  • Patent number: 9472783
    Abstract: The present techniques provide systems and methods for protecting electronic devices such as organic light emitting devices (OLEDs) from adverse environmental effects using a thin film encapsulation with reduced process time. In some embodiments, the process time of forming a graded barrier over the OLED structure may take less than 5 minutes, and may result in substantially similar barrier properties as those of metal and epoxy sealants and/or typical thin film encapsulations. The process time of forming the barrier may be reduced by increasing deposition rates for organic and/or inorganic materials, reducing the thicknesses of organic and/or inorganic layers, and/or varying the number of zones in the barrier.

  • Patent number: 9473169
    Abstract: Decomposing a value range of the respective syntax elements into a sequence of n partitions with coding the components of z laying within the respective partitions separately with at least one by VLC coding and with at least one by PIPE or entropy coding is used to greatly increase the compression efficiency at a moderate coding overhead since the coding scheme used may be better adapted to the syntax element statistics. Accordingly, syntax elements are decomposed into a respective number n of source symbols si with i=1 . . . n, the respective number n of source symbols depending on as to which of a sequence of n partitions into which a value range of the respective syntax elements is sub-divided, a value z of the respective syntax elements falls into, so that a sum of values of the respective number of source symbols si yields z, and, if n>1, for all i=1 . . . n?1, the value of si corresponds to a range of the ith partition.

  • Patent number: 9464530
    Abstract: The present application and the resultant patent provide a turbine bucket for a gas turbine engine. The turbine bucket may include an airfoil, a tip shroud positioned radially outward from the airfoil, and a seal rail positioned radially outward from the tip shroud and extending in a generally tangential direction from a first end to a second end of the tip shroud. The seal rail may include a maximum axial thickness at a location positioned between the first end and the second end and offset from the airfoil in the generally tangential direction. The present application and the resultant patent further provide a gas turbine engine and a method for balancing a tip shroud of a turbine bucket of a gas turbine engine.

  • Patent number: 9464538
    Abstract: A shroud block segment for a gas turbine includes a main body having a leading portion, a trailing portion, a first side portion and an opposing second side portion that extend axially between the leading portion and the trailing portion. The main body further includes an arcuate combustion gas side, an opposing back side and a cooling chamber defined in the back side. A cooling plenum and an exhaust passage are defined within the main body where the exhaust passage provides for fluid communication out of the cooling plenum. An insert opening extends within the main body through the back side towards the cooling plenum. A cooling flow insert is disposed within the insert opening. The cooling flow insert comprises a plurality of cooling flow passages that provide for fluid communication between the cooling chamber and the cooling plenum.
