Signal multiplier where one signal to be multiplied causes a member to deform

Claim 1

APPARATUS FOR MULTIPLYING A FIRST ELECTRICAL SIGNAL BY A SECOND ELECTRICAL SIGNAL COMPRISING A DEFORMABLE MEMBER; MEANS ACTUATED BY SAID FIRST SIGNAL TO DEFORM SAID MEMBER BY AN AMOUNT REPRESENTATIVE OF SAID FIRST SIGNAL COMPRISING MEANS ESTABLISHING A MAGNETIC FIELD, A COIL POSITIONED FOR MOVEMENT WITHIN SAID MAGNETIC FIELD, A COIL COIL BEING ADAPTED TO HAVE SAID FIRST SIGNAL APPLIED THERETO, AND MEANS CONNECTING SAID COIL TO SAID MEMBER SO THAT MOVEMENT OF SAID COIL IN SAID FIELD RESPONSIVE TO CURRENT THERETHROUGH DEFORMS SAID MEMBER; FIRST AND SECOND STRAIN GAUGES ATTACHED TO SAID MEMBER SO THAT THE ELECTRICAL IMPEDANCE PEDANCE OF ONE IS INCREASED AND THE ELECTRICAL IMPEDANCE OF THE OTHER IS DECREASED WHEN SAID MEMBER IS DEFORMED; AN ELECTRICAL BRIDGE NETWORK HAVING SAID STRAIN GAUGES CONNECTED THEREIN SO THAT THE OUTPUT SIGNAL FROM SAID BRIDGE NETWORK VARIES AS A FUNCTION OF CHANGES IMPEDANCE OF SAID GAUGES IN RESPONSE TO SAID MEMBER BEING DEFORMED; AND MEANS TO APPLY SAID SECOND SIGNAL ACROSS SAID BRIDGE NETWORK TO ENERGIZE SAME.
