Claim 1
Independent Claim
227 words
COMPUTING APPARATUS ADAPTED TO RECEIVE AN INPUT INCLUDING ONE OR MORE VARIABLE SIGNALS AND TO PRODUCE AN OUTPUT REPRESENTING A MATHEMATICAL OPERATION ON SAID INPUT; SAID APPARATUS COMPRISING: A SUPPORT STRUCTURE, A BALANCEABLE MEMBER MOUNTED FOR MOVEMENT WITH RESPECT TO SAID SUPPORT STRUTURE, FIRST SIGNAL-RESPONSIVE MEANS FOR PRODUCING A FIRST FORCE ACTING ON SAID BALANCEABLE MEMBER IN ONE DIRECTION; SECOND SIGNAL-RESPONSIVE MEANS FOR PRODUCING A SECOND FORCE ACTING ON SAID BALANCEABLE MEMBER IN A DIRECTION TRANSVERSE TO SAID ONE DIRECTION; MOVEMENT CONTROLLING MEANS CONNECTED TO SAID BALANCEABLE MEMBER TO DETERMINE THE DIRECTION OF MOVEMENT OF SAID MEMBER IN RESPONSE TO CHANGES IN EITHER OF SAID FIRST OR SECOND FORCES, SAID MOVEMENT CONTROLLING MEANS COMPRISING A PIVOTALLY MOUNTED ELEMENT LOCATED ADJACENT SAID BALANCEABLE MEMBER, A FLEXURE SECURED TO SAID ELEMENT WITH ONE END EXTENDING TOWARDS SAID BALANCEABLE MEMBER, AND CONNECTION MEANS FOR SECURING SAID FLEXURE END TO SAID BALANCEABLE MEMBER, SIGNAL-RESPONSIVE ADJUSTMENT MEANS COUPLED TO SAID CONTROLLING MEANS TO VARY THE POSITIONING OF SAID ELEMENT ABOUT ITS PIVOT MOUNTING AND ALTER THE ANGULAR RELATIONSHIP BETWEEN SAID FLEXURE AND SAID BALANCEABLE MEMBER; SENSING MEANS ARRANGED TO DETECT CHANGES IN POSITION OF SAID BALANCEABLE MEMBER AND TO PRODUCE A REBALANCE SIGNAL IN RESPONSE TO SUCH CHANGES; AND SIGNAL TRANSMISSION MEANS FOR FEEDING SAID REBALANCE SIGNAL TO ONE OF SAID SIGNAL-RESPONSIVE MEANS TO MAINTAIN THE FORCES ON SAID MEMBER IN BALANCE.
