Abstract

A system may regulate voltage supplied from a power source to an integrated circuit and/or an inertial device. A minimal voltage may be maintained in the integrated circuit by temporarily cutting off current to the inertial device to supply surges of voltage to the controller. Optionally voltage may be smoothed between said surges for example by adding capacitance and/or a current restrictor.

Claims

1-35. -35. (canceled)

36. A method for increasing a voltage potential available to a high voltage device sharing a power source with a high current device comprising:

producing transient high voltage surges in the output of the power source by repeatedly cutting off power to the high current device during predetermined spaced apart time periods;

storing energy during said surges;

releasing said stored energy when a voltage output of said power source falls below a threshold voltage needed to maintain functioning of said high voltage device.

50. A system for distributing power among a plurality components of a portable device comprising:

a first circuit powering a high current device;

a second circuit powering a high voltage device; and

a power distributor connected to a power source, said power distributor configured to;

supply to said first circuit, higher current pulses of power from said power source having sufficient energy to power said high current device, and

at least partially cut off power to said first circuit between said pulses to produce voltage surges having sufficient energy to power said high voltage device at a higher voltage potential than the potential of said higher current pulses.
