Patents by Inventor Gerard David Guthrie

Gerard David Guthrie 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: 8437973
    Abstract: A self calibrating cable, including a USB3 cable, with a boost device of the embodiment of the invention is described, in which parameters that control the response of the boost device are set optimally in a self-calibrating process comprising looping the boosted cable on itself through a calibration fixture that contains a calibration control device. The boost device includes pattern generators and a sampling circuit. Each high speed channel of the cable is separately tested and calibrated with the help of one of the other channels serving as a sampling channel. Additional embodiments provide for a selected replica boost device and a distinct pattern generator device in the calibration fixture. A corresponding system and method for calibrating a cable are also provided.

  • Patent number: 8280669
    Abstract: An HDMI cable may exhibit frequency dependent signal attenuation, inter symbol interference, and inter-pair skew. A boost device integrated with the cable can compensate for such impairments of the cable. A self calibrating cable with a boost device of the embodiment of the invention is described, in which parameters that control the response of the boost device are set optimally in a self-calibrating process including looping the boosted cable on itself through a calibration fixture that contains a calibration control device. The boost device includes pattern generators and a sampling circuit. Each high speed channel of the cable is separately tested and calibrated with the help of one of the other channels serving as a sampling channel.

  • Patent number: 7873980
    Abstract: A High Definition Multimedia Interface (HDMI) cable carries high speed encoded data which are transmitted differentially over data channels, along with a clock. A Mobile High-Definition Link (MHL) cable carries high speed data which are multiplexed to achieve smaller connectors with fewer pins. A MHL-to-HDMI cable is proposed which includes an embedded MHL to HDMI format conversion device for demultiplexing the received MHL-formatted signal and outputting an HDMI-formatted signal. The embedded device is powered by a combination of power sources, the power being harvested from the high-speed HDMI signals themselves.
