Abstract: A method of dynamic speed modulation in extended braking applications in a battery-powered electric vehicle is disclosed. The method includes determining a sensed parameter of the battery, and determining a parameter threshold of the battery. If the sensed parameter of the battery is the same or exceeds the parameter threshold, decreasing the groundspeed of the vehicle to a predetermined safe speed. If the sensed parameter of the battery is below the parameter threshold, determining the change in the parameter which would be caused by the regenerative braking system at the current groundspeed of the vehicle. If the change in the parameter would cause the sensed parameter to remain, reach or exceed the parameter threshold, correspondingly decreasing or increasing the groundspeed of the vehicle to cause the sensed parameter to approximate but not exceed the parameter threshold of the battery. A controller and electric vehicle capable of same, are also disclosed.

Abstract: A wind turbine and generator apparatus for mounting on a substantially vertical fixed cylindrical object includes a stationary generator member encircling the cylindrical object and fixed to the cylindrical object. A rotating generator member encloses the stationary generator member, and is rotatably supported by the stationary generator member. A plurality of blades is mounted to the rotating generator member such that a wind contacting the blades is operative to rotate the rotating generator member about the stationary generator member to generate electrical energy.

Abstract: A horizontal axis wind turbine apparatus includes a turbine assembly comprising a generator mounted in a housing, a rotor operative to rotate the generator in response to wind forces, and a tail extending rearward from the housing, and a base adapted to be mounted on a tower. The housing is pivotally attached to the base about a horizontal pivot axis oriented substantially perpendicular to a rotational axis of the generator and located rearward of a center of gravity of the turbine assembly such that the housing can pivot upward about the pivot axis from a lowered position to a raised position. A spring is operative to exert a downward bias force on the housing to urge the housing toward the lowered position.
