A portable physiological recording system
Equipment was designed and constructed to monitor automatically and unobtrusively up to twelve physiological variables on a human subject engaged in a prolonged field exercise. Inputs from transducers are sampled in turn, and are encoded into 7-digit PCM. They are then recorded on a small tape-recor...
