  • Method for preventing screen capture
    Patent number: 11356580
    Abstract: A screen capture prevention method includes serving a single-color, DRM-protected video clip for display as a background for a document on a web browser. The document is processed to render its background color as transparent. Content of the document is viewable over the contrasting video clip background. When a screen capture event is detected, the video clip is changed to a same color as the content of the processed document, rendering the content indistinguishable from the background while the screen capture event is active.

  • Method and apparatus for the production of carbon fibre reinforced aluminum matrix composite wires
    Patent number: 9816167
    Abstract: The invention relates to a method for the production of carbon fiber reinforced aluminum matrix composite wires by drawing carbon fibers through molten salt and molten aluminum in such a way that the molten aluminum and the molten salt are spatially separated, and the carbon fibers are drawn through first the molten salt, then the molten aluminum separated from it. The invention further relates to an apparatus for the implementation of the method.

  • Method to produce monotectic dispersed metallic alloys
    Patent number: 8500925
    Abstract: The invention relates to a method for producing monotectic alloys with finely dispersed and homogeneously distributed second phase particles from two or more starting metals or alloys, in which the two or more metals or alloys are melted together or separately and the two or more, practically immiscible liquid metallic alloys are mixed to disperse the alloy of lower volume ratio with the other alloy of higher volume ratio, then the system is cooled below the eutectic temperature. The characteristic feature of the method is that at least one of the starting alloys contains stabilizing solid particles.
