Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
62 words
THE METHOD OF REDUCING THE STATISTICAL FLUCTUATIONS OF THE CONTROLLED VARIABLE IN FOLLOW-UP SERVOSYSTEMS WHICH COMPRISES DERIVING FROM THE CONTROLLED VARIABLE A PLURALITY OF PILOT SIGNALS WHOSE RESPECTIVE FLUCTUATIONS ARE MUTUALLY UNRELATED; PRODUCING RESPECTIVE ERROR SIGNALS FROM SAID PILOT SIGNALS; COMPARING SAID ERROR SIGNALS; AND SELECTIVELY APPLYING THE ONE ERROR SIGNAL OF THE SMALLEST ABSOLUTE MAGNITUDE FOR SERVOCONTROL OF THE CONTROLLED VARIABLE.
Claim 2
Independent Claim
62 words

Claim 3
Dependent Claim
120 words
IN A FOLLOW-UP SERVOSYTEM OF A TRACKING RADAR HAVING SERVOCONTROL MEANS FOR VARYING THE CONTROLLED VARIABLE CONSTITUTED BY THE ANGULAR POSITION OF A RADAR ANTENNA AXIS, THE COMBINATION OF MEANS FOR REDUCING THE STATISTICAL FLUCTUATIONS OF THE SERVOCONTROL MEANS COMPRISING TWO RADAR TRANSMITTER-RECEIVER CHANNELS HAVING SAID ANTENNA AXIS IN COMMON AND PROVIDING RESPECTIVELY DIFFERENT SIGNAL FREQUENCIES FROM SAID ANTENNA; MEANS FOR PROVIDING ERROR VOLTAGES INDICATIVE OF THE DEPARTURE OF THE CONTROLLED VARIABLE FROM A REFERENCE VALUE; DISCRIMINATOR MEANS HAVING INPUTS CONNECTED TO SAID TRANSMITTER-RECEIVER CHANNELS FOR SELECTING THE ONE ERROR VOLTAGE HAVING THE SMALLER AMPLITUDE; AND CIRCUIT MEANS CONNECTING SAID DISCRIMINATOR MEANS TO SAID SERVOCONTROL MEANS FOR APPLYING SAID ONE ERROR VOLTAGE TO THE FOLLOW-UP CONTROL OF SAID ANTENNA AXIS.
Claim 4
