Abstract: There is provided a vehicle having a drive system. The drive system includes an engine for providing electrical power for propelling the vehicle, an electrical energy storage device, a first motor for driving a rotation of a first shaft of the vehicle, and a second motor for driving a rotation of a second shaft of the vehicle. The drive system is configured to operate in a first mode, wherein in the first mode, power for each of the first motor and the second motor is provided exclusively by the electrical energy storage device.

Abstract: A vehicle drive system comprising three motor/generators, an engine and an electrical energy storage device. The system is arranged so that two axles can be driven at the same time. Each axle can be driven using power generated by the engine or provided by the electrical energy storage device. The system can also be configured to drive one of axles using mechanical power from the engine.

Abstract: This invention proposes a cross-flow turbine design with airfoil blades and self-alignment mechanisms. The airfoil blade self-alignment mechanisms rotate the airfoil blades at half of the turbine main shaft's speed and dynamically flip the blades after reaching the windward position to realign the airfoil blades or reset the attack angle of each airfoil blade so that the airfoil blade feathers the fluid flow at the windward position, generates maximum drag force at or near the leeward position, and produces both maximum lift and drag forces in between.

Abstract: A suction tape with a large number of miniature vacuum suction cups on one side or both sides is invented here. The suction tapes have many of the advantages of the double-sided adhesive tapes, hook-and-loop (Velcro) tapes, and vacuum suction cups without their disadvantages.

Abstract: An integrated mouse and pad pointing device is thin and compact that can be built into a laptop computer or other portable computational devices such as a personal data assistant (PDA) or a cell phone with a cursor to replace the cursor control devices such as the touch pad or the pointing stick. This integrated mouse and pad pointing device has a mouse sliding in a slot of a pad plate while the pad plate slides relative to or rotates about a stationary base plate. By sensing the movement of the mouse in the slot relative to the pad plate and the movement of the pad plate relative to the stationary base plate, the movement of the mouse and hence the cursor is determined. This mouse works like a conventional mouse so it is ergonomically easy and accurate to use to control the movement of the cursor.
