Instant Replay In American Football
In gridiron football, replay review is a method of reviewing a play using cameras at various angles to determine the accuracy of the initial call of the officials. An instant replay can take place in the event of a close or otherwise controversial call, either at the request of a team's head coach (with limitations) or the officials themselves. Replay reviews are utilized in some high school games, and also for many games at the college level and above. Before the 2019 season, the National Federation of State High School Associations (NFHS), which establishes the rules for most high school and youth organizations in the United States (though not for Texas high schools), did not allow replay reviews even when the equipment exists to enable the practice. Effective in 2019, NFHS gave its member associations the option to allow replay review, but only in postseason games. In those leagues that utilize replay reviews, there are restrictions on what types of plays can be reviewed. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vibrating Alert
A vibrating alert is a feature of communications devices to notify the user of an incoming connection or message. It is particularly common on mobile phones and pagers and usually supplements the ring tone. Most 21st-century mobile phones are fitted with a vibrating alert, as are smartwatches. Vibrating alerts are primarily used when a user cannot hear the ring tone (a noisy environment or through hearing loss) or wants a more discreet notification (such as in a theatre). However, when the device is placed on a hard surface, it can often be as loud or louder than a ring tone. The vibrations are often produced by a small electric motor connected to an off-center weight. See also * Phantom vibration syndrome * Smartwatch * Vibrator (mechanical) A vibrator is a mechanical device to generate vibrations. The vibration is often generated by an electric motor with an unbalanced mass on its driveshaft. There are many different types of vibrator. Typically, they are components of lar ...

Pyrrhic Victory
A Pyrrhic victory ( ) is a victory that inflicts such a devastating toll on the victor that it is tantamount to defeat. Such a victory negates any true sense of achievement or damages long-term progress. The phrase originates from a quote from Pyrrhus of Epirus, whose triumph against the Romans in the Battle of Asculum in 279 BC destroyed much of his forces, forcing the end of his campaign. Etymology ''Pyrrhic victory'' is named after King Pyrrhus of Epirus, whose army suffered irreplaceable casualties in defeating the Romans at the Battle of Heraclea in 280 BC and the Battle of Asculum in 279 BC, during the Pyrrhic War. After the latter battle, Plutarch relates in a report by Dionysius: In both Epirote victories, the Romans suffered greater casualties but they had a much larger pool of replacements, so the casualties had less impact on the Roman war effort than the losses of King Pyrrhus. The report is often quoted as or Examples War This list comprises examples of b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Touchback
In American football, a touchback is a ruling which is made and signaled by an official when the ball becomes dead on or behind a team's own goal line (i.e., in their end zone) and the opposing team gave the ball the momentum, or impetus, to travel over or across the goal line but did not have possession of the ball when it became dead. Since the 2018 season, touchbacks have also been awarded in college football on kickoffs that end in a fair catch by the receiving team between its own 25-yard line and goal line. Such impetus may be imparted by a kick, pass, fumble, or in certain instances by batting the ball. A touchback is not a play, but a result of events that may occur during a play. A touchback is the opposite of a safety with regard to impetus since a safety is scored when the ball becomes dead in a team's end zone after ''that team'' — the team whose end zone it is — caused the ball to cross the goal line. The result of a touchback is that the team in whose endzone the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fumble
A fumble in gridiron football occurs when a player who has possession and control of the ball loses it before being downed (tackled), scoring, or going out of bounds. By rule, it is any act other than passing, kicking, punting, or successful handing that results in loss of ball possession by a player. A fumble may be forced by a defensive player who either grabs or punches the ball or butts the ball with their helmet (a move called "tackling the ball"). A fumbled ball may be recovered and advanced by either team (except, in American football, after the two-minute warning in either half or 4th down, when the fumbler is the only offensive player allowed to advance the ball, otherwise the ball is ruled dead at the spot of fumble, except when it is recovered for a loss. A fumble is one of three events that can cause a turnover (the other two being an interception or a turnover on downs). Under American rules a fumble may be confused with a muff. A muff occurs where a player dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Touchdown
A touchdown (abbreviated as TD) is a scoring play in gridiron football. Whether running, passing, returning a kickoff or punt, or recovering a turnover, a team scores a touchdown by advancing the ball into the opponent's end zone. In American football, a touchdown is worth six points and is followed by an extra point or two-point conversion attempt. Description To score a touchdown, one team must take the football into the opposite end zone. In all gridiron codes, the touchdown is scored the instant the ball touches or "breaks" the plane of the front of the goal line (that is, if any part of the ball is in the space on, above, or across the goal line) while in the possession of a player whose team is trying to score in that end zone. This particular requirement of the touchdown differs from other sports in which points are scored by moving a ball or equivalent object into a goal where the whole of the relevant object must cross the whole of the goal line for a score to be a ...

End Zone
The end zone is the scoring area on the field, according to gridiron-based codes of football. It is the area between the end line and goal line bounded by the sidelines. There are two end zones, each being on an opposite side of the field. It is bordered on all sides by a white line indicating its beginning and end points, with orange, square pylons placed at each of the four corners as a visual aid (however, prior to around the early 1970s, flags were used instead to denote the end zone). Canadian rule books use the terms ''goal area'' and ''dead line'' instead of ''end zone'' and ''end line'' respectively, but the latter terms are the more common in colloquial Canadian English. Unlike sports like association football and ice hockey which require the ball/puck to pass completely over the goal line to count as a score, both Canadian and American football merely need any part of the ball to break the vertical plane of the outer edge of the goal line. A similar concept exists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
