Abstract
1529219 Communicating with the blind BALL BROS RESEARCH CORP 28 Oct 1975 [29 Nov 1974] 44430/75 Heading G5G Information is presented non-visually from a device, such as a calculator, as a series of pulses, each pulse being of the same duration and the number thereof representing the information. As described, on operating an “output” key on the keyboard of a calculator, a multivibrator 71 is triggerred from its usual “1” state to a “0” state to load a BCD representation of the most significant non-zero digit, output from IC25 in seven segment form and recoded by converter 37, into counter 39. A multivibrator 41 is enabled once if a one is loaded, twice if a two,…,ten times if a zero, to provide respectively one, two, …,ten, 125 ms. duration 600 Hz pulses, each pulse separated from the next by 125 ms. Successive digits are then selected, either automatically using timer 59 or manually. Overflow is indicated by a 600 Hz pulse immediately the “=” rather than the “output” key is operated. On operation of a “sign” key a 600 Hz pulse signifies a negative, and no pulse a positive number. A decimal point is indicated by a single 300 Hz pulse. Adaption of the apparatus to provide a tactile output instead of the audible signals from speaker 19 is envisaged.
