摘要： Embodiments of a kernel-level grain monitoring system include a grain camera positioned to capture bulk grain sample images of a currently-harvested grain taken into and processed by a combine harvester, a moisture sensor, and a display device. A controller architecture is coupled to the grain camera, to the moisture sensor, and to the display device. The controller architecture is configured to: (i) analyze the bulk grain sample images, as received from the grain camera, to determine an average per kernel (APK) volume representing an estimated volume of a single average kernel of the currently-harvested grain; (ii) repeatedly calculate one or more topline harvesting parameters based, at least in part, on the determined APK volume and the moisture sensor data; and (iii) selectively present the topline harvesting parameters on the display device for viewing by an operator of the combine harvester.

摘要： A cotton harvester estimates the mass of cotton as it is harvested using sensor devices and compares the mass of each module against the estimated mass of the module as determined by the sensors so that a calibration factor may be determined and actively updated for more accurate crop yield determination. The mass flow for a specific module is accumulated and processed during harvesting using a base calibration factor and the module is weighed and compared against the expected mass using the base calibration factor to develop a candidate updated calibration factor. The base calibration factor is selectively replaced by the candidate updated calibration factor for processing a subsequent module based on machine feedback information relating to the operation of the harvester. Harvested crop data determined using the calibration factor is used to generate highly accurate yield maps.

摘要： A system for removing dead volume in a sensor assembly of a mass flow controller is presented. The system comprises a valve assembly communicable coupled to the sensor assembly. The valve assembly is in fluid communication with fluid in a primary flow path and the sensor assembly is in fluid communication with fluid in the primary flow path. The sensor assembly comprises a pressure transducer having a first reservoir and another pressure transducer having a second reservoir. The first reservoir has a port in fluid communication with fluid in a sampled flow path. The second reservoir is coupled to a second pressure transducer and is fluidly coupled to the first reservoir through a flow through path. The second reservoir also includes another port for communicating the flow of fluid from the flow through path to another flow path. A flow rate restrictor is disposed in the flow through path.

摘要： Method and system for determining a specific mass flow rate of a highly viscous food product (1) having a viscosity of greater than 100 cP, which during processing in a continuous delivery flow is supplied to or removed from a buffer container (2) by means of a delivery pump (4), wherein a weighing device (7) is used to determine the change in the mass of the food product (1) in the buffer container (2) over a defined time period, which is in particular in the range of one or several minutes (Δm/Δt), wherein, in the same time period a pump parameter of the delivery pump (4) that is proportional to the expected delivery rate is registered, changes in the pump parameter over the time period are averaged to form an average pump parameter, wherein the current specific mass flow rate is calculated as a quotient from the change over time of the mass Δm/Δt and the averaged pump parameter and is output.

摘要： A device (1) for determining the mass flow rate of milk turbulently flowing with air in a pipe (2) in pulsed milk slugs comprises sampling a signal from a microphone (8) of the device (1) indicative of sonic signals produced by the milk flow. The sampled signals are read by a microprocessor (15) which applies a Fast Fourier Transform to the sampled signal to produce the frequency domain of the sampled signal. The microprocessor (15) is configured to compute the average energy value of the sampled signal in the frequency bandwidth of 6 kHz to 15 kHz during consecutive monitoring periods. The average energy values are inserted into a calibration equation, which may be a power law equation, a polynomial equation, a logarithmic equation or any other such suitable equation in order to convert the average energy value to a mass flow rate of the milk flowing through the pipe 2 during that predefined monitoring period. The total mass flow of milk flowing through the pipeline (2) during a period from T1 to T2 is determined by integrating the determined mass flow rate of the milk from the time T1 to the time T2. Disengagement of a milking cluster from the teats of an animal as a result of kick-off during milking is also determined when the monitored signal from the microphone (8) transitions from the signal indicative of milk flowing in pulsed slugs to a continuous relatively high energy noise signal indicative of air being continuously drawn through the pipeline.

摘要： Apparatus and methods for rapidly detecting, localizing, imaging, and quantifying leaks of natural gas and other hydrocarbon and greenhouse gases. Scanning sensors, scan patterns, and data processing algorithms enable monitoring a site to rapidly detect, localize, image, and quantify amounts and rates of hydrocarbon leaks. Multispectral short-wave infrared detectors sense non-thermal infrared radiation from natural solar or artificial illumination sources by differential absorption spectroscopy. A multispectral sensor is scanned to envelop an area of interest, detect the presence and location of a leak, and raster scan the area around the leak to create an image of the leak. The resulting absorption image related to differential spectral optical depth is color mapped to render the degree of gas absorption across the scene. Analysis of this optical depth image, with factors including known inline pressures and/or surface wind speed measurements, enable estimation of the leak rate, i.e., emission mass flux of gas.
