Abstract

A device for providing information concerning position and movement of a ball, in particular a basketball, to a user is provided. The device includes a ball having an opening therein. A sensor board is positioned within the opening in the ball. The sensor board carries a three-axis accelerometer electrically connected to a microcontroller and a transceiver. A receiver board is also provided and is located remotely from the ball. The receiver board carries a transceiver electrically connected to a microcontroller and a plug for connecting to a personal computer. The accelerometer on the sensor board continuously senses the position and acceleration of the ball. That information is then transmitted wirelessly to the receiving board by the transceivers. The position and acceleration information is then integrated in order to calculate the end position of the ball based on the position and acceleration information and previously input data on the shooter'"'"'s height, distance from the basket and height of the basket. The data is then transferred to a personal computer by a USB connection for display to the shooter.

Claims
