  • Patent number: 9729891
    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. Temporal interrelationships are exploited additionally or alternatively.

  • Patent number: 9719685
    Abstract: A system and method for flame stabilization is provided that forestalls incipient lean blow out by improving flame stabilization. A combustor profile is selected that maintains desired levels of power output while minimizing or eliminating overboard air bleed and minimizing emissions. The selected combustor profile maintains average shaft power in a range of from approximately 50% up to full power while eliminating overboard air bleed in maintaining such power settings. Embodiments allow for a combustor to operate with acceptable emissions at lower flame temperature. Because the combustor can operate at lower bulk flame temperatures during part power operation, the usage of inefficient overboard bleed can be reduced or even eliminated.

  • Patent number: 9719816
    Abstract: A fitting for positioning a probe in a hot gas path within a casing of a gas turbine engine is disclosed herein. The fitting includes a main body attachable to the casing opposite the hot gas path. The main body includes an internal bore and one or more cooling holes in communication with the internal bore. A compliant seal is positionable within the internal bore. In addition, a follower is positionable within the internal bore adjacent to the compliant seal. Moreover, the fitting includes a fastener configured to mate with the main body. In this manner, the follower deforms the compliant seal about the probe within the main body to secure and seal the probe within the main body.

  • Patent number: 9720043
    Abstract: A method of testing a fuse in apparatus for monitoring electrical insulation surrounding first and second electrical conductors in a cable, the fuse being connected to the conductors, comprises: applying an electrical signal, with respect to a reference, to the fuse from a source; obtaining a value for the resistance of the insulation with respect to the reference; determining if the resistance value is greater than a fuse test resistance threshold and, if it is, causing the application of the signal to cease; and monitoring the decay of the signal to determine if the time for it to decay below a set value exceeds a set time limit, indicative of the fuse being satisfactory, or is less than the limit indicative of the fuse being blown.

  • Patent number: 9720063
    Abstract: Systems and methods for generating a magnetic resonance (MR) image of a tissue are provided. A method includes acquiring MR raw data. The MR raw data corresponds to MR signals obtained at undersampled q-space locations for a plurality of q-space locations that is less than an entirety of the q-space locations and the MR signals at the q-space locations represent the three dimensional displacement distribution of the spins in the imaging voxel. The method also includes performing a joint image reconstruction technique on the MR raw data to exploit structural correlations in the MR signals to obtain a series of accelerated MR images and performing, for each image pixel in each accelerated MR image of the series of accelerated MR images, a compressed sensing reconstruction technique to exploit q-space signal sparsity to identify a plurality of diffusion maps.
