Really, a patent issued today directed to a method of correcting your golf swing over the internet. I know, hard to believe.

The patent is USPN 7494430 titled “System and Method for Correcting Golf Swing Using Internet” and describes the invention as:

The present invention relates to a system and method for correcting a golf swing using the Internet, which allows a golfer to correct his golf swing through the use of the Internet, thus improving the golfing ability of the golfer. The system of the present invention includes photographing means, image processing means, weight center detecting means, club head detecting means, signal processing means, control means, display means, practice center communication means, personal communication means, a Web server, a three-dimensional data generating server, a golf swing managing server, and a mail server. The system of the present invention can provide moving pictures of golf swing practice and golf swing correcting data via the Internet, so a user's golf swing can be easily corrected at a golf practice center, home or office.

Nothing a few flowcharts can’t clear up!

Got it? Check out this claim from the patent:

A system for correcting a golf swing using the Internet, comprising: photographing means for photographing a golf swing of a golfer and outputting corresponding data; image processing means for receiving data output from the photographing means, image-processing the data and outputting corresponding image data; weight center detecting means for detecting movement of a center of weight during a golf swing and outputting a corresponding detection signal; club head detecting means for detecting an angle and a speed of a club head and outputting a corresponding detection signal; signal processing means for receiving the detection signals output from the weight center detecting means and the club head detecting means, computing the movement of the center of weight and the angle and speed of the club head within an impact zone and outputting corresponding computation data; control means for receiving the image data and the computation data output from the image processing means and the signal processing means, respectively, synchronizing the image data and the computation data and outputting moving picture data; display means situated in front of a golf ball positioned in front of the golfer for displaying a currently performed golf swing, and receiving and displaying the moving picture data output from the control means; practice center communication means for receiving and transmitting the moving picture data output from the control means, receiving and transmitting a request for provision of golf swing correcting data and a request for provision of moving pictures obtained during golf swing practice in response to a key manipulation of the golfer, and receiving and displaying golf swing correcting data and moving pictures obtained during golf swing practice; personal communication means for receiving and transmitting a request for provision of golf swing correcting data and a request for provision of moving pictures obtained during golf swing practice in response to a key manipulation of the golfer, and receiving and displaying golf swing correcting data and moving pictures obtained during golf swing practice; a Web server for receiving the request output from the practice center communication means or personal communication means, outputting a corresponding control signal, and outputting golf swing correcting data or moving picture data to the practice center communication means or personal communication means; a three-dimensional data generating server for receiving the control signal output from the Web server, generating a wire frame, that is, three-dimensional posture data of the golfer, comparing this generated wire frame with a stored reference wire frame, and outputting golf swing correcting data, wherein generating the wire frame includes: a three-dimensional posture data generating server receiving moving picture data from practice center communication means through the Web server and converting each frame of the moving picture data into an image, image-processing the converted images to images of certain size, converting each frame of the moving picture data into an image, image-processing the converted images to images of a certain size, setting joint points of a golfer using the processed images, extracting parameters associated with movement of the golfer using the set joint points, extracting angle data of each changed joint of the golfer using the parameters, and generating the wire frame of the golfer using angle data corresponding to each image; a golf swing managing server for receiving the control signal output from the Web server, storing moving picture data of golf swing practice of the golfer, and outputting the stored moving picture data; and a mail server for receiving the control signal output from the Web server, and outputting various golf information to the practice center communication means or personal communication means via e-mail.

Holy mackerel, it seems like it would be hard to infringe that claim!
