First Claim
1. A source of electrical energy usable with first and second conductors which carry an impressed electrical signal, the source comprising:
- circuitry for storing a predetermined quantity of electrical energy;
circuitry, coupled to said storing circuitry and couplable to the conductors, for detecting a predetermined portion of the impressed electrical signal; and
circuitry, responsive to the detecting circuitry, for discharging said stored quantity of energy into the conductors within a predetermined time period in the presence of the impressed electrical signal.

Abstract
One or more supplemental, pulsed energy sources can be used in combination with a pulsed, primary energy source which provides energy to a plurality of spaced apart loads. The loads are coupled to the pulsed, primary source by a pair of conductors. Each supplemental energy source includes circuitry for repetitively storing a predetermined quantity of supplemental energy and circuitry for detecting a start of a primary energy pulse and in response thereto, for discharging the restored supplemental energy into the conductors. Between primary energy pulses, the supplemental energy quantity is automatically restored.
