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： 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.

Each of the sensors provides a signal indicative of pressure within the pipe at a corresponding axial and/or circumferential location of the pipe. The sensors are selectively configurable to provide the pressure signals. The signals are processed to determine the parameter. The array of sensors is configurable in response to different criteria. The criteria includes at least one of the parameter of the fluid to be output, an input signal specifying sensors to be selected, a predetermined configuration based on the parameter to be determined, and in response to a previously determined parameter of the fluid.

摘要： An all fiber wavelength selective optical switch has one or more 1.times.N input optical couplers 20,120, each having an input signal with a plurality of wavelengths .lambda..sub.1, .lambda..sub.2, .lambda..sub.3. The output signals from the couplers 20,120 are connected to fibers 26,32,126,158 having Bragg gratings impressed therein, each having a central reflection wavelength, and each having a tuner attached thereto for detuning a central reflection wavelength of the gratings from a base wavelength corresponding to a wavelength of the input signal. For a given grating to pass a particular wavelength of the input signal that grating must be detuned. The fibers 26,32,126,158 are also connected to one or more N.times.1 couplers 66,98 to combine input signals from to different input couplers. The switch allows any combination of input wavelengths from any input signal to be selectively switched to one or more output ports.

摘要： A method for phase biasing a fiber-optic SAGNAC rotation sensor is disclosed comprising the inclusion near one end of the sensing coil of a phase modulator consisting of a second coil of fiber free to rotate independently of the sensing coil. The modulator coil is made to oscillate and the desired phase difference modulation is produced by means of the SAGNAC effect in the oscillating coil. Two novel modulator drivers are disclosed. Both have a rigid support hub having radially extending spokes which bend in mechanical synchronism in response to a piezoelectrically induced motive force. The optical fiber is wrapped like a rim around the outside of the spokes for being rotated in an oscillatory manner to effect the desired phase difference modulation.

摘要： A fiber carrier provides an effective coupling means between a cleaved facing surface of an optical fiber and a light port in a mounting surface of an integrated optical device. Both the fiber carrier and the integrated optical device have an anisotropic thermal expansion property along the same known optic axis and both are substantially similar in magnitude to each other. The fiber carrier is positioned with the integrated optical device so that both the carrier optic axis is parallel to the device optic axis and so that an auxiliary surface of the carrier is parallel to the device mounting surface. The optical fiber is then bonded to the fiber carrier so that the plane of the optical fiber cleaved facing surface lies in the plane of the carrier auxiliary surface. The carrier auxiliary surface is finally bonded to the device mounting surface so that the optical fiber cleaved facing surface is placed in registration with the light port in the device mounting surface.
