SPRING-POWERED EMERGENCY ELECTRICAL SUPPLY

An emergency power system for operation during loss of power on power mains comprises a spring-driven energy storage unit (ESU) and a generator. The ESU enters a generator mode responsive to a power outage state of a power sensor, during which mode unwinding of the spring drive powers the generator....

Zusammenfassung:	An emergency power system for operation during loss of power on power mains comprises a spring-driven energy storage unit (ESU) and a generator. The ESU enters a generator mode responsive to a power outage state of a power sensor, during which mode unwinding of the spring drive powers the generator. After power is restored to the mains, a preferred embodiment automatically rewinds the spring using the generator as a motor.
