摘要： A creep-resistant optical fiber attachment includes an optical fiber 10, having a cladding 12 and a core 14, having a variation region 16 (expanded or recessed) of an outer dimension on of the cladding and a structure, such as a ferrule 30, disposed against least a portion of the variation region 16. The fiber 10 is held in tension against the ferrule and the ferrule 30 has a size and shape that mechanically locks the ferrule 30 to the variation 16, thereby holding the fiber 10 in tension against the ferrule 30 with minimal relative movement (or creep) in at least one axail direction between the fiber 10 and the ferrule 30. The ferrule 30 may be attached to or part of a larger structure, such as a housing. The variation 16 and the ferrule 30 may have various different shapes and sizes. There may also be a buffer layer 18 between the cladding 12 and the ferrule 30 to protect the fiber 10 and/or to help secure the ferrule 30 to the fiber 10 to minimize creep.

摘要： The present invention provides new techniques for non-invasive and real-time measurement of the velocity profile of slurry flow in horizontal pipes, as well as the measurement and trending of pipe wear on slurry lines. In the first case, this information can be used to determine the approach and onset of solid deposition on the bottom of the pipe. Having this information in real time can enable operation at lower velocities or higher solids concentration or both while avoiding solids deposition or plugging and their associated operational costs. In the second case, the present invention uses a permanently or semi-permanently installed ring of conformable ultrasonic transducers clamped onto the outside of the pipe. These transducers are used to measure the thickness of the pipe under their respective locations.

摘要： A method and device for tuning an optical device including an optical fiber having a core, a cladding and a Bragg grating imparted in the core to partially reflect an optical signal at a reflection wavelength characteristic of the spacing of the Bragg grating. The cladding has two variation regions located on opposite sides of the Bragg grating to allow attachment mechanisms to be disposed against the optical fiber. The attachment mechanisms are mounted to a frame so as to allow the spacing of the Bragg grating to be changed by an actuator which tunes the reflection wavelength. In particular, the variation region has a diameter different from the cladding diameter, and the attachment mechanism comprises a ferrule including a front portion having a profile substantially corresponding to diameter of the variation region and a butting mechanism butting the ferrule against the optical fiber.

摘要： A method and device for pressure sensing using an optical fiber having a core, a cladding and a Bragg grating imparted in the core for at least partially reflecting an optical signal at a characteristic wavelength. The cladding has two variation regions located on opposite sides of the Bragg grating to allow attachment mechanisms to be disposed against the optical fiber. The attachment mechanisms are mounted to a pressure sensitive structure so as to allow the characteristic wavelength to change according to pressure in an environment. In particular, the variation region has a diameter different from the cladding diameter, and the attachment mechanism comprises a ferrule including a front portion having a profile substantially corresponding to at least a portion of the diameter of the variation region and a butting mechanism which holds the ferrule against the optical fiber.

摘要： Apparatus features a container and a transducer. The container is made of a selected material and has a container wall with a selected thickness, and configured to hold a fluid therein. The transducer is configured on the outside of the container wall, and is also configured to provide a standing wave into the fluid. The selected thickness and material of the container wall is chosen to ensure about a ½ wavelength of a desired frequency exists within the container wall, so as to substantially reduce back reflections toward the transducer due to any mismatch in acoustic impedance at the interface between the container wall and the fluid, and so as to substantially maximize the amount of energy delivered to the fluid, thus improving the operating efficiency of the apparatus.

摘要： A method and apparatus for measuring a parameter of a flow passing through a pipe is provided, wherein the apparatus includes at least two spatial array of sensors disposed at different axial locations along the pipe, wherein each of the sensors provide a signal indicative of unsteady pressure created by coherent structures convecting with the flow within the pipe at a corresponding axial location of the pipe. The apparatus also includes a signal processor configured to determine the flow rate at the circumference location of each sensor array in response to the respective measured unsteady pressures. The signal processor compares the velocity of the flow at each respective location and provides a signal indicative the presence of solids settled at the bottom of the pipe and/or the level of the settled solids in the pipe, in response to an uncharacteristic increase in the velocity of a lower portion of the flow in comparison to the velocity measured above the lower portion of the flow.
