(Also, “VIP,” “Vacuum Lifting System,” “VLS”)
The system illustrated in the accompanying diagrams is intended as a supplement to the basic design of current VSTOL systems, specifically intending the practical implementation of such systems for use in consumer aircraft. The supplement is simple, involving the placement of air passages in the exhaust chambers of turbojet engines for the creation of vacuum through inlets placed within the upper chassis of the craft.

The theory behind the system’s function is twofold: (1) the induction of vacuum through an intake inlet of small cross-sectional area (relative to the cross sectional area of the exhaust) should produce a significantly high impulse of air about and through the inlet, and (2) should approximate the ...

This invention deals with an electronically controllable Variable Valve Lift System for internal combustion engines.

This system is a mechanical transmission having the capability of varying the lift of the intake and/or exhaust poppet valves while the engine is running and when varying its working conditions. Said variations being continuous and within wide limits.

The mechanical transmission includes (see Fig. 1) a regulator mechanism (RM), with two slotted holes (10), and an actuation mechanism composed by:
- a primary oscillating lever or finger follower (3), in contact with the cam (1) actuating the lift of the valve;
- a secondary oscillating lever or finger follower (4), directly acting on the poppet valve (6);
- a wedge-shaped slider device (5), ...

Imagine you are driving on a freeway and encounter a car in front that’s rapidly changing lanes with bursts of acceleration….cars in side lanes and those behind are taken by surprise and finally there’s a crash on I-402

We created a “machine” entity, Vehicle Accident Prevention System (VAPS), an embedded cognitive system that gives a car an entity. The primary function is assessing driving attitute by keeping a watch on driver stability, mental and physical and observing driving patterns to arrive at a decision.

The system monitors the following parameters :
· Vehicle Acceleration/X-Y axis maneuvers to judge the driving pattern used in the decision making process. The pattern is monitored over a preset interval to flag it, if ...

This wheelchair is inspired by racing cars and skate boards and designed for children. As an alternative to traditional wheelchair, Velomaxx is powered by arms. Therefore, every child, even kids with a disability who can’t use his/her legs, can enjoy a sportive yet comfortable ride. I wanted to create a wheelchair design that will allow kids to live their dreams of being a pilot of a race car, airplane or feel like they are in a science fiction world.

Target Market:
The target market of this wheelchair is children of age 6 to 12 years. I want them to enjoy this wheelchair, feel the adventure and have fun. The children who have a disability to use their legs ...

Wireless power systems, such as inductive power transfer (IPT), can be installed at airports to power aircraft while idling at gates and on taxiways. This would eliminate the need to run jet engines to power stationary aircraft, annually saving approximately 750 Mgallons of fuel and eliminating over 7 million mtons of carbon dioxide. Airport noise due to idling aircraft would also be significantly reduced. Such large-scale IPT systems are not being commercially produced for the airline industry.

Such a system is ideal for aircraft ground operations, since there are very specific aircraft parking locations at gates, taxiway paths, and holding locations where power "transmitters" can be installed in the tarmac. Since power transfer efficiency is inversely proportional to the ...

Yes I know this is NASA but this is really simple. Efficiency is better! Diesel engines have been around for 100 years. They have improved but are reaching a point of diminishing return. Their fundamental process is the same – combustion in a cylinder that pushes a piston. At the end of its stroke, the hot gases still have a lot of energy and that goes out the exhaust pipe. The YankeeDiesel allows that energy to expand more and produce more power. It is a radical design that would not come from the people who have been using a reciprocating piston for 100 years.

The YankeeDiesel project started in 2007 with two goals: 1) increasing the peak efficiency and ...
