Solid state temperature measuring device

Claim 1

A LINEAR SOLID STATE TEMPERATURE DETECTOR COMPRISING A TEMPERATURE RESPONSIVE BRIDGE HAVING: (A) A FIRST PAIR OF DIAGONALLY OPPOSED INPUT TERMINALS FOR CONNECTION TO A SOURCE OF POTENTIAL; (B) A SECOND PAIR OF DIAGONALLY OPPOSED OUTPUT TERMINALS PROVIDING MEANS FOR DERIVING AN OUTPUT CURRENT INDICATIVE OF BRIDGE UNBALANCE; (C) CURRENT MEASURING MEANS CONNECTED TO SAID OUTPUT TERMINALS; (D) A FIRST BRIDGE ARM CONNECTED BETWEEN ONE OF SAID PAIR OF INPUT TERMINALS AND ONE OF SAID OUTPUT TERMINALS; (E) A SECOND BRIDGE ARM CONNECTED BETWEEN THE OTHER OF SAID INPUT TERMINAL AND SAID ONE OF SAID OUTPUT TERMINALS; (F) A THIRD BRIDGE ARM CONNECTED BETWEEN THE OTHER SAID OUTPUT TERMINAL AND SAID ONE OF SAID INPUT TERMINAL; (G) A FOURTH BRIDGE ARM CONNECTED BETWEEN THE SAID OTHER OUTPUT TERMINAL AND THE SAID OTHER INPUT TERMINAL; WHEREIN EACH OF SAID BRIDGE ARMS ARE COMPOSED OF A LIKE PLURALITY OF LIKE SEMICONDUCTOR JUNCTIONS, SIMILARLY ORIENTED RELATIVE TO SAID FIRST PAIR OF OUTPUT TERMINMALS, AND EACH OF SAID ARMS BEING CHARACTERIZED BY SUBSTANTIALLY INDENTICAL TEMPERATURE VS. VOLTAGE CHARACTERISTICS, AT LEAST ONE OF SAID BRIDGE ARMS BEING POSITIONED IN THE ENVIRONMENT THE TEMPERATURE OF WHICH IS TO BE MEASURED.
