Abstract
Vibration pickup, based on an acceleration pickup, and from which is obtained the signal for the general time derivative, fractional derivative, of the displacement, whose degree is greater than two. The invention makes use of the non-linear portion 6 of the acceleration pickup and the integration is done by means of mass, dampening and spring which are inside the pickup. Already known methods are limited to using the linear region 5 of the acceleration pickup, and thus must also use additional derivators or they must perform calculations. <IMAGE>
