Abstract
A member (e.g. baseball bat) including a switch manually operable to obtain the transmission of signals by a transmitter in the member to an apparatus for propelling an element (e.g. ball) toward an individual holding the member. The element is propelled by a propulsion mechanism in the apparatus toward the individual holding the member so that the individual can practice receiving the element (e.g. hitting the ball). The apparatus propels the element upon the receipt of the transmitted signals and prepares for the next element in the apparatus to be propelled upon a receipt of subsequent signals from the transmitter.
