Jacques Delage has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Luminescence measuring device with pre-filter effect suppression
    Patent number: 7180589
    Abstract: A device for measuring the intensity of a luminescence radiation emitted by at least one chemical species probed, along a trajectory by an excitation radiation. The device includes n measurement channels, where n is an integer greater than or equal to 2, each measurement channel being used to measure a fraction of the intensity of the luminescence radiation emitted along the trajectory. The device is also applicable to analytical chemistry to make speciation measurements.
    Type: Grant
    Filed: April 25, 2002
    Date of Patent: February 20, 2007
    Assignee: Commissariat a l'Energie Atomique
    Inventors: Laurent Couston, Jacques Delage
  • Device for inline measurement laser pulses and measuring method by photoacoustic spectroscopy
    Patent number: 6937340
    Abstract: A piezoelectric sensor (7) is dedicated to making a precise measurement of the light amplitude of pulses (2) from a laser (1), so that quantitative measurements such as photo-acoustic spectroscopy can be used to precisely measure the concentration of some bodies in a solution.
