Abstract: A device which detects and locates an impact on a structure. The device includes at least three acoustic sensors so that an acoustic wave emitted at any point of a measurement space can be received through direct propagation by each of the sensors. The device also includes command controller configured to process the signals corresponding to the acoustic waves received by the acoustic sensors, to detect the occurrence of an impact, and to locate a point of the structure that is the source of an acoustic wave. At least one optical pointer is actuated by the command controller so as to designate an impact point located on the structure by illuminating a corresponding site of the structure.

Abstract: A process for marking the real position and real orientation of a tool in relation to the manipulator arm of a robot. The process utilizes the amplitude measurements of acoustic signals and the flight time measurement of the acoustic waves emitted by an acoustic probe of the tool and reflected by the fixed reference elements. The position of the center of reference of the probe relative to the end of the manipulator arm is determined. The axes X and Y defining the plane of the probe along reference axes X? and Y? of known orientations are oriented so that the modification of the position and of the orientation of the probe in the reference frame can be defined. The displacements of the manipulator arm are managed by the controller based on the position of the probe in relation to the manipulator arm and the reference orientation of the probe.

Abstract: The invention consists of a system allowing remote wireless transfer of energy from a base station to a moving object, in particular a drone, moving in a given zone around the base station. The system includes means for tracking the moving object so as to determine the position of the moving object relative to the base station at any time, means for transmitting a synthetic acoustic wave focused in the direction of the moving object, these two means being located at the base station and powered by the base station, and acoustic reception means, located on the moving object, for receiving the acoustic wave transmitted by the base station and converting the received acoustic wave into an electrical signal and then into a power supply voltage for a battery.
