Densitography - A new method for evaluation of cardiac performance of rest and during exercise.

The validity of the densitographic curves obtained from the pinna of the ear for measuring the systolic intervals has been investigated in 28 subjects. This technique is found to permit the performance of noninvasive physiologic studies during physical activities, exercise tests, flight conditions, and probably long-term monitoring of critically ill patients. Densitographic curves constitute an excellent substitute by which to measure time-base intervals of the cardiac cycle when the carotid pulse tracing is not available.

GREMEX update (Goddard research engineering management exercise)

Management simulation techniques offer training in management problems. Exercise was developed to provide experience in research and development project decision making from management rather than technological perspective. Program and documentation have been revised innumerable times in past. Described report is revised version as it exists to date.

Foot pedal operated fluid type exercising device

A foot pedal operated exercising device is reported that contains a dynamometer formed of a pair of cylinders each containing a piston. The pistons are linked to each other. The upper portions of the two cylinders are joined together by a common opening to provide a common fluid reservoir and each piston is provided with a one way check valve to maintain an adequate supply of working fluid. Fluid from the driven cylinder is transmitted to the other cylinder through separate constant force spring biased valves each valve takes the predominant portion of the pressure drop thereby providing a constant force hydraulic dynamometer. A device is provided to determine the amount of movement of piston travel.
