TEXT: Dear Sir:

I am taking the liberty to write you. I have been advised by Mr. Vaniderstine to address to you this letter. Being an electronic engineer I came to some ideas related to improving safety of driving. I hope the inventions I made might be very useful and patentable.

My ideas are now in different stages of developement: some of them have been realized in working models, others need futher research and testing. Before taking next step I would like to be sure that my inventions are in accordance with existing stand ards. Also I would very appreciate your opinion on usefulness of the inventions.

The brief descriptions of the inventions are enclosed.

Thank you for your time and attitude.

WARNING AND TEACHING DEVISE FOR IMPROVING OF

DRIVING HABITS AND FUEL ECONOMY.

This is a simple, easy-to-install devise, which is to warn drivers by indicating the excessive deceleration, acceleration and dangerous speed at turns by emitting sound signals. Such warning will teach motor vehicle drivers how to take adequate and s afe actions and to improve fuel economy. This devise can be adjustable for different levels of the controlled parameters or / and be factory-preset to the predetermined values.

This inexpensive, dashboard-mounted devise can be powered from separate battery or cigarette lighter and the installation does not require any experience.

The working model is available.

DECELERATION WARNING LIGHT.

The devise measures actual vehicle deceleration and its output controls the frequency of light flashing (preferable high-mounted brake light). This makes following vehicles drivers alert and thus reduces risk of rear-end collisions.

The devise proposed is inexpensive, small sized and easy-to-install.

There are several patents related to the given invention, which, however, differ from the proposed one those show that the problem is still actual and the solution is very desirable.

The working model is available.

SELF-ADJUSTABLE WINDSHIELD WIPER.

This devise controls the rate of windshield wiper sweeps according to intensity of rain, thus it eliminates the distraction of driver's attention and makes driving more comfortable. This is to improve traffic safety. It needs no additional sensors, such as humidity sensors or windshield transparency sensors.
