Patents by Inventor John D. Wanjura

John D. Wanjura 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).

  • Lint cleaning system for cotton processing
    Patent number: 9903052
    Abstract: The lint cleaning system is a modified jet-type lint cleaner that includes a supplemental air control vane. The supplemental air control vane (among other things) segregates discharged foreign materials from incoming supplemental air so that the incoming supplemental air is not contaminated by the discharged materials. The current system also enables a user to more effectively control the volume and the pathway of supplemental air entering the cleaner and thereby optimize the function of the air cleaner.
    Type: Grant
    Filed: April 17, 2015
    Date of Patent: February 27, 2018
    Assignees: The United States of America, as represented by The Secretary of Agriculture, Bayer Cropscience LP
    Inventors: John D. Wanjura, Craig Bednarz, Gregory A. Holt, Mathew G. Pelletier

  • Interrogation measurement system and method providing accurate permittivity measurements via ultra-wideband removal of spurious reflectors
    Patent number: 8742768
    Abstract: A method and apparatus for determining at least one property of a target material is disclosed. The method is constituted of: providing a time varying signal at comprising frequency content over a range of frequencies; transducing the provided signal so as to interact with the target material; receiving the provided time varying signal after interaction with the target material; mixing the received time varying signal with a portion of the provided time varying signal; determining the propagation delay associated with the target material of the received provided time varying signal at each of a plurality of frequencies within the range of frequencies; and determining at least one property of the target material responsive to the determined propagation delay at each of the plurality of frequencies.
