摘要: [Object] To provide an arithmetic device, an arithmetic method, and a gas detection system that are capable of easily correcting deterioration over time of a detection element.
[Solving Means] The arithmetic device includes a calculation unit. The calculation unit calculates a correction coefficient from a detection element that causes a resonant frequency change by adsorption of gas on the basis of a resonant frequency change amount associated with a humidity change of the detection element in a degraded state and a resonant frequency change amount associated with a humidity change of the detection element in an initial state that was acquired in advance, and corrects the resonant frequency change amount of the detection element in the degraded state by using the correction coefficient.-

摘要: A method of measuring a pressure of a fluid adjacent a wall of a pipe or vessel. A transducer is attached to the wall of the pipe or vessel. A signal is transmitted by the transducer at a characteristic frequency via a plurality of guided wave modes. The characteristic frequency is a frequency at which the guided wave modes are separated in time from each other when received. The signal is received after the plurality of guided wave modes travel in or through the wall a predetermined number of times. The signal has a signal receipt time after the predetermined number of times. The pressure of the fluid is calculated using the signal receipt time.

摘要: Systems and methods for determining a fill level of a fluid within a fluid vessel, an identity of the fluid, and/or a condition of the vessel wall are disclosed. To determine a fluid fill level, at least one acoustic sensor is positionable substantially on an exterior sidewall of a vessel containing fluid. A computerized device is in communication with the at least one acoustic sensor. A processor of the computerized device receives a detection signal from the at least one acoustic sensor and communicates an alert of the detection signal, which can be used to identify a fill level of the fluid. The detection signal, along with other measured information, can be used to identify the material type of the fluid. A condition of the vessel wall may be determined based on an attenuation signal when two acoustic sensors are used, one being positioned angular to the vessel wall.

摘要: A disruptor adjustment system comprising: a disruptor assembly configured to disrupt a volume of smelt flowing from a smelt spout into a dissolving tank, wherein the disruptor assembly comprises an actuator operatively engaged to a disruptor, a sensor configured to record process data from the recovery boiler; and a control system configured to receive a sensor output signal from the sensor, wherein the sensor output signal indicates the process data at a measured time, wherein the control system is further configured to compare the sensor output signal to a programmed operation range, and to send a disruptor input signal to the disruptor assembly to adjust a disruptor operating condition if the process data of the sensor output signal is outside of the programmed operation range. In certain exemplary embodiments, the sensor is an image capture device. In certain exemplary embodiments, the disruptor assembly can be adjusted remotely.

摘要: A tool for analysis of sound wave propagation in an aquatic medium. The tool generates a model representing the aquatic medium as a three-dimensional (3D) Gaussian random field, the 3D Gaussian random field being described by one or more correlation functions. The tool determines a propagation trajectory of a sound wave in the aquatic medium based on the 3D Gaussian random field.

摘要: A cartridge for sample handling and sensing includes a sample port connected to a sample reservoir having a proximal end, a proximal region adjacent the proximal end, and a distal end opposite of the proximal end. The cartridge also includes a first fluid port connected to the sample reservoir in the distal region via a first fluid channel; and a second fluid port connected to the sample reservoir in the proximal region via a second fluid channel. In addition, the cartridge includes a sensor platform comprising a bulk acoustic wave (BAW) resonator and a fluid flow path comprising a sensing region extending across a sensing surface of the BAW resonator. The cartridge further includes a fluid valve between the distal end of the sample reservoir and the sensing region. A sample may be applied to the sample port; first volume of fluid may be injected through the first fluid port; and then a second volume of fluid may be injected through the second fluid port to drive the sample into the sensing region of the fluid flow path.
