"Knowledge of the effects of prolonged states of weightlessness on the physiological activities of gastric motility and acid secretion will aid in the planning of future space flights, since aberrations in these activities could affect the performance of astronauts. Investigation of these activities requires monitoring of the pressure and pH in the stomach and titration of the gastric contents. Since previous methods and equipment used for performing these functions are inadequate for this investigation, the equipment whose design and operation are discussed in this thesis was developed. This equipment includes an ingestible sensor capsule which is tethered in the stomach, a modulation unit which can modulate a transmitter to permit mobility of the subject, and an automatic titration unit"--Abstract, page ii.
