  • Ultrasonic detection of porous medium characteristics
    Patent number: 6959602
    Abstract: Plate waves are used to determine the presence of defects within a porous medium, such as a membrane. An acoustic wave can be propagated through a porous medium to create a plate wave within the medium. The plate wave creates fast compression waves and slow compression waves within the medium that relate to the material and structural properties of the medium. The fast compression wave provides information about the total porosity of a medium. While the slow compression wave provides information about the presence of defects in the medium or the types of materials that form the medium.
    Type: Grant
    Filed: March 12, 2003
    Date of Patent: November 1, 2005
    Assignee: Millipore Corporation
    Inventors: Michael L. Peterson, Jr., Anthony DiLeo, Zong Mu Wang, Alan Greenberg
