Classification: CPC A | IPC A

Claim 0:
1. A system for treating a subject, comprising:
at least one acoustic sensor configured to detect a plurality of acoustic signals generated by the subject;
at least one inertial sensor configured to detect an inertial signal corresponding to a movement and/or an orientation of the subject; and
a stimulator comprising:
a stimulation system configured to deliver stimulation to a nerve which innervates an upper airway muscle; and
a controller coupled to the stimulation system, to the at least one acoustic sensor, and to the at least one inertial sensor;
wherein the controller is configured to
determine a respiratory cycle of the subject based on one or more of the detected plurality of acoustic signals, wherein said determination comprises identifying an inspiratory portion of the respiratory cycle using one or more signal processing operations that introduce a linear phase delay of between 400 to 600 ms;
determine whether the subject is asleep based on one or more of the detected plurality of acoustic signals and the inertial signal, and to
cause the stimulation system to stimulate the nerve based on the determined respiratory cycle while the subject is asleep.
