  • Publication number: 20230173153
    Abstract: A measurement apparatus for a peritoneal dialysis apparatus (10) comprises a connecting means (102), which is in contact with a drain line system (104) of the peritoneal dialysis apparatus (10), and electrochemical sensor means (110). The measurement apparatus (100) receives spent dialysate through the drain line system (104) when the dialysis apparatus (10) is connected with a patient (12). The electrochemical sensor means (110), which is in contact with the spent dialysate, outputs an electric signal in response to contents of urea and glucose of the spent dialysate for data processing and/or data presentation of the electric signal.

  • Patent number: 7049595
    Abstract: A method and a measuring system for determining exhaust gas emissions from a moving vehicle by a remote optical measuring technique. The model and/or type of the vehicle under examination is identified, and the driving situation of the vehicle in question is determined at the moment of measurement. A calculatory vehicle model is used to determine a case-specific estimate for the carbon dioxide concentration of the exhaust gas plume depending on the vehicle in question and its driving situation. The accuracy of determining the concentrations of the actual emission gases is improved by eliminating the inaccuracy of the carbon dioxide concentration values.

  • Patent number: 6870619
    Abstract: An entrance slit of the spectrometer is illuminated with optical radiation. An optical component images the entrance slit to an optical modulator by the optical radiation and disperses the optical radiation into a spectrum. The spectrum is modulated by the optical modulator The optical component composes spectral non-dispersive measurement radiation of the spectrum and images the entrance slit included in the measurement radiation to an exit slit which may be the same one as the exit slit or a different one. Measurement radiation is detected from the entrance slit with a detector, which converts the measurement radiation into an electrical measurement signal.

  • Publication number: 20040104345
    Abstract: The invention relates to a method and a measuring system for determining exhaust gas emissions from a moving vehicle (20) by a remote optical measuring technique. According to the invention, the model and/or type of the vehicle (20) under examination is identified, and the driving situation of the vehicle (20) in question is determined at the moment of measurement. A calculatory vehicle model (211, 212) is used to determine a case-specific estimate for the carbon dioxide concentration (CO2) of the exhaust gas plume (40) depending on the vehicle in question and its driving situation. Invention improves the accuracy of determining the concentrations of the actual emission gases (NO, HC, CO) by eliminating the inaccuracy of the carbon dioxide concentration (CO2) values.

  • Patent number: 6717148
    Abstract: The invention relates to a method and an apparatus for measuring a coating from paper or board. The measurement is carried out by one detector at different times or by two detectors simultaneously. IR radiation directed at the coating and radiation emerging from the coating are chopped synchronously in blocks. A wavelength band sensitive and insensitive to the absorption are bandpass filtered and measured in both the MIR and NIR region. The absorption strength is measured in a digital signal processing block by comparing the radiation sensitive to absorption to the radiation insensitive to absorption, and the amount of each coating component is determined in the digital signal processing block on the basis of the absorption strength.
