Abstract:
1. A electrical power generating system comprising: a spring system that stores stored energy, the spring system having an input for recharging the stored energy and an output for releasing the stored energy, wherein the spring system includes a sensor that generates a monitor signal based on a status parameter of the spring system and wherein the spring system releases the stored energy in accordance with an output control signal; a generator, coupled to the output of the spring system, that converts the stored energy of the spring system into output electric power; a spring recharge module, coupled to the input of the spring system that includes a supplemental energy source and an electric motor that operates based on input electric power from the supplemental energy source to recharge the stored energy of the spring system in response to a recharge control signal; and a control circuit, coupled to the spring system and the spring recharge unit, that generates the recharge control signal and the output control signal, based on the monitor signal.
