Patents by Inventor Warren B Johnson

Warren B Johnson 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).

  • Universal monitor and fault detector in fielded generators and method
    Patent number: 10608564
    Abstract: A method and system for monitoring an engine driven generator system (GMS) is provided herein. The system self-configures across generator types and manufacturers via a learning algorithm. Additional sensors are included in the system to provide a robust set of sensor data. Data analysis employed includes comparison to threshold levels, trending of historical data, and Wavelet analysis. A graphical touch screen is provided to users for both controlling the GMS and for viewing results. Monitoring results include operating conditions, existing faults, and warnings of undesirable conditions. Ethernet connections afford review of real time data, diagnostic feedback, and prognostic information at a central location. A sleep state of the GMS conserves generator battery life.
    Type: Grant
