摘要： Transducer structures for use in volume flow measurements which generate a first uniform beam and a second focused beam within the uniform beam. The transducer may include concentric elements, a linear array, or combinations thereof. In a two element concentric array, a central disc generates a uniform beam and a peripheral annular element having a lens thereon defines a second focused beam within the first beam. In a linear array, a plurality of juxtaposed linear elements define a scan surface, and a segmented element within the linear element array defines a focused reference sample volume within the scanned surface. A concentric array having a plurality of annular elements is driven with amplitude weighting of each element, in accordance with a Fourier-Bessel approximation to the desired beam pattern, thereby electronically achieving ultrasonic beam width control.

摘要： A piezoelectric, acoustic vibration detecting element is positioned in a fluid flow to be measured so as to be moved according to the intensity of the fluid flow away from a source of acoustic vibration. As the distance between the acoustic vibration source and the element increases with increasing fluid flow intensity, reducing the acoustic pressure on the element, the magnitude of an electrical output signal produced by the element decreases providing a detectable measurement of the change in the fluid flow intensity.

摘要： A transducer assembly holder is mounted through the wall of a fluid conveying structure and includes an acoustic window in communication with the fluid. A transducer assembly is positioned within the holder and has a transducer active element encapsulated in an elastomeric material. The assembly is positioned up against the window of the holder and a spring force is applied to the assembly through a spacer tube or rod. The arrangement is such that the spring force is transferred evenly over the encapsulating elastomeric material and a pressure bond is created between the transducer active element and the acoustic window, such couplings being essential for proper transducer operation.

摘要： A method is provided for supporting flight operations of vertical takeoff and landing (VTOL) aircraft in an urban air mobility (UAM) environment that includes a vertiport. The method includes accessing first observed weather data obtained by sensors located on-site at the vertiport and second observed weather data obtained by sensors onboard VTOL aircraft. A data fusion is performed to integrate the first observed weather data and the second observed weather data to produce a collection of weather data that describes the weather in an environment of the vertiport, and an environment of the VTOL aircraft. And a weather map is produced based on the collection of weather data, the weather map illustrating one or more meteorological features of the weather in the environment of the vertiport and/or the VTOL aircraft, the weather map produced for use in supporting flight operations of the VTOL aircraft.

摘要： Provided are a three-dimensional (3D) ultrasonic anemometer, a 3D wind velocity measuring method, and a wind turbine. The 3D ultrasonic anemometer includes: an ultrasonic sensor including three pairs of ultrasonic transceivers arranged in different directions, wherein the ultrasonic sensor is installed at a rotation body rotating around a rotation axis and rotates around the rotation axis together with the rotation body; a signal processor outputting a 3D sensed wind velocity sensed by the ultrasonic sensor; and a coordinate converter converting the 3D sensed wind velocity into a 3D fixed wind velocity on a fixed coordinate system by using a rotation angle φ of the rotation body.

摘要： The invention relates to a flow measuring instrument which ascertains the water level of a watercourse, the flow rate of the watercourse at a specific location, and the wind velocity at the location of the measuring instrument, and these three measurement data are incorporated in the calculation of the average flow rate of the watercourse and/or of the calculation of the flow. By taking the wind velocity above the watercourse into consideration, calculation of the flow can be improved.
