Title: Recirculating shade tree blender for a graphics system
Inventor: DREBIN ROBERT A
IPC: G06T15/00
Filed: 2001-08-17
Abstract: A graphics system including a custom graphics and audio processor produces exciting 2D and 3D graphics and surround sound. The system includes  a Graphics and audio processor including a 3D graphics pipeline and an audio digital signal processor. To achieve multi-texturing, conventional graphics renderin g systems typically rely on multiple rendering passes or require multiple serial/parallel texture-retrieval/processing circuits which occupy additiona l chip real-estate and exacerbate memory arbitration problems. To solve this proble m and to provide an enhanced repertoire of multi-texturing capabilities, a relatively low chip-footprint, versatile texture environment (TEV) processing subsystem  is implemented in a pipelined graphics system by utilizing a flexible API and a hardware-accelerated programmable texture blender/shader arrangement that circulates computed color and alpha data over multiple texture blending/shading cycles (stages). The texture-environment subsystem combines per-vertex lighting, textures and constant (rasterized) colors to form computed pixel color prior  to fogging and final pixel blending. Blending operations for color (RGB) and alpha components are independently processed within the TEV subsystem by a single sub-blend unit consisting of a set of color/alpha-combiner (shader) hardware  that is reused over multiple processing stages to combine multiple textures. A set o f four selectable current-color input/output registers which are shared among all stages is provided at the output of the sub-blend unit to temporarily store computed color results and to pass computed color between stages. Arguments for blending stage operations can be selected from: the four current-color registers, rasterize d color (diffuse or specular), texture, the alpha components of the above colors, an d 0 or 1. Up to sixteen independently programmable consecutive stages, forming a chain  of    78   blending operations, are supported for applying multiple textures to a singl e object in a single rendering pass.

IPC: H04N1/405
Filed: 2000-10-06
Abstract: Provided are systems and methods for rendering a halftone image (110) on a medium. The original continuous tone image (100) is divided into a plurality of pixels (202) and each pixel is representative of an area of the original image. Each pixel may comprise a plurality of dots (203) and a level represents the number of dots to be placed within the pixel. Level also refers to an amount of ink which is placed on a medium. Each level is represented as a dot placement and potential dot placements are stored in a data structure (220). The data structure is large enough to hold the potential levels of one or more pixels. Thus, more than one pixel can be processed and rendered at the same time. The data structure is referenced by the levels of the pixel to be printed and the dot placement stored at the referenced level is output to the output device (50).

Abstract: A vestigial sidehand (VSB) modulation minimum output (MOE) pro-equalizer operating on a received ATSC 8-VSB DTV signal includes one or more of an adaptive food-forward filter and an adaptive feedback filter each utilizing only reel adaptive coefficients, with the direct term for the overall filter constrained to unity to remove one degrees of filter parameterization freedom. Adaptation of the filter(s) is based on minimizing a blind energy cost function, and is independent of adaptation of a conventional adaptive channel equalizer. The pre-equalized signal is passed to the conventional adaptive equalizer for channel equalization utilizing DFE, IIR-CMA, etc., resulting in performance improvements including faster convergence and greater robustness with relatively small implementation costs,

Abstract: L'invention concerne un système de capteurs placé sous unité de commande qui mesure et affiche de manière répétitive la concentration totale d'ammoniac. On peut utiliser ce système dans une structure de cathéter ou avec un mécanisme de dérivation. Les capteurs utilisés avec cathéter peuvent fonctionner en liaison avec une zone périphérique du système vasculaire dans le corps humain. Les mesures répétitives sont soumises à une procédure de filtrage en moyenne mobile, et les valeurs ainsi filtrées de la concentration sont affichées numériquement et graphiquement. L'unité de commande calcule le temps de montée de la concentration et compare cette valeur à un seuil de temps de montée introduit par le praticien. On peut également introduire dans le système des valeurs de seuil pour la concentration, et le système fournit à la fois des alarmes correspondant aux écarts par rapport aux seuil du temps de montée ou de la concentration, et une indication tenant lieu d'alerte visuelle montrant que la concentration passe d'une mesure filtrée à une autre.
