Abstract:
1. A mobile communication device having a capacitor based power source comprising: device circuitry being capable of drawing a base current together with pulses of current greater than the base current; a power supply powering the device circuitry, the power supply having a source battery, a controlled pulse width modulated (PWM) power unit and a capacitor at the output of the PWM power unit, a control system utilizing at least the voltage value of the pulses of current being supplied by the capacitor to the device circuitry to determine the amount of higher voltage pulse current to be output by the PWM power unit to the capacitor, wherein when the load on the device circuitry begins drawing pulses of current from the capacitor, the voltage value on the capacitor drops from the maximum value to the predetermined threshold, and when the draw of the pulses of current end, the PWM power unit outputs higher voltage pulse current to replenish the capacitor to the maximum value.
