摘要： The position of a submerged object towed at great depth from a ship is determined, with respect to the ship, from measured values of the travel time of acoustic pulses between the ship and the object. These pulses are emitted at different locations of the ship and received at a point of the object. The values of the travel times of the pulses are measured and digitized on the object and transmitted by cable to the ship where they are processed, in combination with values representing the distances between the emission locations, to determine the coordinates of the object with respect to a system of axes associated with the ship.

摘要： Acoustic positioning device for a vessel comprising N transponders (B.sub.1 . . . B.sub.i . . . B.sub.N).A fixed acoustic transmitting means (E) periodically transmits acoustic pulses at frequency f. The responses of the transponders (B.sub.1 . . . B.sub.i . . . B.sub.N) are received by the acoustic array (A.sub.1, A.sub.2) of the vessels. The time origins are transmitted by a radio antenna to the surface vessel. In the case of submarines, two stable clocks are used, one of which is on board the submarine. Processing circuits make it possible to know the position of submarines.Application to the positioning of vessels in an oil production field or for oceanographic research.

摘要： A graphic position-determining system incorporating two Sell-type transducers that generate acoustic shockwaves and receive their reflections from a surface whose position is to be determined and from fixed calibration reflectors positioned at known distances from the transducers. The design of the transducer includes plastic microspheres between a metalized membrane and a back-electrode to improve the sensitivity, the back-electrode having non-parallel surfaces to reduce unwanted vibrations and permit rapid damping. Apparatus is illustrated for determining the position of a movable cursor and for the verification or transmission of handwriting.

摘要： A system for determining X and Y coordinate positions on a surface wherein a first transducer generates plane waves having electromagnetic fields associated therewith, which plane waves travel along the direction of the X-coordinate and a second transducer generates plane waves having electromagnetic fields associated therewith, which plane waves travel along the direction of the Y-coordinate. A receiver transducer at the position to be determined detects the presence of the electromagnetic fields associated with the plane waves as they travel past the receiver transducer and the distances traveled by the plane waves are appropriately calculated either by determining the times of travel using pulse wave signals or by determining phase relationships using continuous wave signals.

摘要： The present disclosure relates to an acoustic position determination system that includes a mobile communication device and at least one base transmitter unit. The mobile communication device is configured to transmit and receive acoustic signals. Due to relative movements between the mobile communication device and the base transmitter unit, frequencies of the received signals shift due to Doppler effect. The mobile communication device is configured to compensate Doppler frequency shifts in the received acoustic signals prior to performing a deconvolution decoding process. The mobile communication device is further configured to compensate Doppler frequency shifts and perform deconvolution decoding process on acoustic signals received from multiple signal transmission paths.

摘要： A method and apparatus for monitoring a structure using an optical fiber based distributed acoustic sensor (DAS) extending along the length of the structure. The DAS is able to resolve a separate acoustic signal with a spatial resolution of 1 m along the length of the fibre, and hence is able to operate with an acoustic positioning system to determine the position of the riser with the same spatial resolution. In addition, the fiber can at the same time also detect much lower frequency mechanical vibrations in the riser, for example such as resonant mode vibrations induced by movement in the surrounding medium. By using vibration detection in combination with acoustic positioning then overall structure shape monitoring can be undertaken, which is useful for vortex induced vibration (VIV) visualisation, fatigue analysis, and a variety of other advanced purposes. The structure may be a sub-sea riser.
