Abstract: An electrical generator including a magnetic field generator and at least one energy converter for converting energy present in fluid flows into vibrations or oscillations. The converter includes a flexible membrane having at least two fixed ends. The membrane vibrates when subject to a fluid flow. One of the electrical conductor and the magnetic field generator is attached to the membrane and configured to move with the membrane. The vibration of the membrane caused by the fluid flow causes a relative movement between the electrical conductor and the applied magnetic field. The relative movement causes a change in the strength of the magnetic field applied to the electrical conductor, and the change in the strength of the magnetic field applied to the electrical conductor induces a current flowing in the conductor.

Abstract: An energy converter for inducing vibrations of a membrane when subject to a fluid flow, and converting the vibrations into another form of energy, such as electricity. The energy converter includes at least one flexible membrane supported and/or fixed at least two points and at least one transducer. The transducer is attached to the membrane or disposed in the proximity of the membrane. When subject to a fluid flow, the membrane vibrates and creates a stress on the transducer, which induces an electrical potential.

Abstract: A mold image assembly includes a plurality of contact elements assembled in a defined space such that the contact elements are independently movable, with a first end of the contact elements collectively forming a first surface and a second end of the contact elements collectively forming a second surface. The first surface is adapted to be brought into contact with an object such that the first surface assumes an altered contour that substantially conforms to a contour of the object, and the second surface assumes a correspondingly altered contour. The contact elements are further adapted to be joined together to thereby secure the altered contour of the second surface as a mold image.
