Abstract
An apparatus and method for sensing respiratory motion to detect sleep apnea and the like. An acoustic pulse stimulator or generator located on one side of a body sends impulses through the body to impinge on one or more sensors on the opposite side of the body. Because time delay between transmitter and receiver is determined by distance, and because distance is directly related to breathing motions of the body, measurement of the time delay will have a direct correspondence to breathing motions.
