Even for those events in which timing is a record, speed is still a significant training item. Two instances out of many are the running pace in board jump and the batting speed in baseball game. Therefore, a system that can measure a variety of speed patterns is developed in order for different kinds of sports. In the system to be implemented, laser is utilized to detect the accurate arrival time of the object through a point; to avoid the wires all over the field, telemetry is applied to transmit the arrival time signal to the Notebook computer; finally, the Notebook computer calculates the velocity and acceleration of the runner in a real time manner, and it also can save and display the running message with its powerful data processing capability. For example, a window program is used to simplify the operation procedure which largely increase the flexibility and convenience in use of the system. The whole system comprises various technologies with friendly user''s interface, and it could become a very useful tool and instrument for athletics and coaches in the training process.
