  • Patent number: 8659589
    Abstract: Methods and computer-readable media for displaying two-dimensional objects on a display device are disclosed. Rendering requests are received from an application to render two-dimensionally modeled graphics to a display device. Primitive geometries of drawing calls of the rendering requests are tessellated into sequences of triangles. The vertices of the triangles are mapped to a vertex buffer along with an index to identify associated constant data. Batching operations store and communicate calls and mapped data to a graphics processing unit by way of a three-dimensional rendering application program interface. Constant data associated with the mapped data are indexed and appended together in a constant buffer, thereby allowing drawing calls to be coalesced. A staging buffer and a staging texture are provided for batching text anti-aliasing operations. Shader fragments are precompiled and organized by way of a predetermined lookup table.

  • Patent number: 6540862
    Abstract: This invention relates to the extrusion coating of polyethylene terephthalate (PET) onto paperboard. Such structures of this type, generally, provide an enhanced film adhesion of the PET onto the paperboard, while reducing the coat weights of the PET.

  • Patent number: 6045656
    Abstract: This invention relates to a method for producing anti-counterfeit paper. Such processes of this type, generally, add a certain percentage of wood fiber lumens which have been loaded with one or more fluorescent agents. These wood fiber lumens would look normal under regular light, but will glow when exposed to various manners of radiation.

  • Patent number: 5679221
    Abstract: This invention relates to recently developed systems which produced bleached recycled fibers from high lignin content recovered paper materials such as old corrugated containers and old newspapers. Such systems of this type, generally, use chemical digestion (e.g., the kraft process) to reduce the lignin content prior to bleaching. Since recovered paper materials normally have high levels of aluminum, which are derived from the paper sizing and pH control chemical, aluminum sulfate; and since soluble aluminum causes scaling of evaporators in the kraft digestion-chemical recovery cycle, there is a need for a means to remove soluble aluminum from the recovered paper materials prior to digestion.
