Abstract: In some examples of monitoring pipeline integrity using fiber optics, a first set of values that represent an attenuation of a light signal transmitted through an optical fiber positioned adjacent a pipeline to carry fluids and a second set of values that represent a dispersion of the light signal transmitted through the optical fiber are received. An attenuation profile of the light signal and a dispersion profile of the light signal through the optical fiber are generated based on the first and second sets of values, respectively. Using the profiles, a light-based profile signature describing an environment surrounding the optical fiber is generated, and compared with a baseline light-based profile signature describing an environment surrounding the optical fiber under a normal operating condition. A notification describing an operation of the pipeline is provided in response to the comparing.

Abstract: The present invention provides a magnetic force sensor that can precisely detect and correct variations in a magnetic field generated by a magnetic flux generating source. Therefore, a displacement magneto-electric transducer, which detects a change in the magnetic field caused by an external force, and a fixed magneto-electric transducer, where the change in the magnetic field caused by the external force does not occur, are provided to face end sides of magnetic poles of the magnetic flux generating source. The fixed magneto-electric transducer detects a variation of the magnetic field caused by, for example, changes with time and environmental variations such as a temperature rise in the interior of the sensor. On the basis of a detection amount thereof, an operational section performs a correction operation, so that a sensitivity coefficient or an offset of the displacement magneto-electric transducer is corrected.

Abstract: A capsule comprising two non-directly contacting halves enables otherwise coupling loads between experiment and gauging to be re-routed through the outer-most portable body (e.g. a logging sonde housing) having substantial inertia, thus serving to attenuate the parasitic loads.

Independent bearing sets and shock/vibration isolation support each capsule half within the outer sonde housing. A first half of the capsule supports the experiment, which the second half supports the gauging apparatus.
