摘要： The present invention concerns a method for determining a distance and an inclination angle of a surface,using an electro-acoustic transducer with a diffraction pattern comprising at least a main emission lobe around the emission axis of the transducer and a side emission lobe, comprising steps of (i) emitting an acoustic excitation signal toward said surface with said electro- acoustic transducer being disposed with an orientation angle so that at least a part of the signal emitted in the side lobe is incident on the surface with an incidence angle smaller than the average incidence angle of the signal emitted in the main lobe, (ii) collecting an echo signal scattered back to the electro- acoustic transducer by the surface, (iii) identifying in said echo signal a local maximum corresponding to a round trip time of the side lobe signal, and a local maximum corresponding to a round trip time of the main lobe signal, and (iv) calculating the inclination angle and the distance of the surface by taking into account the angular shift of the local maximum of the main lobe signal relative to the emission axis of the transducer. The present invention concerns also a device implementing the method.

摘要： Bei einem Verfahren zum Aussenden und Empfangen von Wellenenergie, das insbesondere zur Aktivortung von Zielen dient, wird sendeseitig eine Sendeantenne mit einem elektrischen Signal gespeist und empfangsseitig in dem elektrischen Empfangssignal einer Empfangsantenne das von der Sendeantenne abgestrahlte Signal detektiert. Um das Sendesignal im Hintergrundrauschen zu verstecken und damit die Eigenverratswahrscheinlichkeit des Ortenden drastisch zu reduzieren, wird das elektrische Signal mit einem zeitlichen Verlauf generiert, der eine deterministisch-chaotische Struktur aufweist. Ein die deterministisch-chaotische Struktur des generierten elektrischen Signals charakterisierendes Strukturmaß wird empfangsseitig zur Detektion des Signals im Empfangssignal der Empfangsantenne verwendet.

摘要： An acoustic method and apparatus for measuring the horizontal surface location and depth of any type of underground pipe or conduit, including nonmetallic or nonconductive pipe, such as sewer, gas and water pipes, which cannot be detected with electromagnetic locators. A continuous-wave acoustic signal is injected into and transmitted through fluid (liquid or gas) in the pipe (120). The horizontal surface location and depth of the pipe are determined from an analysis of the phase measurements derived from an array (140) of acoustic measurements, which are made at the surface and approximately perpendicular to the direction of the underground pipe.

摘要： A plurality of ultrasonic transmitters (12) at distinct locations and with distinct transmitting frequencies, direct beams of ultrasonic sound waves at one or more detection regions (16) of space. The amplitude of the ultrasonic sound waves is sufficient to generate from each detection region (16) a sound wave (17) having a frequency corresponding to the difference of the frequencies of the respective ultrasonic sound waves. A receiver (18) disposed proximate to the ultrasonic transmitters detects the generated sound wave. An object occupying the detection region blocks one or more of the beams, and is detected therein when the magitude of the generated sound wave (17) is below a threshold. In another aspect of the instant invention, the ultrasonic transmitters (12) are adapted to transmit pulses forming relatively broad spherical wavefronts (38) which intersect to form a circular detection region which propagate with time, thereby enabling the detection of a profile of an object.

摘要： Aspects of the technology described herein relate to receiving an ultrasound image, automatically determining a location of a specific point on an anatomical structure depicted in the ultrasound image, and displaying an indicator of the location of the specific point on the anatomical structure on the ultrasound image. In some embodiments, the anatomical structure is a bladder. In some embodiments, the specific point is the centroid. In some embodiments, a statistical model determines the specific point. The indicator may be, for example, a symbol located at the specific point, a horizontal line extending through the specific point from one edge of the anatomical structure to another, and/or a vertical line extending through the specific point from one edge of the anatomical structure to another.

摘要： L'invention concerne un procédé de détermination d'une différence de profondeur, ou d'un écart latéral par rapport à la verticale entre deux points (O2, M) d'un milieu subaquatique (E), notamment par mesure d'un temps de propagation d'une onde acoustique. Cette détermination est basée sur un modèle monocouche du milieu dans lequel l'onde est supposée se propager en ligne droite selon une direction de propagation effective, avec une célérité moyenne indépendante de cette direction de propagation. L'invention concerne également un procédé de détermination du profil de ladite célérité moyenne, basée sur les mesures de différences de profondeurs elles-mêmes, une détermination du profil de la célérité locale sur l'intervalle de variation des profondeurs sondées, et un système sonar (10) associé.

摘要： A frequency modulation continuous wave (FMCW)-based system includes an emitter to transmit at least one linearly modulated wave of radiation to a scene and a receiver to receive a reflection of the transmitted wave from one or multiple objects located at different locations in the scene. The system interferes a copy of the wave outputted by the emitter with the reflection of the transmitted wave received by the receiver to produce a beat signal with spectrum peaks corresponding to reflections from the different locations at the scene. The beat signal is distorted due to the non-linearity of the modulation. The system includes a processor to detect a number of spectrum peaks in the distorted beat signal and, only in response to detecting multiple spectrum peaks, jointly determine coefficients of a basis function approximating the non-linearity of the modulation and distances to the different locations at the scene having the objects causing the reflection resulting in the spectrum peaks in the distorted beat signal.
