    • 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.
    • 电动机械盲文笔记本电脑包括一个主电磁线圈,用于向打印介质上压​​印盲文,并将压花机构推进到下一个单元。 第二螺线管接合机械止动件以防止一个或多个压花键被完全压下,以防止从机械地联接到主螺线管的键的反冲。 在无动力操作中,机械止动器脱离,并且压花键可以被完全压下以施加压力以浮雕盲文并推进压花机构。 因此,通过电力,用户可以提供较少量的力并且仍然完全压制盲文单元,而在没有电力的情况下,盲文写入器保持完全可操作。

    • Systems for forming three-dimensional marking material images on moving substrates include a print head arranged about a media path by which the substrate passes the print head at a predetermined media velocity. The jets marking material at a predetermined velocity onto the substrate surface to form a three-dimensional marking material image. A firing time of forming a first layer of marking material may be different with respect to a print run start time than a firing time for ejecting marking material for forming successive layers. The firing time may be adjusted by advancing or delaying the firing time with respect to an initial firing time for forming the first layer. The advance or delay may be calculated by a processor, and the calculation may be fed to a time advance/delay buffer contained by the print head.
    • 用于在移动基板上形成三维标记材料图像的系统包括围绕媒体路径布置的打印头,通过该打印头基板以预定介质速度通过打印头。 射流以预定的速度将材料标记到衬底表面上以形成三维标记材料图像。 形成第一层标记材料的烧成时间可以相对于打印运行开始时间而不同于用于喷射用于形成连续层的标记材料的点火时间。 可以通过相对于用于形成第一层的初始烧制时间推进或延迟烧制时间来调节烧制时间。 提前或延迟可以由处理器计算,并且计算可以被馈送到由打印头包含的时间提前/延迟缓冲器。

    • A remote Braille education system and device is disclosed. In one embodiment, a remote Braille education system includes a first computer system at a first location, second computer systems associated with visually impaired individuals at a second location, and a server. The first computer system includes an input device, and a display device, and each of the second computer systems includes an electronic Braille device(s). The input device is configured for communicating a first set of characters to the electronic Braille device via the server. The electronic Braille device is configured for embossing the first set of characters on a printing medium. Furthermore, the electronic Braille device is configured for transmitting a second set of characters inputted by the visually impaired individual(s) via the server. The display device is configured for displaying the second set of characters received from said one or more of the second computer systems.
