  • Publication number: 20180312930
    Abstract: A method for analyzing a liquid sample, such as wine, in order to detect the possible presence of sulphite-resistant yeasts of the Brettanomyces bruxellensis species. The method includes detecting whether yeasts of the Brettanomyces bruxellensis species belonging to the genetic group of triploid oenological yeasts are found in the sample. If such yeasts are detected, then the sample is deduced to contain sulphite-resistant yeasts of the Brettanomyces bruxellensis species.

  • Publication number: 20180149592
    Abstract: The present disclosure provides a portable device for controlling an alcoholic beverage that includes a single light source emitting a monochromatic excitation light beam of a wavelength between 350 and 650 nanometers, a beam splitter to reflect the light beam, a focus and collection lens, and a positioning device to orient the light beam along a direction substantially normal to an outer surface of the container. The positioning device positions the outer surface of the container at a predetermined distance from the focus lens. The device includes a filtering device for filtering fluorescence radiation captured by the focus lens to eliminate wavelengths shorter than or equal to the wavelength of the light beam. A spectrometer module produces a signal corresponding to the measured spectrum of the fluorescence radiation and an analysis module compares the measured spectrum to a reference spectrum.

  • Patent number: 9952060
    Abstract: A method for the real-time estimation of the total consumption of a fluid, in particular water or gas, distributed from a unit (A) to users (b1, b2 . . . ) via a network of supply pipes (E) with a branch (d1, d2 . . . ), for each user, fitted with a counter (c1, c2 . . . ) of the fluid consumed by the user, which method involves defining cohorts of users having homogeneous behavior with regard to the consumption of fluid; defining, for at least one of these cohorts, a sample of users from the cohort that is statistically sufficient to represent the cohort; fitting only the branches of the users of each sample with a remote reading device (t1, t2, . . . ) for reading the consumption; also fitting remote reading devices to the branches of the users of the other cohorts that have not been sampled; and processing the information provided by the remote reading devices to obtain a real-time value representative of the total consumption of the network.
