Abstract: The present invention describes a system for taking the necessary energy for operating the electronic circuit for monitoring a bearing (A) directly from the rotation movement, namely from the kinetic energy of the bearing i.e by energy harvesting or scavenging. All information read on board the bearing (A) by the sensors (4a, 4b) are sent through radio with a wireless communication system to an external data collecting and processing unit (6), that is able to evaluate and communicate the status of the bearing (A) being analyzed. The preferred system embodiment provides that the generator (1) bases its operation on the gyroscope (or Coriolis force) effect a circuit (7) for accumulating the necessary energy for turning the system on.

Abstract: A device is described for generating energy. The device includes at least two ultralight airfoils rotating along their own axis, which functionally reproduce the characteristics of a propeller. The ultralight airfoils which characterize such aerodynamic configuration use pulling members (such as cables or tie-rods) to keep their shape when operating. An important weight reduction of the structure is thus obtained, which allows different applications in the aeolian generation field.

Abstract: A wide-band, single-axis or multiple-axis accelerometer or acceleration-measuring sensor, self-recognising its calibration is described, comprising at least one accelerometric detecting unit, such group being composed of at least two accelerometric transducers adapted to read, in a parallel way, different frequency bands, at least one electronic circuit for conditioning and digitising signals coming from the accelerometric detecting unit and at least one microprocessor adapted to read the signals through the conditioning and digitising electronic circuit and to recombine them for every measuring axis into at least one global output signal.
