Abstract: Systems and methods for improving a golf swing are described. Deviated motions are detected and, in response to the deviated motion, feedback, such as, for example, an electric shock, is provided to the source of the deviated motion.

Abstract: A method and apparatus for making inexpensive, form-fitted, protective cases of thermal plastic or polycarbonate material that can be easily printed with decorative imagery and/or electronic circuitry for a variety of products, such as portable music players or radios, cell phones, lap-top computers, and the like. The method involves creating a tool having substantially the same surface dimensions of a product. An element is then molded from bulk film of thermoplastic material using the tool. Once the element is molded, it is trimmed from the bulk film. The resulting apparatus is a protective case intended to form-fit over the surface features and dimensions of the actual product used to define the tool.

Abstract: A switchable cable that can selectively deliver power to a computing device either from a primary or an alternative power source is described within. The cable can also be set so that no power is delivered to the computing device through the cable. The cable can be any of a variety of cables that transmit both data and power.
