  • Patent number: 9943279
    Abstract: Various methods and systems for weighting material density images based on the material imaged are disclosed. In one embodiment, a method for dual energy imaging of a material comprises generating an odd material density image, generating an even material density image, applying a first weight to the odd material density image and a second weight to the even material density image, and generating a material density image based on a combination of the weighted odd material density image and the weighted even material density image. In this way, the image quality may be improved without increasing a radiation dosage.

  • Patent number: 9945264
    Abstract: A control method for optimizing or enhancing an operation of a power plant that includes thermal generating units for generating electricity. The power plant may include multiple possible operating modes differentiated by characteristics of operating parameters. The method may include tuning a power plant model so to configure a tuned power plant model. The method may further include simulating proposed operating modes of the power plant with the tuned power plant model. The simulating may include a simulation procedure that includes: defining a second operating period; selecting the proposed operating modes from the possible operating modes; with the tuned power plant model, performing a simulation run for each of the proposed operating modes whereby the operation of the power plant during the second operating period is simulated; and obtaining simulation results from each of the simulation runs.

  • Patent number: 9945266
    Abstract: A combined cycle power plant includes a gas turbine having a primary flow passage, a heat recovery steam generator having a heat exchanger disposed downstream from the primary flow passage, an exhaust stack in fluid communication with the primary flow passage and disposed downstream from the heat recovery steam generator and a reversible turning gear coupled to a rotor shaft of the gas turbine. The reversible turning gear counter rotates the rotor shaft during turning gear counter rotation operation of the gas turbine and reverses flow of combustion exhaust gas from the exhaust stack through the heat exchanger and back into the primary flow passage of the gas turbine, thereby conserving thermal energy stored in the heat recovery steam generator. A method for conserving thermal energy of a combined cycle power plant during counter rotation turning gear operation of the gas turbine is also disclosed.

  • Patent number: 9948290
    Abstract: An apparatus includes a switch module, a sense circuit coupled to the switch module and configured to indicate an operating conduction mode of the switch module, and a drive circuit operatively coupled to the switch module to enable and disable forward conducting mode of the switch module. Once the switch module is in forward conducting mode, the drive circuit is configured to maintain enablement of the forward conducting mode even if the sense circuit indicates reverse conduction mode.

  • Patent number: 9946902
    Abstract: This invention provides a system and apparatus that is able to authenticate and prevent illegal manufacturing and unauthorized operation of disposable bioprocess components. This invention utilizes a ferro-electric random access memory chip (FRAM) chip to store error-correctable information on a RFID tag attached to the disposable bioprocess components, where the error-correctable information is written in sequence into the memory chip, so that the redundant information can remain in the chip when the RFID tag and disposable bioprocess component is gamma-sterilized. Also, this invention includes a method for authenticating the disposable bioprocess component that reduces liability in that a counterfeit poor quality disposable component is not used on the hardware so the user will not file an unjustified complaint.
