摘要: A MEMS based thermoacoustic cryo-cooler for thermal management of cryogenic electronic devices and a resonant tube used therein. A vertical comb-drive can provides an acoustic source through a driving plate to the resonant tube. By exciting a standing wave within the resonant tube, a temperature difference develops across a stack in the tube, thereby enabling heat exchange between heat exchangers. A tapered resonant tube improves the efficiency of the cooling system, compared with a simple cylinder configuration, leading to reduced harmonics and strong standing waves.

摘要: A MEMS based thermoacoustic cryo-cooler for thermal management of cryogenic electronic devices. The cryogenic cooling system can be integrated directly into a cryogenic electronic device. A vertical comb-drive provides an acoustic source through a driving plate to a resonant tube. By exciting a standing wave within the resonant tube, a temperature difference develops across a stack in the tube, thereby enabling heat exchange between heat exchangers. A tapered resonant tube improves the efficiency of the cooling system, compared with a simple cylinder configuration, leading to reduced harmonics and strong standing waves.

摘要: A method and system for processing a graphics frame in a multi-processor computing environment are described. Embodiments of the present invention enable the reduction of the memory footprint required for processing a graphics frame in a multi-processor system. In one embodiment a method of processing a graphics frame using a plurality of processors is presented. The method includes determining a respective assignment of tiles of the graphics frame to each processor of the plurality of processors; allocating a memory area in a local memory of each processor, where the size of the allocated memory area substantially corresponds to the aggregate size of tiles assigned to the respective processor; and storing the tiles of the respective assignment of tiles in the memory area of each respective processor.

摘要: A cylinder block for an internal combustion engine which, in use, supports a rotary crankshaft 40, the block having pairs of opposed lock width surfaces 37 formed thereon for forming an interference fit with respective co-operating lock width surfaces 38 on the crankshaft bearing caps 34 which in use are secured to respective bearing cap support surfaces 36 also formed on the block 31. The lock width surfaces 37, 38 are spaced from the respective bearing cap support surfaces 36 so as to improve stress cracking resistance of the block 31.

摘要: A balance weight has a body having a cavity formed therein, a solid weight member substantially filling the cavity of the body; and an adhesive formed on a side of the body for securing the balance weight to an associated object to be balanced. A balance weight can be secured to a tire and weight assembly and has a solid body formed entirely of plastic material, wherein the body is secured to the tire and wheel assembly via an adhesive layer on one side of the body. The body can have an internal cavity formed within the body and a weight member made of metal which substantially fills the internal cavity.

摘要: A configurable buffer has two storage areas. Depending upon a state of a buffer control signal, the two storage areas are configured to buffer a single stream of data together or to buffer two streams of data separately. In an exemplary video graphics processing application, one stream of data includes pass-through values of fragments being rendered (e.g. color, location, and/or depth values) and the other stream of data includes corresponding displaced (or otherwise perturbed) texture coordinate pairs. Such a buffer may be used to reduce the amount of buffer storage needed to support both single-pass and multipass operations in a pixel pipeline.
