Present invention belongs to the field of inventers, motor controllers and pulse modulated waveform generation methods and circuits. More specifically it belongs to such methods and circuits utilizing fundamental vectors. This invention features better and more efficient fundamental vectors. The proposed method offers reduced losses, increased efficiency and longer life time of inverters and motor controllers. Better approximation of a three-phase voltage waveform approaching the ideal one is a significant advantage of the proposed method. Another advantage is an easy decomposition of any point of an ideal sinusoidal voltage waveform into the fundamental vectors. This invention is particularly useful for a vector control of asynchronous AC motors.

In this exciting time of increasingly powerful computer tools only few imaginable things are left to be invented. Recently issued PC multimedia operating system Vista supports speech and hand writing recognition, visual and data streaming and networking, as well as traditional computer powers. Present invention is meant to fulfill the only gap left in computer abilities: which is comprehensive general purpose three-dimensional vision to enable computers to see the world they have changed so much. The main feature of this invention is an advanced and powerful image preprocessing method and apparatus supporting thereof.

This invention relates to the field of diesel engines operating on two-stroke cycles. This invention further relates to said diesel engines having piston compressors. Our invention has disclosed a double compression diesel engine featuring outstanding compression ratio, high thermal efficiency and large power to weight ratio. This engine is more efficient and more powerful than conventional four-stroke engines, having lesser weight and volume. This engine will operate on gasoline, as well as on diesel fuel, because of its large compression ratio.

The present invention simplifies sailing providing control of one or more sails with a wheel. The proposed system eliminates the need to control boom-footed sails separately, giving benefits of less gear and rig for short handed sailing. The wheel controlling the sails provides visible and obvious correlation between sails control action and achieved result, much like rudder control.
