Claim Text:
1. A path length control driver of a ring laser gyroscope comprising: a first piezoelectric assembly, wherein the first piezoelectric element assembly includes a first piezoelectric element, a second piezoelectric element, and a first electrode electrically coupled to a positive polarity side of the first piezoelectric element and the second piezoelectric element; a second piezoelectric assembly, wherein the second piezoelectric assembly includes a third piezoelectric element, a fourth piezoelectric element, and a second electrode electrically coupled to a positive polarity side of the third piezoelectric element and the fourth piezoelectric element; a baseplate positioned between the first piezoelectric assembly and the second piezoelectric assembly, the baseplate including a pin extending through the first piezoelectric assembly; and a flexible coupling assembly that electrically couples the first electrode to a first wire harness connection point, electrically couples the second electrode to a second wire harness connection point, and electrically couples the pin to a third wire harness connection point; wherein the flexible coupling assembly is bonded to a negative polarity side of the first piezoelectric element of the first piezoelectric assembly by a semi-rigid conductive adhesive that electrically couples the negative polarity side of the first piezoelectric element to the pin.
