(under subclass 534) Subject matter using a transducer of the capacitor type to detect body movement.
(1) Note. Included here are the following: (a) apparatus in which the body of a test subject rests on and, as a result of motion attending breathing, moves a sheet constituting one plate of a capacitor; (b) apparatus in which the body surface of a test subject forms one plate of a capacitor; and (c) apparatus in which movement of a test subject varies fluid pressure applied to one plate of a capacitor.
