A New Task for the Robot

THE robot has a new job in the Holland tunnel, in New York. His sensitive electric eye is now applied to the task of detecting the clearness of tle atmosphere and furnishing an instantanéous and accurate record of hazy or foggy conditions in the great inter-State traffic artery under the Hudson River. In applying the light-sensitive photoelectric tube to a‘ task of this kind, the chief engineer and superintendent of the Holland tunnel, which connects: New York and Jersey City, hopes to effect important. operating econdggies and to provide an additional in controlling the air conditions iiXthe | tunnel. As now experimentally used, the "electric eye" is directly connected to a recording device a quarter of a mile from the mouth of the tunnel. Impulsés from the photo-electric tube guide a pencil point over a sheet of. paper graduated in time and in volume. At any instant the supervisor knows how much haze is in the tunnel, and if the visibility decreases from any cause whatsoéver he can rélieve the situation by speeding up the fans or by putting additional fans into service. — The detector is under development by engineers of the General Dlectric Company, along lines suggested by the engineering department of the tunnel, ‘and it must undergo a lengthy test besR it is prohotinced adeqtidte for the
