Abstract:
1. An interim power source comprising: an input power terminal to receive input power; an output power terminal to deliver power coupled with the input power terminal; an energy storage coupled with the output power terminal; a charging circuit coupled to the energy storage to regulate power flowing into the energy storage; a switch coupled to the output power terminal to connect a source of power being delivered from the output power terminal; and a control circuit coupled with the output power terminal to detect an input voltage associated with the input power terminal, to detect an output voltage associated with the output power terminal, and to cause the switch to connect the source of power being delivered from the output power terminal between the input power terminal or the energy storage, wherein the input power terminal is operable to receive the input power from a plurality of external power sources through a power supply unit independent of the interim power source, and supply the input power to the output power terminal.
