Abstract: An example active noise control filtering with an adaptive filter structure includes a controllable filter matrix with reference and error input signals, and updating the filter coefficients dependent on an optional filtered reference signal and an error signal, the error signal being representative of a performance criterion of the filter module. Further, a leakage functionality and a convergence functionality is applied to the updated filter coefficients. The leakage functionality is controlled by at least one of a flush functionality, freeze functionality, spatial freeze functionality and leakage threshold, and the convergence functionality is controlled by the freeze functionality and spatial freeze functionality.

Abstract: In a strain wave gearing, the addendum tooth profile of an internal gear is defined by the formula a and that of an external gear is by the formula b at a principal cross-section located at a tooth-trace-direction center of the external gear, on the basis of a movement locus (Mc) of ?=1 by the teeth of the external gear with respect to those of the internal gear. It is possible to avoid superimposition of flexion-induced bending stresses and tensile stresses caused by load torque at the major-axis locations of the external gear, and the transmission torque capacity of a strain wave gearing can be improved.
