  • Publication number: 20200374209
    Abstract: System and method for identifying nodes with packet loss in a wireless communication network. The method comprises a central probe server—establishing a TWAMP session with a plurality of nodes. The central probe server probes the plurality of nodes for packet loss for a time duration ?T and categorizes each of the plurality of nodes as one of violator node and non-violator node. A sectionalisation module retrieves a topology of the at least one violator node. The central probe server probes at least one neighboring node of the at least one violator node for packet loss for the time duration ?T. The sectionalisation module identifies the at least one violator node as one of a silo node and a daisy chain node based on the probe of the at least one neighboring node.

  • Patent number: 9835363
    Abstract: Evaporative heat transfer system. The system includes a substrate and a plurality of substantially parallel, spaced-apart ridges extending from the substrate forming vertical liquid manifolds therebetween. A nanoporous membrane is supported on the ridges and a pump delivers a dielectric fluid across the ridges. The fluid is drawn through the liquid manifolds via capillarity provided by the nanoporous membrane and evaporates to dissipate heat flux through the substrate. A preferred dielectric fluid is pentane. It is preferred that membrane porosity vary across the membrane to tailor thermal resistances to limit temperature rises.

  • Patent number: 9334194
    Abstract: This disclosure provides methods of flash sintering and compositions created by these methods. Methods for sintering multilayered bodies are provided in which a sintered body is produced in less than one minute. In one aspect, each layer is of a different composition, and may be constituted wholly from a ceramic or from a combination of ceramic and metallic particles. When the body includes a layer of an anode composition, a layer of an electrolyte composition and a layer of a cathode composition, the sintered body can be used to produce a solid oxide fuel cell.

  • Patent number: 9088989
    Abstract: Methods and system are provided for managing and monitoring allocation of RF spectrum resources based on time, space and frequency. A network may be enabled to allocate excess spectrum resources for use by other network providers on a real-time basis. Allocated resources may be transferred from one provider with excess resources to another in need of additional resources based on contractual terms or on a real-time purchase negotiations and settlements. A network may be enabled to monitor the use of allocated resources on real-time basis and off-load or allow additional users depending on the spectrum resources availability. Public safety networks may be enabled to make spectrum resources available to general public by allocating spectrum resources and monitoring the use of those resources. During an emergency, when traffic increases on a public safety network, the public safety networks may off-load bandwidth traffic to make available necessary resources for public safety users.

  • Patent number: 8540797
    Abstract: A method to introduce ceramic particles into liquid metal through the polymeric precursor route by cross-linking organic precursor into a hard polymer, which is added to the liquid melt for in-situ pyrolysis of the organic into the ceramic phase. The starting material, the organic, for the above process can be in the form of a liquid or a solid. If it is a solid it is usually dissolved into a solvent to create a liquid form. The organic is then cross linked either directly by a thermal process, by adding a catalyst, or by the well known sol-gel process into a hard polymer. It is this hard polymer which is then pyrolyzed into a high temperature ceramic material by the process outlined above.
