Abstract: A system for visually tracking the trajectory of an in-flight golf ball through an x-y-z space above a driving range includes a plurality of cameras for respectively creating a video stream of the x-y-z space. Each video stream is presented on a dedicated camera focal plane with information on respective azimuth angles ? and elevation angles ? from the particular camera to the in-flight golf ball. A central computer is connected with the camera focal plane of each camera to identify a start point for the golf ball, to track its trajectory in the x-y-z space, and to filter out background clutter. A visual display is provided to show the in-flight golf ball from its start point to a target point in real time.

Abstract: A system and method for including an entertainment aspect in an individual's training/practice session for throwing/kicking/hitting (i.e. launching) a ball, requires recording a video stream(s) that includes images of the individual's body motions and the resultant flight trajectory of the ball. Images from the video stream(s) can then be used, with appropriate metrics, to study the motion kinetics of the individual and the ball's resultant flight trajectory, to evaluate the individual's performance in launching the ball. Also, images from the video stream can be edited by the individual for subsequent training or entertainment purposes.

Abstract: A device to produce a high capacity, low velocity, non-aspirating, semi-cylindrical air pattern, to be mounted in a ceiling. The device has a box-shaped backpan connected to a ceiling air duct and a flow directing assembly attached to the backpan and hanging below the ceiling. The flow directing component has a perforated face panel made up of flat surfaces in horizontal and angular planes, forming a substantially semi-cylindrical shape. Inside the face panel are four vanes that span its length, for controlling the direction of air flow. The flow directing assembly can swing away from the ceiling by a hinge along one side, or can be removed entirely using quick release means.
