摘要： A sensing system and method is provided for crop material in a harvester. The sensing system includes a conveyor auger device oriented in a substantially vertical direction and having an entrance aperture, an exit aperture located upwardly above a radially oriented sensing aperture disposed therebetween. The conveyor auger device includes a conveyor auger having a flight for moving crop material upwardly, wherein the flight has a reduced radial extension adjacent the sensing aperture. A sensor disposed at or adjacent the sensing aperture senses the essentially continuously upwardly moving crop material for determining a property thereof.

摘要： A method of making passive microscopic Fabry-Pérot Interferometer (FPI) sensor includes forming a three-dimensional microscopic optical structure on a cleaved tip of an optical fiber that reflects a light signal back through the optical fiber. The reflected light is altered by refractive index changes in the three-dimensional structure that is subject to at least one of: (i) thermal radiation; and (ii) volatile organic compounds.

摘要： A flow path plate for analysis of a component in a liquid sample, flowing within the flow path plate, by irradiating the liquid sample with measurement light is provided. The flow path plate includes a plate body having transparency; a flow path formed within the plate body and through which the liquid sample passes; a chamber provided in a part of the flow path and formed by a space having a cross-sectional area greater than cross-sectional areas of other parts of the flow path; and an internal part for detection disposed in the chamber and having a through hole. The through hole has an inner wall surface and constitutes a part of the flow path. The measurement light passes through the through hole. The internal part is configured to inhibit transmission of the measurement light from the inner wall surface of the through hole to the outside.

摘要： A method and a device monitors the quality of gaseous media dispensed by a filling station, in particular hydrogen, by an infrared measuring system. The infrared measuring system is connected into the dispensing path of the respective gaseous medium extending from the filling station to a consumer, and measures the transmission of infrared radiation at different wavelengths and different pressures. From the transmission measurements, the concentration of contaminants, which influence the quality, is calculated. At least when predetrminable quality parameters are exceeded, this exceeding is indicated.

摘要： A method and apparatus for monitoring deposit formation in a process having an aqueous flow is provided. According to exemplary embodiments, a feed flow of an aqueous liquid is provided onto a receiving surface to be monitored. At least part of a receiving surface is illuminated with at least one light source. Visual data is collected across the receiving surface and analyzed. The quality and type of deposition attached to the receiving surface is classified based on information obtained from the analyzed visual data, and a quantitative scaling and/or fouling indication is computed based on the classification.
