Claims

1. A METHOD OF TRANSMITTING SIGNAL INFORMATION FROM AN ELECTRICAL TRANSDUCER, LOCATED WITHIN AN ASSEMBLY HAVING COMPLETE ENCLOSING MEANS, TO AN EXTERIOR OBSERVATION STATION, WITHOUT DIRECT ELECTRICAL CONNECTION BETWEEN SAID TRANSDUCER AND SAID OBSERVATION STATION, WHICH METHOD COMPRISES THE STEPS OF:

(I) GENERATING A FIRST VARIABLE FREQUENCY OSCILLATORY SIGNAL, EXTERIORLY OF SAID ASSEMBLY, (II) UTILIZING SAID FIRST VARIABLE FREQUENCY OSCILLATORY SIGNAL TO PRODUCE A FIRST MGNETIC FLUX EXTERIORLY OF SAID ASSEMBLY AND ADJACENT THEREOF, (III) INTERCEPTING SAID FIRST MAGNETIC FLUX AT A FIRST ZONE INTERIORLY OF SAID ASSEMBLY, (IV) GENERATING A SECOND VARIABLE FREQUENCY OSCILLATORY SIGNAL WITHIN SAID ASSEMBLY BY MEANS OF THE INTERCEPTION OF SAID FIRST FLUX, (V) PRODUCING A VARIABLE FREQUENCY OSCILLATORY THIRD SIGNAL WITHIN SAID ASSEMBLY AS A FUNCTION OF SAID SECOND VARIABLE FREQUENCY OSCILLATORY SIGNAL AND SAID SIGNAL INFORMATION, SAID THIRD SIGNAL HAVING AN AMPLITUDE INDICATIVE OF THE RELATIONSHIP OF SAID SECOND SIGNAL AND SAID SIGNAL INFORMATION, (VI) PRODUCING A SECOND ALTERNATING MAGNETIC FLUX, BY MEANS OF SAID FIRST COMPARISON SIGNAL, INTERIORLY OF SAID ASSEMBLY AT A SECOND ZONE THEREON, (VII) INTERCEPTING SAID SECOND ALTERNATING MAGNETIC FLUX, EXTERIORLY OF SAID ASSEMBLY, AT SAID SECOND ZONE, (VIII) GENERATING A DETECTING SIGNAL BY MEANS OF SAID INTERCEPTION OF SAID SECOND ALTERNATING MAGNETIC FLUX, AND ADJUSTING THE FREQUENCY OF SAID FIRST VARIABLE FREQUENCY OSCILLATORY SIGNAL TO ESTABLISH A BALANCE FREQUENCY, (IX) UTILIZING SAID BALANCE FREQUENCY TO INDICATE THE VALUE OF SAID SIGNAL INFORMATION.
