摘要： The application provides a method for determining a flow speed of a liquid in a fluid conduit. During a signal-generating phase, an impulse signal is applied to a first ultrasonic transducer. A response signal is then received at a second ultrasonic transducer. A measuring signal is later derived from the response signal, wherein the derivation comprises reversing a signal portion with respect to time. During a measurement phase, a liquid moves with respect to the fluid conduit. The measuring signal is then applied to one of the two transducers and a response signal of the measuring signal is measured at the other transducer. A flow speed is derived from the response signal of the measuring signal.

摘要： With an apparatus according to the invention it is possible to detect an object's velocity transverse to the direction of propagation of an interacting field. Such transverse movement is detected by applying a field that oscillates spatially in the transverse direction. The method used in the apparatus is applicable where wave energy is used to sense or detect an object by its scattering properties when using either sound waves or electro-magnetic waves. The movement can be detected according to the field properties. The field represented by the sampling pulse must feature a spatial oscillation in the directions, where the velocity components are of interest. Such a transversely oscillating field is e.g. generated by using apodization on individual transducer elements and a special focusing scheme. The apparatus uses waves of either sound or electro-magnetic radiation. The temporal characteristics are determined by the setup of the emitter (1). The spatial characteristics are determined by the transmitter array configuration (3) and the receiver array configuration (5) and the respective beam formers (2) and (6a, 6b, 6c). The transmit array consists of N elements and the receive array consists of M elements. The transmit beam former and the receive beam former are configured to obtain the spatially oscillating field. The signal received from the interacting objects (4) is processed by the velocity estimator processor (7) for calculation of the velocity vector components by estimating the shift in position as a function of time and the velocity is derived herefrom.

摘要： A system of atmospheric remote sensing instruments that utilize a common phased-array acoustic antenna so as to take temperature and wind measurements over a wide range of altitudes. One of the atmospheric remote sensing instruments in the system is a monostatic SODAR (32) that takes wind measurements by transmitting pulses of acoustic energy into the atmosphere and then measuring received reflected acoustic energy. The acoustic pulses are both transmitted and received by the common phased-array acoustic antenna (36). Another of the atmopsheric remote sensing instruments in the system is a wind profiling radar (34) that takes wind measurements by transmitting pulses of electromagnetic energy into the atmosphere and then measuring received backscattered electromagnetic energy. The pulses are both transmitted and received by a phased-array radar antenna (38). The final atmospheric remote sensing instrument in the system is a RASS (30) that takes temperature measurements by transmitting and receiving electromagnetic energy into the atmosphere.

摘要： The process and device can be used, in particular, for extracting certain parameters from a Doppler signal in ultrasonic medical imaging. The device uses, as an imput parameter, for the calculation of the average frequency the correlation coefficients Im(Cxx) corresponding to the imaginary part of the signal. These coefficients are applied in sequence to a multiplier input (10). The other input receives the weighting coefficients in the form of 0,1/0, 1/π,...,(-1)p+i/πp, where p is the number of weighting coefficients, stored in a register (11). The partial products are accumulated and furnish a representative sum of the average frequency.
