An acoustic method and apparatus for an acoustic system use a transceiver module, which can transmit to a transmit acoustic element of a transmit sonar array and receive from a receive acoustic element of a receive sonar array in accordance with a common transmit/receive control signal.

Method and apparatus for acoustic system having a transceiver module

A corrosion resistant connection system including a base structure, a threaded orifice in the base structure, a seal about the threaded orifice and a threaded stud with a distal end, a proximal end, and an intermediate shoulder defining a sealing surface opposing a support surface. The distal end of the threaded stud is received in the orifice of the base structure driving the sealing surface of the shoulder to engage the seal to prevent corrosion of the threaded orifice, while maintaining electrical continuity. A terminal is disposed about the proximal end of the threaded stud seated on the support surface of the shoulder. A threaded nut is disposed about the proximal end of the stud engaging the terminal.
