  • Patent number: 10819576
    Abstract: A device receives policy information indicating a policy to be implemented for an application hosted by multiple cloud domains, and receives, from the multiple cloud domains, different application resource tags and addresses associated with the application. The device maps the different application resource tags to a generic identifier, and associates the policy with the generic identifier and with the addresses associated with the application. The device provides, based on associating the policy with the generic identifier and with the addresses associated with the application, the policy to the multiple cloud domains to permit the multiple cloud domains to implement the policy.

  • Publication number: 20190297103
    Abstract: A device receives network segment information identifying network segments associated with a network, and receives endpoint host session information identifying sessions associated with endpoint hosts communicating with the network. The device generates, based on the network segment information and the endpoint host session information, a data structure that includes information associating the network segments with the sessions associated with the endpoint hosts. The device updates the data structure based on changes in the sessions associated with the endpoint hosts and based on changes in locations of the endpoint hosts within the network segments, and identifies, based on the data structure, a particular endpoint host, of the endpoint hosts, that changed locations within the network segments. The device determines a threat policy action to enforce for the particular endpoint host, and causes the threat policy action to be enforced, by the network, for the particular endpoint host.

  • Publication number: 20190297094
    Abstract: A device receives information identifying a specific host threat to a network, where the information includes a list of network addresses associated with the specific host threat. The device identifies network elements, of the network, associated with the specific host threat to the network, and determines a network control system associated with the identified network elements. The device determines a policy enforcement group of network elements, of the identified network elements, that maps to the list of network addresses associated with the specific host threat, where the network control system is associated with the policy enforcement group of network elements. The device determines a threat policy action to enforce for the specific host threat, and causes, via the network control system, the threat policy action to be enforced by the policy enforcement group of network elements.

  • Patent number: 9480375
    Abstract: The invention disclosed herein provides for high particle removal rate and/or heat transfer from surfaces. The device removes particulate matter from a surface using a bounded vortex generated over the surface, with suction in the vortex center and jets for blowing air along the periphery. The jets are tilted in the tangential direction to induce vortex motion within the suction region. The vortex is said to be bounded because streamlines originating in the downward jets are entrained back into the central vortex.

  • Patent number: 8695156
    Abstract: The aero-acoustic duster invention disclosed herein provides for high particle removal rate from surfaces with low energy expenditure relative to competing vacuum-based devices. The device removes particulate matter from a surface using a two-step process: 1. Acoustic radiation is used to break the adhesive bonds between dust and the surface, forcing particles into a mode where they continuously bounce up and down on the surface; and, 2. A bounded vortex is generated over the surface, with suction in the vortex center and jets for blowing air along the periphery. The jets are tilted in the tangential direction to induce vortex motion within the suction region. The vortex is said to be bounded because streamlines originating in the downward jets are entrained back into the central vortex.

  • Patent number: 6424923
    Abstract: A method for computing three dimensional unsteady flows about an object. An allowable error is established for the vorticity term calculations, and object geometry is provided giving surface points on an object and a region of interest. A mesh is established incorporating points on the object. Initial flow conditions are set at the surface. Vorticity values that will satisfy boundary conditions are set at the provided surface points. A new mesh is established incorporating the provided points and other points in the region of interest. Boxes are generated containing the provided points and other points. Velocities and pressures at each point are calculated from the flow conditions, vorticity values and boundary conditions., A time variable is incremented and each point is moved by applying the calculated velocity. Vorticity at each point is then recalculated. The method is iterated starting with the step of satisfying boundary conditions until the incremented time variable exceeds a predetermined value.
