  • Patent number: 8314046
    Abstract: Heterogeneous catalyst systems, methods of making these systems, and methods of using these systems, wherein catalytically active gold is deposited onto composite support media. The composite support media is formed by providing nanoporous material on at least a portion of the surfaces of carbonaceous host material. In representative embodiments, relatively fine, nanoporous guest particles are coated or otherwise provided on surfaces of relatively coarser activated carbon particles. Catalytically active gold may be deposited onto one or both of the guest or host materials either before or after the guest and host materials are combined to from the composite host material. PVD is the preferred catalyst system of depositing gold.

  • Publication number: 20120285019
    Abstract: Method for making a layered dental restoration, the method includes providing a solid structure (e.g., a die or a dental core, such as a fully sintered ceramic dental core) having a desired outer shape, and applying a first slurry to the solid structure to form a first free form layer on the solid structure. The method further include solidifying the first free form layer on the solid structure, and machining the solidified first free form layer to a desired shape to form a first article comprising the solid structure and a first shaped layer. The method can further include applying, solidifying, and machining a second layer in a similar way to form a second article comprising the solid structure, the first shaped layer, and a second shaped layer. The free form layers need not be exposed to a high temperature prior to being machined.

  • Publication number: 20120287677
    Abstract: Optical constructions use a low index of refraction layer (120) disposed between a low absorption layer (101) and a high absorption layer (103) to increase confinement of light to the low absorption region of the optical constructions. Low index layers can be used in optical constructions that have multi-tiered light confinement. In these constructions, a first tier of reflection is provided when light is reflected at the surface of a low index optical film which is disposed directly or indirectly on a light guide (110). A second tier of reflection occurs at the surface of a light redirecting film having appropriately oriented refractive structures.

  • Publication number: 20120286691
    Abstract: Supplying pulsed current to a load involves repeatedly driving an electrical load between successive active and idle states via a regulator that includes a switched mode power supply. The regulator receives input current from a direct current power source and provides output current to at least an energy storage device in the idle states of the electrical load. The energy storage device is coupled to the load and the regulator. Output current is provided from both the regulator and the energy storage device to the electrical load in the active states of the electrical load. A storage capacity of the energy storage device is selected so that a duty cycle of the input current is greater than a duty cycle of the output current.

  • Patent number: 8304976
    Abstract: A lighting system provides a system optical output, such as white light, as a function of an applied electrical signal. The system output can be characterized by a color temperature or other measure that represents the color or output spectrum of the output. The system is designed so that the color temperature changes as a function of the applied electrical signal. The changes in color temperature are at least in part a result of a phenomenon known as “current crowding”.
