  • Patent number: 10489159
    Abstract: Decompressing sliding window compressed data requires reference to previously decompressed character sequences. Previously decompressed data is stored in a history buffer to satisfy these ‘back references.’ As each decompressed/decoded character is emitted, it is stored in this history buffer. Thus, for each decompressed character that is emitted, the history buffer may need to be accessed at least twice—once to retrieve the backreference, and once to store the emitted character. A pipeline architecture is disclosed that stores decompressed characters in a write queue that coalesces eight or more emitted characters before they are stored in the history buffer memory. This reduces collisions between accessing the history buffer memory to retrieve the backreferences and the storing of the emitted character. This also allows the use of a single-ported memory which is less expensive than a multi-ported memory.

  • Patent number: 10441798
    Abstract: Implantable medical systems enter an exposure mode of operation, either manually via a down linked programming instruction or by automatic detection by the implantable system of exposure to a magnetic disturbance. A controller then determines the appropriate exposure mode by considering various pieces of information including the device type including whether the device has defibrillation capability, pre-exposure mode of therapy including which chambers have been paced, and pre-exposure cardiac activity that is either intrinsic or paced rates. Additional considerations may include determining whether a sensed rate during the exposure mode is physiologic or artificially produced by the magnetic disturbance. When the sensed rate is physiologic, then the controller uses the sensed rate to trigger pacing and otherwise uses asynchronous pacing at a fixed rate.

    Abstract: An embodiment of a tool assembly includes a robotic assembly, a tool mount, and a non-axisymmetric deep rolling tool. The robotic assembly includes a plurality of linear arms connected in series between a base end and a working end. Adjacent ones of the plurality of arms are connected via a corresponding plurality of multi-axis joints such that the working end is articulated by movement of one or more of the plurality of arms relative to one or more of the plurality of multi-axis joints. The tool mount is connected to one of the linear arms or one of the multi-axis joints at the working end of the robotic assembly. The non-axisymmetric deep rolling tool is connected to the tool mount, and includes a spring-loaded shaft assembly disposed along a first axis. A hub has an upper hub portion adjacent to the distal end of the spring-loaded shaft assembly aligned with the first axis, and a lower hub portion extending along a second axis, forming a nonzero angle relative to the first axis.

  • Publication number: 20110189924
    Abstract: A method of machining a rotor disk includes the step of detecting accessible contact areas on a rotor surface and corresponding abrasive disk orientations at contact points within that contact area. The detected accessible area and orientations are then utilized to map a machining path and corresponding abrasive disk movements. Machine tool executable instructions are generated using the mapped machining path and corresponding abrasive disk movement for removing material on a rotor surface between two airfoils.

  • Patent number: 7967659
    Abstract: A method of manufacturing an integral bladed rotor is disclosed. The method includes calculating a cutting path in an area of a blank between adjacent blade locations to approximate contours of adjacent blades. A cutter is plunged into the area at an initial angle and depth that extends from an outer perimeter to the blank to an inner perimeter of the blank, in one example. The blade roots extend from the inner perimeter, and the blade tips terminate near the outer perimeter. The cutter is plunged into the area at an original angle that, in one example, is different than the initial angle. The cutter is rotated about an axis in a spiral-like fashion as the cutter extends further into the blank, along the cutting path.

  • Patent number: 7927069
    Abstract: A rotor blade assembly includes a slot for mounting a rotor blade that extends partially through a rotor disk and a continuous uninterrupted hoop seal that extends about the circumference of the rotor disk. The rotor disk includes an integrally formed seal that includes at least one knife edge disposed concentrically about the rotor disk. The slot receives a root portion of a rotor blade but does not extend through the seal. As the seal remains an uninterrupted full hoop about the circumference of the rotor disk, additional rigidity and strength are realized. The increased rigidity and strength provided by the full hoop structure provides for the reduction in material and physical dimensions without compromising desired performance of the seal.
