ABSTRACT:
A transistor logic device uses a signal from a transducer responsive to the centrifugal force experienced in or near the strike zone of a baseball bat during the swing to digitally process and numerically display numerals representative of the maximum centrifugal force experienced during the swing. Knowledge of the maximum force during the swing is useful on a comparative basis in improving batting performance and the speed of the swing can be computed or the displayed numbers can be converted into numbers revealing swing speed in miles per hour or other units. The use of digital data, dealt with digitally, and displayed digitally simplifies, and reduces the cost and size of the apparatus to allow it to be integrated within an actual baseball bat.
