Abstract: A video processing apparatus includes a plurality of processing modules, each performing an image processing function, and a central memory interface. The central memory interface accepts read and write memory the said plurality of processing modules and issues burst memory access requests to an external memory by gathering plural memory access requests from the processing modules.

Abstract: Systems and methods for drilling a well bore in a subsea formation from an offshore structure positioned on a water surface with a drill string that is suspended from the structure and includes a bottom hole assembly adapted to form a top hole portion of the well bore. A drilling fluid source on the offshore structure supplies drilling fluid through the drill string to the bottom hole assembly where the drilling fluid exits from the bottom hole assembly during drilling and returns up the well bore. A suction module is disposed at the sea floor and collects the drilling fluid emerging from the well bore. A pump module is disposed on a return line, which is in fluid communication with the suction module, at a position below the water surface and above the sea floor.

Abstract: A printer or other color output device is configured to manage consumable wear. A wear level and a consumable use level of a color cartridge are evaluated. A color cartridge failure mechanism is projected to be either color cartridge wear-out or consumable exhaustion. Where color cartridge wear-out is projected, selection is made between faster printing and a reduced risk of color cartridge wear-out.
