Abstract

Abstract A learning aid for the language handicapped in which phonemic language sounds are programmed onto light-sensitive film by a recording system, and played back by a playback system which activates a plurality of vibrating bimorph pins which represent the specific phonemic language sounds and tactually stimulate the skin of the person using the learning aid. The recording system includes a plurality of individual light sources and fiber optic tubes, vertically spaced apart adjacent the film, and a recording motor which advances the film past the light sources and fiber optic tubes. Selected vertically spaced-apart channels are exposed in the film for predetermined periods of time, the patterns thus recorded on the tape being detected by a similar fiber optic-light source detection means for activating selected ones of the vibrating pins in the playback system.

Claim 1
Independent Claim 210 words
A learning aid for the language handicapped comprising: an elongated film strip having a plurality of horizontal, vertically spaced-apart exposed portions of a selected length representing phonemic language sounds; a light source; a plurality of vertically spaced-apart fiber optic tubes disposed adjacent said light source; a plurality of phototransistors coupled to said fiber optic tubes and responsive to light transmitted therethrough; a pair of spaced-apart film reels disposed on adjacent sides of said light source for supporting the film strip between the light source and the fiber optic tubes; a motor control coupled to said film reels and said phototransistors for advancing the film strip and activating the phototransistors a plurality of vibrating pins coupled to the output of said phototransistors and responsive thereto, said horizontal exposed portions of the film strip and said fiber optic tubes being spaced apart at corresponding vertical positions so that light radiated from said light source and passing through said exposed portions of the film strip is detected by a corresponding plurality of fiber optic tubes and transmitted to said phototransistors, thereby selectively activating corresponding ones of said plurality of vibrating pins; and a clock generator coupled to said vibrating pins and responsive to said phototransistors for vibrating said pins at a set frequency.
Claim 2
Dependent Claim 210 words
A learning aid for the language handicapped comprising: an elongated film strip having a plurality of horizontal, vertically spaced-apart exposed portions of a selected length representing phonemic language sounds; a light source; a plurality of vertically spaced-apart fiber optic tubes disposed adjacent said light source; a plurality of phototransistors coupled to said fiber optic tubes and responsive to light transmitted therethrough; a pair of spaced-apart film reels disposed on adjacent sides of said light source for supporting the film strip between the light source and the fiber optic tubes; a motor control coupled to said film reels and said phototransistors for advancing the film strip and activating the phototransistors a plurality of vibrating pins coupled to the output of said phototransistors and responsive thereto, said horizontal exposed portions of the film strip and said fiber optic tubes being spaced apart at corresponding vertical positions so that light radiated from said light source and passing through said exposed portions of the film strip is detected by a corresponding plurality of fiber optic tubes and transmitted to said phototransistors, thereby selectively activating corresponding ones of said plurality of vibrating pins; and a clock generator coupled to said vibrating pins and responsive to said phototransistors for vibrating said pins at a set frequency.
Claim 3
Dependent Claim 25 words
