System for, and method of, indicating to a child the accuracy of shooting a basketball to make a basket

摘要

In a preferred embodiment of the invention, a backboard, a rim on the backboard and a net extending from the rim are provided for a child shooting a basketball. A first sensor on the backboard produces a first signal when the basketball hits the backboard. A second sensor disposed relative to the rim produces a second signal when the basketball hits the rim. A third sensor disposed relative to the net produces a third signal when the basketball passes through the net. The first, second and third sensors may respectively include first, second and third switches which respectively close when the basketball hits the backboard, when the basketball hits the rim and when the basketball passes through the net and which respectively cause the first, second and third signals to be produced when they close. The first, second and third signals may be processed as by a microprocessor to provide an indication of the path of movement of the basketball relative to the backboard, the rim and the net. The processing of the first signal relative to the second and third signals may be delayed to coordinate the operation of the microprocessor in indicating the path of movement of the basketball relative to the backboard, the rim and the net. Similarly, the processing of the second signal may be delayed relative to the processing of the third signal. The path of movement of the basketball may be indicated on a sensory basis such as orally and in a manner to offer encouragement to the child.
