1. A system that provides impedance compensation for a battery comprising:
- a battery connected to provide primary power directly to a first load component of a hand held terminal;
a super capacitor connected electrically in parallel with the battery, the super capacitor providing internal impedance compensation to the battery and, upon the hand held terminal being dropped and the battery resultantly being disconnected from the first load component, automatically acts as a secondary power source to the first load component; and
a regulator connected electrically to the super capacitor and battery for providing power to a second load component of the hand held terminal.

Abstract
A system for a supplemental power source for a hand held portable electronic device is provided. A super capacitor is connected in parallel to a main battery of the portable electronic device. When the main battery becomes disconnected, the super capacitor is used to power the portable electronic device. The super capacitor is also used to provide compensation for the internal impedance of the main battery and the path impedance between the main battery and the load.

11. A system that provides impedance compensation for a battery in a portable electronic device, comprising:
-
a main battery that provides power directly to a first load component of the portable electronic device through battery contacts; a super capacitor connected electrically in parallel with the battery, the super capacitor providing internal impedance compensation to the battery and, when the terminal is dropped and the battery resultantly disconnected from the first load component, automatically powers the first load component when ability of the battery to provide a suitable level of power to the first load component is diminished due to disconnection there from; and a regulator that connects the battery and the super capacitor to the portable electronic device and powers the first and second load components. - View Dependent Claims (12, 13)

14. A system that provides impedance compensation for a battery in a portable electronic device, comprising:
-
a battery that provides main power to a regulator and a first load component of a portable electronic device through battery contacts, the regulator providing power to a second load component of the device; a super capacitor connected directly to the regulator such that it maintains electrical contact with the portable device even when the device is dropped, the super capacitor provides internal impedance compensation to the battery and, when the terminal is dropped and the battery is resultantly disconnected from the regulator, automatically acts as a supplemental power source for both the first and second load components when the battery is disconnected from the regulator; and a current limiter to limit the current output of the super capacitor. - View Dependent Claims (15)

21. A method of managing impedance changes of a power source in a portable terminal, comprising:
-
providing a long-term energy storage component to primarily power a first and second load component associated with a portable terminal; securely connecting a short-term energy storage component to a regulator of the portable terminal such that the first load component remains unaffected when the portable terminal is dropped; compensating for change in an internal impedance of the long-term energy storage component by employing the short-term energy storage component; regulating voltage to the first load component from the short-term storage component and the long-term storage component; and automatically supplying power to the first and second load component from the short term energy storage component when the long term energy storage component is disconnected from the load. - View Dependent Claims (22, 23, 24)
