Abstract: A device for measuring at least one measurand is disclosed which comprises a sensor device with at least one sensor and, via at least one medium-carrying detection path, can be connected to at least one of a plurality of devices outputting at least one flow of a medium to be captured. The at least one sensor is arranged to selectively detect at least one measurand with respect to at least one medium flow output by one of said plurality of devices. A system which includes the sensor device in a centralized way further comprises at least one device outputting the flow of the medium to be measured at least one outlet, wherein one of the devices can be selectively selected and can be connected to the sensor device for a predetermined period of time if several devices outputting a medium flow are connected to the sensor device for measuring at least one measurand.

Abstract: A detecting device for a medium inside a tube portion comprises at least one light source being arranged at a first position relative to the tube portion adapted to be transilluminated with light and being configured to irradiate light onto the tube portion, a detector unit being arranged at a second position relative to the tube portion and being configured to receive light from the at least one light source passed through the tube portion and to analyze a medium inside the tube portion in a spatially resolving manner, and a homogenizing device being arranged at a position between the at least one light source and the tube portion and being configured, for detecting and quantifying differences in brightness due to local differences of the medium inside the tube portion, to create a homogenous and/or isotropic distribution of the light from the at least one light source before the light enters into the tube portion.

Abstract: A method for calibrating a measurement signal and/or for tracking a quantitative variable comprises the measuring of an analyte which exists in a solution with a certain concentration and has predetermined decay kinetics and the generating of a continuous measurement signal having decay kinetics at least corresponding to those of the analyte. The decay kinetics of the measurement signal and the decay kinetics of the analyte are correlated using at least one predetermined calibration point of both decay curves. Subsequent concentration values of the analyte are then calculated from the measurement signal.

Abstract: A material for use in optical amplifiers is described. The material includes an oxide glass substrate material, a rare earth dopant and a silver dopant. The silver dopant enhances photoluminescence of the rare earth dopants in the oxide glass. The silver can be introduced into the glass using an ion exchange process or by ion implantation. Oxide glass doped with erbium ions and silver ions provides a broad excitation band for photoluminescence of Er3+ in the visible and near ultraviolet. An amplifier material according to the present invention can be formed by ion implanting a rare earth ion, for example erbium, and doping with silver by an ion exchange method. Alternatively, the silver can be implanted into the material as well. The resulting silver dopant may be dispersed throughout the oxide glass primarily as ions as a result of the fabrication method.
