Alarm to Keep Motorist Awake Buzzes When Chin Drops (Dec, 1936)
Alarm to Keep Motorist Awake Buzzes When Chin Drops
Dozing at the wheel is a common cause of automobile accidents. To eliminate that cause, an inventor has devised an alarm that rings sharply at the motorist’s first nod. It is a small metal gong that is hung from the shirt collar. A trigger at the top sets off the alarm when the dozing driver’s chin drops on it.
This is actually a good idea. But if you’re tired, you probably shouldn’t be driving in the first place.
