Already the war has produced some strange inventions. Among them is a device to keep you awake, writes the "Evening Standard" reporter.
It is attached to the eyelid, and is connected by wires to a battery carried in the pocket. Should the eye close, the circuit is made and an alarm is sounded.
This invention, it is claimed, will prevent car-drivers, sentries, or airmen from falling asleep. Another invention is a method of illuminating maps and notebooks in the dark, leaving them invisible to anyone in the air.
A portable raft is another invention just patented. This is equipped with a detachable seat and hinged rowlocks for oars, and is described as "suitable for taking on a sea voyage in these days of the submarine menace."
