Basic Principle:

Simple energy conversion from MECHANICAL toELECTRICAL energy

To generate electricity using the vehicles weight (potentialenergy) as input:

When the vehicle moves over the inclined plates ,it gainsheight resulting in increasing in potential energy, which iswasted in a conventional rumble strip : this is made use of .

when the plates come down ,they crank a lever fitted to aratchet-wheel type mechanism this in turn rotates a geared

shaft loaded with recoil springs. The output of this shaft iscoupled to a dynamo to convert KINETIC ENERGY intoELECTRTICAL ENERGY.

A roller blind mechanism for winding and unwinding a rollableblind, the mechanism comprising a support element, a drivesprocket which is rotatably mounted on the support element fortransmitting rotational movement to a blind supporting member ,and a manually-movable elongate flexible drive element which

includes a plurality of interlinked tooth-engaging elements, thedrive sprocket including a plurality of flexible teeth engagable withthe tooth-engaging elements of the flexible drive element . A rollerblind mechanism as claimed in claim 1, wherein a radial extent ofthe teeth of the drive sprocket is equal to or greater than amaximum dimension of the tooth-engaging elements of the flexible

drive element . A roller blind mechanism as claimed in claim 2,wherein the radial extent is equal to or greater than twice themaximum dimension of the tooth-engaging elements of the flexibledrive element . A roller blind mechanism as claimed in claim 1,wherein the teeth of the drives procket flex in a circumferentialdirection of the sprocket

Rack and pinion gears normally change rotary motion intolinear motion, but sometimes we use them to change linearmotion into rotary motion . They transform a rotarymovement (that of the pinion) into a linear movement (that

of the rack) or vice versa . We use them for sliding doorsmoved by an electric motor . The rack is attached to the doorand the pinion is attached to the motor. The motor moves thepinion which moves the rack and the door moves

CRANKSHAFTMECHANISM

The crankshaft is a mechanism that transforms rotary

movement into linear movement, or vice versa . For example,

the motion of the pistons in the engine of a car is linear (they

go up and down).But the motion of the wheels has to berotary . So, engineers put a crankshaft between the engine

and the transmission to the wheels . The pistons of the

engine move the crankshaft and the movement becomes

rotary . Then the rotary movement goes past the clutch and

the gear box all the way to the wheels
