  • Patent number: 9755458
    Abstract: A set of generators are connected in parallel using a generator bus. At least one of the generators is associated with a controller. The controller detects an overload condition on the generator bus caused by a load and disconnects an initial generator from the generator bus in response to the overload condition. The initial generator continues to run during the overload condition after disconnecting from the generator bus but alternator excitation may be removed from the initial generator. The controller initiates starting one or more additional generator without alternator excitation. The controller also initiates connecting the initial generator and the one or more additional generators to the generator bus connected to the load. Alternator excitation is applied to the initial generator and the one or more additional generator so that adequate power may be applied to the load.

    Abstract: An apparatus for harvesting energy from motion of a prosthetic limb, wherein the prosthetic limb has motion in at least one degree of freedom, may include a hydraulic amplifier mechanically coupled with a generator. The hydraulic amplifier may include an input member configured to receive an input motion when a first motion in a degree of freedom of the prosthetic limb causes pressure and motion of hydraulic fluid. The hydraulic amplifier is configured to amplify the input motion of the input member to a greater output motion. The generator is configured to convert mechanical energy of the output motion into corresponding electrical energy delivered to one of an electrical load and an electrical storage reservoir.

  • Publication number: 20130300132
    Abstract: Electrical power generation from vehicle movement where there is limited or no access to a power grid. A turbine disposed alongside, above, or under the road, harnesses the wind currents generated by a vehicle to drive an electrical power generator connected to a local electrical power system providing electrical power for roadside devices on the road ahead. Alternatively, pedals may be disposed on the road such that when a vehicle runs over them, the vertical motion of the pedals is translated into a rotational motion to drive an electrical power generator. The local electrical power system is used to supply power for roadside LEDs placed along the road ahead of the vehicle to illuminate the boundaries and perimeter, or for a roadside sign, camera, or deer whistle. The activation of the roadside devices is controlled based on whether it is day or night and the remaining charge of a battery.

  • Publication number: 20130277974
    Abstract: The Brushless Multiphase Self-Commutation Controller or BMSCC is an adjustable speed drive for reliable, contact-less and stable self-commutation control of electric apparatus, including electric motors and generators. BMSCC transforms multiphase electrical excitation from one frequency to variable frequency that is automatically synchronized to the movement of the electric apparatus without traditional estimation methods of commutation and frequency synthesis using derivatives of electronic, electro-mechanical, and field-oriented-control. Instead, BMSCC comprises an analog electromagnetic computer with synchronous modulation techniques to first establish magnetic energy and then dynamically share packets of magnetic energy between phase windings of a multiphase, position dependent flux, high frequency transformer by direct AC-to-AC conversion without an intermediate DC conversion stage.

  • Patent number: 8513828
    Abstract: A system for harnessing wind energy to charge the electric storage battery of an all-electric motor vehicle, whether the vehicle is parked or in motion. While the vehicle is being driven, a roof-mounted, internal wind turbine harnesses wind energy and causes rotation of the shaft of an electric generator mounted to an interior surface of the roof. For charging the battery while the vehicle is parked, an external wind turbine is storable in the vehicle when not in use and attaches to the internal wind turbine. Cups of the kind used in cup anemometers are attached to radial arms that extend from an external shaft of the external wind turbine and catch ambient wind currents while the vehicle is parked, causing the external shaft and the generator shaft to rotate.

  • Publication number: 20130154265
    Abstract: The invention provides a temperature measuring device with manual power supply which is substantially composed of a casing, a rolling unit, an energy converting unit, an energy storing unit, a temperature measuring unit and a display unit. After rolling or rotating the rolling unit on a plane surface, kinetic energy of the rolling unit is generated and converted to electric power through the energy converting unit and then stored in the energy storing unit. The electric power supplies the needed power to the temperature measuring device and the display unit. Thus, the temperature measuring device with manual power supply of the present invention can be provided with sufficient power at any time.

    Abstract: Vehicles of embodiments of the invention are propelled by an electric motor (DC or AC motor) coupled to one of the vehicle's axles. The electric motor is powered by two or more electrical storage devices (e.g., batteries or battery banks or capacitors). The electrical storage devices are charged by alternators driven by a rotating flywheel. The flywheel is selectively coupled to a different one of the vehicle axles, such that movement of the vehicle (caused by the electric motor) causes the rotation of the flywheel.
