Book Description
The temperature-sensing telemetry system consists of three implanted transmitters (each with its own antenna system and receiver), a scanner to sample in sequence each receiver output, a frequency counter, digital recorder, and tape punch unit. The scanner, synchronized with the digital recorder, permits temperature recording from each of the three transmitters once every 5 minutes. The implant is an FM/FM (frequency-modulated subcarrier/ frequency-modulated transmitter) telemetry unit operating in the 88 to 108 MHz FM broadcast band. Thermistors are used as temperature sensors. Printed circuit boards are used for component interconnection and antenna; mercury batteries are used for power. The sensor, radio frequency transmitter, and batteries are embedded in an epoxy case. Before implantation the unit is calibrated in a water bath over the temperature range of 34 to 42 degrees C. The system has been used to automatically record, digitally and continuously, temperature measurements of three unrestrained rhesus monkeys (Macaca mulatta) for a period of 5 weeks.

Book Description
Proceedings are presented of a symposium on Circadian Rhythms in Nonhuman Primates at the Second International Congress of Primatoloty, Atlanta, Georgia, July 2, 1968. It contains papers on both behavioral and physiological rhythms in which the chimpanzee, baboon, and nemistrina, rhesus, and cebus monkeys were subjects. As such it represents the first attempt to consolidate the current research in this area. (Author).

Book Description
"With the advent of manned space flight, the National Aeronautics and Space Administration (NASA) has conducted intensive investigations on the physiological makeup of the human body. The last decade has seen major advances in the use of radiotelemetry in physiological research. Revolutionary developments in microelectronics are making possible smaller telemetry systems that can be wholly implanted in laboratory animals. The NASA Ames Research Center has been in the fore-front of such research and has developed many implantable biotelemetry devices now considered by many as a standard method for monitoring physiological functions in animals. This report describes biotelemetry developments at Ames, tracing the evolution of concepts underlying the accurate and reliable biotelemetry systems of today. Such systems are described in sufficient detail for the reader to select designs to meet specific needs. Through its Technology Utilization Program, NASA strives to make the results of such work widely available for the use of those outside the aerospace community. This publication is one of a series intended to achieve those objectives."--Foreword.
