摘要： The request deals with a procedure in order to find movements of a vibrating corps caused by seismic waves is famous or mechanical stresses, in which the relative information to these movements are transmitted to an adequate complex detector by means of visible and non visible electromagnetic waves which are modulated as a consequence of the movements themselves, forward and backward (DOPPLER EFFECT) along the optical real or virtual axle of transmission of a source of electromagnetic radiations, for the generation and the treatment of the corresponding electrical signals. Figure No 7 table 3-3 shows that, according to the invention, every electrical signal adequately amplified, for example by means of an preamplifier (56), besides being applied to a electronic computer programmed to record in diagrammatic shape in function of the time, is also applied to a sonorous alarm device like a buzzer (58), for example through a switch (57), and/or a visual alarm device, for example a luminous lamp indicator (59), as a warning of collapses or other possible situations of danger.

摘要： A system and method are provided to perform loads-based structural health monitoring (LBSHM) of a dynamical system. The method includes receiving, by at least one computer, sensing data responsive to sensing at least one of a parametrical state and a response of the dynamical system, and determining a Koopman mode and a Koopman eigenvalue. The Koopman mode represents a correlation between the sensor data output by the plurality of sensors. The Koopman eigenvalue represents a frequency component associated with the sensor data and growth or decay of energy associated with the sensor data. The method further includes generating, by the at least one computer, an estimation model to determine a linear estimation based on the Koopman mode and the Koopman eigenvalue that estimates a load response of the dynamical system based on growth or decay of energy associated with the sensor data.

摘要： Noise and vibration sensing includes generating with an acceleration sensor a sense signal representative of the acceleration that acts on the acceleration sensor, and processing the sense signal to provide a processed sense signal having an adjustable signal bandwidth and an adjustable signal dynamic. The signal bandwidth extends between a lowest frequency and a highest frequency of the sense signal, and the signal dynamic is the ratio between a maximum amplitude of the sense signal and an output noise floor generated by the acceleration sensor. Noise and vibration sensing further includes adjusting the signal bandwidth and the signal dynamic in accordance with a control signal so that the signal bandwidth increases when the signal dynamic decreases and vice versa.
