Magnext
Magnext is a magnetic construction toy consisting of plastic building pieces containing embedded neodymium magnets, steel bearing balls, and a variety of additional parts which can be connected together to form anything from skeletal geometric shapes and structures to more robust and functional toys. Magnext is modeled after the original Geomag magnetic construction set, and features an expanded offering of accessories marketed specifically toward older children. Magnext is sold by MEGA Brands as the successor to the discontinued Magnetix series, and retains backward compatibility Backward compatibility (sometimes known as backwards compatibility) is a property of an operating system, product, or technology that allows for interoperability with an older legacy system, or with input designed for such a system, especially i ... with the parts. Rather than the rods of Geomag, Magnext has 'triangular' and 'square' pieces with 3 and 4 embedded magnets. The balls are 0.59 inches in ...

Geomag
Geomag is a magnetic construction toy. The original toy consisted of bars with a magnet on each end (neodymium alloy) all attached by a magnetic plug (coated with polypropylene) and nickel-coated metal spheres. Magnetic forces hold the bars and spheres together, creating the possibility for many constructions. Invented and patented by Claudio Vicentelli in May 1998, production is currently undertaken by Geomagworld SA at the production facilities in Novazzano, Switzerland. Product lines have been added to the original model (now called Geomag PRO), growing the Geomag range of construction toys. Since the introduction of the 2009/48/EC law on 20 July 2013 restricted the content of nickel in toys, Geomag has re-modelled the spheres with a bronze alloy coating, in order to comply with the new regulations. Invention In May 1998, Claudio Vicentelli, experienced in technical applications of permanent magnets and the creator of a product deposited for the magnetic circuit, and the brand ...

Construction Toy
A construction set is a set of standardized pieces that allow for the construction of a variety of different models. The pieces avoid the lead-time of manufacturing custom pieces, and of requiring special training or design time to construct complex systems. This makes them suitable for temporary structures, or for use as children's toys. One very popular brand is Lego. Categories Construction sets can be categorized according to their connection method and geometry: * Struts of variable length that are connected to any point along another strut, and at nodes. ** Tesseract connection points are initially flexible but can be made rigid with the addition of clips. * Struts of fixed but multiple lengths that are connected by nodes are good for building space frames, and often have components that allow full rotational freedom. ** D8h (*228) nodes are used for K'Nex, Tinkertoys, Playskool Pipeworks, Cleversticks and interlocking disks in general. ** D6h nodes are used for ...

Bearing (mechanical)
A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may ''prevent'' a motion by controlling the vectors of normal forces that bear on the moving parts. Most bearings facilitate the desired motion by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the loads (forces) applied to the parts. Rotary bearings hold rotating components such as shafts or axles within mechanical systems, and transfer axial and radial loads from the source of the load to the structure supporting it. The simplest form of bearing, the ''plain bearing'', consists of a shaft rotating in a hole. Lubrication is used to reduce friction. In the ''ball bearing'' and ''roller bearing'', to reduce sliding ...

Shape
A shape or figure is a graphics, graphical representation of an object or its external boundary, outline, or external Surface (mathematics), surface, as opposed to other properties such as color, Surface texture, texture, or material type. A plane shape or plane figure is constrained to lie on a ''plane (geometry), plane'', in contrast to ''solid figure, solid'' 3D shapes. A two-dimensional shape or two-dimensional figure (also: 2D shape or 2D figure) may lie on a more general curved ''surface (mathematics), surface'' (a non-Euclidean two-dimensional space). Classification of simple shapes Some simple shapes can be put into broad categories. For instance, polygons are classified according to their number of edges as triangles, quadrilaterals, pentagons, etc. Each of these is divided into smaller categories; triangles can be equilateral, isosceles, obtuse triangle, obtuse, Triangle#By internal angles, acute, Triangle, scalene, etc. while quadrilaterals can be rectangles, rho ...

MEGA Brands
Mega Brands Inc. (formerly Mega Bloks Inc. and Ritvik Holdings) is a Canadian children's toy company currently owned by Mattel. Mega Bloks, a line of construction set toys, is its most popular product. Its other brands include Mega Construx, Mega Puzzles, Board Dudes and Rose Art. The company distributes a wide range of construction toys, puzzles, and craft-based products. In 2016, Mega Brands' Bloks was second in worldwide sales (11%) of toy construction building sets. History Ritvik Holdings In 1967, Victor Bertrand and his wife Rita founded the company as Ritvik Holdings (RH). Ritvik is a portmanteau word based on a combination of ''Rit''a and ''Vic''tor. RH began by distributing toys made outside Canada and also facilitated contracts between foreign brands and Canadian manufacturers.Mega Bloks Inc. Ritvik later became a vertically integrated company as it expanded by adding plastic injection molding operations, design operations, tooling manufacturers, and marketing service ...

Magnetix
Magnetix is a magnetic construction toy consisting of a combination of plastic building pieces containing embedded neodymium magnets, and steel bearing balls that can be connected to form geometric shapes and structures. Designed to be a cheaper version of the Geomag magnetic construction set, Magnetix's image suffered severely when an early manufacturing defect caused a death, and was subsequently sold under several different brands after the defect was corrected. The spheres are to in diameter (larger than Geomag), approximately in weight, and are prone to surface corrosion, unlike most other magnetic construction toys. The bars with magnets at each end are long, or , or and flexible, or short rigid curves. Panel shapes include two types of interlocking triangles, interlockable squares, and circle or disks. The triangles and squares identify the North-South polarity of one of their embedded magnets. The disks identify all four magnets. Popularity According to ''TD Monthly ...

Backward Compatibility
Backward compatibility (sometimes known as backwards compatibility) is a property of an operating system, product, or technology that allows for interoperability with an older legacy system, or with input designed for such a system, especially in telecommunications and computing. Modifying a system in a way that does not allow backward compatibility is sometimes called " breaking" backward compatibility. A complementary concept is forward compatibility. A design that is forward-compatible usually has a roadmap for compatibility with future standards and products. A related term from programming jargon is hysterical reasons or hysterical raisins (near-homophones for "historical reasons"), as the purpose of some software features may be solely to support older hardware or software versions. Usage In hardware A simple example of both backward and forward compatibility is the introduction of FM radio in stereo. FM radio was initially mono, with only one audio channel represented ...
