摘要:
A memory manager interfaces between a rendering application and the driver controlling one or more memories. A multi-level brick cache system caches bricks in a memory hierarchy to accelerate the rendering. One example memory hierarchy may include system memory, AGP memory, and graphics memory. The memory manager allows control of brick overwriting based on current or past rendering. Since different memories are typically available, one or more memory managers may control storage of bricks into different memories to optimize rendering. Management of different memory levels, overwriting based on current or previous rendering, and an interfacing memory manager may each be used alone or in any possible combination.

A method for rendering a two-dimensional image comprising: (a) obtaining a first three-dimensional set of data for a relatively high quality image; (b) generating a second three-dimensional set of data for a relatively low quality image from the obtained three-dimensional set of data; (c) rendering a relatively low quality two-dimensional image from second three-dimensional set of data; (d) rendering a first portion of a relatively high quality two-dimensional image from a first portion of the first three-dimensional set of data; (e) blending the rendered low quality two-dimensional image with relatively high quality two-dimensional image; (f) rendering a second portion of a relatively high quality two-dimensional image from a different portion of the first three-dimensional set of data; and (g) blending the rendered low quality two-dimensional image from second three-dimensional set of data with relatively high quality two-dimensional image from the second portion of the first three-dimensional set of data. The process repeats until the entire image is rendered.

A method and system for monitoring an exhaust gas adsorber includes a comparison module comparing the first exhaust gas constituent signal corresponding to an amount of exhaust gas constituent in an exhaust conduit and a second exhaust gas constituent signal corresponding to an amount of exhaust gas constituent in the exhaust gas adsorber. The system includes a fault module generating a fault in response to comparing in the comparison module.

Operation of a spark ignition, direct injection engine having an aftertreatment system including an oxidation catalyst and a selective catalyst reduction device is described. The method includes controlling to a stoichiometric air/fuel ratio and retarding spark ignition timing. Engine fueling is then controlled to a lean air/fuel ratio and spark is retarded. The engine is then operated to generate ammonia reductant. Engine operation then comprises operating at a preferred air/fuel ratio and controlling spark ignition timing to a preferred timing.

The invention provides environment aware messages delivery systems, apparatus and methods. In example embodiments the system and method automatically deliver messages to the user based on the environment around the user. In the system and method, a portable message redirection agent cooperates with a message delivery service manager in the environment to discover available message delivery service, and sets message forwarding options without the user's operation. The system and method of the invention can make full use of the existing message redirection mechanisms in more flexible manner.

An engine has a crankshaft. A compression piston within a compression cylinder is connected to the crankshaft such that the compression piston reciprocates through an intake stroke and a compression stroke. An expansion piston within an expansion cylinder is connected to the crankshaft such that the expansion piston reciprocates through an expansion stroke and an exhaust stroke. A crossover passage interconnects the compression and expansion cylinders. The crossover passage includes a crossover compression valve and a crossover expansion valve. A runner section is in a downstream portion of the crossover passage, and a helical end section is integrally connected to the runner section. The helical end section has a funnel spiraling about a valve stem of the crossover expansion valve. The funnel forces incoming air to rotate about the valve stem prior to entering the expansion cylinder to promote turbulent kinetic energy in the cylinder air/fuel charge.

A housing (10) with three-dimension appearance includes a transparent substrate (11), a micro lens array (12) formed on one surface of the transparent substrate, and a decorative layer (13) formed on another surface of the transparent substrate at an opposite side to the micro lens array. A method for making the housing is also provided.
摘要:
A heat dissipation device includes a substrate, a fin assembly located on the substrate, a plurality of heat pipes connecting the substrate and the fin assembly, and a fan fixed on the substrate by a securing device. The securing device includes a holder fixed to the substrate and a plurality of elastic fasteners. The fasteners secure the fan onto the holder and each includes a sandwiched portion sandwiched between the fan and the holder to segregate the fan from the holder.
