Patent ID: 7199488

Claim:
A portable, self-contained, low-voltage power delivery and storage system for a wireless communications unit, comprising: a power bus electrically connected to a voltage regulator, for providing low-voltage electrical current to the voltage regulator; said voltage regulator electrically connected to the wireless communications unit, for providing constant, low-voltage power thereto; said power bus electrically connected to a direct power source and at least three power storage sources, for receiving and distributing a continuous flow of electrical current to the voltage regulator and wireless communications unit; said direct power source including a source of intermittently available low voltage DC electrical current; said power storage sources including: a primary, low-voltage, non-rechargeable battery with a positive terminal connected to the power bus through a current limiting resister and an isolating diode, said resistor limiting current discharged from the primary battery to a level less than the peak load of the wireless communications unit during a periodic transmission; a secondary, low-voltage, rechargeable battery with a positive terminal connected to the power bus through a current limiting resistor, said resistor limiting current discharged from the secondary battery to a level less than the peak load of the wireless communications unit during a periodic transmission; and a set of low voltage high capacity capacitors connected in series with a positive terminal of the downstream capacitor connected to the power bus, said capacitor set having a current capability sufficient to meet the peak load of the wireless communications unit during a periodic transmission.
