Patents by Inventor Jim Marshall

Jim Marshall 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).

  • Multi-mode optical navigation
    Patent number: 8253688
    Abstract: A system and method is provided for selecting a light source in a pointing device such as a mouse. The selection of the light source may be based on attributes of a received image, which are in turn based on reflected light received at the pointing device from the tracking surface. Because the attributes of the receive image are related to characteristics of the tracking surface over which the pointing device is moved, an illumination source appropriate for a particular surface type can be chosen.
    Type: Grant
    Filed: July 6, 2010
    Date of Patent: August 28, 2012
    Assignee: Microsoft Corporation
    Inventors: David Bohn, Krishna Darbha, Jim Marshall, Brian L. Hastings
  • Carbon nanotube-based electronic devices
    Patent number: 8013247
    Abstract: Carbon nanotube-based devices that can be used to meet the growing miniaturization and performance needs of electronic systems, are provided. In particular, a transmission line and inductor that include nanotube bundles is disclosed. In a further embodiment a method for isolating nanotubes with proteins is disclosed. In another embodiment a nanoswitch using nanotubes is disclosed. In a final embodiment a low loss, high permeability material is disclosed that includes a conductive coil and a set of nanotube toroids.
    Type: Grant
