  • Patent number: 8237459
    Abstract: A fall of potential method of determining earth ground resistance which utilizes an earth ground tester and eliminates the need for utilizing removable ground stakes. Rather than utilizing a “far stake” the method provides connection of the earth ground tester to the telephone wires. Rather than utilizing a “near stake” the method provides for connection of the earth ground tester to the cable shield.
    Type: Grant

  • Publication number: 20090102490
    Abstract: The present invention provides a circuit for performing a stress test on a paired line. The circuit provides for first and second balanced outlet pathways for applying an AC signals to the paired line. Although each of these first and second balanced outlet pathways include balanced capacitors, the need to vet these capacitors in order to achieve proper operation of the circuit is eliminated.

  • Patent number: 6608900
    Abstract: A load management system for monitoring the output from a power supply and managing the load on said power supply, said load management system comprising a hysteresis circuit for signaling a load element to stop drawing current when an output voltage at said output falls below a first threshold and for signaling said load element to resume drawing current when said output voltage rises above a second threshold, said hysteresis circuit comprising a first state sensing circuit having an input coupled to said output and for signaling whether said output voltage is greater than or less than said first voltage threshold, a second state sensing circuit having an input coupled to said output and for signaling whether said output voltage is greater than or less than a second voltage threshold, and a state transition circuit having a first input coupled to the output of said first state sensing circuit and a second input coupled to the output of said second state sensing circuit, said state transition circuit having a

  • Patent number: 6151226
    Abstract: A four quadrant power conversion topology comprising a multi-winding inductor, four switches, and four diodes is disclosed. The four quadrant power conversion is utilized in a number of power conversion devices such as a power efficient non-linear power amplifier that comprises the 4Q power conversion topology of the present invention and a switch-control-signal generator coupled to the 4Q power conversion topology. The switch-control-signal generator generates switch activation signals for driving the four switches of the 4Q power conversion topology.
