Processor controlled energy harvester based on oscillating weight type energy collectors

Abstract

Computer processor controlled energy harvester system. The system uses a plurality of oscillating weight type energy collectors, each configured to store the energy from changes in the system's ambient motion as stored mechanical energy, often in a compressed spring. The energy collectors are configured to move between a first position where the energy collector stores energy, to a second position where the energy collectors release stored energy to a geared electrical generator shaft, thus producing electrical energy, often stored in a battery. A plurality of processor controlled electronic actuators, usually one per energy collector, control when each energy collector stores and releases energy. The processor can use accelerometer sensors, battery charge sensors, and suitable software and firmware to optimize system function. The system can use the energy for various useful purposes, including sensor monitoring, data acquisition, wireless communications, and the like, and can also receive supplemental power from other sources.
