    Abstract: Keyboard encoding apparatus having a plurality of keys with different codes of an N digit binary code assigned to each key. A plurality of groups of contact pads are secured to a sheet of electrically non-conductive material at different key locations which are in registration with the keys. Each group of pads includes at least one power pad and a number of digit pads equal to the number of binary 1''s in the associated code. A power lead is secured to the sheet and has connections to all of the power pads. N digit leads are also secured to the sheet with different digit leads being indicative of different orders of the code. Each of the digit leads has connections to those digit pads which are indicative of a like order of the code. A keying means includes a layer of spongy conductive material at each key location disposed in a normal position a distance away from the contact pads and responsive to the actuation of any one of the keys to provide a common connection of the digit pads and the power pad at the associated key location.

    Abstract: A pattern recognition system employs an addressable memory which stores response data concerning patterns. Each input pattern is presented to the system as a binary number and each such number addresses the memory so that response data is read out of the correspondingly numbered memory address. If the data read out of the memory in response to a particular input pattern is not correct, the data in the memory is changed so that the next time that particular pattern is presented to the system, the correct response data is read out of the memory. Binary numbers corresponding to variants to an input pattern can be shifted around in an input register until they correspond to the input pattern number so that the system will respond to these variants as though they were the original input pattern. An adjustable threshold control enables an input pattern to address the memory so that the desired response data is read out of the memory even though there is a discrepancy between the input pattern number and the memory address containing that data. This provides noise immunity as well as further generalization capability. The invention herein described was made in the course of or under a contract or subcontract thereunder with the Department of the Navy.
