No-ball sensor
Wrong No-Ball Decision can be turn the things around sometimes. If the Umpire fails to detect a no ball, then a batsman will have to miss 1 extra Ball, that too free-hit, and one score on the board or sometimes he may lose his wicket. On the other hand, wrong no-ball decisions not only add an extra run to the scoreboard but also gives a free-hit to the batsman. With this in mind, Cricket Australia approached the famous university technology development company
To sort out this problem, Cricket Australia once approached the famous university technology development company QutBlueBox to create a device that gives audible feedback when a bowler oversteps the line. The principle of the device is pretty simple, it works like a door chime. It’s often seen during tennis matches. It will shine a light sensor from one side of the popping crease which is can be easily picked up by the reflector strip placed on the other opposite side. Once a bowler oversteps, the speakers will give a beeping sound.
