Abstract: An error checking method and apparatus for appending a variable number of redundancy coding information at the end of each data message or packet transmitted over a multi-stage network for the purpose of protecting the data by using an error detecting code. The amount of additional redundancy coding information implemented is variable and increases with the size of the data message or packet to provide a consistent level of protection.

Abstract: A system provides a tool for computing the most typical fuzzy expected value of a membership function in a fuzzy set. The clustering fuzzy expected value system is used in a question answering system. CFEV is computed by the tool is based on grouping of individual responses, that meet certain criteria, to clusters. Each cluster is considered a "super response" and contributes to the result proportionally to its relative size and the difference in opinion from the mean of the entire sample. In so doing, CFEV represents the opinion of the majority of the population, but it also respects the opinion of the minority. A comparison is made with existed tools such as the FEV and the WFEV and the advantages of CFEV are demonstrated by examples for cases where other methods fail to perform.

Abstract: A computer cooling system provides a more efficient means of cooling, resulting in lower average temperatures and better reliability for the system. It comprises of a rotating baffle or set of baffles, and a formed enclosure. The enclosure accepts cooling fluid in a direction that is parallel to one of its walls. The enclosure is such that a recirculating airflow pattern is set up in its cavity. As the baffle rotates the direction of fluid flow reverses itself in the cavity of the enclosure. The turbulence created by such a system greatly enhances the rate of heat transfer on the components within the enclosure. The exact dimensions of the baffle, and frequency with which it oscillates will depend on the specific system.
