A system for imaging a combustion turbine engine airfoil includes a camera and a positioner. A positioning structure includes a locking member fixed on the outer casing, and a support member for immobilizing the locking member with respect to the outer casing in such a manner that the locking member extends upwardly into the outer casing to prevent movement of the tray with respect to the outer casing. After learning this information, the node may verify a status of each of the paths using the first connectivity protocol. Additionally, techniques are disclosed to increase the deposition rate of the first secondary metal between primary metal features in order to prevent voiding and thus enhance structural support of the primary metal during machining. A flexible element is coupled between the deflectable distal tip and the carriage. Accordingly, a hybrid vehicle that does not require a torque limiter is provided.
