摘要： The invention is concerned with a method and apparatus for real time analysis of gas mixtures, e g determination of air quality, including at least one resonator (1, 11), means for gas transportation to and from the resonator (1, 11), e g by diffusion or transit flow via openings (5) means for activation (2) and detection (3) of an acoustic signal within the resonator (1, 11), at least one means (7) for measurement of the temperature within the resonator (1, 11), and at least one means (4) for the determination of both the resonance frequency and the quality factor of the resonator (1,11) in real time. These entities are related to the average molecular mass and viscosity or thermal conductivity, respectively, of the gas mixture. The resonator (1, 11 may include a compliant element, e g a constricted volume (6) and an inertial element, e g ist opening (5) or may support standing acoustic waves, in which the sound wavelength is related to a physical dimension of the resonator (1, 11). The determination of resonance frequency and quality factor is preferably based on phase detection within a phase locked loop and is thereby independent of magnitude. In addition to self oscillations at a frequency determined by the resonance frequency, a repetitive frequency modulation is being generated by which a quantity representing the quality factor of the resonator (1, 11) is being generated in real time. Furthermore, means (7) for compensation of temperature or pressure dependence of the resonance frequency or quality factor are included. By an arithmetic-logical unit, e g a microprocessor (9, 17), measured values related to air quality, e g carbon dioxide concentration, relative humidity and temperature are being made available.

摘要： A technique for determining particulate density in a fluid monitors the changes in the speed of sound. Since the speed of sound is intimately related to the composites of the air mixture and since the speed of sound of clean air at any temperature and humidity can be calculated exactly, it is possible to estimate the density of any foreign particulates in the air by observing changes in the speed of sound. Formulations are derived that correlate the change in the speed of sound of the air mixture to their density fluctuations, thus allowing people to estimate the mass density of foreign particulates under any temperature and humidity. Alternatively, the change in density of the air mixture can be detected, thereby indicating the presence of contaminants and a possible alarm, even if the contaminants are not yet identified.

摘要： Embodiments of the present invention generally provide methods, apparatus, and systems for determining void fractions of individual phase components of a multiphase mixture. The void fractions may be determined based on measured parameters of the mixture as a whole, such as differential pressure, bulk velocity of the mixture and speed of sound in the mixture. According to some embodiments, the mixture parameters may be measured using non-intrusive fiber optic based sensors. Various other parameters may also be derived from the void fractions, such as individual phase flow rates, liquid holdup and watercut parameters (for oil and gas mixtures).

摘要： An apparatus and method for screening combinatorial libraries of materials by measuring the response of individual library members to mechanical perturbations is described. The apparatus generally includes a sample holder for containing the library members, an array of probes for mechanically perturbing individual library members, and an array of sensors for measuring the response of each of the library members to the mechanical perturbations. Library members undergoing screening make up a sample array, and individual library members constitute elements of the sample array that are confined to specific locations on the sample holder. During screening, the apparatus mechanically perturbs individual library members by displacing the sample array (sample holder) and the array of probes. Typically, all of the elements of the sample array are perturbed simultaneously, but the apparatus also can also perturb individual or groups of sample array elements sequentially. The flexible apparatus and method can screen libraries of materials based on many different bulk physical properties, including Young's modulus (flexure, uniaxial extension, biaxial compression, and shear); hardness (indentation), failure (stress and strain at failure, toughness), adhesion (tack, loop tack), and flow (viscosity, melt flow indexing, and rheology), among others.

摘要： A device for measuring the specific density of a gaseous or liquid medium (8) having an acoustic transducer (1), which is active on both sides, and further having cylindrical delay paths (4, 5) as well as a ring (6) in which the acoustic transducer (1) is embedded. The diameter of the acoustic transducer (1) is selected such that it is smaller than the diameter of the delay paths (4, 5) so that diffracted waves generated in the area of the edge of the acoustic transducer generate fewer parasitic echoes and surface waves on the boundary surfaces (7, 9) resulting in less corruption of the measured result.

摘要： A system and technique for determining fluid properties includes an ultrasonic transducer 30 on a first surface 42 of a solid member 40. An opposed second surface 44 of the member 40 is in contact with a fluid 25 to be monitored. A longitudinal ultrasonic pulse is delivered through the solid member, and a multiplicity of pulse echoes caused by reflections of the ultrasonic pulse between the solid-fluid interface and the transducer-solid interface are detected and processed by a processing apparatus 22. The apparatus 22 determines the decay rate of the detected echo amplitude as a function of echo number and compares this value to a calibrated decay rate to determine an acoustic property of the fluid. The speed of ultrasound in the fluid is also determined and the fluid density is determined as a function of the speed of ultrasound and the determined acoustic property. When coupled with a shear wave transducer, additional properties corresponding to the fluid viscosity, shear modulus, or shear speed are also determined. Both a fixed in place sensing system and a clamp-on sensing system are disclosed.
