Baseball pitch-training apparatus
First Claim
1. A baseball pitch-training apparatus, comprising:
- a first sampling region, further including a plurality of first horizontal sampling units and a plurality of first vertical sampling units, the first horizontal sampling units being capable of sensing a first horizontal position of a ball passing the first sampling region, and the first vertical sampling units being capable of sensing a first vertical position of the ball passing the first sampling region;
a second sampling region, located in a rear of the first sample region, further including a plurality of second horizontal sampling units and a plurality of second vertical sampling units, the second horizontal sampling units being capable of sensing a second horizontal position of the ball passing the second sampling region, and the second vertical sampling units being capable of sensing a second vertical position of the ball passing the second sampling region; and
a microprocessor, connected electrically with the first sampling region and the second sampling region, for receiving the respective position signals of the ball generated by the first sampling region and the second sampling region, for determining whether or not the ball passed a strike region, for measuring a speed of the ball, and for calculating a trajectory variation of the ball.

Abstract
A baseball pitch-training apparatus includes a first-sampling region, second-sampling region, and a microprocessor. The first sampling region further includes a plurality of vertical and horizontal sampling units respectively along the vertical direction and the horizontal direction at the front edge of the home plate. The second sampling region is located in the rear of the first sampling region and also includes a plurality of vertical and horizontal sampling units. The sampling units of the present invention are used to generate position signals of a passing ball that will be forwarded to the microprocessor for further parsing the speed and the trajectory variation of a pitched ball, and determining whether or not the ball passed a strike region.
