Cheetah Flex-Foot
The Flex-Foot Cheetah is a prosthetic human foot replacement developed by biomedical engineer Van Phillips, who had lost a leg below the knee at age 21; the deficiencies of existing prostheses led him to invent this new prosthesis. The Flex-Foot Cheetah and similar models are worn by Oscar Pistorius and other amputee athletes in the Paralympics and elsewhere. It is made from carbon fibre, and unlike all previous foot prostheses, it stores kinetic energy from the wearer's steps as potential energy, like a spring, allowing the wearer to run and jump. It is now (as of September 2012) made by Össur. Carbon fibre is actually a carbon-fiber-reinforced polymer, and is a strong, light-weight material used in a number of applications, including sporting goods like baseball bats, car parts, helmets, sailboats, bicycles and other equipment where rigidity and high strength-to-weight ratio is important. The polymer used for this equipment is normally epoxy, but other polymers are also used, d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lemelson Foundation
The Lemelson Foundation is an American 501(c)(3) private foundation. It was started in 1993 by Jerome H. Lemelson and his wife Dorothy. Origins Jerome H. Lemelson based the foundation on his personal beliefs about the role of invention and inventors to the US economy. He believed that invention and innovation were keys to American economic success and dynamism. As a young inventor Lemelson conceived of the idea of a foundation that would support and celebrate independent inventors. He organized the foundation as a resource for young inventors and support them with funding, connections to role models, and training that would give emerging inventors the ability to develop, refine, and take their inventions to market.Davidson, Martha"Who Was Jerome Lemelson?"/ref> In 1993, Jerome, his wife Dorothy, and his sons and their families established the Lemelson Foundation.

Half-Life 2
''Half-Life 2'' is a 2004 first-person shooter game developed by Valve. It was published by Valve through its distribution service Steam. Like the original ''Half-Life'' (1998), ''Half-Life 2'' combines shooting, puzzles, and storytelling, and adds features such as vehicles and physics-based gameplay. Players control Gordon Freeman as he joins a resistance movement to liberate the Earth from the control of an alien empire, the Combine. ''Half-Life 2'' was created using Valve's Source engine, which was developed at the same time. Development lasted five years and cost million. Valve's president, Gabe Newell, set his team the goal of redefining the first-person shooter genre. They integrated the Havok physics engine, which simulates real-world physics, to reinforce the player's sense of presence and create new gameplay, and developed the characterization, with more detailed character models and realistic animation. Valve announced ''Half-Life 2'' at E3 2003, with a release date ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blade
A blade is the portion of a tool, weapon, or machine with an edge that is designed to puncture, chop, slice or scrape surfaces or materials. Blades are typically made from materials that are harder than those they are to be used on. Historically, humans have made blades from flaking stones such as flint or obsidian, and from various metal such as copper, bronze and iron. Modern blades are often made of steel or ceramic. Blades are one of humanity's oldest tools, and continue to be used for combat, food preparation, and other purposes. Blades work by concentrating force on the cutting edge. Certain blades, such as those used on bread knives or saws, are serrated, further concentrating force on the point of each tooth. Uses During food preparation, knives are mainly used for slicing, chopping, and piercing. In combat, a blade may be used to slash or puncture, and may also be thrown or otherwise propelled. The function is to sever a nerve, muscle or tendon fibers, or bloo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Secret Service
''The Secret Service'' is a 1969 British science fiction television series created by Gerry and Sylvia Anderson and filmed by their production company, Century 21, for ITC Entertainment. It follows the exploits of Father Stanley Unwin, a puppet character voiced by (and modelled on) the comedian of the same name. Outwardly an eccentric Christian vicar, Unwin is secretly an agent of BISHOP, a division of British Intelligence countering criminal and terrorist threats. Assisted by fellow agent Matthew Harding, Unwin's missions involve frequent use of the Minimiser, a device capable of shrinking people and objects to facilitate covert operations. In hostile situations, the Father spouts a form of gibberish (based on the real Unwin's nonsense language, "Unwinese") to distract the enemy. ''The Secret Service'' was the last Anderson series to be made using a form of electronic marionette puppetry called "Supermarionation". This technique was combined with scale model effects seq ...

Epoxy
Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called ''epoxy''. The IUPAC name for an epoxide group is an oxirane. Epoxy resins may be reacted (cross-linked) either with themselves through catalytic homopolymerisation, or with a wide range of co-reactants including polyfunctional amines, acids (and acid anhydrides), phenols, alcohols and thiols (usually called mercaptans). These co-reactants are often referred to as hardeners or curatives, and the cross-linking reaction is commonly referred to as curing. Reaction of polyepoxides with themselves or with polyfunctional hardeners forms a thermosetting polymer, often with favorable mechanical properties and high thermal and chemical resistance. Epoxy has a wide range of applications, including metal coatings, composites, use in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prosthetic
In medicine, a prosthesis (plural: prostheses; from grc, πρόσθεσις, prósthesis, addition, application, attachment), or a prosthetic implant, is an artificial device that replaces a missing body part, which may be lost through trauma, disease, or a condition present at birth (congenital disorder). Prostheses are intended to restore the normal functions of the missing body part. Amputee rehabilitation is primarily coordinated by a physiatrist as part of an inter-disciplinary team consisting of physiatrists, prosthetists, nurses, physical therapists, and occupational therapists. Prostheses can be created by hand or with computer-aided design (CAD), a software interface that helps creators design and analyze the creation with computer-generated 2-D and 3-D graphics as well as analysis and optimization tools. Types A person's prosthesis should be designed and assembled according to the person's appearance and functional needs. For instance, a person may need a transra ...
