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.
