Patent number: 9759837Abstract: This invention relates to a data communication system/method for use in a downhole application wherein electrical energy is supplied over a multiple-conductor power cable to a motor assembly of a downhole tool such as an electric submersible pump. A power leg coupling interfaces a surface controller of a downhole instrument to the conductors of the tool's power cable. Uplink communication of telemetry data occurs via current modulation generated by the downhole instrument and interpreted by a surface controller. Downlink communication of downhole instrument data occurs over a different communication scheme supported by the downhole and surface controllers. Downlink communication scheme provides a supply of power to the downhole instrument. Protection of downhole electronics and continuity of communication is ensured in the event of a ground fault on the power cable. Both downlink and uplink communication frequencies are adaptive based on frequencies and voltages present on the power cable.Type: GrantFiled: November 11, 2014Date of Patent: September 12, 2017Assignee: SERCEL-GRC CORPORATIONInventors: Guillaume Grente, Anthony Thornberry, David Funkhouser, Bryon Western

Patent number: 9615452Abstract: A power substrate utilizing silver conductors on ceramic, and the process for making said device. The insulating portion of the substrate is fabricated from a ceramic by placing trenches into the ceramic which can be filled with silver conductors. These conductors can serve the purpose of traces for electrical interconnection, pads for die attachment, as well as thermal conductors for heat pipes and heat spreaders. The conductors can be made on both the top and the bottom of the ceramic. Such substrates may be used for a multitude of applications requiring power substrates for conducting large currents, and are suitable for high efficiency, high temperature, and/or high reliability applications.Type: GrantFiled: May 10, 2013Date of Patent: April 4, 2017Assignee: CREE FAYETTEVILLE, INC.Inventors: Bryon Western, John Fraley

Patent number: 9435819Abstract: A turbine environment wireless transmitter for monitoring bearing health inside jet turbines. This transmitter has the ability to operate in 225 to 300 degree Celsius environments and monitor real time bearing temperature and vibration and transmit that data to a centralized system for processing. The system is powered by a built in thermal electric generator, which produces power in response to a thermal gradient across it. The information transmitted is used to monitor and diagnose a bearing operating parameters in real-time and predict a failure event before any damage occurs.Type: GrantFiled: April 29, 2013Date of Patent: September 6, 2016Assignee: Cree Fayetteville, Inc.Inventors: John Fraley, Bryon Western, Roberto Marcelo Schupbach
