One invention aspect forms a mask and matrix of corresponding backups for values in the mask, checks when a mask value is not working, and replaces only that value with only a matching matrix entry. A second matrix of further backups is best formed. Another aspect forms a mask as a matrix of stacks of matching entries for mask positions; selects an entry for each position from the matching matrix stack; and prints using the selected entry at each position. Another aspect forms a mask as a matrix...

Methods and kits for typing prokaryotes and eukaryotes are disclosed. A specific DNA fragment in the rRNA intergene region is amplified by PCR using two universal oligonucleotide primers. The labeled PCR product is cleaved with a variety of restriction endonucleases and electrophoresed on an automated DNA sequencer. The methods and kits are beneficial in, for example, a clinical laboratory because they allow for rapid strain identification of pathogenic bacteria. The DNA fingerprinting methods a...

A semiautomated method and system (30) for swaged coupling process verification are provided. The system nondestructively measures swage groove depth (A) of a swaged coupling (10) for a tube (20). The tube has an inner surface with a first inside diameter at a first distance from a swaged end (22) of the tube and a second inside diameter at a second distance from the swaged end of the tube that is less than the first distance. The swage groove depth is the difference between the first inside dia...
