Abstract
A system for providing power to a wireless card includes power interface that provides power to a compact flash card. A boost regulator boosts the power from the power interface. A battery provides power that is summed with the power from the power interface. Moreover, a buck regulator limits the voltage of the summed power. A compact flash card can be powered by the power interface while a wireless card can be powered by the summed power.
Claims22
A power system, comprising:
- a boost regulator;
- a battery electrically connected to the boost regulator;
- wherein the boost regulator charges the battery;
- wherein the boost regulator provides a first power source;
- and
- wherein the battery provides a second power source that is summed with the first power source.
A power system for a wireless card, comprising:
- a power interface;
- a battery connected parallel to the power interface;
- a wireless card, the wireless card being powered by the power interface and the battery;
- and
- a compact flash card, the compact flash card being powered by the power interface only.
A method for providing power to a wireless card and a compact flash card, comprising:
- receiving power from a power interface;
- receiving power from a battery;
- summing the power from the power interface and the battery to yield a summed power source;
- powering the wireless card using the summed power source;
- and
- powering the compact flash card using the power from the power interface.
