Filed: 2003-10-24
Granted: 2012-05-22
Abstract: A method for the differentiation of inflammatory bowel disease (IBD) FROM IRRITABLE BOWEL DISEASE (IBS) followed by distinguishing ulcerative colitis and Crohn0s disease from other gastrointertinal illnesses. This highly differential method first uses the presence of elevated lactoferrin as a marker of intestinal inflammation to differentiate IBD from IBS. Patents suspected of IBD are then analyzed for fecal anti-Saccharomyces cerevisiae antibodies (ASCA) AS AN INDICATOR OF Crohn~s disease and fecal anti-neutrophil cytoplasmic antibodies (ANCA) as an indicator of ulcerative colitis. IBD patients are further monitored for intestinal inflammation using fecal lactoferrin to evaluate the effectiveness of medical therapy and to predict relapse. The apparatus comprises either a qualitative enzyme-linked immunoassay or other immunoassay that utilizes antibodies specific to human immunoglobins for the measurement of total endogenous lactoferrin, ASCA and ANCA in human feces. The method and apparatus can be used by healthcare providers to identify IBD and distinguish ulcerative colitis from Crohn~s disease.

Title: Ownership reassignment in a shared-nothing database system
Inventor: BAMFORD ROGER J
IPC: G06F17/30
Filed: 2004-07-28
Granted: 2011-05-03
Abstract: Various thechniques are described for improving the performance of a shared-nothing database system in which at least two of the nodes that are running the shared-nothing database system have shared access to a disk. Specifically, techniques are provided for changing the ownership of data in a shared-nothing database without changing the location of the data on persistent storage.  Because the persistent storage location for the data is not changed during a transfer of ownership of the data, ownership can be transferred more freely and with less of a performance penalty than would otherwise be incurred by a physical relocation of the data. Various techniques are also described for providing fast run-time reassignment of ownership. Because the reassignment can be performed during run-time, the shared-nothing system does not have to be taken offline to perform reassignment. Further, the techniques describe how the reassignment can be performed with relatively fine granularity, avoiding the need to perform bulk reassignment of large amounts of data across all nodes merely to reassign ownership of a few data items on one of the nodes.

Abstract: A folding hand tool with an open-assist mechanism that is not mechanically linked to a folding knife blade is disclosed. The open-assist mechanism is allowed to rotate around the same pivot used by the blade, and includes a lug that interacts with the kick of the blade when rotated. Because the open-assist mechanism is not mechanically linked to the blade, it has a range of free motion that promotes safety, and allows the mechanism to rotate into the blade cavity when the blade is extended. The folding knife also may have a carabiner that shares the blade cavity with the blade, with the blade nesting into the carabiner to save space, thereby giving the folding knife a smaller profile.
