Abstract: A method for detecting and locating a carbon dioxide leak in a submarine environment includes operating autonomous underwater vehicles (AUVs) in the submarine environment, where the operating includes obtaining, with each AUV of the AUVs, measurements of an attribute indicative of carbon dioxide, communicating, while operating the AUVs, the measurements from the each AUV to other AUVs of the AUVs, mapping, while operating the autonomous AUVs, carbon dioxide concentration in the submarine environment, and guiding the AUVs toward a highest concentration of the carbon dioxide concentration based on the mapping.

Abstract: A force application system for placement on and removal from an actuable latch with a robotic arm includes a driving pad configured for attachment to the actuable latch, a force application mechanism configured to increase an input force to an amplified output force that is applied by the force application mechanism to the driving pad, and a frame for engagement by the robotic arm.

Abstract: A portable inspecting device includes PZT transducers and performs active sensing to measure the characteristics of bolted connections. The PZT transducers are mounted on opposing ends of spring-loaded rods and can be moved apart to accommodate a structure for testing. The springs cause the PZT transducers to push against opposing parts of the structure in a stable but temporary fashion. The device can be physically moved to inspect the status and health of multiple different bolted connections.
