515 results about "Motor racing" patented technology

Auto racing (also known as car racing, motor racing, or automobile racing) is a motorsport involving the racing of automobiles for competition.. Auto racing has existed since the invention of the automobile. Races of various sorts were organised, with the first recorded as early as 1867.

Fixed-Odds/Pari-Mutuel Racing Product

The present invention relates to a wagering system that satisfies pari-mutuel regulations while offering patrons fixed-odds at the time the wager is made. More specifically, the present invention is directed to a method of providing a fixed-odds pari-mutuel wagering system for wagering on entries in a race wherein the system may include the steps of opening the wagering system with an initial pari-mutuel pool at initial fixed-odds for each entry in the race; batching the bets received at the fixed odds in a given entry and evaluating each proposed wager at the initial fixed-odds, to determine whether it would satisfy a predetermined pari-mutuel calculation; accepting or rejecting each proposed wager at the initial fixed-odds, in whole or in part, based on the previous determination; placing rejected, in whole or in part, wagers in a queue for later evaluation; based on one or more predetermined criteria, closing the initial pari-mutuel pool to further wagering; providing a subsequent pari-mutuel pool with optionally modified fixed-odds for each entry in the race, batching and evaluating each new proposed wager and each previously rejected wager placed in the queue at the optionally modified fixed-odds, to determine whether it would satisfy a predetermined pari-mutuel calculation; accepting or rejecting each proposed wager at the optionally modified fixed-odds, in whole or in part, based on the previous determination; based on one or more predetermined criteria, closing the subsequent pari-mutuel pool to further wagering; optionally repeating the previous steps as necessary before closing the wagering system.
