  • Patent number: 9916770
    Abstract: Methods and systems (100) for tactile code interpretation are described herein. In an embodiment, a tactile code interpretation system (100) includes a tactile code device (102) having a plurality of tactile units (106). Each of the plurality of tactile units (106) includes a tactile code (108) for representing a notation and a corresponding acoustic code (110). The acoustic code (110) encodes information pertaining to a plurality of data blocks. The plurality of data bocks includes a start block corresponding to a start pattern, an end block corresponding to an end pattern, and one or more information blocks corresponding to information pertaining to the tactile code (108). Further, the acoustic code (110), when swiped, generates a unique sound wave to facilitate semantic interpretation of the corresponding tactile code (108).

  • Patent number: 8821049
    Abstract: An electrically-assisted mechanical Braille writer includes a main solenoid to apply force to emboss Braille onto a printing medium, and advance an embossing mechanism to the next cell. A second solenoid engages a mechanical stop to prevent one or more embossing keys from being fully depressed, to prevent kickback from the keys mechanically coupling to the main solenoid. In unpowered operation, the mechanical stop is disengaged, and the embossing keys may be fully depressed to apply force to emboss Braille and advance the embossing mechanism. Accordingly, with electrical power, the user may supply a lesser amount of force and still fully emboss Braille cells, while without electrical power, the Braille writer remains fully operational.
