Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
198 words
Apparatus for measuring and recording human reaction time including a support for locating the center of gravity of a test subject in a predetermined position with respect to a vertically disposed reference axis and a recorder means for generating indicia proportional to the amount and direction the center of gravity of said subject deviates from said position and the amount of time required for the subject to return his center of gravity to said position characterized in that said support comprises a platform of a size to allow a normal adult human to be supported thereon, said platform being attached to the free end of a single cantilever mounted vertically disposed column, said column being supported only at its base such that said column may deflect upon deviation of the center of gravity of said subject from said predetermined position, and said recorder means includes deflection responsive sensor means and display means, said sensor means being distributed around the periphery of said column and being arranged to produce an output upon deflection of said column, said display means being connected to said sensor means and including means for recording outputs from said sensor means in a permanent form.
Claim 2
Dependent Claim
198 words
Apparatus for measuring and recording human reaction time including a support for locating the center of gravity of a test subject in a predetermined position with respect to a vertically disposed reference axis and a recorder means for generating indicia proportional to the amount and direction the center of gravity of said subject deviates from said position and the amount of time required for the subject to return his center of gravity to said position characterized in that said support comprises a platform of a size to allow a normal adult human to be supported thereon, said platform being attached to the free end of a single cantilever mounted vertically disposed column, said column being supported only at its base such that said column may deflect upon deviation of the center of gravity of said subject from said predetermined position, and said recorder means includes deflection responsive sensor means and display means, said sensor means being distributed around the periphery of said column and being arranged to produce an output upon deflection of said column, said display means being connected to said sensor means and including means for recording outputs from said sensor means in a permanent form.
Claim 3
Dependent Claim
35 words
Apparatus in accordance with claim 1 wherein said sensor means are strain gauges distributed symmetrically around the periphery of said column and said vertical axis passes longitudinally through the center of said vertically disposed column.
Claim 4
Dependent Claim
29 words
Apparatus in accordance with claim 1 wherein said column is a steel cylinder and said sensor means are strain gauges spaced 90* apart around the circumference of said cylinder.
Claim 5

Claim 6
Dependent Claim
34 words
Apparatus in accordance with claim 1 wherein said column projects upwardly from and is supported by a floor mounted support, and said platform provides a surface for supporting said subject in an upright position.
Claim 7
Dependent Claim
140 words
In apparatus for measuring and recording the magnitude of human reactions, the combination comprising: a deflectable column mounted as a vertically disposed cantilever; platform means for supporting the center of gravity of a test subject on the free end of and in a predetermined position with respect to the longitudinal axis of said column, said platforms means being of a size to allow a normal adult human to be supported thereon, and said column being supported only at its base such that said column may deflect upon deviation of the center of gravity of said subject from said predetermined position; sensor means for generating outputs proportional to and in response to deflections imparted to said column by movement of the center of gravity of said test subject, and display means for displaying and recording the outputs generated by said sensors.
Claim 8
Dependent Claim
140 words

Claim 10
Dependent Claim
66 words
In a method for measuring human reaction time, the steps comprising: aligning the center of gravity of a test subject in a predetermined position with respect to a reference axis passing through a vertical column; measuring the rate and magnitude said center of gravity deviates from said reference axis, and recording said deviations with a recording device for later examination or comparison with other similar recordings.
Claim 11
Dependent Claim
66 words
