  • Generation of video transitions on an auxiliary bus using a video switcher
    Patent number: 8605220
    Abstract: A mix-effects bank architecture of a video switcher having a plurality of video processing units; and an internal switcher routing matrix. The internal switcher routing matrix routing, a video source currently providing a video feed to an auxiliary output and a desired new source for the auxiliary output to a video processing unit that is not contributing towards video processing and routing an output of said video processing unit to said auxiliary output. The video processing unit that is not contributing towards video processing performs a transitional effect for the auxiliary output.

  • Combustion catalyst
    Patent number: 6156081
    Abstract: The invention relates to combustion catalyst compositions which when blended into liquid hydrocarbon-base fuels reduce deposits in fuel combustion systems, inhibit corrosion in fuel systems and facilitate a more efficient oxidation of fuel. The combustion catalyst compositions comprise a surface-active/emulsifier agent, a lubricating oil and a liquid saturated hydrocarbon having the general formula C.sub.n H.sub.2n+2 wherein n is from 14 to 17.
