摘要： A tool for detecting leaks in downhole pipe comprises wave generator devices (30, 40) for coupling ultrasound waves into the surrounding fluid. The waves are scattered, e.g. reflected, at inhomogeneities (60) in the fluid, for example particles, scatterers and/or water in oil, thereby generating reflections (70) which are measured with a receiver device (25) and evaluated for determining the positions of the inhomogeneities in the fluid in order to detect e.g. crossflows (15) generated by leakage (65).

摘要： A system and method for location positioning with steganographic encoded data streams in audible-frequency range audio is disclosed. The method comprises encoding, modulating and audio-hiding data streams into corresponding audible-frequency range steganographic audio signal; transmitting each audio signal by a corresponding loudspeaker, wherein each data stream includes the geographic location of the corresponding loudspeaker, a time stamp of transmission of periodic frames of the data stream and the like. In addition, a mobile device is used for: acquiring an audio signal that includes the transmitted audio signals; separating, demodulating and decoding the data streams therefrom; calculating the distance between the mobile device and each of the loudspeakers based on the time of flight between transmission and acquisition of each of the audio signals; and estimating the geographic location of the mobile device based on the distance between the mobile device and the loudspeakers and the geographic location of the loudspeakers.

摘要： A method comprises transmitting (901) a first ultrasonic ping signal from a first floating unit (M1). The first ultrasonic ping signal is received in an underwater device (D1, D2, D3). After a predetermined delay from the reception of the first ultrasonic ping signal, the underwater device transmits (905) a second ultra-sonic ping signal from the underwater device. The second ultrasonic ping signal is received in the first floating unit. The first floating unit determines a time difference between a time of transmission of the first ultrasonic ping signal from the first floating unit and a time of reception of the second ultrasonic ping signal, and based on the time difference, provides location information and/or other information to the underwater device by transmitting (910) to the underwater device sequential underwater ultrasonic ping signals such that time differences between the sequential underwater ultrasonic ping signals indicate the provided information.

摘要： A method for determining the position of an underwater device includes placement of a plurality of station keeping devices on or below the surface of the water in known positions. A device to locate is provided for placement below the surface of the water, and the device to locate and the station keeping devices are provided with a synchronized time base and a common acoustic pulse time schedule. Each station keeping device sends an acoustic pulse at a time according to the common acoustic pulse schedule. The device to locate receives pulses sent by the station keeping devices and calculates a distance between itself and each station keeping device based upon the time that the acoustic pulse is sent and the time that the pulse is received. The device to locate then calculates its position based upon the distances between the device to locate and the station keeping devices.
