A device for controlling the surge of electrical current demanded following the discharge of a lighting system comprised of multiple electronic flash units powered from a common source. Individual electronic flash units are re-charged sequentially by the invention after system discharge, thus limiting the current demand to approximately the level produced by a single strobe light apparatus. The power management device for large electronic flash units can be integrated into the circuits of a strobe light apparatus, a generator, inverter or battery pack itself, or it can be configured as a self-contained accessory device.

Power management device for large electronic flash units

An air purification system for subjecting air to a complex electrical field including sensors and a monitor/controller for monitoring effectiveness, operational conditions of the electrical field and the system, and ambient conditions of the air being purified. The level of the high voltage, RMS and high frequency is processed so that frequency, RMS and high D.C. can be measured at a low D.C. voltage.
