Abstract: A monitor for monitoring motion wherein a light source is positioned a distance from a light conductor and the distance between the light source and the light conductor is varied in response to motion. The light received by the light conductor is used to provide output indications indicative of the monitored motion.

Abstract: An apparatus adapted for use with a plurality of cable pairs for placing a test condition on a selected cable pair including a cable pair tester and means remote from the cable pair tester for supplying a cable pair command code and a test condition command code. The cable pair tester includes a portion connected to each of the cable pairs with electrical continuity being interrupted between the cable pairs and the cable pair tester. The cable pair tester is adapted to establish electrical continuity between a selected one of the cable pairs and the cable pair tester in response to receiving a cable pair command code uniquely identifying the selected cable pair. The cable pair tester places the test condition on the selected cable pair in response to receiving the test condition command code.

Abstract: A respiration monitor for monitoring respiration of an individual comprising a sending light conductor and a receiving light conductor. The sending light conductor and the receiving light conductor are held in a position generally near a portion of the individual which moves in response to the respiration motion of the individual. More particularly, the ends of the sending light conductor and the receiving light conductor are spaced a distance apart and positioned so that the distance between the end of the sending light conductor and the end of the receiving light conductor varies in response to respiration motion of the individual. A light source emits light which is received by the sending light conductor and transmitted therethrough across the distance between the ends of the sending light conductor and the receiving light conductor, such light being received by the receiving light conductor and transmitted therethrough.
