2. Sports Racquets

“Sport racquets, such as tennis racquets, are well known and typically include a frame having a head portion coupled to a handle portion. The head portion supports a string bed having a plurality of main string segments alternately interwoven with a plurality of cross string segments. Many racquets also include a throat portion positioned between and connecting the handle portion to the head portion. Sports racquets were initially primarily made of wood. Wood racquets were largely superseded by racquets formed of aluminum and other alloys. Aluminum racquets significantly improved the durability and reliability of racquets while increasing the power and strength of the racquets. Typically, aluminum racquets are formed of a drawn or extruded tube curved to substantially form a hoop with the two ends drawn together to form the throat tubes and the handle of the racquet. Today, many racquets are formed at least in part of a fiber composite material. Typically, bundles of high tensile strength fibers, such as carbon or graphite fibers, are coaxially aligned and intermixed with a resin typically formed of a thermoset material into sheets or layers of uncured fiber composite material. Multiple layers of uncured fiber composite material are typically carefully wrapped over a mandrel or an inflated tube to form the shape of a racquet. The wrapped layers are then placed into a mold and cured under heat and pressure to produce a fiber composite racquet frame. Racquets formed of fiber composite material have many advantageous characteristics, such as, for example, being lightweight, providing more design flexibility, and providing exceptional power, control and/or feel.”

1. Sports

“Sport (or, in the United States, sports) is all forms of competitive physical activity which, through casual or organised participation, aim to use, maintain or improve physical ability and provide entertainment to participants.  Hundreds of sports exist, from those requiring only two participants, through to those with hundreds of simultaneous participants, either in teams or competing as individuals.

Sport is generally recognised as activities which are based in physical athleticism or physical dexterity, with the largest major competitions such as the Olympic Games admitting only sports meeting this definition, and other organisations such as the Council of Europe using definitions precluding activities without a physical element from classification as sports.  However, a number of competitive, but non-physical, activities claim recognition as mind sports.  The International Olympic Committee (through ARISF) recognises both chess and bridge as bona fide sports, and SportAccord, the international sports federation association, recognises five non-physical sports, although limits the amount of mind games which can be admitted as sports.

Sports are usually governed by a set of rules or customs, which serve to ensure fair competition, and allow consistent adjudication of the winner. Winning can by determined by physical events such as scoring goals or crossing a line first, or by the determination of judges who are scoring elements of the sporting performance, including objective or subjective measures such as technical performance or artistic impression.

In organised sport, records of performance are often kept, and for popular sports, this information may be widely announced or reported in sport news. In addition, sport is a major source of entertainment for non-participants, with spectator sports drawing large crowds to venues, and reaching wider audiences through sports broadcasting.”
