Abstract: To prevent property fires, electrical circuits need to be protected from arc faults due to line-to-line, line-to-neutral and line-to-ground conductivity, known as high current parallel arcing, and protected from arc faults occurring along line-to-line, line-to-load, load-to-load, load-to-neutral and neutral-to-neutral conductor configurations, known as low current series arcing. Devices that protect electrical circuits from these arc faults is known as a combination-type arc fault circuit interrupter (AFCI).

Abstract: A system and method that guides a device to an object using periodically adaptive guidance. The guidance and control system creates a reconstructed line-of-sight (LOS) vector to avoid system destabilization associated with small angle approximation during high bore sight engagements. The guidance system adaptively estimates the periodic maneuver of evasive objects with a set of harmonically balance Kalman filter banks. The Harmonically Balanced Kalman filter banks generate a set of probabilities that weight the effect of each individual Kalman filters on a resultant guidance command signal. The guidance command signal generated by the system acts perpendicular to the object LOS. The guidance and control system uses vectored proportional navigation guidance laws, optimal proportion navigation laws and periodically adaptive augmented guidance laws to generate a guidance command signal to supply to an autopilot.
