The subject matter of the invention is a vibration-to-electric energy converter by translating reciprocating motion of vibrating elements of a vehicle to circular motion of a driveshaft of an electric generator, fitted with at least one drive unit containing a toothed gearing and at least one freewheel.

The converter according to the invention has a movable element (1) that transmits vibrations to two ends of a drive chain (3), finished with fixing elements (4) with nuts (5) used for tension adjustments and with tensioning springs (6), whereby the chain (3) interacts with a small cogwheel (7) of at least one gearing (PZ), coupled via a freewheel (10) with a large cogwheel (9) of that gearing, connected by means of a short chain (12) with a drive wheel (13) of at least one electric generator (14), where both the axis (8) of the gearing (PZ) and the generator (14) are fitted to a base (11) constituting an immovable element.

A regenerative shock absorber that include a housing and a piston that moves at least partially through the housing when the shock is compressed or extended from a rest position. When the piston moves, hydraulic fluid is pressurized and drives a hydraulic motor. The hydraulic motor, in turn, drives an electric generator that produced electric energy. The electric energy may be provided to a vehicle, among other things. The regenerative shock absorber may also provide ride performance that comparable to or exceeds that of conventional shock absorbers.

A cleaning system includes: a pump portion that includes an air chamber that is capable of drawing in air from an outside, and an oscillating body which oscillates due to vibration of a vehicle and changes a volume of the air chamber so as to discharge the air drawn in the air chamber from the air chamber; and a nozzle that is disposed to face an information collecting surface of an information acquiring portion provided in the vehicle and injects the air discharged from the air chamber onto the information collecting surface.

A system is disclosed and illustrated for converting vertical movement of a vehicle in motion into electrical energy using at least one example embodiment having a vertically-collapsible frame with a frame bias spring to expand the frame to a normal height under a predetermined weight. The frame mounts between a shortened suspension spring and the vehicle's chassis, so that it is compressed when the vehicle bounces up and down during travel. A shaft to an electrical generator is rotated by at least one, and preferably two, sprag clutch drives responsive to the collapsing and re-expanding of the frame. The generator output is available for storage in a battery to be used by an electric motor or electric accessories. Optional fly weights can be used to keep generator shaft rotation relatively constant during transition between collapsing and re-expanding phases, and vice versa.
