  • Apparatus and method for measuring viscoelastic properties of mammalian cervical mucous
    Patent number: 4773428
    Abstract: An apparatus and method for measurement of viscoelastic properties of mammalian cervical mucous by generating a bulk acoustic wave which is reflected off of a face in contact with the mucous whereby an output which is a function of the viscoelastic properties is generated based upon at least one characteristic of the reflected bulk wave.
    Type: Grant
    Filed: October 10, 1985
    Date of Patent: September 27, 1988
    Assignees: Hibshman Corporation, Adamtek Corporation
    Inventors: Jacob Y. Wong, Pierre Khuri-Yakub, M. Edward Motamedi, Marcus Y. Wong
  • Rheological testing apparatus and method
    Patent number: 4691714
    Abstract: The device electronically measures fluid viscosity and temperature simultaneously principally for determining the changes in the properties of cervical mucus at the onset of ovulation. Interdigital transducers are used to generate and detect surface and bulk acoustic waves on one side of a slab of fused quartz. The change of phase of surface acoustic waves and the change in amplitude of doubly-reflected bulk acoustic waves are used to detect respectively the temperature and viscosity of fluid sample deposited on the opposite face of the slab.
