Coaxial connectors include a connector body that includes a first connector body opening for receiving a coaxial cable. A tubular inner contact post that is at least partly within the connector body is provided. A sliding compression element is also provided that is configured to impart a generally circumferential compressive force to secure one or more elements of the coaxial cable between the sliding compression element and the connector body when an axially directed force that is directed away from the connector body is applied to the coaxial cable.

A coupling for connecting conduits is provided, including a first element having a first mating member and a second element having a second mating member. The first element and the second element selectively securingly engaging each other. The first mating member and the second mating member sealingly connecting the conduits. An inner member is disposed at least partially within the second element, and a compression member is disposed about the first element, the compression member cooperating with the inner member for forcing the first element and the second element together, wherein the first element, the second element, and the inner member cooperate to resist pulling apart of the coupling.

摘要:
An unmanned system for investigating underwater regions utilizes an unmanned mothership and a plurality of unmanned underwater vehicles (UUVs). The mothership transports the UUVs to and from the vicinity of an underwater region, releases the UUVs into the water, and facilitates recovery of the UUVs from the water. Each UUV can traverse an underwater region, generate sonar and image data associated with the underwater region, and transmit the sonar and image data through the water for receipt and re-transmission by the mothership. A docking system mounted partially onboard the mothership and partially onboard each UUV couples each UUV to the mothership and selectively releases each UUV into the underwater region. A guidance system mounted partially onboard the mothership and partially onboard each UUV guides each UUV back to the docking system from positions in the water. The mothership and UUVs can also be equipped with a non-contact electrical energy transfer system so that each UUV can return to the mothership and re-charge onboard batteries while underwater.
