Abstract: A coupling for interconnecting a first pipe element and a second pipe element. The coupling comprises a first coupling member on the first pipe element, and a second coupling member on the second pipe element. The second coupling member is dimensioned to receive therein the first coupling member. The coupling also includes a retainer element having threads to engage the first coupling member to retain the first and second coupling members in a coupled state. The retainer element includes a lock feature to prevent inadvertent loosening rotation.

Abstract: A coupling for interconnecting sections of pipe. The coupling includes a first pipe element having a first coupling member in the form of a female socket, and a second pipe element having a second coupling member in the form of a male plug. The socket of the first pipe element is dimensioned to receive therein the plug of the second pipe element. The coupling also includes a seal interface to prevent passage of air or fluids through an annular gap between the socket of the first coupling member and the plug of the second coupling member. The seal interface includes a sealing element and a sealing element retainer. The sealing element retainer is positioned internally of the coupling, within a cylindrical cavity of the socket.

Abstract: A method of recognizing at least one avionics system command from a voice command includes receiving a plurality of voice command definitions, each voice command definition identifying at least one avionics system command and identifying at least one voice command template that is mapped to the at least one avionics system command; receiving the voice command as raw speech; generating recognized speech by converting the raw speech into text; determining a voice command template that corresponds to the recognized speech; selecting a voice command definition, from among the plurality of voice command definitions, that identifies the determined voice command template; determining, as the at least one recognized avionics system command, the at least one avionics system command identified by the selected voice command definition; and providing the at least one recognized avionics system command to a avionics system for execution.
