Abstract: A pyrogenicity test method and assay of endotoxins allows for rapid and ultrahigh sensitivity testing of parenteral pharmaceuticals or medical devices that contact blood or cerebrospinal fluid by employing a Limulus Amoebocyte Lysate (LAL) assay monitored with a photonic-crystal biosensor. The photonic-crystal biosensor is capable of determining the presence of endotoxins in a test sample by detecting shifts in the resonant condition of an open microcavity affected by the changes in the refractive index of the analyte solutions used.

Abstract: An imaging system connected to an occupant monitoring system includes communications with an apparatus for measuring gas or airborne compound concentrations in a vehicle cabin. The apparatus includes a housing configured as a flow tube in fluid communication with ambient air in the vehicle cabin. A spectrometer is mounted within the housing and subject to ambient air flow through the housing, and the spectrometer is connected to a light source and receives reflected light from the air flow to detect by spectrum analysis the concentration of target gases and/or airborne compounds. The spectrometer identifies spectral changes in the light and reflected light within the ambient air flow. The spectrometer communicates with computerized vehicle control systems, and runs software stored to calculate the concentration of target gases and/or airborne compounds from the spectral changes.

Abstract: A radiation imaging apparatus includes an imaging surface; a light source; and an array of micro mirrors that rotate via radiation absorbed in the micro mirrors and reflect light from the light source to generate a distribution of reflected light on the imaging surface. The array first micro mirrors and second micro mirrors. The first micro mirrors have a first structure and the second micro mirrors have a second structure different than the first structure. The second structure is configured to correct for one or more environmental influences on the radiation imaging apparatus. A photodetector captures an image of the distribution of reflected light on the imaging surface. A processor is coupled to the photodetector. A communication interface is coupled with the processor; and a computing device is located separately from the radiation imaging apparatus and in communication with the communication interface.

Abstract: A method, a system, and a non-transitory computer readable medium for accurate Raman spectroscopy. The method may include executing at least one iteration of the steps of: (i) performing, by an optical measurement system, a calibration process that comprises (a) finding a misalignment between a region of interest defined by a spatial filter, and an impinging beam of radiation that is emitted from an illuminated area of a sample, the impinging beam impinges on the spatial filter; and (b) determining a compensating path of propagation of the impinging beam that compensates the misalignment; and (ii) performing a measurement process, while the optical measurement system is configured to provide the compensating path of propagation of the impinging beam, to provide one or more Raman spectra.
