Book excerpt: The art of physiological telemetry is borderline in three areas: (1) sensors, (2) transmitter, (3) data processing. This study assessed the AMRL 3-channel personal telemetry from all three aspects. Analysis of the records transmitted from men in various graded intensities of physical activity revealed that of the three physiological variables (respiration, EKG, and temperature), respiration was the least valid. Torso circumference changes sensed by rubber tube strain gages proved superior to the impedance method for measuring respiration. Some tentative findings on a stress interview study reveal the telemetry method to have promise. It was shown that the major difficulty preventing widespread use of physiological telemetry in significant field situations is the lack of a practicable high-speed data processing system which can distinguish and utilize the occasionally valid physiological signal emersed in artifact or noise produced by movements and changing environmental influences. The solution to the artifact problem is first to sense and utilize movement and environmental influences to gate out and to correct the physiological data and second to develop automatic editing apparatus and computer programs for recognition and selection of the valid signal patterns.

Available in PDF, EPUB and Kindle. Book excerpt: A personal telemetry system using the pulse position modulation technique was developed. The laboratory model transmits heart rate, respiration rate, and body temperature within a range of 100 feet. Compared with FM - FM Systems this system has the advantage of very low power consumption (20 milliwatts), light weight (6 ounces with batteries for 80 hours continuous operation), small size (4-3/4 by 3-1/2 by 1 inches), and sufficient accuracy and stability (2 percent baseline stability) for physiological measurements. An inexpensive, small, singletrack tape recorder may be used for recording; and an extremely simple and inexpensive playback system can be used for scope display. Although more complex equipment is required for the playback system to standard penwriters, this penwriter decoding unit is not any more complicated than standard FM discriminators. Simple, reliable, switching-type circuits which work over a wide temperature range are used, and there is no proble with crosstalk between channels. The limitations of this personal telemetry system are: (a) the frequency capability for each channel is 0 to 40 cps; (b) it is limited to a maximum of 6 channels; and (c) special playback equipment is required.
