The present application is a non-provisional of, and claims priority to, U.S. Provisional Patent Application Ser. No. 62/443,456, filed Jan. 6, 2017, the disclosure of which is incorporated herein by reference in its entirety.
BACKGROUND OF THE INVENTIONEmbodiments of the invention relate generally to sporting events and, more particularly, to the use of RFID-based location identification in athletic equipment and athletic playing fields in various sporting events.
Over the 20 years, the popularity of amateur and professional sports has continued to grow exponentially. By some estimates, amateur and professional sports and the activities associated therewith brings roughly $14.3 billion in earnings a year in the United States, for example. Part of the appeal of amateur and professional sports is the fast-paced, action-packed nature of such events, with sports such as American-style football, basketball, baseball, rugby, tennis and soccer being some of the more popular sports watched by consumers.
In many sports, the location of a player or ball being used relative to an out-of-bounds boundary or other playing field marker/location is important to the game. That is, the occurrence of a player or ball contacting an out-of-bounds boundary may cause stoppage of a play (American football), possession of the ball to go to an opposing team (basketball, soccer) or points being awarded to a player (tennis). Thus, it is recognized that the accurate determination of if/when a player or ball contacts an out-of-bounds boundary is important to the outcome of the game.
An exemplary illustration of the importance of the accurate determination of a player or ball is provided in American football. Organized football games typically include several officials (referees, umpires, head linesmen, line judges, back judges, field judges and side judges) whose primary responsibilities are to monitor play including the position of the football. In recent years, professional football leagues (including the National Football League®) and amateur leagues (including the NCAA®) have adopted the use of video replays to assist officials in reviewing disputed calls during the course of a football game. Often the position of a football during the play is the primary issue under dispute. For example, whether the football crossed the goal line of the end zone during a play, or whether a player's forward progress with the football during a play passed the first down marker on the field of play. The goal line is an imaginary plane extending upward from the line of paint at the edge of the end zone (goal line) on the field of play. These decisions or calls by the officials on the field or in the replay booth can be very difficult at times due to line of sight limitations of the officials and/or the cameras used to film the game action.
Further, the players themselves can increase the difficulty of tracking or determining the position of a football during a play. Because football plays involve tackling and blocking, often the players themselves obstruct a clear view of the football during a play. It is also not uncommon for an official to make an incorrect call on a play due to the position of the official during the play and the angle of the official's view of the play itself. Even video replays can result in incorrect decisions or inconclusive evidence based upon the positions of the video cameras taping the football game. Additionally, player's often attempt to reposition and improve the position of the football after the play has been whistled dead or over by the official. In some instances, the official may not detect such late repositioning of the football by a player. An incorrect goal line or first down call can be a determinative factor in the outcome of a football game.
Video replays have improved the integrity and accuracy of the game official's decisions or calls during a game. However, in many cases, the process of stopping the game to review the video tape evidence of a disputed play can take several minutes. Spectators of football games often find such delays to be too long, boring and/or disruptive to the flow of the game. Many coaches believe a few minute delay to review a disputed call can negatively affect a team's emotional level, and overall momentum. Others believe the time needed to complete a football game in general has been too long, even before the introduction and incorporation of replay reviews of disputed plays.
Therefore, it would be desirable to provide a system or method that improves the monitoring and observation of the football game action to minimize the occurrences of incorrect decisions by officials, particularly those decisions involving the position of the football during a play. It would further be desirable for such a system or method more accurately monitor the football game during play, including the position of the football, without introducing undesirable delays to the football game. Such improving of the monitoring and observation of a game action to minimize the occurrences of incorrect decisions by officials is also desirable in numerous other sports, including but not limited to basketball, baseball, rugby, tennis, hockey and soccer, for example.
