A team of Pakistani engineers have invented an arm sleeve which will notify the bowlers the degree at which they are flexing their arms in real time. ESPNcricinfo writer Ahmer Naqvi writes, “the ingenuity of it lay in its simplicity and its applications beyond measuring elbow extension”.

Of all the anachronisms that bedevil cricket, none has been as perplexing as the issue of chucking or, with more political correctness, bowling with illegal actions. For much of cricket's history, the rule on the village green was the same as that in international matches - the umpire used the naked eye to determine if an action was illegal.
The emergence of Muttiah Muralitharan, and the discovery early this century that nearly all bowlers had some amount of kink in their actions, belatedly brought science into the equation. The decision to use technology, to rely on biomechanical analysis recorded in labs, arrived from the desire to make things fairer, but it has also made things more confusing.
In a Cricket Monthly article on the question of determining the legality of bowling actions, Osman Samiuddin concluded by saying that the approach to it was "as if cricket's toes are partially dipped into the ocean of science and there is a great wave approaching".
