摘要： An electronic device includes a speaker configured to output an inaudible acoustic signal, one or more microphones configured to receive a first reflected wave signal, a memory storing one or more instructions, and one or more processors configured to execute the one or more instructions to obtain a signal change amount based on a correlation between a reference signal corresponding to the inaudible acoustic signal and the received first reflected wave signal, based on the signal change amount exceeding a first threshold value corresponding to a movement of an object, obtain object location information corresponding to a location of the object in a spatial structure based on the signal change amount, and based on the signal change amount exceeding a second threshold value corresponding to a change in the spatial structure, update a final parameter set corresponding to the inaudible acoustic signal by using a waveform optimization model.

摘要： The present disclosure relates to a computer-implemented method for detection of an impact on automotive glass. The method comprises obtaining, for each respective sensor of at least three sensors, each at a respective predetermined location on or in proximity to the glass, a respective time of flight, at the respective sensor predetermined location, of a vibration wave generated by an impact on the glass. The method further comprises computing an impact location based on the predetermined locations and on the obtained times of flight. This constitutes an improved method for detection of an impact on automotive glass.

摘要： A system and method for acoustically measuring a curved object (Obj). A flexible sheet (20) is provided with an array of acoustic transducers (10). The flexible sheet (20) is wrapped around the curved object (Obj) such that the acoustic transducers (10) acoustically contact the curved object (Obj). The acoustic transducers (10) are used to generate and/or measure acoustic waves (W) at variable locations depending on a shape of the curved object (Obj). Spatial coordinates (X,Y,Z) of the acoustic transducers (10) are determined, while the flexible sheet (20) is wrapped around the curved object (Obj). In particular, the spatial coordinates are determined based on respective subsets of travel times (Ta,Tb,Tc) used to calculate respective wave directions of the acoustic waves (Wa,Wb,Wc) arriving at respective subarrays (10a, 10b, 10c) from a common origin, e.g. scattering element (S) inside the curved object (Obj).
