20150258402 | BASEBALL BATTING TRAINER - A batting swing trainer, including a laser for generating a laser beam, a photodetector spaced apart from the laser so as to define a swing space through which a batter swings a bat and for detecting and sensing disruptions in the laser beam, and a microcontroller. The system further includes a speaker for emitting audible signals in relation to which a batter attempts to time swings and a user interface for a user to input pitch data into the microcontroller. When a batter swings a bat through the swing space so as to disrupt said laser beam, the microcontroller detects and measures changes in the laser beam and calculates bat speed, a ball contact time, and the difference between the contact time and the target time, and then provides to the user a visual indication of the effect of the swing. | 09-17-2015 |
