Abstract: A replacement part validation system is presented that includes a scanning system that scans a received part and provides the scan results of the received part. The system also includes a part recognition module that, based on the received scan results of the received part and provides a part identification and a part quality metric. The system also includes a job assignment module that assigns the received part to an outstanding repair job. The system also includes an output generator that outputs the outstanding repair job and the part quality metric. The system also includes a computing processor that, based on the received scanned results, causes the part recognition module to review a database of parts and retrieve a most-likely match. The part quality metric is based on a comparison of the received part to the most-likely match. The computing processor causes the output generator to output the outstanding repair job and part quality metric to a source.

Abstract: A maintenance-free respirator 10 that includes a mask harness and a mask body 11. The mask body 11 has at least one layer of filter media 56 and has a perimeter 32 that includes an upper segment 34. The upper segment 34 includes first and second concave segments 36, 38 that are located, respectively, on first and second sides of a central plane 40, when viewing the mask body from a top view. A maintenance-free respirator 10 of this configuration is comfortable to wear and can provide a snug fit to a wearer's face, particularly beneath each of the wearer's eyes, while at the same time having an ability to improve compatibility with various protective eyewear.

Abstract: Embodiments of the present disclosure are directed to systems and methods for collection and analysis of environmental air dust (EAD) within an individually ventilated cage rack (IVR) environment for detecting pathogens. The method includes collection of an EAD sample by a collection media, isolation of a plurality of nucleic acids (e.g., RNA and/or DNA) representative of one or more infectious agents from the EAD sample, optional reverse transcription of RNA to cDNA if the isolated nucleic acids contain RNA, amplification of the cDNA and/or DNA (e.g., by polymerase chain reaction (PCR)), and assay interpretation. Optionally, the EAD sample may be analyzed with one or more other sample types (e.g., fecal pellets, oral swabs, body swabs, tissue, etc.) to improve detection of low-copy organisms.
