Claim 1
Independent Claim
124 words
APPARATUS FOR COMPUTING THE EFFECTIVE "CENTER OF GRAVITY" OF A PLURALITY OF MEASURES HAVING, IN COMBINATION, AT LEAST THREE ELECTRICAL CONDUCTANCE ELEMENTS THE RESPECTIVE CONDUCTANCE VALUES OF WHICH ARE ADJUSTED IN ACCORDANCE WITH THREE SEPARATE MEASURES, AN ELECTRIC CIRCUIT CONNECTING THE ELEMENTS AS A T NETWORK WITH TWO OF THE ELEMENTS IN SERIES AND A TERMINAL OF THE THIRD ELEMENT COMMON WITH THE SERIES-CONNECTING TERMINAL OF THE SAID TWO ELEMENTS, MEANS FOR CONNECTING A CONSTANT VOLTAGE SOURCE IN SERIES WITH THE SAIDTWO ELEMENTS, MEANS FOR CONNECTING THE OTHER TERMINAL OF THE SAID THIRD ELEMENT TO ONE SIDE OF THE SOURCE, AND MEANS FOR INDICATING THE VOLTAGE DEVELOPED AT THE SAID COMMON TERMINAL TO DETERMINE ONE OF THE COORDINATES OF THE SAID CENTER OF GRAVITY.
