I know almost nothing about the sport of Baseball (apart from the fact that it seems a lot more engaging than cricket or golf).
Undaunted by ignorance, today’s invention is an adaptation to the baseball bat.
This consists of several microphones embedded in the bat surface. When they sense that a ball is nearing for a hit, they cause a weight to be driven axially within the body so that the impact point becomes the centre of percussion. (The weight movement might be effected by eg compressed air).
This allows every impact to occur on a new, specially engineered ‘sweet-spot’.
Even if it doesn’t conform to the rules of competition, it might be useful to novice players, removing the jarring and pain caused by hitting the ball with the wrong part of the bat in training.
