Patents by Inventor Sylvain Dominique Masset

Sylvain Dominique Masset 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).

  • Publication number: 20170343461
    Abstract: A preferred form of the invention is directed to a system and method used to test filters. The system preferably includes a base unit and a probe operably associated with the base unit. The probe is configured to be deployed adjacent the filter being tested while the filter is located in an operating position. The probe is further configured to allow an operator to vary the mode of operation of the base unit from the probe. The system is configured to automatically exhaust any residual test sample from the base unit and the probe when the system changes between testing a sample upstream and downstream of the filter. The system further includes noise suppression on at least one of the upstream test sample and downstream test sample. The system further is configured to detect when the probe is connected to the base unit.

  • Patent number: 7694548
    Abstract: The preferred form of the present invention is directed to systems and methods used to test objects including but not limited to filters, respirator cartridges and filter media. The object to be tested is subjected to an aerosol challenge while the penetration percentage and resistance at a given flow are monitored to ensure that the object will function as desired. Preferably, the test object is challenged with a salt aerosol. However, any suitable aerosol may be used. A replenishment member is provided for automatically and continuously replenishing the reservoir of an aerosol generator. The replenishment member is configured such that there is no need for an operator to monitor the liquid level in the aerosol generator reservoir either during replenishment or at anytime while the apparatus is operated. The replenishment member of the preferred form of the present invention does not require interruption of the filter testing process to replenish the aerosol generator reservoir.

  • Patent number: 7224454
    Abstract: An analyzing probe for insertion into numerous different environments to determine at least one characteristic of particulate matter suspended in a fluid stream of a test sample. Preferably, the analyzing probe includes a minimal amount of optical elements such as lenses that are subjected to the conditions of the environment of the fluid stream to be tested. Further, the analyzing probe is preferably designed so that it can be readily manufactured, operated and installed by relatively unskilled laborers.
