Abstract

The pitcher'"'"'s workout machine has a frame assembly which includes three rectangular light panel frames connected to define a box shaped target zone. The first and second frames mount infrared transmitters and receivers in a pattern defining a rectangular strike zone, with a ball zone above, below, and on opposite sides of the strike zone. Lenses are used to collimate the infrared beams. When a ball passes through the frame assembly, the first frame triggers a pulse generator and the third frame stops the pulse generator. Shift registers count the pulses, and the speed is determined by the predetermined distance between the first and third frames. Shift registers count balls and strikes, and calculate the number of balls, strikes, walks, outs, and innings, which are displayed on a display panel.
