Patent ID: 7878916

Claim:
An imaging system for determining the kinematics of an object swung by a player, comprising: an ultrasonic trigger positioned in front of a target area through which an object passes, operable to determine the movement of the object, wherein the ultrasonic trigger comprises at least one emitter and at least one receiver, and wherein the movement of the object comprises the velocity and spatial position of the object; a computing device operatively connected to the ultrasonic trigger and operable to receive the velocity and spatial position of the object; an imaging device operatively connected to the computing device and operable to capture consecutive optical images of the object, wherein the imaging device receives a dwell time and number of consecutive optical images based on the movement of the object; wherein the ultrasonic trigger emits sound waves periodically using pulses, and a time period between the pulses is greater than or equal to twice a distance from the ultrasonic trigger to the target area.
