Abstract: 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.
Abstract: This invention relates generally to a ball delivery system and method, and more particularly to a ball delivery system where the axis of rotation of the ball delivered from the system can range from perpendicular to the direction of motion of the ball to parallel to the direction of motion. This invention also permits a user to enter information related to the speed and axis of rotation of the ball. This invention also permits information related to the speed and axis of rotation of the ball to be determined from a video of a ball.
