A processing system for processing signals from a plurality of transducers of an ultrasonic sensor in order to determine characteristic information relating to an object detected by the ultrasonic sensor is provided. The system comprises a coupling device for transforming the signals received from the transducers into pulses, and a pulse processing unit for determining the characteristic information based on the pulses delivered by the coupling device. The coupling device comprises: a thresholding unit for applying, for each signal received from a transducer, thresholding to a signal derived from the signal received from the transducer and extracting directional information contained in the phase of the derived signal; a transformation unit for transforming the derived signal into pulses containing the phase of the signal, using the information extracted by the thresholding unit.

An acoustical treatment assembly includes an absorption panel and a diffusion panel that may be removably mounted to the absorption panel. The absorption panel has a first surface, an opposite second surface and a plurality of edge surfaces. The absorption panel has channels defined in either or both of the second surface and the edge surfaces. Each channel has a seat spaced apart from the first surface and the second surface, in which is disposed a magnet. The diffusion panel has a first surface, a second surface and a plurality of interior openings extend from and through the first surface and the second surface. The diffusion panel is formed of a material having a lower audio absorption than the absorption panel. Additional magnets are mounted on the diffusion panel that cooperate with magnets of the absorption panel to removably retain the diffusion panel adjacent to the absorption panel.

This invention claims a patent on the process of propagating soundwaves through bodies of water, such as oceans, to produce and direct winds, for the purpose of managing aerial weather systems. Propagating soundwaves within water can generate and direct wind for many purposes. One purpose is to effectively weaken storms, by directing wind-shear against a storm's momentum, and stripping it of precipitation. Another purpose is to guide atmospheric rivers, and manually re-direct clouds in the precipitation cycle. This inventive process grants methods to mitigate dangerous weather patterns, such as droughts and hurricanes. The invention introduces a new subject matter that distinguishes it from other inventions relevant to underwater acoustics: manual processes to moderate weather.

A luminous film has a plurality of light-emitting diodes, a carrier layer and a light-conducting layer having microoptical structures which make it possible to deflect multidirectionally emitted light in a common emission direction of the luminous film, in order to allow uniform illumination of the luminous film surface with a low light-emitting diode population of the luminous film.
