The present invention features a method for performing an end-to-end data path integrity check in a computer or computer-like system such as a storage router. A predetermined data test pattern is stored in a memory and then transmitted across a data path by a data initiator to a data receiver. The received data test pattern is then retransmitted to the data initiator where it is compared to the original data. Any discrepancies cause an error condition to be declared. The data path may be disabled until the defective component in the data path is isolated and fixed. The method is hardware independent so it may be easily used in an open systems environment where hardware components may be provided by different vendors.

A component which has a surface crevice or crack and contaminants on at least one face of the opening is welded. The weld is effected by first plastically deforming the surface of the component to close the surface opening to a predetermined depth less than the depth of the opening and contaminated faces defining the opening to form a sealed ligament. The sealed ligament leaves unclosed a portion of the crack below the sealed ligament. The closed surface is hermetically sealed by fusion-welding to a depth of penetration equal to or less than the predetermined depth of the sealed ligament to minimize or eliminate expulsion of contaminants in the sealed ligament.

The invention relates to a vehicle body assembly quality online diagnosis method based on component measuring point distance abnormality judgment, which combines the vehicle body assembly process relation and the clamp positioning process information, extracts out-of-tolerance measuring points in measuring data of a tail end detection station, and achieves determination of defective components. The positioning of the faulty station is realized by discriminating the potential faulty stations related to the defective components from top to bottom and judging and analyzing the difference between the actual distance and the standard distance of the measuring points on the defective parts.

According to a preferred aspect of this invention, locations of defects on a semiconductor wafer are found using semiconductor defect inspection instrumentation. Defect composition can also be determined using inspection instrumentation. Wafer defects are represented on a wafer defect map using markings wherein locations of the markings on the map correspond to the locations of the defects on the wafer. The markings also preferably represent a defect type and/or composition. Color-coded dots, for instance, can be used to represent like defect causes or types with like colors. Graphs can be prepared to display defect characteristics using distributions and skews to facilitate quick statistical analysis of the defects. In this manner, wafer defects can be analyzed quickly and efficiently based on characteristics thereof, including, for example, defect type, composition, and cause. This information can be used to help prevent future defects during mass production, thereby improving yield.
