The medical research groups have been somewhat at a disadvantage in securing certain instrumentation for their various projects because usually they must rely upon large established engineering organizations where close liaison is rather difficult. A group of volunteer engineers at the Illinois Bell Telephone Company, in their own spare time, have been able to produce instrumentation for a number of these projects in a unique manner. This paper describes the SAVE (Service Activities of Volunteer Engineers) operation and one of their projects, the portable (3-ounce) self-contained, cumulative heartbeat recorder.
