Device controlled by inclination of the head of a driver preventing his falling asleep
First Claim
1. A device controlled by the inclination of the head of a driver to prevent the driver from falling asleep, said device comprising detector means for detecting the position of the driver'"'"'s head, warning means operatively connected to said detector means to receive a warning signal therefrom and adapted to emit an audible warning on receiving such signal, and a battery support for supporting a battery serving to power said device, said detector means, warning means and battery support all being housed within a housing and wherein said housing is adapted to match the contour of the ear, said detector means being adapted to pivot relative to said device by movement of finger means extending to the exterior of said housing.

Abstract
A housing is shaped and sized to conform to the user'"'"'s ear in the manner of a hearing aid. Within the housing is a position-responsive switch and a second generator responsive to the switch. An arm extends from the switch exteriorly of the housing to allow easy adjustment of the switch'"'"'s position relative to the housing. In use, the housing is positioned behind the user'"'"'s ear and the switch adjusted so that the sound generator is off. Should the user'"'"'s head nod, the sound generator will be actuated, alerting the user by both bone conducted and atmospherically conducted sound, to prevent his falling asleep.
