The purpose of the program was to design, develop, and fabricate an instrument which could locate and sense loads induced on the body of a person wearing protective armor, and to compare suspensions and suggest improvements which could be incorporated in current or future load-carrying systems. The development of a Personnel Armor Load Profile Analyzer saw the attainment of a method of sensing loads, the integration and positioning of sensors in a suitable garment, a method of displaying information, and the correlation of output data to torso sensitivity. It was found that armor suspension systems could effectively be evaluated using this instrument. Static and dynamic load patterns were displayed and the shift in these patterns with articulation could be observed. The data obtained from the display could provide guidelines for improving suspension system design by determining whether a particular suspension was effective in distributing loads on the optimum load-bearing areas of the torso. The progressive electrical contact sensor approach provided a direct reading system with maximum reliability, ruggedness, and versatility. In addition, the system did not require special signal conditioning equipment. The variable inductance sensor approach produced an analog sensor output converted to a digital display.
