Sleep posture monitor and alarm system
First Claim
Patent Images
1. A device for monitoring the sleep posture of a sleeping person comprising:
- (a) a sensor to generate a detect signal in response to the sleeping person'"'"'s adopting a particular sleep posture, said detect signal being terminated upon termination of the person'"'"'s adopting said particular sleep posture;
(b) means for monitoring the detect signal for diagnostic purposes;
(c) a time-delay circuit coupled to said sensor, for generating an enable signal upon completion of a timing cycle in response to the detect signal, wherein the timing cycle is terminated without generating an enable signal upon interruption of the detect signal prior to completion of the timing cycle, wherein the time-delay circuit is constructed so as to terminate a timing cycle upon interruption of the detect signal if the duration of the interruption is greater than a maximum allowed duration and to continue the timing cycle upon interruption of the detect signal if the interruption is of a shorter duration; and
(d) means for monitoring the enable signal, wherein the enable signal is terminated upon termination of the detect signal.

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.
