Abstract

See full text

A pendulum combining balanced and eccentric masses oscillates with a period that is rapidly and continuously varied by shifting the balanced masses and eccentric mass to and from the rotational axis, by controlling the amplitude of oscillation and, in a rolling embodiment, by varying the curvature of the rolling surface. Long period oscillations can be achieved without the large heights required by an equivalent conventional pendulum. The pendulum can be substantially isochronous. The pendulum can be applied to harvesting vibrational energy and especially to wave energy extraction by dynamically achieving resonance over the typical frequency range of energetic ocean swell.
