Abstract: A process for monitoring and controlling a slave analyzer and a manufacturing unit linked to the slave analyzer, including the steps of a) feeding standard samples having a known characteristic to a master analyzer; b) generating master signals from the master analyzer based on the known characteristic of the standard samples; c) feeding the standard samples to the slave analyzer; d) generating slave signals from the slave analyzer based on the known characteristic of said standard samples; e) generating a transfer algorithm relating the slave signals to the master signals, the transfer algorithm being defined by parameters; f) periodically repeating steps c) through e); g) monitoring over time an indicator selected from the group consisting of one of the parameters and a function of at least two of the parameters; h) identifying a cause of alteration of the indicator based on a cause/effect diagram; and i) checking the slave analyzer and the manufacturing unit based on the cause of alteration of the indicato

Abstract: A method for correcting a signal delivered by a slave measuring instrument with respect to a reference signal delivered by a master measuring instrument of the same type involved in the analyzing of the same product includes the provision of standardization signals delivered by both the slave instrument and the master instrument as they analyze calibration products, each calibration product having a particular known calibration characteristic. These standardization signals are subjected to series decomposition so that they are simplified prior to their being formed into a correction coefficient matrix useful in correcting a signal derived from a slave measuring instrument performing an actual analysis of the characteristic of a test product like the calibration products. When a test product undergoes analysis, it is analyzed by the slave measuring instrument to determine a signal which is then subject to a further series decomposition and correction with the aid of the stored correction matrix.

Abstract: Between the high electronic conduction structures of the multilayer assembly an electric voltage signal is applied of which at least one portion includes an alternating component which has an amplitude between 0.05 and 100 volts and a frequency lower than 5 kHz and preferably between 2 and 2000 Hz so as to generate within the multilayer assembly an alternating ion current susceptible of producing a heating of the ion conducting macromolecular material by Joule effect. Application to the heating of electrochemical current generators in thin layers with solid polymer electrolyte or to the surface heating of elements of various regular or irregular shapes of which the surface is coated with the multilayer assembly.

Abstract: The optical system, which is comprised of a thin layer of ion conducting, macromolecular material, or solid polymer electrolyte sandwiched between two electrodes presenting each a conducting deposition carried by a support plate such that at least one of the conductor depositions and the associated support plate are transparent, is heated by applying between the conductor depositions of said electrodes an electric voltage signal of which at least one portion includes an alternating component which has an amplitude between 0.05 and 100 volts and a frequency lower than 5 kHz and preferably between 2 and 2000 Hz so as to generate within said optical system an alternating ionic current susceptible of producing a heating of the ion conducting macromolecular material by Joule effect. The optical system to be heated, which may be an electrochromium device, may have particularly a glazing type structure or a mirror type structure.

Abstract: Electrochemical generator, the electrolyte of which is made of a macromolecular material comprising a salt in solution and of which the positive electrode is a composite electrode which comprises as active material a metallic compound adapted to be reduced by the cation of the salt in solution by generating during this reduction new species which can include the zero oxidation degree metal, said generator being able to operate reversibly at ambient temperature.
