Abstract: A semantics engine is described that produces a semantically-impaired but equivalent version of the original source code that can be compiled and executed using conventional tools for commonly used programming languages. This semantically-impaired source code and the compiled assemblies it produces are incomprehensible to anyone who would attempt to read them. The semantics-impairing process is irreversible both at the source and the assembly levels and the machine code generated by the semantically-impaired source code is exactly the same as that produced by the original source code. The semantics engine achieves confidentiality without using encryption or compression. All protective modifications are made directly to copies of the original source code thereby introducing no intermediate forms of the code.

Abstract: The invention relates to a method and a system for analyzing, teaching and identifying the biomechanics of body motion from a video source. Repeatable body motion activities are analyzed as a series of positions of interest that trigger superimposed smart model animations. The properties of body part images, including location, scale and rotation are determined by a combination of manual and automatic means thereby tailoring the smart models to the underlying video images of the body in motion. Based on the proximity of the subject's actual motion to the ideal-or-expected motion defined for the smart models, quantitative characterizations of the motion performance are made.

Abstract: The invention pertains to a method for interactively tracking, analyzing and teaching a correct golf swing using an apparatus consisting of a computer with an attached video camera and a special club shaft attachment that is monitored to determine the progress of a golf swing in real-time. A short simulated golf club with a matching golf ball platform is provided for use in a limited space. Club position is evaluated at all points along prescribed swing plane orbits for accuracy with regard to club shaft angle, club face rotation and swing plane location. Leading guides are provided to aid in correct club movement. Trailing position reinforcement guides permit the student golfer to use his own initiative and timing while receiving real-time corrections relating to club and body motion. Simulated ball flight is determined and applied to golf practice range and golf course activities.

Abstract: The invention pertains to a method of and apparatus for interactively tracking, analyzing and teaching a correct golf swing. A computer with an attached video camera and display monitor is used to superimpose patterns on the monitor over the golfer's live background image that represent the ideal golf swing. Orbit patterns that are calibrated for each individual golfer are displayed as tracks to facilitate club movement that is geometrically correct. Points along the orbits further serve as reference points for analysis of the correct three dimensional shaft direction, club head rotation and body position. A spherical attachment below the club grip focuses the golfer's efforts to move the sphere within the orbits and enhances the computer's ability to uniquely correlate its patterns to the club's position, shaft direction and club face rotation.
