Abstract:

The research and development undertaken on pulseposition and pulse-duration modulation for application in personal-telemetry systems resulted in an improved three-channel, pulse-position, amplitude-modulation-telemetry system with frequency modulation in the FM band. Further experimentation resulted in a seven-channel laboratory model using pulse-duration modulation. The sevenchannel equipment allows the monitoring of the electroencephalogram, two leads of electrocardiogram, galvanic-skin resistance, respiration and body temperature, at a distance up to 300 feet. High baseline and amplitude stability are combined with low-power consumption. New microelectronic components make it feasible to reduce the size of the seven-channel transmitting unit to 3 12 by 2 14 by 1 inch, and the weight to about 200 grams, without sacrificing performance. Tape recording of the received signal does not require expensive instrumentation recorders. A portable receiving and recording unit in a small suitcase simplifies the application for field experiments. Author
