It is well known that piston secondary motion affects the dynamics of the piston/ring/liner system in an internal combustion engine. A number of analytical models have been proposed to understand and control its effect on engine noise, engine friction and oil consumption. Also, tightening fuel efficiency and emissions regulations have led to engine downsizing, thereby creating new durability challenges for the piston/ring/liner system. Higher heat loads and higher mechanical loads have spurred the development of new running-in and wear-resistant coatings for improved performance and durability. These coatings are challenging to study analytically, and engine dynamometer tests must always be conducted to confirm their scuffing and wear behavior early in the development process and before production-release.

The proposed “Urban fly and ride taxi system” is composed by:

Flying modules, that are multicopters having propulsion pods, each with one or two (in tandem configuration) electric motors, each motor driving a single or multibladed rotor. They are equipped with battery and or fuel cell power packs, and a control unity being capable of flying in autonomous, programmable or fly by wire control modes.

Riding modules, that are multi wheeled ground vehicles with electric or hybrid propulsion, having central or inside wheels electric motors. They are equipped with battery and or a fuel cell power packs, and a control unity being capable of driving in road and cities, in autonomous, programmable, or in drive by wire control modes.


Pedestrian safety is of extreme importance in the new autonomous vehicle environment. While vehicle sensor technologies continue to evolve and improve, there is a need for a robust back-up to help protect pedestrians , motorcyclists, bicyclists, and pets. My idea is a small wearable electronic tag that would tell an autonomous vehicle via a common standard protocol that "Hey, I'm here." For people, it could be worn on a lanyard badge holder or integrated with personal phones and smart watches . For pets, it could be attached to a collar. The device would have a low power requirement, long battery life, be thin and compact, easily replaced, and emit a signal over a limited distance that would be recognized ...

The Integrated Coefficient Enhancement (ICE) is a unique concept that addresses vehicle dynamics during panic events. State-of-the-art safety technologies in concert with an aerodynamic/mechanical delivery devise and high tech ceramic tractive medium (TM), come together in real time to greatly improve friction forces during a panic event. The result is greatly reduced stopping distances and turning radii at any speed on most road surfaces including ice, snow, wet and dry pavement.

The ICE consists of three main aspects: Electronics, Delivery Apparatus, and Tractive Medium.


State-of-the-art safety systems such as ABS, ESC, LiDAR, and radar activate and control the ICE in real time.

Delivery Apparatus

Each of two aerodynamic/mechanical delivery units are located ...

Various mechanisms are known for lifting and moving cargo. At the same time, we (Grigori and Oleg Lishanski, US Patent No. 10,214,398 B2, Feb. 26, 2019) developed and tested a simple device that is able to economically move a load overcoming the force of gravity. The device is a platform that is supported on the supporting surface. The supporting surface can be installed vertically or at any arbitrary angle to the horizon. A generator of mechanical vibrations (electrovibrator) and a load are installed on the platform. The vibrator allows you to create longitudinal-axial elastic mechanical oscillations of the platform with a given frequency and amplitude relative to the axis of the fixed bearing surface Fig 1. When the vibrator ...

This design is for an aerodynamic drag reduction device. This device works by producing a small powerful vortex near the boundary layer of a vehicle's body. This then adds momentum to the boundary layer, allowing for the air to stay attached to a surface longer. This attached airflow, then flows in the air void at the rear of a vehicle, reducing the drag.

While this idea of using vortex generators to reduce drag has been explored before, the designs for these other devices have not been effective enough to be commonly used in the automotive industry. However, the design that we have developed has been able to be 2-3 times as effective as these other vortex generator designs.

Vortex ...
