Abstract: Networking systems and methods of assembly are described that provide a modular system that includes a main networking box and a detachable module. The main networking box and the detachable module are configured to be connected to each other on a datacenter rack via board-to-board connectors to provide the desired connections to the network, but can also be unlocked and detached from each other, such as to allow the main networking box to be replaced. In this way, the main networking box can be replaced in the field to provide a repair, or the detachable module can be replaced to provide a different connection type, without requiring the other component and/or its connections to be disturbed.

Abstract: A bearing assembly comprises clearance-tree outer and inner ball raceways which define outer and inner rings supporting the inner and outer spherical and eccentric annular spaces, and eccentric outer and inner ball raceways respectively arranged in the outer and annular spaces, and elements for tilting by sliding the eccentric outer and inner ball raceways, to compensate run-outs. The invention is applicable to ball-, roller- or needle-antifriction bearings.

Abstract: A roller skate which includes specially shaped front and back wheels which allow the skate to operate on flat ground and over pipes or rails. The skater is able to perform stunts and maneuvers involving pipes or rails of different diameters due to the front and back wheel geometry. The hourglass-shaped cross-section that is created by the configuration of the front and back wheels centers the pipe or rail that is being skated on under the center of balance of each skate. The two front and two back wheels each have a half hourglass shape, and are able to spin independently of each other.
