Abstract
A device for awakening a sleeping person when the sleeping person attempts to sleep in a particular sleep posture includes a sensor, a time-delay circuit, and an alarm or other device for generating a stimulus for awakening the person. The time-delay circuit is designed such that it activates the alarm only when the sensor indicates the person is in the particular sleep posture for a predetermined period of time and also stops the alarm when the person stops sleeping in the particular sleep posture. The device can also be used for monitoring the sleeping person's sleep posture for diagnostic purposes.
