Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
165 words
A load profile analyzer for determining the distribution of forces on a test body produced by the loading effect of a body covering and comprising: a. a plurality of electrically operated pressure sensors for simultaneously producing distinguishable output signals in response to different load magnitudes exerted on the test body; b. a flexible support sheet means for supporting said pressure sensors between the test body and the body covering, said sensors being in mechanical contact with the test body and each sensor being responsive only to the pressure exerted on the discrete portion of the body adjacent thereto, said flexible support sheet means being adapted to freely assume the surface contour of any irregularly contoured surface on which it is supported and to produce substantially no alteration in the distribution of forces transmitted by the body covering to the test body; and c. an analyzer means operatively connected to said pressure sensors and adapted to analyze and indicate the pressures sensed by said pressure sensors.
Claim 2
Dependent Claim
