| 20090129843 | Print Head for Braille Printer - A device for embossing Braille characters on an embossable substrate includes a print head and an anvil. The head containing a series of raised locations. The raised locations contain a combination of pins and are configured to print one or more columns of a Braille cell. The anvil is configured with a series of depressions for mating with the pins of the print head. Embossing occurs when the anvil or print head is moved against the other and the embossable substrate is made to conform to the depressions in the locations where a pin on the print head is positioned. | 05-21-2009 |
| 20090257805 | Digital Raised Printing Using Phase Change Inkjet Technology - A method for creating raised and special purpose printing effects using phase change inkjet technology (also known as a solid ink jet) is provided. The method includes the steps of printing a primary phase change ink jet image ( | 10-15-2009 |
| 20090274505 | Braille Writer - Mechanical braille writer. The braille writer includes a chassis supporting a plurality of finger operated keys with each key mechanically interconnected with an embossing mechanism so that depression of a key causes a corresponding one of a plurality of pins in the embossing mechanism to extend outwardly from the embossing mechanism to create a raised dot on paper adjacent to the embossing mechanism. The embossing mechanism comprises a block adapted for slidingly guiding the plurality of pins for paper contact. It is preferred that each one of the plurality of pins is straight and identical to the other pins. | 11-05-2009 |
| 20100047002 | BRAILLE EMBOSSER - A braille embosser device includes a plurality of hammers configured to strike a substrate and thereby produce thereon braille-readable projections. A controller is connected to the hammers and controls the striking by the hammers. The controller includes drivers each of which is connected to and drives a respective one of the hammers. A fault detection circuit detects a fault associated with one of the drivers and, in response to the fault, ceases the striking by the hammers. | 02-25-2010 |
| 20110103864 | BRAILLE PRINTING DEVICE - A braille printing device is disclosed. The device comprises a paper picking-up mechanism, a paper feeding mechanism, a printing mechanism, a curing light source ( | 05-05-2011 |
| 20110243629 | Process For Preparing Braille Images Using Inline Digital Coating - A method for forming Braille images on a substrate comprising feeding a substrate to an inline digital coating apparatus; forming one or more Braille images on the substrate with the inline digital coating apparatus; wherein the inline digital coating apparatus forms the Braille image by coating an ultra-violet curable phase change ink composition comprising an optional colorant and a phase change ink vehicle comprising a radiation curable monomer or prepolymer; a photoinitiator; a reactive wax; and a gellant in a single pass to form the one or more Braille images; and curing the one or more Braille images. | 10-06-2011 |
| 20120082498 | ELECTRICALLY-ASSISTED MECHANICAL BRAILLE WRITER - 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. | 04-05-2012 |
| 20140126946 | BRAILLE ERASURE MECHANISM - An improved Braille erasure mechanism may comprise a reverse-embosser or impressing mechanism to imprint a negative Braille cell. A negative Braille cell is the reverse of a normal Braille cell, with one or more dots lowered or pressed into the printing medium in an opposite direction to the raised dots of a normal Braille cell. Because the dots of a negative Braille cell are lowered past the surface of the printing medium, they may be ordinarily undetectable to the fingers of a Braille user. Accordingly, by imprinting a full negative Braille cell on top of a Braille cell to be erased, all of the previously raised dots of the Braille cell may be lowered beyond the surface of the printing medium. Any further Braille cell embossed over the erased cell will be free from corruption, because any dot not used by the new cell will remain lowered and undetectable. | 05-08-2014 |
| 20140334861 | ELECTRICALLY-ASSISTED MECHANICAL BRAILLE WRITER - 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. | 11-13-2014 |

| 20110311288 | TOOL FOR REALIZING THE KOREAN ALPHABET USING A CONSONANT AND VOWEL COMBINATION SYSTEM - A tool for implementing Korean characters using a consonant-vowel combination system, in which a simple and concise combination system capable of implementing all Korean characters using only six consonants and vowels is constructed, and thus users of the tool may realize originality, superiority, and convenience of Korean letters in daily life. The tool for implementing Korean characters using a consonant-vowel combination system is configured to implement the Korean characters using six consonant and vowel plates including: letter plate “ | 12-22-2011 |
