摘要： Device and method for reduction of signal transients, where the signal is divided into frequency bands, the device at least comprising a transient detector (1), a calculating means, means for delaying a signal (2) and an adaptive filter. In the device an input signal (4) is arranged to both the means for delaying a signal (2) and the transient detector (1) via parallel connection, which both are connected to the adaptive filter (3) the output (5) of which is transient reduced. Characterizing is that the detector (1) detects frequency bands with a threshold function, which indicate presence of transient, and it indicates presence of transient if derivative and/or input signal (4) level exceeds predetermined levels. The detector (1) activates, at the indication of a transient in a frequency band, a calculating means for calculation of a set of filter parameters, describing the gain of the frequency bands, for controlling the transient reduction. If the detector (1) detects presence of transient in only one frequency band, the filter parameters accomplishes a total gain to a level determined by the level of the input signal (4). When the detector (1) no longer detects presence of transient the device goes back to the previous set of filter parameters.

摘要： The present invention is intended as a method for producing an electromagnetic transducer of variable reluctance type, where the transducer's seismic mass side (1) and load side (2) are mounted together in a first step while the inner (12a,b,c,d) and/or outer (13a,b,c,d) air gaps are supplied with shims (14) in order to create balanced air gaps in an axial direction (15) between the bobbin core's arms (8a,b,c,d) and the inner and outer yokes (5a, b respectively 4a, b), whereupon in a second step the bobbin core (8) is fixed through the side piece (9) to an adapter (11 ) already attached in a corresponding free moving end of a spring suspension (3), with compliant properties working in an axial direction and arranged between the seismic mass side (1 ) and the load side (2) in resting state in order to maintain balanced air gaps when finally, in a third step, the shims are removed and the air gaps are released.
