摘要： Noise point data is generated by converting a vibration signal, measured at a source (noise point) of the vibration signal at a first time, into a frequency domain. Sound point data is generated by converting the vibration signal, measured at a sound point (different from the noise point) at the first time, into a frequency domain. Deep learning is applied to the noise point data and the sound point data to generate a noise prediction model for predicting frequency data of a vibration at the noise point using frequency data indicating a vibration at the sound point. The noise prediction model is applied to target vibration signal, measured at the sound point at a second time, to predicting target noise point data indicating vibration at the noise point. The predicted target noise point data is used to diagnose a fault at the noise point.

摘要： A non-contact method is presented for measuring vibration on a surface of an object. The method includes: projecting light from one or more light sources towards an area of interest on a surface of an object; detecting the light diffusely reflected by the surface of the object using one or more detectors; determining a change in position of the reflected light detected by the detector over time; for the at least one point on the surface of the object, calculating a series of measurements of vertical displacement of the surface over a period of time from the change in position of the reflected light and using triangulation; and determining frequency of a disturbance of the surface at the at least one point on the surface and an amplitude of the disturbance using the series of measurements of vertical displacement.

摘要： Embodiments of a process for estimating a rotational speed of a rotating component and a process for estimating an acceptable rotor imbalance of a rotating component are provided herein. The process for estimating the rotational speed of a rotating component for a charging system comprises measuring a vibration signal of the rotating component by means of a sensor; and identifying harmonic train members from a plurality of peaked components of the vibration signal. Further, the process comprises determining a candidate fundamental frequency from the harmonic train members; and determining a derived vibration amplitude value from the vibration signal. This determination involves a filtering of the vibration signal, removing periodic contributions having a high amplitude. A scalar value is then derived from the filtered signal as a derived vibration amplitude value, representing the integrated total vibration amplitude of the filtered signal at the current speed. The process comprises verifying a consistency condition between the derived vibration amplitude value and the candidate fundamental frequency using a predetermined speed-amplitude map, associating speed values with their respective derived vibration amplitude values. For determining an acceptable rotor imbalance, a speed-amplitude map obtained at a time when the imbalance is acceptable is compared to a speed-amplitude map at a later point in time. An offset between the maps may indicate an inacceptable imbalance.

摘要： A system for controlling a sound dose of a listener is presented. The system comprises a cloud server operatively connected to a remote storage configured to store a plurality of audio profiles, each comprising sound pressure data and a hearing profile associated with specific users of the system. The system further comprises one or more audio playback arrangements comprising a transducer, a controller, and a microphone arranged to measure a current sound pressure experienced by the listener. The cloud server and/or the controller of said one or more audio playback arrangements comprises controlling circuitry configured to, based on sound pressure data, a hearing profile of the listener and a current sound pressure experienced by the listener, cause estimating of a current estimated time period describing an estimated time until the sound dose of the listener exceeds a sound dose threshold. If the current estimated time period is below a dose period associated with the sound dose threshold, an updated sound pressure is calculated which describes an estimated time until the sound dose of the listener exceeds the sound dose threshold, meets or exceeds the dose period.
