  • Patent number: 8010289
    Abstract: A lightning detector designed for aircraft carried applications provides for improved lightning discrimination and display. The instrument employs a relatively wide band receiver so as to retain the received waveform or digital replicas thereof. This allows more precise discrimination between desired lightning signals and noise. Signals are processed to provide for effective display of the available information. The display modes that are enabled by the signals include flash and cell mode as well as a combined flash and cell mode. The cell mode provides for generating and displaying a cumulative weight of lightning activity, giving each strike a regional effect as opposed to illustrating it as a point. Color is used to improve the user's grasp of the displayed information; the color illustrating increased intensity from the blue-green to the yellow-red. Flash mode shows locations of the different flashes within the range scale; this mode too may use color for a similar effect.

  • Patent number: 8005617
    Abstract: A lightning detection system and method for detecting a lightning strike are provided. The system includes a lightning detector in a structure susceptible to a lightning strike. The lightning detector includes a data logger configured to log data indicative of a time of occurrence of the lightning strike. The system further includes memory to store data collected from a wide-area lightning detection network. The stored data includes at least one characteristic of the lightning strike. A processor may be configured to process data from the data logger relative to data collected from the wide-area lightning detection network to determine correlated data indicative of a lightning strike affecting the structure. In the event correlated data is determined, the processor may be configured to assign the characteristic of the lightning strike to the structure.

  • Patent number: 7970542
    Abstract: There is discloses a new method for identifying an electromagnetic signal having a known waveform. The method includes using a lightning matched filter receiver having a bank of filters matched to nominal but arbitrary lightning waveforms for detecting lightning. The use of a lightning matched filter receiver facilitates detection of lightning discharges below the noise level. Positioning three or more monitoring stations at different spaced apart geographic locations where each monitoring station has a lightning matched filter receiver where the filters are matched to nominal but arbitrary lightning waveforms can be used to detect and determine the location of a lightning discharge.

  • Patent number: 7957902
    Abstract: A real-time, multi-sensor local-area lightning detection network system. The system uses waveform indicative of electrostatic field changes with respect to time is generated at each of N locations due to a cloud-to-ground lightning strike occurring in the vicinity of the N locations. Each waveform is integrated to generate a corresponding electric field associated with a corresponding one of the locations. A mathematical relationship is used to determine a ground surface location of the lightning strike, height of the lightning strike, and charge per unit length of the lightning strike using each electric field generated during integration of the waveforms.

  • Patent number: 7925442
    Abstract: In order to improve the tie between depositionally equivalent beds relative to two or more basins detected within a multi dimensional seismic volume of interest, pseudo logs based on the average of attributes derived from seismic impedance where the compaction trend is not present are created for each basin. The mean is taken over all available azimuths, following the structural variations of introduced micro layers. The correlation between the pseudo log relative to each basin enable a more reliable interpretation between the different basins from which sound exploration decision can be made. Such a process has been successfully applied to seismic data acquired in deep water environment.

    Abstract: An adaptive relaying control system and method is disclosed for adapting coordination of protective measures provided to an electric-energy distribution system as a function of at least an ambient weather condition. A weather sensor senses the ambient weather condition within a region adjacent to at least a portion of the electric-energy distribution system. A control unit is operatively coupled to the weather sensor to receive a weather signal indicative of the ambient weather condition and determine whether a storm condition exists based at least in part on the weather signal. The control unit establishes a suitable control philosophy for adapting coordination of the protective measures provided to the electric-energy distribution system based at least in part on whether the storm condition exists.
