Currently, by recovering the energy of the exhaust gases the advanced Internal Combustion Engines used in car racing have already managed to reach over 50% total effective efficiency (equal with fuel cell efficiency). However,

An aviation design that was overlooked for decades is now the rage with the latest in fighters, stealth and UAV fuselages that not only carry instruments and weapons but do some of the lifting of the craft as well.

The idea is for a key organizer. I have been always frustrated by the rattling keys with no identification for which key for which door. I made this design for a key organizer with 42 mm diameter and 80 mm height.

Well-known universal machine tool uses the non-accelerating propulsion design today. Excessive energy is never added to motor. The shift gearbox only provides needed torques /speeds by using the motor shaft standard highest torque and standard- idle speed.

ADMAR is a new innovative delineator maintenance robot that is autonomous and could be monitored and controlled remotely at a central hub with SCADA by only one person.

The ankle rehabilitation device is used to address the problem faced by people who are suffering from foot drop, which is caused by stroke. Foot drop is inability to lift the foot upwards.

The car stops. Taillights light up. Drivers see it. Pedestrians do not see it. Does the car stop??? The pedestrian does not see the taillights. Special signal lights for pedestrians on the car in front. Pedestrians will know for sure whether the car is slowing down or not.

In internal combustion engines the cam play a very important role and also takes huge impact on itself. The failure of cam is major issue which happens due to the follower, this failure is also known as the lobe failure.

Manned aircraft are quite heavy and cumbersome in some areas of aviation use. For example, aerial photography in cartography or forestry, spraying fertilizers or pesticides on medium-sized crop fields. And in these cases, unmanned aerial vehicles are a rational solution.

Drones give more secure, faster,

The present invention relates to Supplementary Seat for Public Transport with Retractable Hanging Support that provides additional sitting arrangement in available space for public transport such as buses and trains; without blocking the passengers to walk in and out of said public transport;
