A Pocket Size Heart Beat Radio Telemeter and Signal Decoder.

Abstract

A prototype heart beat radio telemetry system has been constructed which is suitable for use on soldiers negotiating the Army Personnel Research Establishment (APRE) Agility Course at their best speed. With only one telemeter in use at least 93% of the total number of heart beats made during an average two minute run time were detected. When two telemeters were in use simultaneously the detection efficiency fell to 63%. Interpolation of recordings, however, would count at least 99% of the total number of heart beats made. The design of the circuits is described and possible improvements are discussed. (Author)
