Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
222 words
A SYSTEM FOR DETECTING TIME SYNCHRONISM BETWEEN A PLURALITY OF SERIAL PULSE SIGNALS WHEN SAID PULSES ARE SPACED BY PREDETERMINED TIME PERIODS T COMPRISING: A SOURCE OF SERIAL PULSES, FIRST DELAY MEANS FOR RECEIVING PULSES AND PRODUCING OUTPUT PULSES REPRESENTATIVE OF SAID RECEIVED PULSES DELAYED BY SAID TIME PERIOD T, MEANS FOR SUPPLYING PULSES FROM SAID SOURCE TO SAID FIRST DELAY MEANS, FIRST COINCIDENCE DETECTING MEANS FOR DETECTING COINCIDENCE BETWEEN PULSES FROM SAID SOURCE AND OUTPUT PULSES FROM SAID FIRST DELAY MEANS AND RESPONSIVE TO SUCH COINCIDENCE FOR PRODUCING A FIRST COINCIDENCE OUTPUT SIGNAL, FIRST INCREMENTAL DELAY MEANS FOR DELAYING SAID FIRST COINCIDENCE OUTPUT BY A TIME PERIOD T AND SUPPLYING SAID DELAYED COINCIDENCE OUTPUT TO SAID FIRST DELAY MEANS, SAID TIME PERIOD T BEING SUBSTANTIALLY SHORTER THAN SAID PERIOD T, SECOND INCREMENTAL DELAY MEANS FOR DELAYING OUTPUT PULSES FROM SAID FIRST DELAY MEANS BY SAID TIME PERIOD T, THIRD INCREMENTAL DELAY MEANS FOR DELAYING PULSES FROM SAID SOURCE OF REGULAR RECEIVING PULSES BY SAID PERIOD T, SECOND COINCIDENCE DETECTING MEANS FOR DETECTING COINCIDENCE BETWEEN PULSES FROM SAID SECOND AND THIRD INCREMENTAL DELAY MEANS AND OUTPUT PULSES FROM SAID FIRST DELAY MEANS AND RESPONSIVE TO COINCIDENCE FOR PRODUCING A SECOND COINCIDENCE OUTPUT PULSE, SAID SECOND COINCIDENCE OUTPUT BEING INDICATIVE OF EQUAL TIME SPACING T BETWEEN THE LAST THREE PULSES FROM SAID SOURCE.

Claim 3
Dependent Claim
33 words
THE SYSTEM OF CLAIM 1 WHEREIN: SAID SOURCE OF SERIAL PULSES IS A BRACKET DECODER OF AN IFF RADAR SYSTEM, AND SAID TIME PERIOD T EQUALS THE REPETITION TIME OF SAID RADAR SYSTEM.
