Patents by Inventor Dave Hardell

Dave Hardell 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: 8067701
    Abstract: An apparatus providing one or more I/O connections to a computer. The apparatus includes a Faraday cage generally about a flex cable, or other computing element, that may translate when the I/O ports to the computer are utilized. The embodiment maintains the Faraday cage for the flex cable or element as the I/O port housing opens or closes.
    Type: Grant

    Date of Patent: November 29, 2011
    Assignee: Apple Inc.

  • Patent number: 7963809
    Abstract: A small form-factor, high performance connector is disclosed. This connector is intended for use with high bandwidth digital video, implementing differential digital signaling, as well as for high bandwidth analog video. The described connector system performs the function of the Digital Visual Interface (DVI) connector, but in a significantly smaller package. Signal integrity is maintained in the smaller form factor by the expedient assignment of signals to pins so that the pin above or below any signal is not used on that interface, thus reducing the chances for signal crosstalk. The pin shape and spacing are created to match pin lengths and minimize inductance while maintaining the proper impedance up to 2.5 GHz. This connector system also implements a tactile feedback mechanism to aid with cable plug insertion, and incorporates a keying mechanism to prevent reverse-plugging.
