摘要： A lubricity sensor includes a flexural plate wave device and a face shear mode bulk acoustic wave device, which is associated with and located proximate to the flexural plate wave device. The face shear mode bulk acoustic wave device and the flexural plate wave device form a lubricity sensor wherein acoustic wave data produced by the flexural plate device together with the face shear mode bulk acoustic wave device when the lubricity sensor is exposed to a liquid relates directly to a lubricity of the liquid thereby providing lubricity measurement data associated with the liquid. The acoustic wave data can comprises the oscillation gain compensation, the frequency, amplitude and/or phase velocity associated with the flexural plate device and the shear mode bulk acoustic wave device such that the oscillation gain compensation, the frequency, amplitude and/or phase velocity provide an indication of the lubricity of the liquid.

摘要： A system and method for determining the atomization characteristics of fluids being emitted by a nozzle is disclosed. In one embodiment, a fluid is emitted through a nozzle while simultaneously sensing vibrations occurring within the nozzle. The vibrations provide information about the atomization characteristics of the fluid. By comparing the sensed vibrations to vibration patterns produced by known fluids through the same or a similar nozzle, the atomization characteristics of the fluid being tested can be predicted. In one embodiment, for instance, the atomization characteristics of a fluid may be determined as a function of velocity or flow rate through the nozzle.

摘要： Ultrasonic apparatus and associated methods for the in-line monitoring of melting, mixing and chemical reaction processes of materials inside an enclosed chamber having rotating elements associated therewith are presented. The chamber may be heated and the rotating elements may be blades and/or screws. The chamber may be a heating barrel and the materials may be polymer and polymer composites pellets, metal pellets and chemical compounds. Ultrasonic sensors, which are preferably coupled to a wall of the chamber, may be high temperature ultrasonic transducers attached to the external surface of the chamber or ultrasonic buffer rods embedded into the chamber and coupled to cooled ultrasonic transducers. These sensors are operated in the reflection mode and are placed over the rotating elements. The number and locations of the sensors depend on applications. The synchronization of the transmission of the ultrasonic signals and the associated data acquisition with the position of the rotating element may be accomplished by using a high speed multiple-record data acquisition system. The ultrasonic speed and attenuation in the material being processed, or the traveling time in the material and the amplitude of the ultrasonic signals reflected by the rotating element, the ultrasonic reflection coefficient or the amplitude of the ultrasonic signals reflected at the chamber-material interface or the buffer rod probing end-material interface, and the ultrasonic signals scattered by the material within the chamber, can provide information on the melting, mixing and chemical reaction of the materials.

摘要： A fermention process is monitored by detecting ultrasound backscattered from the cells as a function of time. A transducer 46 is placed in a fermentor 30 and transmits ultrasound towards a reflecting surface 50. The transducer receives that portion of the ultrasound which reflects from the reflecting surface 50, as well as that portion of the ultrasound which backscatters from cells 34 between the transducer 46 and the reflecting surface 50. Signals from the transducer are conditioned and subsequently processed to provide output to a controller regarding the status of the fermentation process in real time. The backscattering measurements can be used to determine a growth phase transition, such as the transition between the logarithmic growth phase of the cells and their stationary phase.

摘要： A gas-concentration measuring apparatus for measuring the concentration variation of gas residing in a target region The gas-concentration measuring apparatus comprises an ultrasound-transmitter adapted to transmit an ultrasound in response to an ultrasound-generating signal having a rate of voltage change equal to or greater than a slew rate of an operational amplifier, and further adapted to output the ultrasound-generating signal. An ultrasound-receiver adapted to receive the ultrasound passed through the gas residing in the target region, and further adapted to convert the received ultrasound into an electrical signal serving as a received ultrasound signal is provided. A gas-concentration determiner adapted to input the ultrasound-generating signal and the received ultrasound signal into the operational amplifier to generate an amplified transmitting-side chopping wave and an amplified receiving-side chopping wave is further provided. The gas-concentration determiner is further adapted to compare the transmitting-side and receiving-side chopping waves independently with corresponding given threshold voltages to detect a first pair of time points when the respective chopping waves become equal to or greater than the corresponding given threshold voltages or to detect a second pair of time points when the respective chopping waves become equal to or less than the corresponding given threshold voltages. The gas-concentration determiner is further adapted to determine the concentration variation in the gas based on the pair of time points.

摘要： A gas sensor includes an element case 42 with an internal peripheral surface formed as a taper surface 100. A portion of a housing section 43 surrounded by the taper surface 100 and a protective film 48 is filled with a filler 49. When the filler 49 thermally expands at high temperature, the filler 49 is subjected to a component of force in an upward direction by the taper surface 100. Therefore, projection of an element portion 44 involving deformation of the protective film 48 is suppressed, a change nullL of a propagation distance L to a reflecting section 33 is also suppressed, and a detection accuracy never decreases. In addition, reverberation is reduced.
