  • Patent number: 9596469
    Abstract: The entropy coding of a current part of a predetermined entropy slice is based on, not only, the respective probability estimations of the predetermined entropy slice as adapted using the previously coded part of the predetermined entropy slice, but also probability estimations as used in the entropy coding of a spatially neighboring, in entropy slice order preceding entropy slice at a neighboring part thereof. Thereby, the probability estimations used in entropy coding are adapted to the actual symbol statistics more closely, thereby lowering the coding efficiency decrease normally caused by lower-delay concepts.

  • Patent number: 9587520
    Abstract: A novel Rankine cycle system configured to convert waste heat into mechanical and/or electrical energy is provided. In one aspect, the system provided by the present invention comprises a novel configuration of the components of a conventional Rankine cycle system; conduits, ducts, heaters, expanders, heat exchangers, condensers and pumps to provide more efficient energy recovery from a waste heat source. In one aspect, the Rankine cycle system is configured such that an initial waste heat-containing stream is employed to vaporize a first working fluid stream, and a resultant heat depleted waste heat-containing stream and a first portion of an expanded second vaporized working fluid stream are employed to augment heat provided by an expanded first vaporized working fluid stream in the production of a second vaporized working fluid stream. The Rankine cycle system is adapted for the use of supercritical carbon dioxide as the working fluid.

  • Patent number: 9587511
    Abstract: A system and method for measuring and adjusting rotor to stator clearances is disclosed, as well as a turbomachine embodying the system and method. In an embodiment, a turbomachine is assembled, including a stator having an upper and a lower stator shell, and a rotor disposed within the stator. A cold clearance between the rotor and the stator is determined at each of a plurality of clearance measurement points using an in situ clearance sensor system. Each of the clearance measurement points is axially spaced from each other clearance measurement point. The cold clearance between the rotor and the stator is adjusted based on the determined cold clearances, by displacing one of the upper stator shell or the lower stator shell relative to a foundation, thereby changing a shape of the upper stator shell or the lower stator shell to accommodate a position of the rotor within the stator.

  • Patent number: 9586020
    Abstract: The present application includes an independent and redundant measurement of anesthetic concentration, based on acoustic time-of-flight measurements, added to an anesthetic vaporizer. The redundant anesthetic concentration measurement is used to make the vaporizer inherently safe by design and monitor true vaporizer empty. Further, using an acoustic wave splitting technique and the time-of-flight measurements, the flows at the vaporizer inlet and outlet are computed. The flow measurements are used to monitor carrier gas loss, anesthetic consumption, and anesthetic delivery time remaining and provide such information to the vaporizer operator.
