  • Patent number: 11176196
    Abstract: In some implementations, a computing device may perform a method for providing a unified pipeline for media metadata to converge disparate schemas and data structures into a global unified graph. The method includes receiving media metadata from disparate media sources that may each have a different metadata schema that defines the structure and attributes of the metadata provided by each media source. The computing device may compare media metadata received from the different media sources to determine that metadata received from the different media sources correspond to similar, or the same, media entities (e.g., songs, movies, books, etc.). The metadata for the similar media entities may then be combined into a global unified graph that may include metadata attributes and/or values of the metadata received from the various media sources.

  • Patent number: 8978481
    Abstract: Pairs of acoustic transducers positioned at different radial distances in a conduit are used to measure travel times of acoustic signals in opposite directions and inclined to the direction of a fluid flow in the borehole. These contrapropagation measurements are used to estimate fluid velocity and volumetric flow rates of the fluid components in the conduit.

  • Patent number: 7694734
    Abstract: A method and apparatus are provided for insulating electrical connections to a resonator from fluid downhole under extreme pressure and temperature conditions downhole. The method and apparatus provide a pliable insulator that maintains electrical isolation between a resonator electrical connection during exposure to high pressures downhole. The insulator is substantially chemically non reactive so that the insulator maintains electrical isolation between the resonator electrical connections during exposure to fluids downhole. The insulator has a thermal coefficient of expansion in a range so that the insulator maintains electrical isolation between the resonator electrical connections during exposure to high temperatures downhole.

  • Patent number: 7647965
    Abstract: A method and apparatus are provided for insulating electrical connections to a resonator from fluid downhole under extreme pressure and temperature conditions downhole. The method and apparatus provide a pliable insulator that maintains electrical isolation between resonator electrical connections during exposure to high pressures downhole. The insulator is evacuated or placed in a vacuum prior to curing to remove bubbles from the insulator material. The insulator is then heat cured. The insulator is substantially chemically non reactive so that the insulator maintains electrical isolation between the resonator electrical connections during exposure to fluids downhole. The insulator has a thermal coefficient of expansion in a range so that the insulator maintains electrical isolation between the resonator electrical connections during exposure to high temperatures downhole.
