American Foundation for the Blind York City headquarters. Louis Braille was the Frenchman who invented the raised dot code that bears his name. On January 4, 2009, the 200th anniversary of his birth, AFB created an online gallery that includes pictures of him and digitized books and articles. AFB's main headquarters is in Arlington, Virginia. Other offices include New York City; Dallas, Texas; and Huntington, West Virginia. In 2012, AFB added VisionAware to its family of sites in partnership with the "Reader's Digest" Partners for Sight Foundation. The site folded in content from AFB's Senior Site, with new information and resources for adults of all
Six-bit character code (1965). FIELDATA was a seven-bit code (with optional parity) of which only 64 code positions (occupying six bits) were formally defined. A variant was used by UNIVAC's 1100-series computers. Treating the code as a six-bit code these systems used a 36-bit word (capable of storing 6 such reduced FIELDATA characters). Braille characters are represented using six dot positions, arranged in a rectangle. Each position may contain a raised dot or not, so Braille can be considered to be a six-bit binary code. Transmission of binary data over systems which are designed for text only can sometimes introduce problems. For example,
