  • Layered coded streaming control for unicast/MBMS interaction
    Patent number: 8910223
    Abstract: A higher network sends a base stream of a data stream to a first network node, and sends an enhancement stream of the data stream to a second network node. The first network node transmits the base stream over a multicast channel and the second network node transmits the enhanced stream in synchronism with the transmitted base stream over a unicast channel. Various options are detailed for how this synchronism is achieved, and the second network node need only transmit the higher bit-rate enhancement stream on user request or if network conditions permit. A user equipment receives the base and enhancement streams, combines them, and displays the combined stream to a user at a graphical display interface. Various apparatus, methods, and computer programs are detailed for various nodes and the user equipment.

  • Method for the manufacture of the blade tips of rotor wheels made in BLISK design
    Patent number: 8850703
    Abstract: With a method for finish-machining the blade tips of rotor wheels made in BLISK design, the rotor wheel or multi-stage compressor rotor (1), is machined—blade by blade and stage by stage—at the blade tips (2) by a conical cutter (5) whose cutting edge (6) is oriented tangentially to the outside surface of the rotor wheel/compressor rotor and routed on the blade tip essentially along the centerline thereof, with the cutting force being introduced perpendicular to the tool axis and in the stiffest direction of the blade (3), i.e. the centerline (11) of the blade cross-section and the perpendicular axis extending from the centerline. The cutting action and the force introduction of the conical cutter at the blade tip allow production of blade tips with a geometrically precisely defined edge without setting the respective blades into vibration.

  • INHIBITORS OF HCV NS5A PROTEIN
    Publication number: 20130310427
    Abstract: Antiviral compounds may be used to inhibit or reduce the activity of Hepatitis C virus (HCV), particularly HCV's NS5A protein. In these contexts, inhibition and reduction of activity of the NS5A protein refers to a lower level of the measured activity relative to a control experiment in which the cells or the subjects are not treated with the test compound. The inhibition or reduction in the measured activity is at least a 10% reduction or inhibition. The compounds and their isomeric forms and pharmaceutically acceptable salts thereof are useful in treating and preventing HCV infection alone or when used in combination with other compounds targeting viral or cellular elements or functions involved in the HCV lifecycle.
