Abstract: A practice device that can be used with or without a ball to help further develop the feel and muscle memory of a proper swing. A swing training device includes a handle, a shaft and a weight slidably mounted along the shaft. During the swinging of the club, the weight slides from an end near the user's hands to a distal end away from the user. When the weight reaches the distal end, the weight contacts a stop creating an audible “snap,” giving the user both tactile and audible feedback to the success of the swing. The weight preferably includes a friction adjustment device to control the amount of static and/or dynamic friction between the sliding weight and the shaft. The shaft preferably has a constant cross-sectional area or diameter to provide a set amount of friction during the travel of the weight along the shaft.

Abstract: An electrical power generation system comprises a variable capacitor and a power source. The electrical power generation system is configured to generate electric power via movements of the rail. The power source is used in the form of a generator to prime the variable capacitor that effectively multiplies the priming energy of the power source by extracting energy from the passing vehicle. By alternately priming the variable capacitor using charge from the power source and discharging it at a later time in a cyclic manner to change the capacitance, a significantly large amount of electrical energy is produced due to change in capacitance than from the power source itself.

Abstract: An ultra-wideband (UWB) communications system combines the techniques of a transmitted reference (TR) and a multiple access scheme called delay hopping (DH). Combining these two techniques using UWB signaling using a continuous noise transmitted waveform avoids the synchronization difficulties associated with conventional approaches. This TR technique is combined with the DH multiple access technique to create a UWB communications scheme that has a greater multiple access capacity than does the UWB TR technique by itself.
