Abstract:
A combination comprising:a first transducer for collecting power from an oscillating recurrent natural source of energy impinging on said first transducer; said oscillating recurrent natural source of energy having a variable frequency, f1, and a variable amplitude; a switch means for selectively coupling a load across said first transducer, said switch means, when closed, causing said load and said first transducer to form a circuit designed to resonate at a frequency which is higher than f1; and said switch closure causing a relatively large transient signal to develop within said circuit; a second transducer for sensing at least one of the amplitude and frequency of the oscillating recurrent source of energy impinging on said first transducer and for producing an output signal corresponding to and representative of at least one of the amplitude and frequency of the oscillating recurrent source of energy; and means responsive to said output signal produced by the second transducer for controlling the turn-on (closure) and turn-off of said switch means.
