  • Publication number: 20140013740
    Abstract: An exemplary turbocharger system for an internal combustion engine is provided. The turbocharger system includes a first turbine and a second turbine. The first turbine is in fluid communication with the internal combustion engine. The first turbine receives a first portion exhaust gas discharged from the internal combustion engine and provides a first turbine exhaust gas. The second turbine is in fluid communication with the first turbine via an inter-stage channel. The inter-stage channel transports the first turbine exhaust gas from the first turbine to the second turbine. The inter-stage channel is in thermal connection with an exhaust gas recirculation channel defined between an inlet and an outlet of the internal combustion engine. The first turbine exhaust gas flowing through the inter-stage channel is capable of being heated by a second portion exhaust gas discharged from the internal combustion engine and flowing through the exhaust gas recirculation channel.

    Abstract: A method for obtaining operating parameters of a power plant includes data mining a historical operating condition database for the power plant with a partitional clustering algorithm to generate a statistical model, and calculating dynamic operating condition target values from the statistical model taking into account current operating condition data of the power plant. The method further includes performing a real-time energy-loss analysis based on the dynamic operating condition target values and automatically identifying at least one operating parameter of the power plant from the energy-loss analysis. The partitional clustering algorithm can be a k-means clustering algorithm.

  • Patent number: 7854294
    Abstract: An earmuff assembly with a double-shell structure is disclosed for use with a sound-attenuating circumaural headset. The earmuff assembly comprises a cup-shaped outer shell mounted on a resilient outer sealing ring and a cup-shaped inner shell mounted on a resilient inner sealing ring. By means of the two sealing rings the outer and the inner shells are brought into abutment with the head surface around an ear of a wearer. Both shells are structurally rigid. The sound attenuation performance is maximized by isolating the inner shell from the outer shell.
