Abstract: Methods for upgrading heavy aromatic waste streams, such as polystyrene, to chemical feedstocks are disclosed. The process involves feeding waste streams to a first pyrolysis zone followed by hydrogenation. The hydrogenation effluent is processed to recover ethylene, propylene, benzene, ethylbenzene, or their precursors. Optionally, the effluents are separated into light and heavy streams. The light stream from the first pyrolysis effluent is sent to hydrogenation, while the heavy stream is either removed, recycled to the first pyrolysis zone, or fed to a second pyrolysis zone. The light stream from the hydrogenation effluent is processed to recover the same chemicals, and the heavy stream is similarly managed. If present, the second pyrolysis effluent is separated into light and heavy streams, with the light stream processed to recover chemicals and the heavy stream managed as before.

Abstract: The Invention is for aiding a person to identify the probable name of a TV or Movie actor by pointing the device at the full face of the actor and clicking a button which captures the image of the actor and compares the image against a database using facial recognition software. The list of probable answers is then either displayed on the device screen or on the TV screen next to the actor that was requested to be identified.

Abstract: An occlusion culling circuit for use in a graphics computer receives graphics primitives data including x and y coordinates for each pixel, a z depth value, and r, g, b, and a or index color data. For each group of primitives, the graphics computer scans the primitive and determines a volume which completely bounds the primitive. The z depth values for the pixels comprising the bounding volume are then compared by the occlusion culling circuit to the depths of the pixels in the already rendered primitives to determine whether any pixels in the incoming primitive are visible. If no pixels are visible, the occlusion culling circuit clears the result register and receives the next graphics primitive. If, on the other hand, one or more pixels is visible, the occlusion culling circuit completely renders the primitives bounded by the bounding volume.
