  • Patent number: 12104699
    Abstract: A representative seal system (such as a seal system for a turbopump of a rocket engine) automatically adjusts a balance ratio of a seal. The system can include a ring element encircling an axis. A front side of the ring element contacts a revolving surface to form a seal with the revolving surface. The front side can include a stepped surface having two or more steps. Each step includes a sealing surface configured to contact the revolving surface to form a sealing area that is different from a sealing area of each other sealing surface. Each step is positioned and configured to wear away during operation of the machine to expose an underlying surface to the revolving surface, to change the sealing area and the balance ratio of the seal. A representative method of operating a turbomachinery system includes changing the balance ratio of a seal while rotating a rotor.

  • Patent number: 10303385
    Abstract: Modifying initialization data for a memory array of a circuit design can include providing, using a processor, portions of an incoming stream of data for initializing the memory array to emulation objects of a memory array emulator. The memory array emulator is configured to emulate an implementation of the memory array and the emulation objects represent block random access memories (block RAMs) of the memory array. Using the processor, the data can be formatted using the emulation objects to generate initialization data, wherein the data is formatted based upon configuration settings of the block RAMs emulated by the respective emulation objects. A configuration bitstream can be updated, using the processor, with the initialization data.
