Employing a team composed of physicians, electrical engineers, and specialists in physical education, significant dynamic physiological data has been gathered by means of radiotelemetry from athletes undergoing strenuous effort, participating in team sports, and from spectators viewing football games. Using a transistorized A.M.-F.M. transmitter carried in a padded compartment strapped comforta...

The radio-telemetering capsule (radio-pill) has been used to study the return of motility in the small bowel after vagotomy with a drainage procedure, gastric operations not involving vagotomy, and non-gastric operations. Small intestinal movements returned in about 10 hours after vagotomy, about four hours after the various gastric operations, and within one hour in those operations not involv...

Traditionally telemetering systems are based on telephone and similar voice-grade channels. Today new channels such as radio or distribution line carrier (DLC) open new possibilities. The most discussed telecommunication channel is the data highway. It is formed by the combination of cable and of optical fibre networks. In many countries the utilities themselves are involved in the development ...

The applicability of telemetering devices in patient care and biomedical research is extended by the introduction of infrared (IR) light communication techniques. Research in this field demonstrated a particularly interesting potential for a multichannel/multipatient monitoring system comprising stimulation, remote control of physiological functions or drug delivery, and patient location. Compa...
