Abstract: A traction control method and device for a vehicle is disclosed. In the method, an actual slip of a wheel of the vehicle is made available, a filtered actual slip is determined adaptively from the actual slip by an adaptive filter, the filtered actual slip is passed on to a controller, and the engine torque is set by the controller as a function of the filtered actual slip and of a target slip.

Abstract: The present invention describes the use of nanophase materials, chiefly aluminum, in musical instrument construction. Nanophase materials have constituent grains that are substantially smaller than those of conventional materials, imparting greater strength and deformation resistance. Aluminum has excellent acoustical qualities for making musical instruments, but its use was previously limited due to material weakness of pure aluminum and due to unfavorable, metallic sounding acoustics of aluminum alloys. The present invention also describes the use of aluminum composites in musical instrument construction to further strengthen the material composition used. The use of nanostructured materials in musical instrument construction, e.g. to make soundboards, provides exceptional, premier acoustical qualities as well as great strength and durability.

Abstract: A speed measuring device is provided for use as a diagnostic tool to analyze the sub-cyclic dynamic performance and to monitor the condition of moving elements within a mechanical or electromechanical system. Substantially instantaneous, absolute speed measurements are derived from elapsed time measurements between successive sensing of fixed, equal, position events such as generated by incremental position pulses of a shaft position encoder; said encoder being attached to one of the moving elements within the said system. An assessment of the dynamic performance and condition of the system is ascertained by comparing the speed profile with previous speed profiles obtained during normal system operation. Comparative differences in the said profiles provide an indication of changes of the driving and friction forces within the system which, in turn, can provide an indication of faulty elements.
