摘要： A broadband waveguide (10) incorporates various reflection suppression techniques to reduce reflections in signals communicated thereby. The waveguide includes one or more filaments (12) that each include a first and second end (14, 16). A first matrix (18) may be configured proximate the first end(s) while a second matrix (20) may be configured proximate an intermediate location between the first and second ends. A damping material (22b) may cover a portion of the filament(s) that extends from the second matrix to the second end(s) (including the second end(s) themselves) and/or the second end(s) of the filament(s) is/are shaped to at least partially suppress reflections of the signal therefrom. When configured with multiple filaments, at least two of the filaments may have differing lengths that extend from the second matrix and also operate to at least partially suppress reflections of a signal.

摘要： A composite active waveguide temperature sensor (10) incorporates a first, sensor portion (16) formed of an environment-resistant material such as ceramic coupled through an ultrasonically-transparent bond (20) to a second, waveguide portion (18) formed of an ultrasonically-transmissive material such as a metallic filament wire. By doing so, the sensor portion (16) may be positioned within a harsh environment and subjected to a temperature to be measured, and the waveguide portion (18) may be used to propagate ultrasonic energy to and/or from the sensor portion (16) to a location distal from the harsh environment for measurement of the temperature. The ultrasonically-transparent bond (20) between these portions (16, 18) limits attenuation of and the introduction of reflections and other noise to an ultrasonic signal propagated across the bond (20).

摘要： An environmental condition may be measured with a sensor (10) including a wire (20) having an ultrasonic signal transmission characteristic that varies in response to the environmental condition by sensing ultrasonic energy propagated through the wire using multiple types of propagation, and separating an effect of temperature on the wire from an effect of strain on the wire using the sensed ultrasonic energy propagated through the wire using the multiple types of propagation. A positive feedback loop may be used to excite the wire such that strain in the wire is based upon a sensed resonant frequency, while a square wave with a controlled duty cycle may be used to excite the wire at multiple excitation frequencies. A phase matched cone (200, 210) may be used to couple ultrasonic energy between a waveguide wire (202, 212) and a transducer (204, 214).
