Abstract: A processor system comprising a processor and a memory system with a high data transfer rate and low average power consumption of related I/O activity. The processor system may be disposed on a single circuit board. One embodiment of a disclosed system includes a processor system that comprises a processor device, a memory device and a circuit board. The circuit board includes a substrate, electrical contacts, and interconnection lines between the contacts. The electrical contacts of the circuit board may be coupled to electrical contacts on the processor device and the memory device. The interconnection lines communicate signals, such as data or instructions, between the electrical contacts of the memory device and the process device at least 200 billion bits per second while related input/output activity of the processor and the memory consumes an average power less than ten watts.

Abstract: A filter media system, which is capable of operating in the microfiltration regime, offers: low cost, durability, high temperature and chemical resistance, no particulation, mechanical strength, separation efficiency, and biocompatibility. The present invention provides a filter media system comprising a fibrous substrate of at least one of carbon and ceramic fibers, wherein an array of carbon or ceramic fiber whiskers have been grown onto the fibrous substrate, without prior densification of the fibrous substrate. A process for manufacturing a filter media system wherein a carbon fiber is treated with a solution of metal catalyst salt, heated in hydrogen at elevated temperatures to reduce the metal salt to metal, and whisker growth is initiated on the surfaces of the metal deposited carbon fibers by decomposition of low molecular weight hydrocarbon gas at elevated temperature is also provided.

Abstract: A filter media system, which is capable of operating in the microfiltration regime, offers: low cost, durability, high temperature and chemical resistance, no particulation, mechanical strength, separation efficiency, and biocompatibility. A filter media system is comprised of a carbon or ceramic composite substrate which contains a carbon or ceramic matrix reinforced with carbon or ceramic fibers. The composite has an array of carbon or ceramic fiber whiskers grown onto its surface or in its bulk. A process is provided for manufacturing the filter media system wherein a carbon fiber is disposed in a matrix deposited by a CVI or LPI process, at temperatures of about 900 to about 1200° C. to achieve a weight gain of about 10 to 200% (the ceramic matrix is deposited by a CVI process from an aqueous slurry or by use of a preceramic polymer). This composite is treated with an aqueous solution of metal catalyst salt and is then heated in hydrogen at elevated temperatures to reduce the metal salt to metal.
