Description

ABSTRACT:
The present invention is a pressure indicating ball for training baseball or softball pitchers. The ball contains a mass/weight control material to give the ball the proper heft. The ball has a perimeter envelope fillable by means of a valve located on a flexible exterior surface of the ball. The envelope is filled with a pressure indicating substance that allows an imprint of the pitcher's fingers to be created in the ball's flexible exterior surface. The ball is provided with a number of pressure transducers for sensing pressure exerted on the ball and translating pressure into electrical impulses. The electrical impulses are then transmitted to means for processing electrical impulses, such as a summation circuit, via a battery powered electrical circuit. The summation circuit is, in turn, electrically connected to a digital readout screen located on the ball's exterior surface where pressure data is displayed. Alternately or additionally, the summation circuit is electrically connected to a transmitter provided with an antenna that transmits the pressure data to a remote receiving device for display.
