摘要： The equipment (1) comprises first acoustic-electric transducers (2) for providing electrical signals indicative of the noise in a space in the motor vehicle, second electric-acoustic transducers (4), and an electronic unit (6) which, in a first operating mode, can pilot the second transducers (4) in dependence on the signals provided by the first (2) so as to cause the generation of pressure waves (anti-noise) which can cancel out the noise waves. The unit (6) can also selectively implement a second operating mode, alternative to the first, in which it pilots the second transducers (4) so as to cause the generation of pressure waves of predetermined characteristics in said space (3), it detects the signals correspondingly provided by the first transducers (2), it compares predetermined characteristics of these signals with those of reference signals or data previously stored, and it generates alarm and/or locking signals when the characteristics of the signals provided by the first transducers (2) differ from those of the reference signals or data so that, in the second operating mode, the equipment (1) operates as an alarm system against intrusions into said space (3).

摘要： The object of the invention is to make it possible to detect vibrations which would destroy a micro-gravity environment, to grasp factors of the vibrations, to detect and grasp a position and a scale of meteoroid/debris collisions, and to establish a counter-measure. Vibration sensors 2 are disposed in a matrix array on a vibrating body 1 placed in a micro-gravity environment, and the vibration data are collected and fed to a computer 5. The computer 5 analyzes a spectrum of the vibration, in a neural network section a vibration source is specified on the basis of the analyzed spectra, in a fuzzy control section, actuators 6 are driven so as to reduce harmful vibrations in response to the vibration energy and the energy source specified by the neural network section, and if necessary, a vibration factor is eliminated. The computer 5 takes in the result of driving for the actuators 6, the results are learnt in the neural network section and in the fuzzy control section to be ready for generation of vibrations at the next time. The vibration sensor 2 comprises a reflector or a transparent refractor disposed as floating in a micro-gravity space, output means fixed to the vibrating body for emitting energy towards the reflector or transparent refractor, and a receiver fixed to the vibrating body for receiving energy sent from the reflector or transparent refractor and measuring the nature of vibrations of the vibrating body on the basis of movement of the reflected or permeated energy.

摘要： An active adaptive control system introduces a control signal from an output transducer (14) to combine with the system input signal (6) and yield a system output signal (8). An error transducer (16) senses the system output signal and provides an error signal (44). An adaptive filter model (40) has a model input from a reference signal (42) correlated to the system input signal, and an output outputting a correction signal (46) to the output transducer to introduce the control signal. Performance of the model is selectively controlled to control the signal sent to the output transducer. Various monitoring and control methods are provided, including spectral leak signal monitoring and control, correction signal monitoring and control, frequency responsive spectral transfer function processing of the leak signal and/or the correction signal, reference signal processing, and fuzzy logic control.
