  • Patent number: 9810811
    Abstract: Methods and apparatuses, including computer program products, are described for predicting the potential for severe weather. A computing device receives data associated with lightning activity, where the data includes lightning flash data. The computing device identifies cells of lighting activity based upon the lightning flash data and determines a movement speed, a movement direction, and a lightning rate of the cells of lightning activity based on the received data. The computing device compares the determined lightning rate to a threshold lightning rate, where the threshold rate is set based upon atmospheric conditions in a location of the cells of lightning activity. The computing device determines one or more geographical areas at risk based on the location, the movement speed, and the movement direction of the cells of lightning activity, and issues an alert to remote devices when the lightning rate exceeds a value of the threshold lightning rate.

  • Patent number: 9567847
    Abstract: A method of recording and classifying data collected from an above ground marker for pipeline pig monitoring. Described herein is a method of extracting minimum data attributes from a real-time data sample and packaging same to achieve a significant volume reduction such that the information can be conveyed across communications channels with limited bandwidth. The reduced volume of information can then be utilized at a remote location to reconstruct a close approximation of the original signal with precise timing, and sufficient clarity to allow remote operators to identify pertinent information from the original data sample.

  • Patent number: 9562938
    Abstract: A system and method are proposed to protect critical infrastructure assets from an electromagnetic pulse event. Detonation of a nuclear warhead or geomagnetic storms created by solar corona ejecta or an attack by directed energy weapons can create an electromagnetic pulse event. Several embodiments are disclosed that use radio frequency (RF) sensors, electrostatic discharge sensors and geomagnetic sensors that feed sensor signals to an event characterization and detection unit that analyzes and predicts early occurrence of an electromagnetic pulse event. Critical sensor signals are recorded for future use and are used to refine autonomic algorithms used to predict future electromagnetic pulse events from the sensor data.
