ABSTRACT:
A new Speed Measuring Sports Goal System for measuring the speed of a shot into a sports goal. The inventive device includes a pair of motion sensors positioned in-line and perpendicular to the entrance of a sports goal for sensing an object shot into the sports goal, a control unit connected to the motion sensors for calculating the speed of the object, and a display unit for providing a visible readout of the speed. The motion detection beams generated by the pair of motion sensors are parallel to one another and substantially perpendicular to the path of the object shot into the sports goal. The control unit detects when the object traverses the motion detection beams and calculates the speed of the object based on the time of travel between the motion detection beams.
