Abstract:
A device for retarding drowsiness comprising:a housing adapted to be worn behind a user's ear, the housing having at least two side walls;an electrically conductive transverse upper cross member mounted between the side walls;an electrically conductive transverse lower cross member mounted between the side walls;an electrical circuit at least partially housed within the housing, the cross members being coupled to the electrical circuit;an earphone coupled to the electrical circuit and attached to the housing, the earphone being adapted to be fitted in the user's ear for emitting an audible alarm;a conductive disk having a circular hole which receives both of the cross members and is supported on the upper cross member, the disk having an inner diameter at the hole that is greater than a distance between the cross members to avoid completing an electrical path between the cross members while the device is in an alert position, and when the device is tilted, the inner diameter touching the lower cross members to complete an electrical path for sounding an alarm.
