Abstract: A system for improving performance and reducing injuries due to improper body mechanics in sports such as baseball, football, and tennis includes equipment for capturing visual images of the person's physical motion over time and a computing device for receiving these visual images and converting them into a graphical representation of the person's physical motion. The system also compares and displays this graphical representation of the person's physical motion with a graphical representation of an ideal standard of the same physical motion in real time on a display screen and provides real time feedback instructions to the person for improving the physical motion performance based on the comparison results.

Abstract: A system for capturing and displaying the motion of an object includes a first equipment for capturing a first set of visual images of the object's motion over time and a computing device for receiving a signal of the first set of visual images of the object's motion and converting the signal of the first set of visual images into a graphical representation of the object's motion. The system displays the graphical representation of the object's motion on a display screen in real time with the capturing of the first set of visual images. The system may also include a second equipment for capturing a second set of visual images of the object's motion over time and the computing device then combines the first and second set of visual images to provide a real-time three-dimensional graphical representation of the object's motion.

Abstract: A refractory setter device for supporting glazed ceramic ware incident its firing within a kiln comprises an open spider having an upwardly facing surface above which the ware article is to be supported with such surface having a plurality of conical pockets arranged in at least three radial locations relative to the center of the spider and a spherical ball engaged within the conical pocket at such three radial locations, such that the ceramic ware article when supported on the setter device has three point contact engagement with the spherical balls.
