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 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.

Abstract: A vacuum pumping system has at least two vacuum pumping devices with vacuum pumps, local electronic control units for monitoring and controlling the operating parameters of the pumps and a control station remotely located relative to the vacuum pumping devices. The control station is equipped with a remote control unit. The remote control unit and local control units are equipped with wireless communication modules for communicating data and commands and controlling the operation of the vacuum pumping devices. The wireless communication module of the remote control unit directly communicates with the wireless communication modules of the local control units.
