Abstract: A system for controlling the injection of wastewater treatment chemicals into a wastewater treatment stream includes a holding tank for collecting and holding wastewater being treated, a camera positioned for making images of the wastewater in the holding tank, means for automatically making the images of the wastewater in the holding tank at scheduled intervals, means for analyzing the images in order to determine the necessity for injecting wastewater treatment chemicals into the wastewater stream, comprising measuring the size, distribution and number of pixels of differing colors and appearances, such that pixels of differing colors and appearances represent differing moieties in the wastewater stream including unreacted waste products and unreacted wastewater treatment chemicals, and means for injecting wastewater treatment chemicals into the wastewater stream responsive to the analysis of the images indicating the necessity of such injection.

Abstract: A preferred device for producing a composite digital video data stream containing pixel data corresponding to an image to be rendered includes an input mechanism which is configured to receive multiple digital video data streams from graphics pipelines. In response to receiving a first of the multiple digital video data streams, the input mechanism provides a frame of data corresponding to the image to be rendered and inserts pixel data from the multiple digital video data streams into the frame of data, thereby forming at least a portion of the composite digital video data stream.

Abstract: A node of a network for generating image frames comprising a graphics device operable to generate a viewable data set and a non-viewable data set representative of a three-dimensional image frame, and a first output interface operable to transmit the non-viewable data set is provided. A network for generating image frames comprising a plurality of rendering nodes operable to respectively generate a viewable data set and a non-viewable data set, and further operable to transmit the viewable and non-viewable data sets, and a compositor interconnected with the plurality of rendering nodes and operable to respectively receive the viewable and non-viewable data sets from the plurality of rendering nodes and operable to assemble a composite image from the viewable and non-viewable data sets is provided.

Abstract: A dynamic recovery system comprises a plurality of render nodes each adapted to render data received from a master node. Each of the render nodes is further adapted to receive a render command from the master node indicating a portion of the data to be rendered by the corresponding render node. The system also comprises a control application coupled to each of the render nodes and adapted to automatically reallocate the portion of the data rendered by at least one of the render nodes among a remaining portion of the render nodes in response to an event corresponding to the at least one render node.
