding out related log data based on the related semantic data; time filtering the related log data to obtain filtered log data; establishing a coordinate system by mapping the target data and the filtered log data onto mapping points of the coordinate system; semantically linking the filtered log data, and dying the filtered log data and the target data; and counting the number of lines related to the target data and the filtered log data, and generating links thereto. The present invention further discloses a device for searching and displaying scattered logs.

  • Patent number: 9822901
    Abstract: An actuating apparatus for operating a valve assembly includes an actuator body that selectively couples to the valve assembly and an actuator stem that has an end that extends into the actuator body. The valve assembly has having a valve body, a valve member in the valve body, a valve stem attached to the valve member, and a profile on an end of the valve stem distal from the valve member. The actuating apparatus also includes an adapter assembly in the actuator body having a threaded end that engages the actuator stem, and a profiled end distal from the threaded end that engages the profile on the valve stem and couples to the valve stem, so that selectively applying axial forces to the adapter assembly moves the valve stem and the valve member.
