  • Patent number: 10724980
    Abstract: A humidity detector a humidity sensor detecting a relative humidity of an air inside a sensor case housing the humidity sensor. The humidity detector has an air volume obtaining section, a flow direction obtaining section, a setting section, and a correction section. The air volume obtaining section obtains air volume information correlated with an air volume of the air flowing around the humidity sensor. The flow direction obtaining section obtains flow direction information correlated with a flow direction of the air flowing around the humidity sensor. The setting section sets correction factors configuring a dynamic compensator based on the air volume information and the flow direction information. The dynamic compensator compensates for a response delay of the humidity sensor. The correction section corrects a detection value, which is detected by the humidity sensor, by using the dynamic compensator to obtain the relative humidity of the air.

  • Patent number: 10330508
    Abstract: A method of ultrasound flow metering includes applying a first and second pulse train to an ultrasound transducer pair (T1, T2) positioned for coupling ultrasonic waves therebetween. Responsive to the first pulse train applied to T1, T1 transmits an ultrasonic wave received as received ultrasonic wave (R12) by T2 after propagating through fluid in a pipe. Responsive to the second pulse train applied to T2, T2 transmits an ultrasonic wave received as received ultrasonic wave by (R21) T1 after propagating through the fluid. During the pulse trains, R12 and R21 build up in amplitude to provide excitation portions. The pulse trains are terminated, so that R12 and R21 decay as a damped free oscillation. Windowing is applied to R12 and R21 to generate windowed portions. A signal delay between t12 and t21 (?TOF) is calculated using only windowed portions, and a fluid flow is calculated from the ?TOF.

  • Patent number: 9846073
    Abstract: Mass flow controllers with on-tool diagnostic capabilities and methods for on-tool diagnosis of mass flow controllers are disclosed herein. One method includes opening a control valve to a fixed position and closing an upstream valve to produce a flow rate that decreases from a high flow rate, across a range of flow rates, to a low flow rate. A pressure signal is generated that is indicative of a pressure of the fluid within a volume between the upstream valve and a sensor tube, and a flow sensor signal is provided with the mass flow sensor that is indicative of a mass flow rate of the fluid through the main flow path. Ratio curves are produced that relate, across the range of flow rates, a rate of change of the pressure signal to the flow sensor signal and comparing a test ratio curve to a previously generated baseline ratio curve.

  • Patent number: 9726093
    Abstract: In an EGR system, a quantity of exhaust gas passing through an EGR valve is computed by an EGR valve model simulating a behavior of the recirculated exhaust gas passing through the EGR valve. An exhaust gas quantity flowing into a cylinder is computed by an EGR-gas-delay model simulating a behavior of the exhaust gas passing through the EGR valve and the throttle valve and then flows into a cylinder. The EGR-gas-delay model includes a confluent-delay model simulating a behavior of EGR gas passing thorough the EGR valve and flowing into the intake passage upstream of the throttle valve; an intake-pipe-delay model simulating a behavior of EGR gas flowing in the intake passage and passing through the throttle valve; and an intake-manifold-delay model simulating a behavior of EGR gas which passes through the throttle valve and then flows into the intake passage downstream of the throttle valve.

  • Patent number: 9696179
    Abstract: A product may be provided with a product sensor, thus making it possible to determine, together with the product, data relating to a system or a machine with the aid of the product sensor. The data determined can be used to diagnose and/or control the system or machine. In this case, it is advantageous that the data are obtained at the location of the product and it is thus possible to directly determine a desirable or undesirable effect (for example of environmental parameters or of the system itself) on the product. This system can be used, for example, in automation, in systems or machines or in different product manufacture variants.

  • Patent number: 9528914
    Abstract: A non-intrusive sensor system includes an array of sensors disposed in a process to measure various input process phenomena and a logic unit that analyses the sensor measurements using an empirical model to produce an estimate of a further process phenomenon not measured directly by any of the array of sensors. The sensors within the array of sensors may be non-intrusive sensors that measure input process phenomena in an intrusive or non-intrusive manner but are non-intrusive with respect to the output process phenomenon as none of these sensors comes into direct contact with the process fluid or process element exhibiting the output process phenomenon. The sensors within the array of sensors can be any type of sensors that produce a measurement of a particular process phenomenon at the same or at different locations within a process.

  • Patent number: 9465001
    Abstract: A system and method for measuring an electrical characteristic of a fluid using a measuring circuit. In one implementation, the measuring circuit includes a sensing component, a current supply connected to the sensing component, a sensor switchably connected to the sensing component, an array of components switchably connected to the sensing component, and a monitoring circuit connected to the sensing component. A controller performs a calibration of the measuring circuit by switching parallel impedances in and out of the circuit while measuring voltages across the sensing component. The voltages are measured at at least two different phase angles that are determined by the calibration. Once voltages at different impedances and different phases are determined, the controller calculates a value of the electrical characteristic of the fluid by interpolating between lines of fixed capacitance or resistance.

  • Patent number: 9436989
    Abstract: Methods and systems for controlled administration of a tracer and quantification of uptake of the tracer by a target organ are described. The method includes administering a tracer to a patient and imaging at least two regions of the patient's body that cannot be imaged simultaneously. An input function for the tracer can be determined by imaging a first region of the patient's body during selected times, and using an injector to administer the tracer in a manner that accurately estimates the input function when this first region is not being imaged. One or more additional regions of the body may then be imaged to create data that may be used to estimate the input function. One or more parameters may then be estimated from each additional region of the body based on the input function and the imaging data gathered from each region.
