Claim Text:
1. An apparatus for preventing sleep disorders comprising: a housing; a gravitational sensor disposed within the housing and configured to generate signals corresponding to a pitch angle of a subject's head relative to an axis of gravity and a roll angle of the subject's head relative to a horizontal axis orthogonal to the axis of gravity; memory storing data representing a predetermined range of pitch angles between approximately 20° and 160° relative to the axis of gravity and data representing a predetermined range of roll angles between approximately 25° and 155° relative to the horizontal axis orthogonal to the axis of gravity; a transducer configured to create stimulus detectable by the subject; a controller coupled to the memory and responsive to the signals generated by the gravitational sensor, the controller further comprises: wherein the transducer is responsive to signals generated by the controller.
