  • Patent number: 10613980
    Abstract: A data processing system includes first and second processing nodes and response logic coupled by an interconnect fabric. A first coherence participant in the first processing node is configured to issue a memory access request specifying a target memory block, and a second coherence participant in the second processing node is configured to issue a probe request regarding a memory region tracked in a memory coherence directory. The first coherence participant is configured to, responsive to receiving the probe request after the memory access request and before receiving a systemwide coherence response for the memory access request, detect an address collision between the probe request and the memory access request and, responsive thereto, transmit a speculative coherence response. The response logic is configured to, responsive to the speculative coherence response, provide a systemwide coherence response for the probe request that prevents the probe request from succeeding.

  • Publication number: 20200076208
    Abstract: An energy storage system comprising a main bus, a transfer bus, and a pair of anti-parallel thyristors electrically coupled to the main bus and the transfer bus. The system also includes a first and second group of battery cells electrically coupled to the main bus and the transfer bus, and a switching network including a plurality of switches that selectively connect the first and second groups of battery cells to the main bus and the transfer bus. A controller controls the position of the switches and a bias voltage applied to the first and second thyristors so as to seamlessly transition power from the first group of battery cells to the second group of battery cells when the group of battery cells are being discharged and seamlessly transition power between the first group of battery cells and the second group of battery cells when the battery cells are being charged.

  • Publication number: 20200020459
    Abstract: A method for increasing the MeV hot electron yield and secondary radiation produced by short-pulse laser-target interactions with an appropriately high or low atomic number (Z) target. Secondary radiation, such as MeV x-rays, gamma-rays, protons, ions, neutrons, positrons and electromagnetic radiation in the microwave to sub-mm region, can be used, e.g., for the flash radiography of dense objects.

  • Publication number: 20190245343
    Abstract: A method for detecting a voltage disturbance in a utility having a micro-grid. The method transforms current and voltage measurements into first and second voltage values and first and second current values in a stationary reference frame, and transforms the first and second voltage values and the first and second current values to third and fourth voltage values and third and fourth current values in a rotating reference frame, where the third voltage value defines an average magnitude of the three-phase power signals. The method multiplies the third current value by the third voltage value to obtain an instantaneous power value and multiplies the fourth current value by the third voltage value to obtain an instantaneous volt-ampere reactive (VAR) value. The method opens the switch if the VAR value has a magnitude above a predetermined value and a direction indicating the fault is outside of the micro-grid in the network.

  • Patent number: 10360338
    Abstract: A computer-implemented method for extracting a capacitance for a target wire of an integrated circuit includes receiving a design of the integrated circuit having a plurality of wiring layers and selecting a target wire to perform the capacitance extraction. The method further includes determining a first adjacent wiring layer and a second adjacent wiring layer and removing a first subset and a second subset of a plurality of non-adjacent wiring layers from the plurality of wiring layers. The method includes approximating a first plate to be used in the extraction based on the first subset of the plurality of non-adjacent wiring layers and approximating a second plate to be used in the extraction based on the second subset of the plurality of non-adjacent wiring layers and performing the extraction of the target wire based on the first and second adjacent wiring layers and the first and second plates.

  • Patent number: 8880416
    Abstract: Systems and methods for creating in a facility on-demand routes for powered industrial vehicles to transport cargo efficiently. In one embodiment, an on-demand route generation module receives receiving a request to move cargo. The module analyzes data about the current location, the current tasking, and the driver availability of PIVs in operation. Based on the information, the module creates an on-demand route through the facility and sends a notification to an assigned PIV to pick up the cargo and carry it on the defined on-demand route.
