ABSTRACT:
This invention relates to an apparatus for preventing snoring and for alerting when an infant sleeps on his back. The apparatus for preventing snoring is comprised of a gravity actuated sensor, a delay time circuit and a vibrator, which are placed within a housing. The apparatus is worn by its user, and the gravity activated sensor senses when it is in a predetermined range of deviation from the horizontal, and sends a detect signal to the time delay circuit. If the detect circuit lasts for a longer period than a predetermined interval, the delay time circuit activates a vibrator which irritates the apparatus user, causes him to change his sleep posture, without waking him. The apparatus for alerting when an infant sleeps on his back is comprised of two parts. The first part is comprised of a gravity actuated sensor, a delay time circuit and a transmitter, which are placed within a housing. The first part is analogous to apparatus for preventing snoring but has a transmitter instead of vibrator. The transmitter sends a signal to the second part of the apparatus, which is worn by another person. The receiver activates a vibrator which awakens the other person.
