(WO 2003/032889) LASER DEVICE FOR GUIDING BLIND PEOPLE Inventor VRAPI, Arben Here is presented a guiding device for blind people. The device comprises a laser beam emitter and a set of several detectors focused in the laser ray path but each with a different view field. Depending on the distance of the surface where the laser beam has pointed only a detector is ON (the one with the proper field of view) and this detector sends a signal to a sound device, which emits an audible sound. Each detector corresponds to a certain distance and controls the proper frequency of the sound in order for the person to identify the distance by the device's output sound.

2. (WO 2003/029076) AN AUTOMATIC RESCUING SYSTEM FOR AIRCRAFT PASSENGERS Inventor VRAPI, Arben This invention provides an automatic system for rescuing passengers from an aircraft in danger. The aircraft is constructed with a removable fuselage basement (20), which in case of any anomaly is pulled out of the aircraft with the means of two main parachutes (51). Once the basement is out of the aircraft's body, automatically the chairs (40) detach from this basement and individual parachutes (45) are opened. For farther safety the chair legs are equipped with shocks to reduce the impact with the ground and with means of floating for in-water landing.

3. (WO 2003/021095) TWIN PISTON ENGINE Inventor VRAPI, Arben This invention presents a twin piston engine comprising a cylinder opened at both ends and two pistons that move in opposite directions. The bottom piston is connected to a three-throw crankshaft through an inline rod.The top piston is connected through a modified rod to the connecting branch of the two side rods and through these rods to the crankshaft.

4. (WO 2003/018147) EASILY STEERED SKATEBOARD Inventor VRAPI, Arben This invention presents skateboard apparatus with higher turning capabilities. The skateboard apparatus comprises a board for supporting a user, a first wheel assembly coupled near the back end and a second wheel assembly coupled near the front end. The wheel-supporters in the second wheel assembly are welded to worms and a nut is attached to the lower surface of the board. When the user gives pressure on a certain side of the board the nut tents to move downwards rotates the worm and changes the rotational direction of the wheels.

5. (WO 2003/014540) THE FILTRATION OF CAR EXHAUSTES GASES Inventor VRAPI, Arben A waste gas purifying apparatus comprising a U-Shaped pipeline (1) with a filter (2) made of sponge material that is continually under a flow of oil. A pump (9) is used to pump the oil from the oil reservoir (3) to an oil-spreading device (11) and from there onto the filter (3) made of sponge material. The oil absorbs all the soluble components of the waste gas.

6. (WO 2003/011429) THE FILTRATION OF INDUSTRIAL FUMES Inventor VRAPI, Arben This is a natural filtration system that comprises a corridor system where the fumes are driven by the means of a ventilating process so that they can cover a longer course before they go out in the atmosphere. Inside these corridors is simulated an artificial rain so that all the soluble gases or substances are washed away by it.

7. (WO 2003/004114) ROLLER SKATE ALL-WHEELS BRAKING SYSTEM Inventor VRAPI, Arben A brake assembly for in-line roller skates. The brake assembly operates on all wheels. Each brake member is pivotally attached to chassis. When the skater presses the toe plate, main link member moves rearwardly. At this very moment, brake-rendering members, which comprise arms being pivotally attached to main link member and propeller-shaped elements being pivotally attached to chassis, are actuated so as propeller-shaped elements push the brake members, positioned on both sides, to come into contact with their corresponding wheels in order to realize braking event.

8. (WO 2002/089932) ROLLER SKATE DYNAMIC BRAKING SYSTEM Inventor VRAPI, Arben A brake assembly for in-line roller skates including a pair of bracket-shaped brake elements positioned over the two rear wheels of each skate. The rearmost wheel is pivotally connected to its preceding wheel by link members so as to let the rearmost wheel make upward movement. When braking is desired the skater lifts the forward part of the boot so his/her weight is positioned over the two rear wheels and the rearmost wheel in turn is shifted upward position while remaining in contact with the ground and contacts the rear bracket-shaped brake element. The rear part of arm, in which is accommodated the bracket-shaped brake element, is shifted upward position and as a result, the forward part of the arm is lowered downward position and this ...
