Abstract: Technologies for detecting absorption of electromagnetic radiation traveling through a measurement volume of interest are described herein. In a general embodiment, a laser is used to emit electromagnetic radiation through the measurement volume where absorption is desirably detected. An optical collector receives a portion of the radiation and directs a first fraction of the portion back to a gain medium of the laser, where the radiation is amplified and emitted again, and directs a second fraction to an optical sensor that can detect absorption in the measurement volume based upon attenuation of energy of the radiation. As the radiation feeds back to the gain medium and is emitted again, energy at attenuated wavelengths is amplified less than at other wavelengths. Thus, attenuation of energy of the radiation due to absorption in the measurement volume is cumulative, and relatively small absorptions are amplified, allowing smaller absorptions to be detected more easily.

Abstract: A noninvasive analyzer apparatus and method of use thereof is described for spatially separating light for use in noninvasively determining an analyte concentration of a subject through use of detectors linked to multiple controlled sample illumination zone to sample detection zone distances. The controlled radial separation of illumination and detection zones yields reduced deviation in total observed optical pathlength and/or control of pathlengths in a desired tissue volume for each element of a set of detector elements. Performance using the discrete detection zones is enhanced using a combination of segmented spacers, arcs of detector elements, use of micro-optics, use of optical filters associated with individual detector elements, control of detector response shapes, and/or outlier analysis achievable through use of multiple separate and related observed signals of a detector array.

Abstract: A method is provided for monitoring one or more silicon-containing compounds present in a biogas. The method includes generating a first absorption spectrum based on a ratio of a first spectral measurement and a second spectral measurement. The first spectral measurement is from a non-absorptive gas having substantially no infrared absorptions in a specified wavelength range of interest and the second spectral measurement is from a sample gas comprising the biogas. The method includes generating at least one surrogate absorption spectrum based on, at least, individual absorption spectrum for each of a subset of one or more silicon-containing compounds selected from a larger set of known silicon-containing compounds with known concentrations. A total concentration of the one or more silicon-containing compounds in the biogas can be calculated based on the first absorption spectrum and the at least one surrogate absorption spectrum.

Abstract: This invention relates to a smart IV bag with a structurally integrated optical tag for IV drug identification and monitoring. The optical tag comprises a flow cell with a fluid channel in communication with the IV bag to sample a portion of the IV fluid onto an optical surface embedded in the flow cell. The optical surface causes a light beam to interact with the sampled IV fluid to produce a spectroscopic signal. The spectroscopic signal is then analyzed to obtain the content and concentration information of the IV fluid. Unlike traditional IV bag labels, the optical tag provides real-time, in-situ monitoring of IV fluid content and concentration, which greatly reduces the risk of mislabeling induced IV error.
