Abstract: Ultrasensitive, decoupled thermodynamic sensing platforms for the molecular-level detection of target analytes are disclosed, wherein the sensors have a heating resistor decoupled from a sensing resistor. Embodiments of the decoupled sensor comprise a metallic microheater resistor on one side of substrate, and a sensor resistor coupled to a catalyst on the other side of the substrate. A sensor array may be provided including a plurality of sensors each having a different catalyst that, when exposed to an analyte, each experience an endothermic reaction, an exothermic reaction, or no reaction. A comparison of the reaction results to data comprising previously obtained reaction results may be used to determine the presence and the identity of the analyte. Advantageously, the decoupled sensors utilize less power and provide greater sensitivity than other-known systems, and may be used to detect and identify a single molecule of an analyte.

Abstract: The methods and instrumentations for measuring in real-time the two-phase mass flow rate and the enthalpy from the geothermal wells and large diameter pipelines can be used in memory and on-line to measure the mass flow rate and enthalpy when the two-phase pipeline is in operation or during testing. This measuring instrument consists of primary, secondary and multi-tapping components. The primary component can be a concentric orifice plate, a top eccentric orifice plate, a bottom eccentric orifice plate, a segmental orifice plate, Nozzle or Venturi tube. The secondary component is a transmitters-transducers. The multi tapping used are radius (ID and ID/2), flanges, corners and other arrangement or different combinations. On this device system, the data signal of upstream pressure, downstream and the pressure difference of the multi tapping is recorded and transmitted or recorded by the transmitters-transducers to the computer machine.

Abstract: The present disclosure relates to a performance forecasting method applied to an air conditioning equipment and a central server. The air conditioning equipment has a plurality of detecting elements so as to detect a plurality kinds of physical parameters and a performance parameter. The central server stores those parameters as a set of first parameters and a first performance value. When the central server receives other physical parameters and another performance parameter, it calculates the similarity between the other physical parameters and each set of the first parameters according to the law of cosines. The central server selects the set of the first parameters which have the similarity being greater than a selecting threshold, so as to calculating an expected performance value. Accordingly, the central server can forecast a performance decline degree by comparing the another performance parameter and the expected performance value.

Abstract: A heating value derivation device and a heating value derivation method. A gas meter as a heating value derivation device includes a sound velocity derivation unit configured to derive a sound velocity of a gas flowing through a gas flow path, a heating value derivation unit configured to refer to correspondence relationship information that enables a heating value per unit volume to be uniquely derived from the sound velocity of the gas, to thereby derive the heating value per unit volume of the gas, which is independent of a type of the gas, based on the sound velocity derived by the sound velocity derivation unit, and a flow rate derivation unit configured to derive a flow rate of the gas that has passed through the gas flow path. Thus, a passage heating value of the gas can be derived.

Abstract: Downhole fluid sensing device is disclosed for determining heat capacity of a formation fluid produced by a sampled subterranean well, the sensor package having an annulus shaped, elongate body defining a cylindrical fluid sampling space, the sensor package and the sampling space having a common longitudinal center axis. The elongate sensor package body has a fluid entrance port that provides well fluid ingress into the fluid sampling space and a fluid exit port that provides well fluid egress out of the fluid sampling space. A heat source is coupled to the elongate sensor package body and located along a portion of the fluid path, and the heat source inputs heat into sampled well fluid. Finally, temperature sensing devices (located between the fluid entrance port and fluid exit port measure heat conducted to the sampled well fluid, wherein each of the temperature sensing devices is radially spaced from the heat source.
