  • Patent number: 4117265
    Abstract: A sound-to-optic translator system for the hard-of-hearing is disclosed. Light-emitting diodes of different colors provide sources of light that are hyperoptically (out-of-focus) located directly in front of the pupil of the eye and along the normal line-of-sight to project overlapping color discs onto the macula area of the retina to be sensed by the cones. The diodes are supported by a T member having a width approximately one-half or less than the diameter of the pupil under normal reading light intensity and positioned at less than distance of focus of the eye. Audio frequencies are separated into a plurality of bands by bandpass filters and outputs of the respective filters drive respective diodes to hyperoptically transmit colors onto the macula.
