Measuring and controlling system

Claim 1

A SYSTEM FOR COLLECTING DATA RELATIVE OF THE QUALITY OF A PRODUCT PRODUCED BY A PLURALITY OF PRODUCT MAKERS AND THEREUPON PRESENTING THE INFORMATION FOR EVALUATION, SAID SYSTEM COMPRISING, IN COMBINATION, PROCESS CONTROLLER MEANS ONE EACH FOR EACH PRODUCT MAKER TO CONTROL SAME AND EACH HAVING MEANS FOR CONTINUOUSLY MEASURING A VARIABLE CHARACTERISTIC OF SAID PRODUCT AND PRODUCING A RESPECTIVE FIRST VOLTAGE SIGNAL REPRESENTATIVE OF SUCH MEASUREMENT; MEANS FOR PERIODICALLY COMPUTING THE VARIANCE OF EACH SAID FIRST VOLTAGE SIGNAL DURING A RESPECTIVE FIRST PREDETERMINED TIME INTERVAL AND GENERATING A RESPECTIVE SECOND VOLTAGE SIGNAL INDICATIVE OF SAID VARIANCE; LIMIT SETTING MEANS GENERATING A THIRD VOLTAGE; COMPARATOR MEANS FOR COMPARING AT LEAST ONE OF SAID SECOND VOLTAGES WITH THE THIRD VOLTAGE AND EMITTING A FOURTH VOLTAGE WHEN THE LATTER IS EXCEEDED; GOAL-SETTING MEANS GENERATING A FIFTH VOLTAGE REPRESENTATIVE OF A VARIANCE GOAL; COMPUTER MEANS RECEIVING SAID SECOND, FOURTH AND FIFTH VOLTAGES AND OPERATIVE TO COMPUTE AN AVERAGE OF THE SAID SECOND VOLTAGES FOR EACH SAID PRODUCT MAKER OVER A SECOND PREDETERMINED TIME INTERVAL SUBSTANTIALLY LONGER THAN SAID FIRST TIME INTERVAL, TO COMPUTE THE FREQUENCY SAID FOURTH VOLTAGE IS EMITTED AND TO COMPARE SAID FIFTH VOLTAGE WITH THE AVERAGE OF EACH SAID SECOND VOLTAGE, SAID COMPUTER MEANS GENERATING A PLURALITY OF OUTPUT VOLTAGE SIGNALS REPRESENTATIVE OF EACH OF SAID COMPUTATIONS, MONITOR AND COMPARISON; AND MONITOR MEANS RECEIVING SAID OUTPUT VOLTAGE SIGNALS AND INCLUDING READOUT MEANS FOR DISPLAYING THE INFORMATION CARRIED BY SAID OUTPUT VOLTAGE SIGNALS FOR EVALUATION.

Claim 2

A SYSTEM FOR COLLECTING DATA RELATIVE OF THE QUALITY OF A PRODUCT PRODUCED BY A PLURALITY OF PRODUCT MAKERS AND THEREUPON PRESENTING THE INFORMATION FOR EVALUATION, SAID SYSTEM COMPRISING, IN COMBINATION, PROCESS CONTROLLER MEANS ONE EACH FOR EACH PRODUCT MAKER TO CONTROL SAME AND EACH HAVING MEANS FOR CONTINUOUSLY MEASURING A VARIABLE CHARACTERISTIC OF SAID PRODUCT AND PRODUCING A RESPECTIVE FIRST VOLTAGE SIGNAL REPRESENTATIVE OF SUCH MEASUREMENT; MEANS FOR PERIODICALLY COMPUTING THE VARIANCE OF EACH SAID FIRST VOLTAGE SIGNAL DURING A RESPECTIVE FIRST PREDETERMINED TIME INTERVAL AND GENERATING A RESPECTIVE SECOND VOLTAGE SIGNAL INDICATIVE OF SAID VARIANCE; LIMIT SETTING MEANS GENERATING A THIRD VOLTAGE; COMPARATOR MEANS FOR COMPARING AT LEAST ONE OF SAID SECOND VOLTAGES WITH THE THIRD VOLTAGE AND EMITTING A FOURTH VOLTAGE WHEN THE LATTER IS EXCEEDED; GOAL-SETTING MEANS GENERATING A FIFTH VOLTAGE REPRESENTATIVE OF A VARIANCE GOAL; COMPUTER MEANS RECEIVING SAID SECOND, FOURTH AND FIFTH VOLTAGES AND OPERATIVE TO COMPUTE AN AVERAGE OF THE SAID SECOND VOLTAGES FOR EACH SAID PRODUCT MAKER OVER A SECOND PREDETERMINED TIME INTERVAL SUBSTANTIALLY LONGER THAN SAID FIRST TIME INTERVAL, TO COMPUTE THE FREQUENCY SAID FOURTH VOLTAGE IS EMITTED AND TO COMPARE SAID FIFTH VOLTAGE WITH THE AVERAGE OF EACH SAID SECOND VOLTAGE, SAID COMPUTER MEANS GENERATING A PLURALITY OF OUTPUT VOLTAGE SIGNALS REPRESENTATIVE OF EACH OF SAID COMPUTATIONS, MONITOR AND COMPARISON; AND MONITOR MEANS RECEIVING SAID OUTPUT VOLTAGE SIGNALS AND INCLUDING READOUT MEANS FOR DISPLAYING THE INFORMATION CARRIED BY SAID OUTPUT VOLTAGE SIGNALS FOR EVALUATION.
