Abstract: A method for providing secure remote access by a controller is described. The method includes sending one or more endpoint requests. The method also includes receiving authentication service endpoint information and connection service endpoint information. The method further includes requesting authentication based on the authentication service endpoint information. Requesting authentication includes requesting license validation. The method also includes sending one or more registration messages based on the connection service endpoint information. The method further includes receiving a session request. The method additionally includes determining controller candidate link information. The method also includes sending the controller candidate link information. The method further includes receiving an automation message based on the controller candidate link information.

Abstract: A system for determining the direction of an underwater discrete source of acoustic vibrations by sensing acoustic wavefronts produced thereby, which system comprises a neutrally buoyant semirigid underwater platform which may be made of a water inflated soft walled material and having mounted thereon an array of omnidirectional hydrophones arranged in a predetermined geometric pattern. Circuit means are connected to the hydrophones and an array steering means is associated with the circuit means to allow determination of the time relationship of the signals obtained from the hydrophones.

Abstract: A sonobuoy casing which comprises a split enclosure for a hydrophone, hinged at its base end. Upon deployment, the enclosure falls away, releasing the hydrophone to drop to its prescribed depth. A release mechanism which pushes the hydrophone out of its casing is thus dispensed with.
