  • Systems and methods for application based interception of SSL/VPN traffic
    Patent number: 9497198
    Abstract: A method for allowing or denying, by an appliance, access to a resource by an application on a client via a virtual private network connection includes basing the decision to allow or deny access on identification of the application. The appliance intercepts a request from an application on a client on a first network to access via a virtual private network connection a resource on a second network. The appliance identifies the application and associates with the intercepted request an authorization policy based on the identity of the application. The appliance determines, using the authorization policy and the identity of the application, to either allow or deny access by the application to the resource.

  • Copper-indium-gallium-chalcogenide nanoparticle precursors for thin-film solar cells
    Patent number: 9466743
    Abstract: Nanoparticles containing IUPAC group 11 ions, group 13 ions and sulfur ions are synthesized by adding metal salts and an alkanethiol in an organic solvent and promoting the reaction by applying heat. Nanoparticles are formed at temperatures as low as 200° C. The nanoparticles may be thermally annealed for a certain amount of time at a temperature lower than the reaction temperature (usually ˜40° C. lower) to improve the topology and narrow the size distribution. After the reaction is complete, the nanoparticles may be isolated by the addition of a non-solvent and re-dispersed in organic solvents including toluene, chloroform and hexane to form a nanoparticle ink. Additives may be incorporated in the reaction solution to tailor the final ink viscosity.

  • Quantum Dots Stabilized With A Metal Thiol Polymer
    Publication number: 20160289552
    Abstract: A composition of matter comprises a plurality of quantum dots and a metal thiol polymer that acts to stabilize the quantum dots. In certain embodiments, the metal thiol polymer is a zinc thiol polymer. The zinc thiol polymer may be a zinc alkanethiolate. The zinc alkanethiolate may be zinc dodecanethiolate (Zn-DDT). A composition comprising a plurality of quantum dots and a metal thiol polymer may be formulated with one or more additional polymers as a quantum dot-containing bead or as a quantum dot-containing composite material—e.g., a multilayer film.

  • UPGRADEABLE LIGHTING FIXTURE
    Publication number: 20160286619
    Abstract: A lighting fixture includes an outer frame, a solid-state light source, a lens, and a sensor module connector. Driver circuitry is coupled to the outer frame and provides one or more drive signals for powering the light source. The lens is supported by and attached to the outer frame. The solid-state light source is mounted to the outer frame and at least partially surrounded by the lens, such that at least a portion of the light provided by the solid-state light source is transmitted through the lens towards an area of interest. The sensor module connector is mounted to the outer frame and configured to accept a connector from a sensor module such that when the sensor module is installed in the lighting fixture, a surface of the sensor module faces the area of interest towards which light from the solid-state light source is provided.

  • LED Cap Containing Quantum Dot Phosphors
    Publication number: 20160268486
    Abstract: An LED device has a cap containing one or more quantum dot (QD) phosphors. The cap may be sized and configured to be integrated with standard LED packages. The QD phosphor may be held within the well of the LED package, so as to absorb the maximum amount of light emitted by the LED, but arranged in spaced-apart relation from the LED chip to avoid excessive heat that can lead to degradation of the QD phosphor(s). The packages may be manufactured and stored for subsequent assembly onto an LED device.
