    Abstract: A gas sensor comprises at least one transducer and a sensing material (e.g., a metal-organic framework) disposed on the transducer. The sensing material has a temperature-dependent gas sorption behavior. A detector is arranged to detect responses of the transducer to sorption and/or desorption of a target gas in the sensing material and to output transducer measurement signals indicative of the transducer responses. At least one thermal element changes the temperature of the sensing material by heating and/or cooling, and at least one temperature sensor (which may be integral with the thermal element) is arranged to measure a temperature of the sensing material. At least one processor determines the quantity (e.g., concentration, partial pressure, or mass) of the target gas according to the temperature of the sensing material at which the transducer measurement signals satisfy a signal value condition.

  • Patent number: 10458953
    Abstract: A method and a system for acquiring the natural frequency of a diaphragm, wherein, the method comprises: selecting test frequency points in a closed space, converting an electric signal into an acoustic signal, directing sound into the closed space, and acquiring the acoustic pressure of each test frequency point; adjusting the electric signal until the acoustic pressure of each test frequency point is the same; converting the adjusted electric signal into an acoustic signal; acquiring the displacement generated by the vibration of the diaphragm; and taking the frequency corresponding to the maximum displacement of the diaphragm as the natural frequency of the diaphragm. By adopting the method and system, the natural frequency of the diaphragm is determined by acquiring the maximum displacement of the diaphragm. Moreover, the process of acquiring the natural frequency of the diaphragm is not affected by surrounding environment, and therefore the acquired result is more accurate.

    Abstract: The present disclosure provides methods and mechanisms for measuring small masses attached to a substrate within a microcantilever. Specifically, the disclosure describes the measurement of small particles accumulated at a substrate that cannot be flowed through a microchannel within a microcantilever. A resonance measurement is acquired at a first time. A pair resonance measurements is then acquired at a second point in time—one with the test mass at a first position off or along the microcantilever, the second with the test mass at a second position along the microcantilever. Comparing the resonance frequencies determined for the two test mass positions allows for disambiguation of changes in the mass of the particles from changes in the resonant behavior of the microcantilever itself.

  • Publication number: 20150059442
    Abstract: In the present invention a controllable acoustic source (14) in connection with the process fluid (10) emits a signal (18) into the fluid (10), consisting of a suspension of particles (12), being volumes of gas, liquid or solid phase. The controllable acoustic signal (18) is allowed to interact, with the particles (12), and the acoustic (pressure) signals (22) resulting from such an interaction is measured preferably via a sensor (24). A spectrum is measured. The spectrum is used to predict properties, content and/or size of the particles (12) and/or used to control a process in which the process fluid (10) participates. The prediction is performed in the view of the control of the acoustic source (14). The used acoustic signal has preferably a frequency below 20 kHz.

  • Publication number: 20140338423
    Abstract: An acoustic sensor includes a side wall, closed at each end by an end wall, to form a substantially cylindrical cavity, a transmitter and a receiver operatively associated with first and second respective end walls. Properties of the relative dimensions of the cavity are configured to create a desired oscillatory motion of the end walls, and oscillations of a fluid pressure in the cavity, to generate an electrical signal via the receiver to be output from the sensor. An array of acoustic sensors can be connected to allow calibration of one of the array of sensors.

  • Publication number: 20140318218
    Abstract: A method and apparatus of determining gas transport time from an input port to first and second ultrasonic detectors in a flow conduit for an aspirated smoke detector includes first measuring transit time of ambient air between the detectors. Then a different gas is injected into the conduit and the time of injection is stored. The transit time is measured at least intermittently between the two ultrasonic detectors until a change therein is detected. A time of detected change is subtracted from the time of injection to establish a transport time for the aspirated smoke detector.

  • Patent number: 8826724
    Abstract: Chemical sensors such as carbon dioxide sensors and methods for making such sensors are disclosed. An example carbon dioxide sensor may include a substrate, with a sensing beam supported by the substrate. The sensing beam may be configured to resonant. A sensing layer may be disposed on the sensing beam, wherein the sensing layer may include an amino group and is configured to sense carbon dioxide. In some instances, a reference beam may also be supported by the substrate, and may be configured to resonant. A reference layer may be disposed on the reference beam, wherein the reference layer may includes an amino group that has been poisoned so that it will be substantially non-sensitive to carbon dioxide.

  • Publication number: 20140223992
    Abstract: An apparatus and method estimate fluid mass in a cryogenic tank that holds a multiphase fluid comprising a liquid and a vapor. The apparatus comprises a level sensor, a pressure sensor and a computer. The level sensor provides a parameter representative of a level of the liquid. The pressure sensor provides a pressure signal representative of vapor pressure inside the cryogenic tank. The computer is operatively connected with the level sensor and the pressure sensor to receive the parameter and the pressure signal, and is programmed to determine the level from inputs comprising the parameter, to calculate a first volume of the liquid from inputs comprising the level, and to calculate a first mass of the liquid from inputs comprising the first volume and the pressure signal.

  • Patent number: 8763442
    Abstract: In representative embodiments, a system includes an acoustic emitter, a controller, an optical sensor, and an indicator for indicating a detection of a predetermined trace chemical vapor by the optical sensor. The acoustic emitter is positioned at a predetermined distance above the ground surface and configured to project a beam of acoustic energy toward the ground surface with a variable angle of incidence ?. The controller is configured to control the acoustic emitter to vary the angle of incidence of the acoustic beam within the variable angle of incidence ?, while the optical sensor is configured for standoff sensing of a trace chemical vapor proximate the ground surface. Excitation of the ground surface, particularly at a critical angle of incidence ?, causes the release of trace chemical vapors from a buried source and the soil into the air above the buried source.

  • Publication number: 20140154811
    Abstract: Technologies are generally described for gas filtration and detection devices. Example devices may include a graphene membrane and a sensing device. The graphene membrane may be perforated with a plurality of discrete pores having a size-selective to enable one or more molecules to pass through the pores. A sensing device may be attached to a supporting permeable substrate and coupled with the graphene membrane. A fluid mixture including two or more molecules may be exposed to the graphene membrane. Molecules having a smaller diameter than the discrete pores may be directed through the graphene pores, and may be detected by the sensing device. Molecules having a larger size than the discrete pores may be prevented from crossing the graphene membrane. The sensing device may be configured to identify a presence of a selected molecule within the mixture without interference from contaminating factors.
