Abstract:
A vehicle configured for conveying at least one container. The vehicle has a supporting portion configured for holding said container, and a primary lifting mechanism for controlling elevation of the supporting portion. The lifting mechanism is configured to move the supporting portion between an elevated position and a lowered position. The supporting portion is configured for assuming a retracted state associated with a first outline of the vehicle when seen from above, and combinable at least with the lowered position of the supporting portion, and an extended state associated with a second outline of the vehicle when seen from above and combinable at least with the elevated position of the supporting portion. The supporting portion in its extended state has projecting areas, projecting in the second outline relative to the first outline and configured for supporting said container.

Abstract:
A portable, tabletop fluid sampling device simplifies spectral analysis to produce an accurate but inexpensive chromatic fingerprint for fluid samples. In one embodiment, the sampling device uses an array of variable wavelength LED emitters and photodiode detectors to measure Rayleigh scattering of electromagnetic energy from the fluid sample contained in a cuvette. Either the fluid itself, or particles suspended in the fluid can then be identified by performing spectral pattern matching to compare results of a spectral scan against a library of known spectra. A wide range of applications include substance identification, security screening, authentication, quality control, and medical diagnostics.
Abstract:
Method and apparatus for external cavity laser absorption spectroscopy There is disclosed an apparatus, and corresponding methods, for determining one or more characteristics of a sample in an absorption cell using laser absorption spectroscopy. For example, the characteristic may be concentration of a species in the sample. The apparatus comprises an external cavity semiconductor laser comprising a semiconductor gain medium within an optical resonator. The absorption cell is located within the optical resonator of the external cavity semiconductor laser so as to be optically coupled with the gain medium. A controller is arranged to provide a varied injection current to the semiconductor gain medium. A photodetector is arranged to detect laser light output by the external cavity semiconductor laser. An analyser is arranged to determine one or more characteristics of the sample from behaviour of the detected laser light output as a function of the varied injection current.
Abstract:
Thermally controlled enclosures that can be used with gas analyzers are described. The enclosures incorporate one or more phase changing materials that buffer ambient and internal heat loads to reduce the power consumption demand of mechanical or electronic heating apparatus. Maintenance of gas analyzer equipment at a consistent temperature can be important to achieving stable and reproducible results. Related systems, apparatus, methods, and/or articles are also described.
