Abstract: Technology is provided for an aqueous solution constituent analyzer (100). The analyzer (100) includes an ultraviolet light emitting diode LED (130) with a current source (146) providing variable current thereto. A spectrometer (132) is positioned for receiving light from the LED (130) transmitted through an aqueous solution. A controller (140) receives radiant flux data for a plurality of wavelengths and determines, based on the radiant flux data, a usable number of the plurality of wavelengths that satisfies a relative uncertainty threshold. The controller (140) can increase the current to the LED (130) if the usable number of wavelengths is less than a minimum threshold and calculate a concentration of a constituent of interest in the solution. The controller (140) can also determine a peak wavelength of the plurality of wavelengths having the greatest intensity value, and decrease the current level to the LED (130) if the peak wavelength has an intensity value greater than a saturation value for the spectrometer (132).

Abstract: An apparatus includes a pipe through which a multiphase fluid flows, with a transparent window structure formed in the pipe. A collimated light source emits light through the transparent window structure into the pipe having a wavelength at which a component of a desired phase of the multiphase fluid is absorptive. A photodetector is positioned such that the emitted light passes through the multiphase fluid in the pipe to impinge upon the photodetector. The photodetector has an actual dynamic range for collimated light detection. Processing circuitry is configured to continuously adjust a power of the collimated light source dependent upon an output level of the photodetector so as to cause measurement of the emitted light over an effective dynamic range greater than the actual dynamic range, and determine a property of the multiphase fluid as a function of the power of the collimated light source.

Abstract: The present invention relates to a method for monitoring the filling of a capsule with a medicament, to a corresponding filling method, to the associated apparatuses, and to a computer program for controlling the method and the apparatus. In the monitoring method, after at least part of the capsule has been filled with a predefined filling mass of a predefined closed contour of the medicament, at least the filling mass in the part of the capsule after the filling operation is recorded using digital imaging in a first step, the contour of the filling mass in the part of the capsule is determined from the digital imaging recording in a second step, and the contour is analysed in a third step in order to assess the filling operation in comparison with the predefined contour. The invention provides for external influences on the image properties to be compensated for by controlling the optical system.

Abstract: Disclosed herein is an apparatus including a structure containing a multiphase fluid and having a transparent window. A collimated light source emits light through the transparent window structure at a wavelength at which a component of a desired phase of the multiphase fluid is absorptive. A photodetector is positioned such that the emitted light passes through the multiphase fluid in the structure and out through the transparent window structure to impinge upon the photodetector. The photodetector has an actual dynamic range for light detection. Processing circuitry adjusts a power of the collimated light source in a series of steps dependent upon a relationship between an output level of the photodetector and a threshold to cause measurement of the emitted light over an effective dynamic range greater than the actual dynamic range. Properties of the multiphase fluid are determined as a function of the measured emitted light.
