  • Patent number: 8684662
    Abstract: A ring segment for a gas turbine engine includes an outer panel defining a structural body for the ring segment. An outer side of an inner panel is attached to an inner side of the outer panel at an interface, and an inner side of the inner panel defines a portion of a hot gas path through the gas turbine engine. An outer side of the outer panel, opposite from the interface, is in communication with a source of cooling air. A plurality of impingement holes extend through the outer panel from the outer side to the inner side of the outer panel for directing impingement air to the outer side of the inner panel. The outer and inner panels define a plurality of flow channels at the interface for effecting convective cooling of the outer panel along the flow channels between the outer and inner panels.

  • Patent number: 8516585
    Abstract: In one embodiment, a method for detecting malicious software agents, such as domain-flux botnets. The method applies a co-clustering algorithm on a domain-name query failure graph, to generate a hierarchical grouping of hosts based on similarities between domain names queried by those hosts, and divides that hierarchical structure into candidate clusters based on percentages of failed queries having at least first- and second-level domain names in common, thereby identifying hosts having correlated queries as possibly being infected with malicious software agents. A linking algorithm is used to correlate the co-clustering results generated at different time periods to differentiate actual domain-flux bots from other domain-name failure anomalies by identifying candidate clusters that persist for relatively long periods of time.

  • Patent number: 8294116
    Abstract: Optical beam modulation is accomplished with the aid of a semiconductive nanomembrane, such as a silicon nanomembrane. A photocathode modulates a beam of charged particles that flow between the carbon nanotube emitter and the anode. A light source, or other source of electromagnetic radiation, supplies electromagnetic radiation that modulates the beam of charged particles. The beam of charged particles may be electrons, ions, or other charged particles. The electromagnetic radiation penetrates a silicon dioxide layer to reach the nanomembrane and varies the amount of available charge carriers within the nanomembrane, thereby changing the resistance of the nanomembrane. As the resistance of the nanomembrane changes, the amount of current flowing through the beam may also change.

  • Patent number: 8245951
    Abstract: Use of carbon nanotubes (CNTs) in a charge injector to assist in atomizing fuel for engine applications. A CNT charging unit is positioned in front of a fuel injector. A voltage is applied on a CNT coated mesh to charge the fuel stream when it passes. Then the charged stream goes through a grounded metal cage. The fuel is thereby electrostatically charged causing repulsive forces on surfaces of liquid in the fuel resulting in the liquid splitting into droplets.
