ABSTRACT:
A sensory input discrimination system for use with a prosthetic limb such as the prosthetic lower arm includes touch pressure transducers such that information regarding pressure upon portions of the prosthesis, temperature therein, and changes in position of joints thereof will result in a sonic frequencies of characteristic pattern. Such characteristic sonic frequency patterns are communicated to the sonic proximity vibratory receptors existent upon a bone stump of an amputation site correspondent to the connection of the prosthetic limb. Such receptors will resulting generate neural impulses having a signal pattern correlating to the sonic output patterns of a system power unit that will travel from the stump to the posterior columns of the spinal cord and, therefrom, to the brain. Discrimination of such impulses will be accomplished to enable recognition of pressure, upon the prosthesis. Information relative to temperature and spatial orientation of joints of the prosthesis is, via audio chip technology, provided to the ear. One musical octave will correspond to the extent of flexure of one joint while another octave will correspond to extent of flexure, or up/down position, of another joint.
