ABSTRACT:
A distance measurement device and method for measuring a distance between two reference points comprising a housing, a base, and a flexible member curving therebetween. The flexible member housing end is allowed to slide in a slide track in the housing. The housing also comprises sensors that detect the position of the flexible member housing end relative to the housing. The distance measurement device measures the distance between the two reference points by engaging the first reference point with the housing and engaging the second reference point with the flexible member apex. As the distance from the housing to the flexible member apex changes, the flexible member housing end slides in the housing slide track. There is a unique correlation between the location of the flexible member housing end and the distance to flexible member apex, and thus the second reference point. Using the information gathered by the sensors and the known dimensions of the housing, the distance measurement device thus measures the distance from the first reference point to the second reference point.
