The fastening means on the bottom face have at least one latch hook for latching into a corresponding latch opening on the front panel of the electrotechnical component, and/or the fastening means on the bottom face have at least one snap hook for snapping into a corresponding snap opening on the front panel of the electrotechnical component.

A planar transformer for power transmission, having vertical and horizontal extents, includes a circuit board having a sandwich-type structure with at least three layers to form electrical conductors. First and second layers of these layers form outer layers of the circuit board, and each additional one of these layers forms an inner layer of the circuit board. An insulation material with a minimum thickness is arranged between all of these layers, with a number of at least three mutually galvanically isolated circuits. A first circuit forms a primary circuit and each additional circuit forms an equally entitled secondary circuit, having a magnetic core assembled from two interconnected magnetic core parts. A first core part with a central part and two outer legs forms a U shape. The circuit board has two recesses, and the two outer legs of the first core part are inserted into these recesses and connected to the second core part at their ends remote from the central part. A conductor is formed on at least one of the outer layers for exactly one single circuit of the at least three circuits, and a conductor of at least one circuit of the at least three circuits is wound around a first outer leg, and conductors of at least two additional circuits of the at least three circuits are wound around the second outer leg.

A fastening device, a method of operating the fastening device, and a display panel are provided. The fastening device includes a diffuser and a limiter, wherein the limiter includes a deformation portion and a non-deformation portion disposed opposite to each other to enclose a receiving portion, and the diffuser is configured to be received in the receiving portion, so as to adjust a deformation size of the deformation portion by movement of the diffuser.

A modular data center includes a base electrical module having a casing, a controller supported by the casing, and a power distribution unit coupled to the controller. The modular data center further includes an equipment rack having a frame coupled to the base electrical module, with the frame of the equipment rack being configured to receive electronic equipment. The electronic equipment receives power from the base electrical module. The base electrical module is external to the equipment rack.

A lever assembly for coupling a computer module to a chassis includes a base lever, a locking tab, and a flexible element positioned between the base lever and the locking tab. The base lever is rotatably coupled to the computer module. The base lever is rotatable between an installed position and an opened position. The locking tab is rotatably coupled to the computer module for engaging a locking surface on the chassis when in a locked position. The locking tab is rotatable between the locked position and an unlocked position. The flexible element is configured to bias the locking tab into the locked position when the base lever is in the installed position. Rotation of the base lever to the opened position induces rotation of the locking tab to the unlocked position.

An electrical power delivery system includes a module stack, a conductive bus bar, and one or more energy storage devices. The module stack includes multiple modules stacked side by side along a stack axis. Each of the modules has a respective housing and internal electrical components within the housing. The conductive bus bar is oriented along a plane parallel to the stack axis. The bus bar is mounted along a side of the module stack and electrically connected to one or more of the modules. The one or more energy storage devices are electrically connected to the bus bar and extend from a side of the bus bar facing away from the module stack such that the bus bar is disposed between the one or more energy storage devices and the module stack.

Cable housing assemblies include frames and cable carriers slidably mounted to channels provided at edges of the frames. The cable carriers may house or support male or female connectors to the cables, which may be power or communications cables (e.g., Ethernet cables) that extend from the connectors within the cable carriers into the channels, and through voids within the frames to power sources or communications systems. The cable carriers are releasably inserted into channels at edges of the frames, and permitted to slide in either direction (e.g., up or down) to various positions within such channels, in order to make power or communications services available at such positions. When installed in association with a shelving unit, e.g., between a backerboard and shelves, the cable carriers may be used to provide power or communications services available to such shelves provided at any height within the shelving unit.

A modular wireless communications system (edge device, etc.) that includes a base unit having a base unit processor and one or more additional units that each include a processor, in which the base unit processor is configured with processor-executable software instructions to determine whether the base unit has been combined with the one or more additional units to create a combined unit and/or whether one or more of the additional units have been detached from the combined unit. The processor may automatically perform an edge reconfiguration interrogation and enumeration (ERIE) operation in response to determining that the base unit has been combined with the one or more additional units to create the combined unit or in response to determining that one or more of the additional units have been detached from the combined unit.

An additive manufactured apparatus includes an assembly of additive manufactured component voxels, each additive manufactured component voxel exhibiting a corresponding functionality. Each additive manufactured component voxel includes a base layer; an outer layer, an interior space of the component voxel being defined in a volume adjacent to the base layer and the outer layer; and a component structure associated with the functionality of the component voxel. The component structure is one or more of (i) disposed in the interior space of the component voxel and (ii) embedded in the base layer. A method for designing an apparatus to be fabricated by additive manufacturing includes defining an arrangement of component voxels based on the geometric mesh and based on a specified functionality of the apparatus, and generating machine-readable instructions for manufacturing of the arrangement of component voxels.

A modular arrangement is provided for housing electronic equipment and associated cooling structure in a data center environment. The modular units provide cooling air on an as-needed basis to individual pieces of equipment by way of individual plenums and associated valves. The units can be interconnected by vertical stacking, in side-to-side arrangements, and back-to-back arrangements. A number of units can be interconnected to form a cell. The cells can be interconnected to form larger units. In this manner, data centers can be configured in any desired arrangement without requiring complicated cooling design.
