Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 132 words
A device for registering and evaluating the response of a human subject to induced imbalance comprising a horizontal platform means for accommodating said human subject; said platform means being adapted for controlled linear displacement in a horizontal plane to cause said induced imbalance and comprising a horizontal surface mounted on linear bearings which engage rails and connected to a motor through means for translating rotation of the motor into linear motion to cause said displacement at a controlled speed and acceleration and for controlled duration and distance; means for detecting said imbalance and the response of said subject thereto and for producing signals which characterize said imbalance and response; means for transmitting said signals to evaluation, display and recording means for registering and evaluating said imbalance and response thereto by said subject.
Claim 2
Independent Claim 132 words
A device for registering and evaluating the response of a human subject to induced imbalance comprising a horizontal platform means for accommodating said human subject; said platform means being adapted for controlled linear displacement in a horizontal plane to cause said induced imbalance and comprising a horizontal surface mounted on linear bearings which engage rails and connected to a motor through means for translating rotation of the motor into linear motion to cause said displacement at a controlled speed and acceleration and for controlled duration and distance; means for detecting said imbalance and the response of said subject thereto and for producing signals which characterize said imbalance and response; means for transmitting said signals to evaluation, display and recording means for registering and evaluating said imbalance and response thereto by said subject.
Claim 3
Dependent Claim 24 words
The device of claim 1 wherein said controlled, linear displacement of said platform is at controlled speed, acceleration and for controlled duration and distance.
Claim 4
Dependent Claim 44 words
The device of claim 1 wherein said platform is provided with limit switch means to limit said displacement of the platform means and to cause said motor and means for translating to returns said platform means to its initial position subsequent to said displacement.
Claim 5
Dependent Claim 19 words
The device of claim 1 in which elevation means are provided to raise the height of said platform means.
