A first magnet is movable along a side wall of the plate member and is rotatable about a first rotation axis oriented along the length of the first magnet and about a second rotation axis oriented along a thickness direction of the plate member. The plurality of accommodation portions are disposed along one or more side walls of the plate member, and a first accommodation portion include a first end portion. A width of the first end portion is equal to or greater than the width of the first magnet, the width of the first end portion is less than the length of the first magnet, and a width of an accommodation space in the first accommodation portion is greater than the width of the first end portion.

In an embodiment, a gaming screen comprising a first panel having a first edge, a first magnet rotatably mounted at the first edge, a second panel having a second edge, and a second magnet rotatably mounted at the second edge. The first and second magnets are arranged to attract to each other and form a hinge between the first panel and the second panel. The panel may be folded into a compact state for carrying or storage.

A magnetic latching mechanism including a servo-motor configured to rotate an axle; a latching rotor attached to the axle and configured to rotate; and a pair of latching permanent magnets attached to the latching rotor. A north pole of a permanent magnet and a south pole of another permanent magnet of the pair are facing along a same direction.

An identification (ID) number setting method for a modular device that comprises a master building element and a plurality of slave building elements that are connected to the master building element, includes: disconnecting the slave building elements from the master building element; setting ID numbers of all of the slave building elements to be a preset ID number; and assigning new ID numbers to slave building elements of N tiers that are connected to one output interface of the master building element in an order from first tier to Nth tier, wherein the slave building elements of the first tier are slave building elements that are directly connected to the output interface, the slave building elements of the Nth tier are slave building elements that are indirectly connected to the output interface through slave building elements of a (N−1)th tier, N is a natural number greater than 1.

A family hand puppet. A substantially solid body is provided in the shape of a human hand, the body having a main portion and a plurality of separate fingers extending therefrom, each finger having a distal end. A set of separate attachments is also provided, and a fastening mechanism such as hook and loop fasteners or adhesive tape releasably connects the set of separate attachments to corresponding distal ends of the fingers. In another embodiment, the puppet has a hollow body, forming a glove for articulation by a human hand inserted therein.

A Lynchpin structure may be combined with one or more additional Lynchpin structures to form a compound Lynchpin propulsion structure. Each Lynchpin structure may include six pentangular areas, and one or more of the pentangular areas may include a propulsion device. The propulsion may be used to propel the compound Lynchpin propulsion structure through or over various media, such as through air, across ground, on or underwater, or through or over other media. The propulsion may include avionic propulsion, ground propulsion, hydrodynamic propulsion, or other types of propulsion. A single type of propulsion device may be used within one or more of the pentangular areas, or diverse types of propulsion may be used to provide various navigational performance or multi-mode operation. Each propulsion device may also include a device to direct the propulsion, such as a single or multi-axis gimble or adjustable aerodynamic control surface.

A magnetic 3D terrain gaming tile comprising: a slab having a top surface and a bottom surface; a plurality of edge walls extending away from the bottom surface of the slab so as to define a bottom recess; a plurality of pockets disposed in the bottom recess; and a plurality of spherical magnets disposed in the plurality of pockets; wherein one spherical magnet is disposed in each of the plurality of pockets, with the spherical magnet being rotatably captured within the pocket.

A building system includes a plurality of building tiles and/or connecters that are magnetically and releasably connectable to one another. The magnetic building tiles are comprised of a frame and a panel. The tile frame, by one approach, is comprised of two connectable frame portions having magnets embedded therein. The first frame element and the second frame element are connectable to one another through a snap, clip, or another similar connection mechanism. The first and second frame elements are connectable around or into the tile panel, which is removable from the magnetic building tile. The tile panel or the tile frame has a channel into which the other of the tile panel or tile frame extends to secure the two pieces together. In another approach, the tile frame is a single element and the tile panel may snap or attach thereto, such as, for example, through fasteners or friction.

A geometric art toy includes first toy members and second toy members which are interconnected and magnetized in particular configurations such that the geometric art toy can be alternately and stably positioned in different configurations.
