An aircraft rotational joint comprises a slip-ring device arranged for electrical energy transmission through the rotational joint. The slip-ring device comprises a first member attached to a first part of the rotational joint. The first member has a plurality of arcuate metallic ring segments and all these ring segments are isolated from each other and are spaced apart from each other. Further, the slip-ring device comprises a second member which is rotatable relative to the first member about a common rotational axis. The second member is attached to a second part of the joint and has a plurality of contact elements, each of which are arranged for electrically connecting one, preferably only one, of the ring segments.

The invention concerns a rack module for forming a support column, such as a rack, by stacking at least two rack modules, the rack module having at least one site for receiving a device for administering a medical product, this site comprising at least one plug for electric current supply to the administering device and for data transfer. It is also provided with an inlet connector and an outlet connector for connecting two successive modules to each other, power lines and data transfer lines connecting the inlet connector with the plug of the sites on the one hand side and with the outlet connector on the other hand side. In order to improve the connection between the rack modules in order to make its use easier, it is suggested according to the invention that the inlet connector or the outlet connector is movable between a stocking position and a connected position, the movable connector being called mobile connector and the other connector being called second connector, wherein, when a second module is placed over or under the module, the mobile connector in the connected position is in connection with the second connector of a second module placed over or under the module. This allows to stock in a safe position one of the connectors so that during the stocking and the handling of the module there is no risk for it to be damaged.

The present disclosure provides an attachable external display screen for use on electronic devices. The display screen may be removably mounted onto a surface of an electronic device to provide the user with an additional display screen. The attachable external display screen is lightweight and has a more even weight distribution than other attachable display accessories due to the placement of the mother control board in the mount. The attachable external display screen also provides for a wireless connection to the electronic device.

Disclosed is a high voltage electrical swivel including: a first part and a second part, which are mobile relative to each other and form a closed internal chamber, each of the two parts including at least one electrical connector; and at least one electrical track electrically linked to a connector of one of the two parts and at least one brush assembly electrically linked to a connector of the other of the two parts, the at least one brush assembly cooperating with the at least one electrical track to establish an electrical contact, the at least one electrical track and the at least one brush assembly being housed in the closed internal chamber. The closed internal chamber is filled with a dielectric insulating gas having a dielectric strength greater than that of the air surrounding the electrical swivel.

A connector assembly that includes an outer shell and a first communication connector. The first communication connector and/or the outer shell is/are movable about one or more degrees of freedom. The first communication connector is configured to form a first electrical or optical connection with an external communication connector. Optionally, the connector assembly includes a second communication connector. The first communication connector may be connected to a cable or the optional second communication connector by a flexible substrate positioned inside the outer shell. The first communication connector may be implemented as a fiber optic connector optically connected to either a fiber optic cable or the second communication connector, which may also be implemented as a fiber optic connector.

A push pull coupler for hydraulic or other line that pivots about two axes in response to a predetermined tensile force exerted by a line connected to an adapter of the coupler, so that a face of the adapter is normal to the predetermined tensile force. A tensile force greater than the predetermined tensile force causes the disconnection of the line from the adapter. In one embodiment, a second push-pull coupler pivots around a third axis different from the first and second axes, responsive to a second predetermined tensile force that doesn't have to be parallel to the first predetermined tensile force. The faces of the couplers' adapters therefore become normal to the respective tensile forces exerted on them prior to disconnection of the lines.

The description relates to hinged devices, such as hinged computing devices. One example can include a first portion and a second portion. The example can also include a communication member spanning between the first and second portions and defining first and second parallel hinge pins. The first hinge pin can include a first cam follower that is received in a first multi-lobe cam of the first portion that forces the first portion away from the first hinge pin when the first and second portions are oriented at non-parallel orientations and allows the first portion to be biased toward the second hinge pin at parallel orientations.
