SUPER CAPACITOR AND CHARGER FOR SECONDARY POWER HAVING LONGEVITY FEATURES
First Claim
1. A secondary power source system for a communication device, comprising:
- a charging unit configured to receive a primary power input and restrict a current used for charging to a predetermined amount, wherein the current is part of a first output of the charging unit;
a storage unit comprising a device that stores electrical energy, the storage unit configured to receive the first output from the charging unit with restricted current and generate a second output;
a regulating unit configured to receive the second output from the storage unit and generate a third output;
a selector unit configured to perform a logical operation with the primary power input, the first output from the charging unit and the third output from the regulating unit, and to generate a fourth output; and
a shutdown unit configured to shutdown operation of the secondary power source system when the storage unit has been expended.

Abstract
A secondary power source system for a communication device includes a charging unit configured to receive a primary power input and restrict a current used for charging to a predetermined amount. The current is part of a first output of the charging unit. The system further includes a storage unit including a device that stores electrical energy, the storage unit configured to receive the first output from the charging unit with restricted current and generate a second output, a regulating unit configured to receive the second output from the storage unit and generate a third output, a selector unit configured to perform a logical OR operation with the primary power input, the first output from the charging unit and third output from the regulating unit, and to generate a fourth output, and a shutdown unit configured to shutdown operation of the secondary power system when the storage unit has been expended.
