  • Patent number: 12253989
    Abstract: A versioned dataset is managed. An updated versioned dataset is created by applying a structured query to a specific version of multiple versions of the versioned dataset stored in the backing dataset. Data of the versions including the specific version remain unchanged. A versioned dataset catalogue is updated to include in association with the updated dataset version, the structured query and lineage indicating that the updated versioned dataset includes a successor of the specific version. An affiliation encoding associated with the updated versioned dataset indicating which data of the updated versioned dataset matches data of the specific version and which data of the updated versioned dataset is deleted relative to data of the specific version, is updated. A database view of the updated versioned dataset is generated by selecting rows and projecting columns of the backing dataset corresponding to the updated versioned dataset according to the affiliation encoding.

  • Patent number: 11533689
    Abstract: A system and method for controlling dynamic transmit power in a mesh network are disclosed. Distributed power transmit management methodology that implements transmission power management based on a comparison of signal to noise ratios from received beacon packets is used on a peer-to-peer basis. Embodiments work to keep all nodes accessible, dynamically adaptable to constant changes in the network, maximize frequency reuse, and reduce power requirements to maximize network performance while minimizing interference.

  • Patent number: 9979635
    Abstract: Computer networks with multiple nodes are often required to deliver packets to all nodes in the network, commonly referred to as “flooding.” Flooding is used to deliver multicast and broadcast packets generated by application, network and other layers of the networking stack. Flooding can be done very reliably but less efficiently via node to node “unicast” transmissions, or very efficiently but less reliably via “broadcast” transmissions. In order to balance reliability with efficiency, this invention defines a threshold for the number of neighboring nodes as seen by a given node prior to a flooding operation to determine whether data should be unicast or broadcast. Below that threshold, unicast is used; at or above that threshold, broadcast is used. The invention also incorporates knowledge of nodes seen in turn by neighbor nodes as part of this decision.

  • Publication number: 20150271086
    Abstract: Networks based on Internet Protocol (IPv4) employ an administrative Address Resolution Protocol (ARP) to convert logical IP addresses into physical Ethernet media access control (MAC) addresses. These queries address the entire network, and in very large networks, they contribute substantially to network traffic. This invention identifies ARP packets in a large, dynamic network and uses various means to minimize their broadcast throughout the network. This results in optimized network performance.

  • Patent number: 9001645
    Abstract: Traditional computer networks have been designed with the need for highly reliable packet delivery. This is largely handled by a centrally managed simple send-acknowledge protocol. In a highly dynamic mesh network, these methods are inadequate to ensure the most reliable packet delivery. This invention uses the natural redundancy of routes in a mesh and other techniques to increase the reliability of a network, even as the paths to any given node are dynamic in nature.

  • Publication number: 20150055471
    Abstract: The protocol determines the quality of each node to node link(s), based on an exponentially weighted moving average of the time each packet spends within the network node. Once determined, that quality of link is then mapped into the physical QoS resources of the networking hardware in use (within the network). Packets destined for higher quality links will see an upgrade of their QoS rating, while packets destined to lower quality links will see a downgrade of their QoS rating. That adjustment permits the higher quality links to be processed before the lower quality links resulting in more efficient and complete communications in the network. Poorer quality links will no longer act as roadblocks to the higher quality packets.

  • Patent number: 8555866
    Abstract: An injection gate (44,144,244,344) for high pressure, high velocity secondary fluid for admixture of an atomized spray (80,180) thereof with another or primary fluid that atomizes the other fluid. The secondary fluid may be an accelerant and the primary fluid may be a low pressure fuel/air mixture in a fuel injection arrangement for an internal combustion engine. An injection billet (10,110,210,310) for an engine is interposed between the carburetor (12) and the manifold (14), with an array of such injection gates (44,244,344) paired with an array of fuel/air gates (34,234,334) about an aperture coinciding with a throttle bore (60,160,260,360) and evenly balancing the spray about the throttle bore, creating a halo effect of atomized admixture of accelerant/fuel. The injection of accelerant is directed sharply downwardly toward the center of the bore and through the injected fuel stream, atomizing the fuel thereof for a high efficiency boost of horsepower.
