Abstract: A monitoring system for monitoring detectable intermittent signals generated by a living being. In one embodiment, a pregnancy monitoring system monitors fetal heat beat and/or uterine contractions. A belt is configured to fit around the abdomen of a pregnant woman, with belt ends fastened together at her back. A number of sensors are mounted on the belt to detect fetal heartbeat and transmit corresponding electrical systems, preferably by wireless means, to a distant monitoring station. At least one uterine contraction sensor may also be mounted on the belt for detecting uterine contractions and transmitting a corresponding electrical signal to the monitoring station. In a second embodiment, an apron or jacket for placement in tight, uniform contact over the chest contains a plurality of sensors for detecting cardiac signals. These electrocardiographic signals are transmitted by a wireless transmitter to a distant, central monitoring system to produce a valid data signal at the remote station.
