Claim 1
Independent Claim
165 words
A PRECISE POSITIONING SYSTEM FOR AN ENERGY BEAM COMPRISING A PLURALITY OF PARALLEL, EQUALLY-SPACED CONTROL MEANS INTERPOSED IN THE PATH OF THE BEAM, EACH OF SAID CONTROL MEANS OPERABLE TO PRODUCE AN ELECTRICAL OUTPUT PULSE RESPONSIVE TO THE IMPINGEMENT OF THE BEAM THEREUPON, COUNTER MEANS OPERATIVELY CONNECTED TO THE OUTPUT OF SAID CONTROL MEANS, MEANS FOR TRANSFORMING THE SETTING OF SAID COUNTER INTO AN ANALOG OUTPUT VOLTAGE, AN ANALOG AMPLITUDE COMPARATOR OPERATIVELY CONNECTED TO THE OUTPUT FROM SAID TRANSFORMING MEANS, ADAPTED TO RECEIVE AN ELECTRICAL INPUT SIGNAL AND OPERABLE TO PRODUCE AN ERROR SIGNAL REPRESENTATIVE OF THEIR DIFFERENCE, DEFLECTION CONTROL MEANS FOR THE BEAM OPERATIVELY CONNECTED TO SAID COMPARATOR, SAID DEFLECTION CONTROL MEANS INITIALLY OPERABLE TO RECEIVE THE INPUT SIGNAL TO MOVE THE BEAM AND SUBSEQUENTLY OPERABLE TO REPOSITION THE BEAM IN RESPONSE TO THE ERROR SIGNAL FROM SAID COMPARATOR, AND A POLARITY COMPARATOR OPERATIVELY CONNECTED TO SAID AMPLITUDE COMPARATOR FOR DETERMINING THE POLARITY OF THE ERROR SIGNAL WITH REFERENCE TO THE PRECEDING INPUT SIGNAL.
