Abstract: Device and methods for a ski assembly system and snowboard assembly system having a ski or snowboard with a centerline axis, a perpendicular axis, and a ski suspension system. The ski or snowboard suspension system has a suspension platform with two or more struts rotatably coupled with the suspension platform and at least one of a front mount assembly and a rear mount assembly.

Abstract: This invention relates to a slip-resistant, flexible polyolefin thin film having first and second opposed, generally planar surfaces, the film comprised of vulcanized comminuted rubber particles of between 20 to 30 mesh size and, a thermoplastic low molecular weight polyolefin polymer, wherein the rubber particles are generally evenly distributed in planar orientation throughout the film, and, wherein the rubber particles are biased in their transverse placement within the thin film toward said second surface of the thin film.An inventive process for producing the thin film described above is also disclosed.

Abstract: A synchronous demodulator is configured so as to extract gyroscope position nformation in a polar coordinate format and then resolve it into position information in a more useful cartesian coordinate format. The technique involves integration of a gyroscope cage coil signal over integration intervals controlled by spin reference signals rather than by the commonly noisy cage coil signal. Integration of the cage coil signal over intervals controlled by the spin reference signals yields outputs of .lambda. cos .theta. and .lambda. sin .theta. which are subsequently sampled and held and then summed to produce a precession coil drive signal whose phase is in the proper relationship to make the gyroscope precess in the correct direction.
