Abstract: A quick economical re-energizing system of Electric Vehicles {EV}5 intended for replacing discharged electric batteries of Electric Vehicles by charged ones, when there are no “on-boared” means for the continuous charging of batteries, and provided said EV are suitable for the offered re-energizing system, the technique of replacing the discharged batteries by charged ones, automatically {or semi-automatically}, being equivalent to the regular known re-fueling of cars, as regarding the duration of the process and the convenience of drivers and passengers, said re-energizing being enabled due to unique capabilities deriving from a newly invented electric automotive system, like allowing all the four traveling wheels of EV to swivel about their steering axes, at 90 degrees from the travel direction, or like self-elevating and lowering the EVs body in relation to the traveling wheels, as required for the offered re-energizing process of Electric Vehicles.

Abstract: An independent Vertical Non-guided Vehicle suspension, possibly combined with a vertical driving-shaft, pure linear substantially vertical motions of the vehicle's wheels being performed by said suspension, on traveling upon rough or disrupted roads, said motions being non-guided, thus avoiding wear as occurring in the conventional vertical guided suspensions, on being subjected to horizontal forces. The pure linear vertical motions of the vehicle's wheels, tend to ensure accurate longitudinal and crosswise distances between the vehicle's wheels, resulting in decreased wear of the tires, as well as improved driving performances, by avoiding skidding of the wheels.

Abstract: An electrical vehicle for road or internal transportation, in which all driving performances are carried out merely by controlling the relative rotation speeds and tilt-angle of each driving wheel, through a programmable control system, thus eliminating any mechanical means regularly utilized for this purpose, and enabling this vehicle to be driven by a person, or automatically along guiding elements, or by remote control, or to be programmed for travelling along a predetermined course without any external guiding measures.

Abstract: A driving mechanism for bicycles and like vehicles propelled by human muscle power wherein a reciprocal pull motion at the two ends of a single flexible cord (or any other bendable element), is converted into a one directional rotary motion, the mechanism providing the possibility of obtaining different rotating speeds.
