Data measuring and transmission system

Claim 1

IN A MULTICHANNEL MEASURING SYSTEM, THE COMBINATION OF A PLURALITY OF TRANSDUCERS, EACH OF SAID TRANSDUCERS INCLUDING A RESONANT CIRCUIT THE RESONANT FREQUENCY OF WHICH IS VARIED IN RESPONSE TO VARIATIONS OF A MEASURED VARIABLE, A SOURCE OF D.C. VOLTAGE, MEANS FOR SEQUENTIALLY CONNECTING SAID D.C. SOURCE ACROSS DIFFERENT ONES OF SAID RESONANT CIRCUITS, THE PERIODS DURING WHICH SAID SOURCE IS CONNECTED TO SAID RESONANT CIRCUITS BEING SEPARATED BY INTERVALS OF SUFFICIENT DURATION TO PERMIT THE DEVELOPMENT OF DAMPED OSCILLATORY TRANSIENTS ACROSS SAID RESONANT CIRCUITS DURING SAID SEPARATION INTERVALS, A COMMON OUTPUT CHANNEL, MEANS COUPLING ALL OF SAID RESONANT CIRCUITS TO SAID COMMON OUTPUT CHANNEL, AND MEANS CONNECTED TO SAID COMMON OUTPUT CHANNEL FOR MEASURING THE PERIODS OF SAID SUCCESSIVELY PRODUCED OSCILLATORY TRANSIENTS TO OBTAIN A PLURALITY OF SIGNALS CORRESPONDING TO THE VALUES OF THE MEASURED VARIABLES.
