Apparatus particularly for evaluating the functionality of man locomotive faculties
First Claim
1. A human locomotive functionality evaluating apparatus comprising a substantially rigid platform adapted to support a subject walking thereonto and exercising on said platform a force and/or pressure due to said walking;
- a plurality of force and/or pressure transducing members operatively associated with said platform and adapted to provide a corresponding multiplicity of electrical signals representative of said force and/or pressure on said platform, said apparatus being characterized in that it further comprises a hybrid processor circuitally connected to said plurality of transducing members and adapted to on-line convert onto an output display means the time-space representation of the projection on a plane of the resultant of the forces and/or pressures acting on said platform due to said walking of said subject thereonto, said hybrid processor comprising first and second RC circuit means operatively connected to outputs of sample-hold circuit means, said RC circuit means being driven by clock means and being adapted to provide at the outputs thereof an exponential signal asymptotically going to a value imposed by said sample-hold circuit means.

Abstract
It is described a man locomotive functionality evaluating apparatus comprising a rigid platform adapted to support a subject walking thereonto and exercising on it a force and/or pressure due to said walking; a plurality of force and/or pressure transducing members operatively associated with the platform for providing electric signals representative of the force and/or pressure on the platform and a hybrid processor circuitally connected to said transducing members and adapted to in-line converting on output display means the time-space representation of the projection on a plane of the resultant of the forces and/or pressures acting on the platform.
