Abstract: A method for collecting and analyzing urine at the time it is released uses a urine collecting tube joined with a canister. Suction is produced in the collecting tube to join the tube with a penis or to the exterior surface of a female urethra orifice. Once suction is achieved the collecting tube stays in place by suction action. When urine flows into the urine collecting tube a sensor triggers a vacuum pump to produce a higher level of suction to flush the urine into the canister where a level sensor determines the quantity of urine received. Various sensors in the canister determine levels of non-urine partials such as occult blood, drugs, salt, and other substances. When urine is no longer detected within the urine tube, the vacuum pump is turned off and a low-level vacuum remains to assure interconnection with the urine tube.

Abstract: A molten metal inclusion test apparatus includes a spectroscopic appliance for gathering data indicative of the contents of a quantity of molten metal. Laser induced emissions provide spectral data based on the elements present in the melt. Analysis of a series of samplings, or “shots” of laser induced emissions indicates a presence of elements above a background or expected level. These elements appear as spikes in a graphical rendering of the spectral data, defined by a wavelength of the detected element. Correlation of the elements detected in the same shot indicates a composition of the inclusion, typically a particle of an extraneous compound in the melt. Such spectral analysis provides immediate feedback about melt quality, allowing corrective measures to be taken prior to casting.

Abstract: A model-based method of classifying a specimen in a specimen container. The method includes capturing images of the specimen and container at multiple different exposures times, at multiple different spectra having different nominal wavelengths, and at different viewpoints by using multiple cameras. From the captured images, 2D data sets are generated. The 2D data sets are based upon selection of optimally-exposed pixels from the multiple different exposure images to generate optimally-exposed image data for each spectra. Based upon these 2D data sets, various components are classified using a multi-class classifier, such as serum or plasma portion, settled blood portion, gel separator (if present), tube, air, or label. From the classification data and 2D data sets, a 3D model can be generated. Specimen testing apparatus and quality check modules adapted to carry out the method are described, as are other aspects.
