  • Patent number: 11846201
    Abstract: A turbine rotor includes a rotor body and a balancing weight slot defined in an exterior circumference of the body. The balancing weight slot has a first axial width and a first radially outward facing surface at a first radial distance from a rotor axis. The rotor also includes a balancing weight entry port defined in a portion of the exterior circumference of the rotor body and aligned with the balancing weight slot. The balancing weight entry port has a second axial width greater than the first axial width and a second radially outward facing surface at a second radial distance from the axis of the rotor body that is smaller than the first radial distance. A method may include machining the entry port into the rotor with a tool. The method may be applied to a new rotor, or to remove cracks initiating from a previous entry port.

  • Patent number: 10920592
    Abstract: A method of assembling a rotor is provided, in which each rotor disk comprising a connecting element. The method includes: (a) applying heat to a localized region of a first rotor disk of a plurality of rotor disks to selectively deflect a first connecting element of the first rotor disk, wherein the first rotor disk is stationary during heating; (b) installing the first rotor disk onto a rotor stack containing at least one rotor disk; and (c) repeating steps (a) and (b) for each rotor disk of the plurality of rotor disks; and (d) allowing the rotor disks, when stacked, to cool. When cooled, the respective connecting element of each rotor disk that has been selectively deflected contracts into an interference fit with an adjacent rotor disk. A system for selectively heating a localized region of a rotor disk is also provided.

  • Patent number: 10477310
    Abstract: A method includes performing, at a processor, signal processing operations on signals captured by each microphone in a microphone array. The method also includes performing a first directivity adjustment by applying a first set of multiplicative factors to the signals to generate a first set of ambisonic signals. The first set of multiplicative factors is determined based on a position of each microphone in the microphone array, an orientation of each microphone in the microphone array, or both.

  • Patent number: 10120638
    Abstract: Example systems, apparatus, and methods receive audio information including a plurality of frames from a source device, wherein each frame of the plurality of frames includes one or more audio samples and a time stamp indicating when to play the one or more audio samples of the respective frame. In an example, the time stamp is updated for each of the plurality of frames using a time differential value determined between clock information received from the source device and clock information associated with the device. The updated time stamp is stored for each of the plurality of frames, and the audio information is output based on the plurality of frames and associated updated time stamps. A number of samples per frame to be output is adjusted based on a comparison between the updated time stamp for the frame and a predicted time value for play back of the frame.
