Abstract:
A mark-reading machine, or other record-controlled device, produces an output record from indicia on a data document, in accordance with specifications on a format document read and interpreted by the same machine. The format document is preprinted for ease of use, and may specify a number of attributes of the data document as well as control functions for the machine. Part of the format indicia may appear on another document.
Abstract:
An input pattern is assigned to one of a plurality of categories by serial associative transformations of an input data string to an output code. Substrings of the data string derived from the pattern are applied as serial search arguments to an associative store containing transformation codes for particular bit sequences. The transformation codes are then used as search arguments for an associative store containing tables for producing a second code from particular sequences of the transformation codes. Additional code levels operate similarly to output a pattern-category code. Stored control keys further control the associative-store operations. A zone-clock associative store detects significant transform-code configurations, and records how much of each pattern has been processed.
