Abstract: A manual mechanical leg-stepping power generating apparatus includes a leg pedal installed separately on both left and right sides of a seat pole of a bicycle, moved up and down at a position adjacent to a rider's thigh muscle, and coupled to a connecting shaft through a leg pedal link rod. Another side of the connecting shaft is coupled to a power generator shaft on the seat pole by using a support rod. The leg pedals are moved up and down alternately to drive a power generator installed in a power generator to generate electric power. When a rider rides the bicycle, kinetic energy is generated by a force applied by the rider's thigh onto the leg pedals and converted into electric energy by the leg pedals, power generator shaft and the power generator set, such that the electric energy can be supplied for the use by electric devices.

Abstract: One example of our system makes it easier to bring the wind turbines to the residential and densely populated areas. The systems can be cascaded together to supply a bigger population or area. Since most of the system is hidden, it looks better for appearance of the city/houses. It has less of noise problem near houses, and less bird and bat mortality rates, with less radar interferences, less maintenance worker hazard, and less shipping/installation cost. This technology addresses e.g. Energy and Power Management Systems for harvesting wind energy by wind-catcher tower and diffuser augmented wind turbines. For example, we discuss the placement of diffusers at the intake of the wind turbines, inside a wind-catcher tower, to significantly increase the efficiency of the wind energy capture, plus the modular design of the wind-catcher tower. Various designs for the system and components are presented here.

Abstract: By avoiding an excessive cranking torque when starting the engine by a motor/generator and expanding a motor running region, fuel economy is improved. For a large required acceleration, cranking torque Tcr is maintained to hold an initial value, while, when the required acceleration is small, cranking torque Tcr will be adjusted to decrease.
