Patent number: 9979635Abstract: 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.Type: GrantFiled: December 7, 2016Date of Patent: May 22, 2018Assignee: Rajant CorporationInventors: Paul R.

Publication number: 20150271086Abstract: 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.Type: ApplicationFiled: March 24, 2014Publication date: September 24, 2015Applicant: Rajant CorporationInventors: Paul Hellhake, David Acker, Joe Parks

Patent number: 9001645Abstract: 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.Type: GrantFiled: December 7, 2012Date of Patent: April 7, 2015Assignee: Rajant CorporationInventors: Paul R.

Publication number: 20150055471Abstract: 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.Type: ApplicationFiled: November 11, 2013Publication date: February 26, 2015Applicant: Rajant CorporationInventors: Paul R.

Patent number: 8555866Abstract: 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.Type: GrantFiled: December 3, 2008Date of Patent: October 15, 2013Inventors: David Acker, Steven Wilson, James Hobensack

Patent number: 8456571Abstract: Techniques are described for performing aspect ratio transformation. Frames of image data from each of one or more input sources are received. A first set of one or more options, including an input aspect ratio, is associated with a first input source. A set of control parameters is determined for each frame from the first input source in accordance with said first input aspect ratio and an output aspect ratio. Each frame from the first input source is processed in accordance with the control parameters for that frame. The processing includes processing a first image from said first input source having said first input aspect ratio to generate a second image having the output aspect ratio. The processing includes converting the first image having the input aspect ratio to the second image having the output aspect ratio if the first input aspect ratio is different from the output aspect ratio.Type: GrantFiled: February 13, 2008Date of Patent: June 4, 2013Assignee: Broadcast Pix, Inc.Inventors: Benjamin Taylor, David Acker
