Patents by Inventor Richard Roller

Richard Roller 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).

  • Novel antiviral acitivities of primate theta defensins and mammalian cathelicidins
    Publication number: 20040086535
    Abstract: The present invention relates to the use of anti-viral peptides in the inhibition and treatment of viral infections, in particular infections caused by enveloped viruses. These anti-viral peptides, some natural and others artificial, adopt either amphiphilic alpha-helical or a theta structure where the homodimeric or heterodirner peptides are joined by both cysteine bonds and circularization of the peptides. These agents may be used alone or in combination with more traditional anti-viral pharmaceuticals.
    Type: Application
    Filed: November 25, 2003
    Publication date: May 6, 2004
    Applicant: The University of Iowa Research Foundation
    Inventors: Wendy Maury, Jack Stapleton, Richard Roller, Mark Stinski, Paul B. McCray, Brian Tack
  • Reactive energy absorbing system
    Patent number: 6575497
    Abstract: An energy absorbing device for a steering column includes first and second elongated plastically deformable straps connected to the steering column. A bushing connected to stationary vehicle support structure is engagable with the straps in a manner such that when the steering column collapses the straps advance linearly across the bushing and thereby resist collapse of the steering column. One of the straps may be disconnected from the steering column at the instant of a crash event, in circumstances where less resistance to steering column collapse is desired.
    Type: Grant

    Assignee: Delphi Technologies, Inc.
    Inventors: Philip J. McCarthy, Neal Richard Roller, Xiaoyu Li
