Amplitude range signal monitoring device

Claim 1

AN ELECTRONIC SIGNAL MONITORING DEVICE COMPRISING: (1) A FIRST REFERENCE VOLTAGE SOURCE ADAPTED TO DEVELOP A REFERENCE VOLTAGE OF A PREDETERMINED CONTROLLABLE MAGNITUDE; (2) A SECOND REFERENCE VOLTAGE SOURCE ADAPTED TO DEVELOP A REFERENCE VOLTAGE OF A PREDETERMINED CONTROLLABLE MAGNITUDE; LESS THAN THAT OF SAID FIRST SOURCE; (3) FIRST, SECOND AND THIRD ELECTRICAL SIGNAL AMPLIFYING MEANS EACH ADAPTED TO RECEIVE SIMULTANEOUSLY AN INPUT SIGNAL OF UNKNOWN MAGNITUDE, SAID FIRST AND SECOND AMPLIFYING MEANS BEING ADAPTED TO RECEIVE SAID FIRST AND SECOND REFERENCE VOLTAGES SAID FIRST AMPLIFYING MEANS BEING ADAPTED TO DEVELOP AN OUTPUT SIGNAL WHEN SAID INPUT SIGNAL HAS A MAGNITUDE GREATER THAN THE MAGNITUDE OF SAID FIRST REFERENCE VOLTAGE AND SAID SECOND AMPLIFYING MEANS BEING ADAPTED TO DEVELOP AN OUTPUT SIGNAL WHEN SAID INPUT SIGNAL HAS A MAGNITUDE GREATER THAN THE MAGNITUDE OF SAID SECOND REFERENCE VOLTAGE; (4) FIRST, SECOND AND THIRD TRIGGER CIRCUITS COUPLED TO SAID FIRST, SECOND AND THIRD AMPLIFYING MEANS RESPECTIVELY AND EACH ADAPTED TO DEVELOP A TRIGGERING PULSE WHEN THE AMPLIFYING MEANS COUPLED THERETO DEVELOPS AN OUTPUT SIGNAL OF A PREDETERMINED MAGNITUDE; (5) A FIRST BISTABLE FLIP FLOP MEANS COUPLED TO SAID FIRST TRIGGER CIRCUIT, A SECOND BISTABLE FLIP FLOP MEANS COUPLED TO SAID SECOND TRIGGER CIRCUIT AND A THIRD BISTABLE FLIP FLOP MEANS COUPLED TO THIRD TRIGGER CIRCUIT, EACH OF SAID FLIP FLOP MEANS BEING ADAPTED TO BE IN A FIRST ELECTRICAL STATE AND TO HAVE A FIRST OUTPUT SIGNAL WHEN A TRIGGERING PULSE IS SUPPLIED THERETO BY SAID TRIGGER CIRCUIT AND TO BE IN A SECOND ELECTRICAL STATE AND TO HAVE A SECOND OUTPUT SIGNAL DURING ALL OTHER CONDITIONS; (6) FIRST GATING MEANS COUPLED TO RECEIVE THE FIRST OUTPUT SIGNAL OF SAID FIRST FLIP FLOP MEANS AND THE FIRST OUTPUT SIGNAL OF SAID SECOND FLIP FLOP MEANS, SECOND GATING MEANS COUPLED TO RECEIVE THE SECOND OUTPUT SIGNAL OF SAID FIRST FLIP FLOP MEANS AND THE FIRST OUTPUT SIGNAL OF SAID SECOND FLIP FLOP MEANS AND A THIRD GATING MEANS COUPLED TO RECEIVE THE SECOND OUTPUT SIGNAL OF SAID SECOND FLIP FLOP MEANS AND THE FIRST OUTPUT SIGNAL OF SAID THIRD FLIP FLOP MEANS; AND (7) A PLURALITY OF INDICATOR MEANS EACH COUPLED TO A DIFFERENT ONE OF SAID GATING MEANS AND EACH ADAPTED TO BE OPERATIVE WHEN THE SIGNALS APPLIED TO THE CORRESPONDING GATING MEANS ARE OF A PREDETERMINED MAGNITUDE.
