Patents by Inventor David John O'Callaghan

David John O'Callaghan 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: 8769825
    Abstract: A shaving razor that improves stability, corresponding user control and offers a closer shave is provided. The shaving razor can include a razor handle configuration that reduces the propensity for the shaving razor to roll in a users hand and improves the maneuverability of the razor cartridge during shaving. In addition, the shaving razor can include a biasing pivoting member producing a progressively increasing return torque on the razor cartridge that forces the cartridge into flat contact with the skin thus improving glide and shaving closeness.
    Type: Grant
    Filed: October 20, 2010
    Date of Patent: July 8, 2014
    Assignee: The Gillette Company
    Inventors: Daren Mark Howell, David John O'Callaghan, Andrew Martin Whittingham
  • Patent number: 8732955
    Abstract: A shaving razor that offers a closer shave is provided. The shaving razor can include a biasing member producing a progressively increasing return torque on the razor cartridge that forces the cartridge into flat contact with the skin as the cartridge pivots, thus improving glide and shaving closeness. In addition, the shaving razor can include a razor handle configuration that reduces the propensity for the shaving razor to roll in a user's hand and improves the maneuverability of the razor cartridge during shaving.

  • Patent number: 8306753
    Abstract: A system and method for generating a numerical skin model. The skin model may be used to predict the interaction of the skin to various devices, such as shaving devices and absorbent articles, for example. The computer-based numerical skin material model of the simulated skin may comprise a mechanical behavior model of a surface epidermis, a mechanical behavior model of a dermis, a mechanical behavior model of a hypodermis, and a van der Waals hyperelastic formulation to represent the behavior of the simulated skin. A strain stiffening viscoelasticty of the simulated human skin may be determined by a Prony time series expansion.
