THE ELECTRIC EYE.

AMAZING DEMONSTRATION. OPERATED BY HUMAN VOICE. An amazing demonstration of the “electric eye,” or light sensitive photoelectric cell, was given recently by the Westinghouse Electric Company in the show-rooms of the Willys-Over-land Company, New York, when H. P. Davis, vice-president of the Westingh'ouse Company, from his office in the company’s Administration Building in East Pittsburg. Pennsylvania (United States of America), directed the movements of an unattended automobile in New York. As Mr Davis told the car to “go ahead,” it moved forward. Similarly, upon orders from the distant operator, the car stopped and moved backward. The lights were turned on in response to a request from the voice in East Pittsburg. This was the first time in history that an automobile in one city was controlled and moved at will by the voice of a person in a distant city. It was made possible by the “electric’eye,” or photo-electric cel! of the Westinghouse Company. This cell was placed in the trunk in the rear of the Willys car. A telephone connection was then established between Mr Davis’ office in East Pittsburg and the WillysOverland quarters on Broadway. When Mr Davis spoke, sound impulses were set up and transferred into light waves which were picked up by the “electric eye,” which in iurn operated certain relays and gave the automobile its backward and forward movement. The demonstration of this most modern form of remote control was witnessed by a large group of automolive experts, technical men and scientists from the Westinghouse Company, as well as by the general public and a group of newspaper men.
