    摘要： A method and system for accurately validating performance and functionality of a processor in a timely manner is provided. First, a program is executed on a high level simulator of the processor. Next, a plurality of checkpoints are established. Then, state data at each of the checkpoints is saved. Finally, the program is run on a plurality of low level simulators of the processor in parallel, where each of the low level simulators is started at a corresponding checkpoint with corresponding state data associated with the corresponding checkpoint.

    摘要： This invention relates to a method of fabricating a thermoplastic elastomer which comprises the steps of: (a) fabricating a polyol having a molecular weight of between about 2,000 and about 8,000 and having a level of end group unsaturation of no greater than 0.02 milliequivalents per gram of polyol, said polyol being fabricated in the presence of a double metal cyanide catalyst, (b) reacting said polyol with a diisocyanate to produce an isocyanate-terminated prepolymer, and (c) reacting said isocyanate-terminated prepolymer with a difunctional isocyanato-reactive chain extender in a mold or in an extruder in order to produce an elastomer characterized by a hardness of between a Shore A hardness of about 50 and a Shore D hardness of about 65. Also claimed is the elastomer produced by the above method utilizing a one-shot technique.

    摘要： A microminiature valve having a multilayer integral structure formed on a semiconductor substrate. The valve comprises a semiconductor substrate having inlet and outlet apertures and a raised valve seat. The substrate is overlayed with a nonporous top layer and an intermediate layer. The central portion of the intermediate layer is preferentially etched away to form an enclosed chamber connecting said inlet and outlet ports. The unetched portion of said intermediate layer peripherally supports said top layer above the valve seat. An electrically conductive electrode disposed on the unsupported portion of the top layer permits it to be electrostatically deflected to engage the valve seat and close the valve.
