Vital signs monitor
TLDR
In this paper, a belt-mounted vital signs monitor is used to monitor respiratory activity and cardiac activity in order to prevent sudden infant death syndrome, or crib death, and in intensive care units or cardiac units of hospitals.Abstract:
Provision is made to monitor for vital signs, such as respiratory activity and cardiac activity. The monitoring equipment is mounted by a belt to a person being monitored. Multiple Inductance coils carried by the belt move relative to each other in response to breathing, and the associated mutual inductance changes provide sensory signals to reflect the breathing. Electrical signals indicative of such vital signs are transmitted by radio wave to a central monitor which can monitor the activity of numerous persons. A plurality of such patient units including vital signs sensors and transmitters in combination with a single central monitor may be used to monitor multiple patients. The present invention is useful in monitoring to attempt to prevent sudden infant death syndrome, or crib death, and in intensive care units or cardiac units of hospitals and the like.read more

Ultrasonic respiration/convulsion monitoring apparatus and method for its use
TL;DR: In this article, a closed loop phase lock system is used to measure changes in the air path length of continuous wave ultrasound transmitted to and reflected from (the chest/abdomen area of) a subject, and provides an output change signal proportional to changes in airpath length caused by respiratory effort of the subject.
