  • Patent number: 4105997
    Abstract: A method of preparation of printed text for optical character reading is disclosed. In addition, a method of checking for errors in the optical character reading of the prepared test is disclosed. The basis of the text preparation method is to add check symbols to each line of text during its preparation. The check symbols are produced by sequentially processing the ASC II code for the printed alpha-numeric characters as a dividend where the divisor is the bit sequence of a unique generating polynomial code. The remainder bits of this division operation are then translated to be check symbols which accompany the line of printed text. The basis of the check method is as follows: During optical character reading of the text, the line of information text including check symbols is processed in a routine manner to produce an ASC II code serial bit stream for the alpha-numeric character and check symbols. The alpha-numeric portion of the bit stream is then processed by the unique generating polynomial code.
