Method and apparatus for harvesting energy from mechanical vibrations
First Claim
1. A method of harvesting energy from a vibrational energy source having a varying energy characteristic, including the step of varying a characteristic of a harvesting arrangement arranged to harvest the energy, the characteristic of the harvesting arrangement being varied in response to the varying energy characteristic of the vibrational energy source for a non-instantaneous time period, the method including the further step of determining changes in the varying energy characteristic over the non-instantaneous time period and adaptively controlling the variation of the characteristic of the harvesting arrangement in response to the determined changes based on an adaptive learning algorithm.
