Abstract: Method for determining a characteristic of detection and/or identity information and/or location information of a receiver, wherein: a) a primary wave is emitted by an antenna, b) adjustable elements are controlled with a plurality of sets of parameters, to modify the propagation of a primary wave and/or of a secondary wave coming from the receiver, and c) signals received by the antenna are saved, and d) the characteristic of the receiver in the medium is determined based on the signals received for each set of parameters.

Abstract: A communication network includes an access point, a control unit in communication with the access point, a wave shaping device in communication with the control unit, and a wireless communication device. The control unit determines parameters of the wave shaping device, the parameters being search parameters if the control unit does not receive a pilot signal, and optimization parameters if the control unit receives a pilot signal.

Abstract: An incident wave is emitted into a medium comprising diffusers that can reflect the wave. Signals representing a reflected wave reverberated by the medium from the incident wave are captured, said captured signals being the sum of a simple diffusion component and a multiple diffusion component. The captured signals are treated by separating the multiple diffusion component from the simple diffusion component.

Abstract: A method for probing by wave propagation, in which an incident wave is emitted into a medium comprising diffusers that can reflect the wave. Signals representing a reflected wave reverberated by the medium from the incident wave are captured, said captured signals being the sum of a simple diffusion component and a multiple diffusion component. The captured signals are treated by separating the multiple diffusion component from the simple diffusion component.

Abstract: The invention relates to a spotlight (2) for a motor vehicle that has a light source (4) producing a beam of light which is directed along a first axis (X) intended to be oriented towards the front of the vehicle and a lens (6), wherein the light source (4) projects all of the beam directly onto the lens (6) without reflection nor obturation, and the lens (6) is arranged to move in rotation about a second axis (Z) intended to be oriented towards the top of the vehicle.

Abstract: The invention relates to a wave-propagation-based sounding method, in which: an incident wave is emitted through a medium including diffusers capable of reflecting the wave; and, subsequently, signals representing a reflected wave reverberated by the medium from the incident wave are captured, said captured signals being the sum of a single scattering component and a multiple scattering component. The captured signals are processed by separating the multiple scattering component from the single scattering component by filtering at least one frequency transfer matrix representing responses between transducers from the transducer assembly.
