Mechanics Of Oscar Pistorius' Running Blades
The mechanics of the running blades used by South African former Paralympic runner Oscar Pistorius depend on special carbon-fiber-reinforced polymer prosthetics. Pistorius has double below-the-knee amputations and competed in both non-disabled and T44 amputee athletics events. Pistorius's eligibility to run in international non-disabled events is sanctioned by the International Association of Athletics Federations (IAAF). Pistorius began running in 2004 after a rugby knee injury which led to rehabilitation at the University of Pretoria's High Performance Centre with coach Ampie Louw. His first racing blades were fitted by South African prosthetist Francois Vanderwatt. Because he was unable to find suitable running blades in Pretoria, Vanderwatt ordered some to be made by a local engineer at Hanger Orthopedic Group. These quickly broke, and Vanderwatt referred Pistorius to American prosthetist and Paralympic sprinter Brian Frasure to be fitted for carbon-fibre blades by Icel ...

Court Of Arbitration For Sport
The Court of Arbitration for Sport (CAS; , TAS) is an international body established in 1984 to settle disputes related to sport through arbitration. Its headquarters are in Lausanne, Switzerland, and its courts are located in New York City, Sydney, and Lausanne. Temporary courts are established in current Olympic host cities. The International Council of Arbitration for Sport (ICAS) was established simultaneously, and a single president presides over both bodies. The ICAS, which has a membership of 20 individuals, is responsible for the financing of and financial reporting by the CAS, and it appoints the Director-General of the CAS. Jurisdiction and appeals Generally speaking, a dispute may be submitted to the CAS only if an arbitration agreement between the parties specifies recourse to the CAS. However, according to rule 61 of the Olympic Charter, all disputes in connection with the Olympic Games can only be submitted to CAS,International Olympic CommitteeOlympic Charter an ...

Frame Rate
Frame rate, most commonly expressed in frame/s, or FPS, is typically the frequency (rate) at which consecutive images (Film frame, frames) are captured or displayed. This definition applies to film and video cameras, computer animation, and motion capture systems. In these contexts, frame rate may be used interchangeably with and refresh rate, which are expressed in hertz. Additionally, in the context of computer graphics performance, FPS is the rate at which a system, particularly a GPU, is able to generate frames, and refresh rate is the frequency at which a display shows completed frames. In electronic camera specifications frame rate refers to the maximum possible rate frames could be captured, but in practice, other settings (such as exposure time) may reduce the actual frequency to a lower number than the frame rate. Human vision The temporal sensitivity and resolution of human vision varies depending on the type and characteristics of visual stimulus, and it differs betw ...

Fibula
The fibula (: fibulae or fibulas) or calf bone is a leg bone on the lateral side of the tibia, to which it is connected above and below. It is the smaller of the two bones and, in proportion to its length, the most slender of all the long bones. Its upper extremity is small, placed toward the back of the head of the tibia, below the knee joint and excluded from the formation of this joint. Its lower extremity inclines a little forward, so as to be on a plane anterior to that of the upper end; it projects below the tibia and forms the lateral part of the ankle joint. Structure The bone has the following components: * Lateral malleolus * Interosseous membrane connecting the fibula to the tibia, forming a syndesmosis joint * The superior tibiofibular articulation is an arthrodial joint between the lateral condyle of the tibia and the head of the fibula. * The inferior tibiofibular articulation (tibiofibular syndesmosis) is formed by the rough, convex surface of the medial si ...

Epoxy
Epoxy is the family of basic components or Curing (chemistry), cured end products of epoxy Resin, 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 (sometimes called mercaptans). These co-reactants are often referred to as hardeners or curatives, and the cross-linking reaction is commonly referred to as Curing (chemistry), 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 application ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strength-to-weight Ratio
The specific strength is a material's (or muscle's) strength (force per unit area at failure) divided by its density. It is also known as the strength-to-weight ratio or strength/weight ratio or strength-to-mass ratio. In fiber or textile applications, tenacity is the usual measure of specific strength. The SI unit for specific strength is Pa⋅ m3/ kg, or N⋅m/kg, which is dimensionally equivalent to m2/s2, though the latter form is rarely used. Specific strength has the same units as specific energy, and is related to the maximum specific energy of rotation that an object can have without flying apart due to centrifugal force. Another way to describe specific strength is breaking length, also known as self support length: the maximum length of a vertical column of the material (assuming a fixed cross-section) that could suspend its own weight when supported only at the top. For this measurement, the definition of weight is the force of gravity at the Earth's surface (stand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Van Phillips (inventor)
Van Phillips (born 1954) is an American inventor of prosthetics. Biography He is known for the Flex-Foot brand of artificial foot and limbs that he created, and for his charity work for amputees. An amputee himself, having lost a leg below the knee at age 21, Phillips was motivated by the limitations of then-existing artificial limbs to attend the Northwestern University Medical School Prosthetic-Orthotic Center. After graduation, he worked as a biomedical design engineer at the University of Utah before starting his own company, Flex-Foot Incorporated in 1984. Phillips ultimately created a workable artificial foot made from carbon graphite. Unlike all previous prostheses, it stored kinetic energy from the wearer's steps as potential energy, like a spring, allowing the wearer to run and jump. A prosthetic foot that he created, the Flex-Foot Cheetah, is used by double-amputee and Paralympics gold-medalist Oscar Pistorius, and about 90 percent of Paralympics participants use a var ...
