Abstract
A device for calculating the speed of movement of a ball utilizing a sensing unit having an aperture at the surface of the ball and a receiving unit within the ball that measures reflected signals generated by the sensing unit. A distance measuring feature fixes a value for a particular distance of flight of the ball and a transducer receives a signal indicating the termination of the flight of the ball. A processor calculates the speed of the ball utilizing the absence of a reflected signal through the aperture and the beginning of a stop signal generated by the transducer as the basis for the time span of flight of the ball.
