Howard M Ham Jr, James J Keenan: Electric power supply circuit monitoring systems. Hendry Mechanical Works, Benoit Law Corporation, January 8, 1991: US04983955 (40 worldwide citation)

Monitoring an electric power distribution circuit having a rated load capacity includes continually sensing an intensity of electric power supplied through that circuit. In response to that sensing a first signal indicating when electric power is supplied through that circuit at a predetermined maxi ...

Michael T Parker, Howard M Ham Jr, James J Keenan, Luc P Benoit: Electric arc monitoring systems. Hendry Mechanical Works, Koppel Jacobs Patrick & Heybl, August 3, 2004: US06772077 (13 worldwide citation)

Electric arc monitoring is effected by exploiting the discovery that electric arcs are fractal phenomena in that all essential information that signifies “arc” is contained in each fractal subset. These fractal subsets are logarithmically distributed over the arc spectrum. Monitoring of arcs is most ...
