  • Patent number: 7105988
    Abstract: A piezoelectric device is formed of a supporting substrate with first and second conductive traces on a first surface. A piezoelectric material layer is laminated to the supporting substrate with a first surface of the piezoelectric material layer electrically connected to the second conductive trace and a second surface of the piezoelectric material layer electrically conducted to the first conductive trace. A protective coating is applied over the piezoelectric material layer so that at least a portion of the first and second conductive traces are exposed.

  • Publication number: 20050185809
    Abstract: An improved audio frequency speaker comprises a speaker cone suspended for movement to generate air displacement, a voice coil having at least one winding attached to the cone and a magnet having a magnetic field. The magnet is located such that at least a portion of the coil is within the magnetic field to thereby cause the coil and the cone to move when a current from an audio frequency drive signal flows through the coil winding. At least one piezoelectric actuator is secured to the cone and is adapted to receive the audio frequency drive signal. The at least one piezoelectric actuator moves the cone, at least at higher order frequencies of the audio frequency range, to thereby enhance the performance range of the speaker at the higher order frequency so that a single speaker covers the entire audio frequency range.

  • Patent number: 6485380
    Abstract: A golf club includes an electroactive assembly attached to the club and electrically tuned to capture energy from one or more vibrational modes with high efficiency. More generally, a sports implement includes an electroactive element, such as a piezoceramic sheet attached to the implement, and a circuit attached to the electroactive element. The circuit may be a shunt, or may include processing such as amplification and phase control to apply a driving signal which may compensate for strain sensed in the implement, or may simply alter the stiffness to affect performance. The electroactive element is located in a region of high strain to apply damping, and may include plural subassemblies mounted to capture energy in different planes, or to capture an asymmetric strain distribution while maintaining structural symmetry. In a ski the element captures between about one and five percent of the strain energy of the ski.

  • Publication number: 20020101135
    Abstract: The invention is directed to damping vibration, and audible noise in particular, using a hybrid actuator with active and passive damping components. In one aspect of the invention, the active component may be used to damp low frequency vibrations while the passive component is used to damp higher frequency vibrations. Also provided is a procedure for optimizing the size of each component with a minimal hybrid actuator mass. The hybrid actuator is controlled by an optimized control system.

  • Patent number: 6345834
    Abstract: A recreational board such as a snowboard incorporates strain transducers to damp a plate resonance of the board. The strain transducers are preferably located around a peripheral region to capture strain energy affecting control edges, for example steering control edges at the front and/or rear of the board. Electrical energy from the transducers is shunted to damp a targeted resonance. In a preferred embodiment the strain transducers cover a region of the snowboard adjacent one surface and extending along the forward periphery, preferably at both inside and outside edges, and are shunted with a resonant shunt tuned to a torsional or torsion-like mode of the board that is excited during steering maneuvers. The transducers may be fabricated as preassembled sheets or may be formed in the snowboard during the assembly process using sheets of piezoceramic material, or using piezo fiber or other composite constructions.

  • Patent number: 6086490
    Abstract: A baseball bat includes an electroactive assembly attached near the handle and electrically tuned to capture energy from several modes with high efficiency. More generally, a sports implement includes an electroactive element, such as a piezoceramic sheet attached to the implement, and a circuit attached to the electroactive element. The circuit may be a shunt, or may include processing such as amplification and phase control to apply a driving signal which may compensate for strain sensed in the implement, or may simply alter the stiffness to affect performance. In a ski, the electroactive element is located near to the root in a region of high strain to apply damping, and the element captures between about one and five percent of the strain energy of the ski. The region of high strain may be found by modeling mechanics of the sports implement, or may be located by empirically mapping the strain distribution which occurs during use of the implement.
