Patent number: 8437973Abstract: 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.Type: GrantFiled: September 15, 2009Date of Patent: May 7, 2013Inventors: John Martin Horan, John Anthony Keane, Gerard David Guthrie, Catherine Ann Hearne

Patent number: 8280669Abstract: 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.Type: GrantFiled: June 6, 2011Date of Patent: October 2, 2012Assignee: Redmere Technology Ltd.Inventors: John Martin Horan, John Anthony Keane, Gerard David Guthrie

Patent number: 7873980Abstract: 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.Type: GrantFiled: June 9, 2010Date of Patent: January 18, 2011Assignee: Redmere Technology Ltd.Inventors: John Martin Horan, Gerard David Guthrie
