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).

  • 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.

  • Publication number: 20190015688
    Abstract: An automatic stovetop fire suppressor with sensor triggered activation and method are provided herein. A combination of sensor types is housed within a self-contained fire suppressor, collecting data from the stovetop environment. Sensor types include temperature, light, and infrared. The fire detection method affords expedient fire state determination with discrimination from changes in ambient light, camera flashes, and non-fire heat sources. A bottom lid is secured to a bottom of a can, forming a closed container. A fire suppressing agent is housed within the closed container. From sensed data, the presence of a stovetop fire is assessed. When a fire condition is determined, an electronic match triggers a mechanical shuttle. The fire suppressing agent and battery power are stored in the closed container from manufactured end to activation of the suppressor in a fire condition.
