The invention relates to a device () for converting the energy of the swell and of waves into useable energy, particularly electrical energy, comprising a float element (), an oscillating element () mounted such that it can move with respect to the float element, the oscillating element () being able to be set in relative motion with respect to the float element () under the action of the waves on the float element and means () for converting the movement of the oscillating element () into useable energy, particularly electrical energy, the device () also comprising braking means () capable selectively of immobilizing or releasing the oscillating element () with respect to the float element, clutch means () able selectively to couple or to uncouple the conversion means () and the oscillating element (), and control means () for controlling the braking means () and the clutch means () as the swell evolves.

A device for compensating a vibration force uses four rotating weights with parallel rotation axes. The four weights are located in a common plane P and symmetrical in pairs relative to a plane perpendicular to the plane P and passing through the line of action of the vibrational force F to be compensated. The weights of each pair rotate in opposite directions. A device for compensating a vibrational torque uses four rotating weights with rotation axes parallel to an axis D and symmetrical in pairs relative to the axis D. The weights of each pair rotate in the same direction. A real time control device includes a constant gain non-linear self-adapting Kalman filter.
