    摘要: A switchable magnetic apparatus has a first layer having one or more first-layer magnets, a second layer on a rear side of the first layer and having one or more second-layer magnets, and a third layer on a rear side of the second layer. The first and second layers are movable relative to each other between an ON position and an OFF position for switching the apparatus between an ON state and an OFF state. The third layer has one or more third-layer magnets for applying a first force to the one or more second-layer magnets when the second layer is at a position intermediate the ON and OFF positions, and the first force is at a direction opposite to a second force applied to the one or more second-layer magnets by the first-layer magnets when the second layer is at the position intermediate the ON and OFF positions.

    摘要: A switchable magnet device comprising at least one magnet package which can be moved between an interaction position and a release position, wherein the magnet device is configured such that the at least one magnet package, when moving between the interaction position and the release position, at least in portions, performs a pivot movement about a pivot axis. An actuation device is also provided, which can be coupled to the at least one magnet package to move the at least one magnet package between the interaction position and the release position. In order to easily lift the magnet from the formwork support in a small working space, the magnet device is configured such that the at least one actuation device, at least in portions and at least temporarily during the pivot movement of the at least one magnet package, performs a linear movement in a linear movement direction.

    摘要: Magnet array structure includes a first linear magnet array and a second linear magnet array having a first and a second arrangement of magnets, respectively, in which the first and the second arrangement of magnets are repeated along respective lengths of the first and second linear magnet array. The first and second arrangement of magnets include respective individual first and second magnet elements arranged along the respective length of the first and second linear magnet array so that no net magnetic forces parallel to the length of the first and second linear magnet array result on the first and second arrangement of magnets, respectively. The first arrangement of magnets is offset from the second arrangement of magnets so that the first arrangement of magnets and the second arrangement of magnets partially overlap.

    摘要: An electrical device, such as a camera controller includes a connector having a first magnetic element and a first cam surface. An electrical housing includes a housing panel having an outer surface configured to receive the connector. A target element is disposed within the electrical housing. The target element includes a second magnetic element. The outer surface includes a second cam surface configured to engage the first cam surface and translate a rotation of the connector into an axial displacement of the connector. In one aspect, a target positioning member is configured to position the target element into the first position when the connector is removed from the outer surface. The targeting positioning member is further configured to position the target element into the second position when the first cam surface engages the second cam surface.

    摘要: The present disclosure relates to a mounting jig for manufacturing a tiling display device and a manufacturing method of a tiling display device using the same. A mounting jig for manufacturing a tiling display device according to an embodiment of the present disclosure includes: a supporting member; a plurality of jig magnets fixed to the supporting member; a hinge structure configured to rotate the plurality of jig magnets; and a guard rail rotating in response to rotation of the plurality of jig magnets and reducing damage caused during detachment or attachment. Therefore, when the mounting jig is attached to a display device, a safety distance can be secured by the guard rail disposed between the display device and the jig magnets and the mounting jig can be slowly attached to the display device without giving an impact to the display device.
