Patents by Inventor Andrew Vize

Andrew Vize 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).

  • Patent number: 9410878
    Abstract: The Portable Ultrafine Particle Sizer (PUPS) invention is provided. The PUPS is an instrument which can measure particle number concentration for particle sizes under 200 nanometers in-situ. The PUPS is a compact design for quick mounting on vehicles. Size discrimination is accomplished using a compact reverse Differential Mobility Analyzer (rDMA). Particle charging is accomplished using corona ionization. Concentration measurements are completed using a unique flexible printed circuit board electrode which can be removed for cleaning, disposal or chemical analysis of collected particles at the end of its in situ measurement life.
    Type: Grant
    Filed: April 20, 2014
    Date of Patent: August 9, 2016
    Assignee: The University of Vermont and State Agricultural College
    Inventors: Andrew Vize, Matthew Casari, Jeff Frolik, Britt Holmen

  • Publication number: 20120099105
    Abstract: The Portable Ultrafine Particle Sizer (PUPS) invention is provided. The PUPS is an instrument which can measure particle number concentration for particle sizes under 200 nanometers The PUPS has a compact design which allows it to be mounted on vehicles with relative ease. Size discrimination is accomplished using, a compact reverse Differential Mobility Analyzer (rDMA) Particle charging is accomplished using a low-cost method for corona ionization. Concentration measurements are completed using a unique flexible printed circuit board electrode which can be easily removed for cleaning, disposal or chemical analysis of collected particles at the end of its in situ measurement life.
