Patent ID: 7127288

Claim:
A circuit for maintaining consistent pulse output of a battery-powered apparatus to a load, said circuit comprising: a battery having an electrical output; an inductor, connected to the battery, for receiving the electrical output of the battery; a capacitor, connected to the output of the inductor, for receiving and storing the electrical output of the inductor, the capacitor having an electrical output; an electrode, connected to the capacitor, for delivering the electrical output to the load; and a controller programmed to periodically connect and disconnect the inductor to the battery such that a plurality of current pulses are generated charging the capacitor, the controller is also programmed to intermittently connect and disconnect the capacitor to the load causing the capacitor to discharge the electrical output of the capacitor to the load, wherein the controller limits the pulses generated by the battery and the time between the pulses generated by the battery such that the resulting average electrical current draw from the battery is within the battery's optimal discharge rate.
