Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
162 words
IN AN ELECTRONIC DEVICE FOR DETERMINING THE SIMILARITY OR DISSIMILARITY OF TWO BINARY NUMBERS, THE COMBINATION OF A VOLTAGE COMPARATOR CIRCUIT HAVING TWO INPUT TERMINALS AND AN OUTPUT TERMINAL AND A COMMUTATOR CIRCUIT HAVING TWO INPUT TERMINALS, A CONTROL VOLTAGE TERMINAL AND AN OUTPUT TERMINAL, MEANS FOR APPLYING A VOLTAGE SYMBOLICALLY REPRESENTATIVE OF A DIGIT OF GIVEN RANK IN ONE OF SAID NUMBERS TO ONE INPUT TERMINAL OF EACH OF SAID CIRCUITS, MEANS FOR APPLYING TO THE OTHER INPUT TERMINAL OF THE COMPARATOR CIRCUIT A VOLTAGE REPRESENTATIVE OF THE CONTRARY OF THE DIGIT OF CORRESPONDING RANK IN THE OTHER OF SAID NUMBERS MEANS, CONNECING THE OUTPUT TERMINAL OF SAID COMPARATOR CIRCUIT TO THE CONTROL VOLTAGE TERMINAL OF SAID COMMUTATOR CIRCUIT, MEANS FOR GENERATING A VOLTAGE SYMBOLICALLY REPRESENTATIVE OF THE CARRY-OVER RESULTING FROM THE ADDITION OF DIGITS OF LOWER RANK THAN THE AFORESAID DIGITS OF SAID NUMBERS, AND MEANS FOR APPLYING SAID LAST-NAMED VOLTAGE TO THE OTHER INPUT TERMINAL OF SAID COMMUTATOR CIRCUIT.
