  • Patent number: 10596598
    Abstract: Methods and systems are provided for a single element ultrasound transducer. In one embodiment, the ultrasound transducer comprises: a piezoelectric layer, a matching layer, one surface of the matching layer is electrically coupled to a top surface of the piezoelectric layer and another surface of the matching layer forms a signal pad within a front face of the ultrasound transducer, and a base package electrically coupled to a bottom surface of the piezoelectric layer, the base package extending horizontally and laterally to form a back face of the ultrasound transducer parallel to the front face of the ultrasound transducer, and extending vertically relative to the back face of the ultrasound transducer to form a ground pad within the front face of the ultrasound transducer. In this way, the transducer can work robustly and may be automatically mounted to a flat substrate with printed circuit.

  • Patent number: 10585855
    Abstract: A technique for managing a file system includes arranging a first set of multiple metadata elements at a first set of block locations and arranging a second set of multiple metadata elements at a second set of block locations. Each of the first set of metadata elements is related to a respective one of the second set of metadata elements to form a respective pair of metadata elements that the file system is configured to update together. The technique further includes backing the first set of block locations and the second set of block locations together on a single RAID stripe, such that updating each pair of metadata elements is achieved using a single stripe write.

  • Patent number: 10393146
    Abstract: A flexible metal foil can be fixed on the inside part of a variable pitch vane control ring of a turbojet compressor, so as to close all through holes in which lever pins and their surrounding bushes are housed. As a result, the foil can retain the shank of the bush if the bush breaks. The use of such foil does not impose the development of a new model of control ring and its impact on the mass is small enough so that it does not affect engine performances. Therefore it avoids problems related to the breakage of bushes without having to make major changes to the existing system.

  • Publication number: 20190218929
    Abstract: A device for controlling variable-pitch turbomachine members such as stator vanes, wherein the movement of a control mechanism is imparted to a ring that rotates the levers for pivoting the vanes about a stator, and takes place with a possible change in the length of the bottle screw connecting the ring to the control mechanism, thereby allowing the blade pitch angle law to be changed according to the extension of the control device. A greater freedom of adjustment is thus obtained. The device can be useful when a single control mechanism is used for multiple rings arranged side by side, making it possible to have different control laws for the rings.
