  • Patent number: 10366027
    Abstract: A method for steering data for an I/O write operation includes, in response to receiving the I/O write operation, identifying, at an interconnect fabric, a cache of one of a plurality of compute complexes as a target cache for steering the data based on at least one of: a software-provided steering indicator, a steering configuration implemented at boot initialization, and coherency information for a cacheline associated with the data. The method further includes directing, via the interconnect fabric, the identified target cache to cache the data from the I/O write operation. The data is temporarily buffered at the interconnect fabric, and if the target cache attempts to fetch the data while the data is still buffered at the interconnect fabric, the interconnect fabric provides a copy of the buffered data in response to the fetch operation instead of initiating a memory access operation to obtain the data from memory.

  • Patent number: 10293522
    Abstract: A multi-piece mold for use in a method for making a slurry distributor includes a plurality of mold segments adapted to be removably secured together. The mold segments are configured such that, when the mold segments are assembled together, the assembled mold segments define a substantially continuous exterior surface adapted to be a negative image of an interior flow region of a slurry distributor molded thereupon. Each mold segment has a maximum cross-sectional area in a plane substantially transverse to a direction of movement of the mold segment along a removal path out of a respective opening of the molded slurry distributor. The maximum cross-sectional area of each mold segment is up to about 150% of the smallest area of the interior flow region of the molded slurry distributor through which the mold segment traverses when moving along the respective removal path.

  • Patent number: 5630418
    Abstract: A noise controller for use in a probe in a hand held ultrasonic Doppler fetal heart beat detection and monitoring system where the probe includes a crystal for generating an input signal as a function of the ultrasonic energy in received ultrasonic wave and a detector for generating a first signal from the input signal. The noise controller comprises a volume controller for receiving the first signal and for processing the first signal to produce an analog signal as the output of the probe. A detector generates a second signal whenever break noise is detected in the first signal. A muting circuit immediately lowers the amplitude of the analog signal upon detection of break noise by the detector thereby substantially attenuated in the analog signal the break noise which occurred in the first signal.

  • Patent number: 4999833
    Abstract: A communications system utilizes artificial intelligence to select connectivity paths among various locations in a communications network. An embodiment shown is that of a packet radio network, wherein an artificial intelligence module, located at one or more of the radio sites in the network, applies a set of heuristic rules to a knowledge base obtained from network experience to select connectivity paths through the network. The artificial intelligence module comprises an inference engine, a memory for storing network data obtained from a radio receiver and transmitting it to the inference engine, a memory connected to the inference engine which stores a set of heuristic rules for the artificial intelligence system, and a knowledge base memory which stores network information upon which the inference engine draws. The knowledge base memory is also capable of feeding back network information to the rule base memory, which can thus update its rules.
