Abstract: A system for detecting gas leaks and determining their location and size. A data gathering portion of the system utilizes a hub and spoke configuration to collect path-integrated spectroscopic data over multiple open paths around an area. A processing portion of the system applies a high-resolution transport model together with meteorological data of the area to generate an influence function of possible leak locations on gas detector measurement paths, and applies an inversion model to the influence function and the spectroscopic data to generate gas source size and location.

Abstract: Determining optical visibility in an environment that may contain airborne dust particles is described. In one aspect, a method determines an ambient relative humidity in the environment. A near infrared wave is transmitted through a portion of the environment. An optical visibility in the environment is calculated based on the ambient relative humidity and attenuation of the near infrared wave during transmission through the environment. Various contrast thresholds are employed in the determination of optical visibility in the environment.

Abstract: Optical systems are provided. One such optical system includes an optical source that propagates a source beam of light. A diffracting component is optically coupled to the optical source and is operative to receive the source beam and produce a diffracted beam. A target is located to receive the diffracted beam. Additionally, a compensating system repositions at least one of the optical source, the diffracting component, and the target in response to a detected change in refractive index of a medium through which the diffracted beam propagates so that the diffracted beam continues to be received by the target. Methods and other systems also are provided.

Abstract: A method of and an apparatus for determining the individual existence of first and second groups of particles contained in a fluid and differing in characteristics from each other that are capable of, e.g., during an automatized ion exchange operation, individually distinguishing anionic and cationic ion-exchange resin particles and capable of easily monitoring their regeneration state. A plurality of beams comprising different wavelength bands are emitted from light-emitting elements, projected onto a subject of measurement containing first and second particles, and received by light-receiving elements, and the reflectivities of the beams are measured. When the ratio of the reflectivity of a first of the beams to that of a second of the beams is above a predetermined value, the subject of measurement is determined to contain particles of the first kind, whereas when that ratio in reflectivity is below the predetermined value, the subject of measurement is determined to contain particles of the second kind.

Abstract: A reaction carrier (14), a measuring device (12) and a measuring method measure a concentration of gaseous and/or aerosol components of a gas mixture. A flow channel (42), extends between two connecting elements (44) and defines a reaction chamber (46) with an optically detectable reaction material (48) that reacts a component of the gas mixture or with a reaction product of the component. The reaction carrier (14) includes a temperature-measuring element (88). The measuring device (12) includes a temperature-measuring element (90) which records a temperature of the measuring device (12) and/or of the reaction carrier (14), and a temperature-determining unit (92) which determines the temperature of the gas mixture as a function of the measurement result of the at least one temperature-measuring element (90). The measuring method includes determining a concentration of the component on the basis of an optically detectable reaction and the determined temperature of the gas mixture.
