Abstract: Various embodiments include an adapter between two connectors and a coaxial coupling or a coaxial nipple. The two connectors are any combination of a separate coupling and a separate nipple. The adapter may include: a body with two cylindrical openings; a first element that fits in the first opening with connections for a first of the two connectors and the coaxial coupling or nipple; and a second element that fits in the second cylindrical opening, and a third connection for the other connector. The first element slides and rotates in the body and has a central axis eccentric to a central axis of the cylindrical first element part. The second element slides and rotates in the body. The central axis of the third connection is eccentric to a central axis of the cylindrical second element part.

Abstract: An electronic device is configured to, during transportation to a destination, determine its position and transmit position data to a remote computer. To lower power consumption and enable arrival detection based on the position, the electronic device obtains, based on a first position determined at a first time point, an estimated remaining transportation time to the destination, and determines, based on the estimated remaining transportation time, a second time point for determining a second position. The electronic device may then determine the second position at the second time point. Alternatively, to account for unscheduled delays, the electronic device may determine a third time point by selectively modifying the second time point based on sensor data from a movement sensing system on the electronic device and determine the second position at the third time point.

Abstract: A tracker device includes a positioning system, a communication system, and a movement sensing system. The tracker device is configured to utilize the movement sensing system to reduce power consumption during waterborne transport. The tracker device intermittently operates its positioning system to determine a geographic position of the tracker device, and intermittently operates the communication system to transmit the geographic position to a remote computer. The tracker device further detects, based on at least one signal from the movement sensing system, that the tracker device is in transit on a waterborne vessel, and disables the communication system when the tracker device is detected to be in transit on the waterborne vessel.

Abstract: An electronic device includes a camera assembly configured to capture an image and to process the image to create an image file. The electronic device further includes a communications interface, and a processor configured to generate digital ledger data comprising a smart contract providing rights to use or access the image based on a condition being satisfied, and image rights management information. The processor is further configured to transmit the digital ledger data using the communications interface, to a digital ledger network, and embed a pointer or link as a portion of data included within the image file. The pointer or link provides a location to access the digital ledger data.

Abstract: A locking mechanism for a quick connect coupling having a locking sleeve (100) is disclosed. The locking sleeve is axially displaceable for locking the quick connect coupling in a locked position (110) and for unlocking the quick connect coupling in an unlocked position (120). The locking mechanism comprises a safety ring (200), the safety ring (200) is axially displaceable for engaging the locking sleeve (100) and the safety ring (200) being partly inside or partly outside the locking sleeve (100). The safety ring being positionable in three different axial positions, a first axial position (210) for allowing the locking sleeve (100) to be in the unlocked position (120), a second axial position (220) for allowing the safety ring (200) to rotate, and a third axial position (230) for allowing the locking sleeve(100) to be in the locked position (110). The locking mechanism comprises a spring (300), the spring acting between the locking sleeve (100) and the safety ring (200).

Abstract: A nipple for a coaxial coupling is disclosed. The nipple comprises a housing (40), and a nipple tube (30) arranged in the housing (40). The nipple comprises a first passage (42) between the housing (40) and the nipple tube (30), and the nipple tube (30) comprising a second passage (32) within the nipple tube (30). A relief valve (20) is slideably arranged in the nipple tube (30). The nipple comprises sealing means (24, 26) for sealing between the nipple tube (30) and the relief valve (20).
