Abstract: A variable-attitude system is applicable to the wheels for children's bicycles and mini motorbikes, essential in the early learning phase, and facilitates and speeds up correct use. The mechanism described allows progressively reducing the balance support provided by the I, supplementary wheels (3) by adjusting the pressure of a spring (8). Moreover, the wheels (3) can be eliminated, much earlier and gradually, by moving upwards a stop pin (6) or screw that raises the arm (2) that supports them, moving them progressively away from the running plane (12).

Abstract: The invention is an apparatus for generating power using inertia of a load in a moving vehicle. The apparatus includes a vessel having a volume that is capable of an expansion and a contraction, and containing a fluid under a pressure. The fluid is released from the vessel as a force is exerted by the load of the vehicle against the vessel. The apparatus includes a reservoir, operably connected to the vessel by fluid conduit. The reservoir contains the fluid under pressure until an optimum pressure is reached at which point the reservoir releases the fluid to a power generator. The power generator then generates electrical power. Excess fluid released from the power generator then returns to the vessel.

Abstract: A power generator may generate power using buoyancy having a fluid column contained by a tank having a sealable drain and a piston having a substantially hollow interior capable of being filled with a fluid. The piston has a sealable outlet, a vent, an inlet, and a lateral cross-section that is smaller than a lateral cross-section of the tank. A rod is connected to the piston and a power generator is connected to the rod. The piston operates from a first position near the top of the fluid column to a second position near the bottom of the fluid column. The piston moves from the first position to the second position as fluid is added to the inlet. The piston moves from the second position to the first position as the fluid is drained from the outlet.
