Publication number: 20100194117Abstract: Electrical energy is produced by harvesting mechanical energy in the form of vibrations which are generally present in tools during the process of drilling oil wells. Electrical energy production is based on the Faraday induction principle whereby changes, i.e., movement, in magnetic flux through a coil induce an electric current through the coil. The changes in magnetic flux are produced by relative motion between at least one set of magnets and at least one coil. In particular, as the flux lines change due to the movement of the magnets, they remain perpendicular to both the direction of motion of the magnets as well as a planar or cylindrical surface defined by the coils. As a result, output for a given size of device is enhanced. Further, flexibility in adapting device form factor to particular shapes is enhanced. For example, a relatively flat device may be implemented using flexural bearing support of the magnets and coils on a printed circuit.Type: ApplicationFiled: February 5, 2009Publication date: August 5, 2010Applicant: Schlumberger Technology CorporationInventors: Jahir A.

Patent number: 7755224Abstract: A system and method for producing electricity through the action of waves on floating platforms. The hydraulic force of the water in the waves causes the platform to create a series of reverse incline planes. The system adjusts or tunes the frequency of various components in relation to the natural frequency of the waves. The system has a mass carried on a track that moves relative to the track to create kinetic energy. One feature is to have the track and the mass tuned to the hull. Another feature is to tune the track and mass and the hull relative to the waves to increase power generated. In addition, the system has a microprocessor in one embodiment, that takes input related to waves, the mass, and the floating platforms and actively tunes parameters to increase the power generated. As a mass moves down the reverse incline planes, it gains mechanical energy, which is then converted into electrical energy.Type: GrantFiled: March 27, 2008Date of Patent: July 13, 2010Inventor: Glenn Beane

Patent number: 7683507Abstract: A tubular linear generator comprises an elongate translator, containing a series of permanent magnets and one or more annular coils (not shown) contained within and affixed to a ferromagnetic sleeve. Relative movement between the translator and armature causes the generation of electricity in the coils. The sleeve is contoured in terms of permeability around its circumference at one or both its ends, as shown at, in order to reduce cogging forces between the sleeve and the permanent magnets along the translator.Type: GrantFiled: January 11, 2006Date of Patent: March 23, 2010Assignee: Trident Energy LimitedInventor: Hugh-Peter Granville Kelly

Patent number: 7669532Abstract: Projectile fuze setback generator power source apparatuses and methods of use and manufacture are disclosed. An explosive projectile contains a fuze with a setback generator and associated fuze electronics. Upon initiation of projectile launch, the setback generator produces a voltage for use by the fuze electronics during flight. The setback generator includes a magnet maintained in place within a surrounding coil by a fastener. When a projectile is fired, rapid acceleration thereof causes the fastener to break and the magnet to be displaced longitudinally within the surrounding coil, which decreases the magnetic field and induces a current in the surrounding coil. The induced current produces a voltage that is stored in a capacitor operably coupled to the setback generators which then is used to power the fuze electronics during flight.Type: GrantFiled: November 17, 2006Date of Patent: March 2, 2010Assignee: Alliant Techsystems Inc.Inventors: Scott D.
