  • Patent number: 11985299
    Abstract: A calibration device includes one or more processors. The one or more processors acquire a measured value obtained when a spectroscopic light source configured to output uniform light with a predetermined spectroscopic wavelength and configured to change the spectroscopic wavelength outputs the uniform light while changing the spectroscopic wavelength of the uniform light and a spectroscopic measurement unit to be calibrated spectroscopically measures the outputted uniform light. The one or more processors acquire a target value for each of the spectroscopic wavelengths obtained when the spectroscopic measurement unit measures the uniform light. The one or more processors calculate a transformation matrix for transforming the measured value, based on the measured value and the target value.

  • Patent number: 11982655
    Abstract: The present invention makes it possible to realize an analysis apparatus having a plurality of liquid chromatographs capable of judging separation performance and the like at the right timing and improving analysis performance early. Analysis starts and a mixed sample is prepared by adding a non-retaining ingredient to a measurement object sample and is introduced into an analysis flow path (S401 to S404). The mixed sample is separated into components by a separation column, the components are outputted as chromatogram data by a detector, and the analysis finishes (S404 to S406). Retention time and peak information are acquired from the chromatogram outputted from the detector, whether or not a measurement result is within an allowable range is judged, and the process shifts to next analysis when the measurement result is within the allowable range (S407 to S409).

  • Patent number: 11976954
    Abstract: Introduced herein are a dimensionless relationship between a volumetric flow rate, a head and a kinematic viscosity in a pump operation and a method that uses the dimensionless relationship to predict a viscous performance of a pump from water performance characteristics. Using the introduced dimensionless relationship, which is called Ketan's viscous head number, the introduced method determines a viscous head correlation that allows the prediction of the pump performance to be made accurately at any given speed, flow rate and viscosity. The introduced Ketan's viscous head number and method thus allow a prediction of a pump performance in a viscous application to be made from water performance characteristics without physically testing the pump in the viscous application.

  • Patent number: 11940776
    Abstract: A system is provided that predicts motor wear and failures before they occur. Telemetry data from motors in a motor application is collected and predictive algorithms are used to determine when a motor is aging and when it may fail. Identifying a potential failure in these types of applications can help mitigate risk of other equipment failures and realize cost savings. In one example, a motor aging detection system is provided that includes one or more DC motors, and a motor controller coupled to each motor. The motor controller reads three phase currents from each motor and converts the phase currents to digital values, calculates telemetry data including applied voltages, back electric-motive force, inductance, and resistance of each motor at periodic intervals, stores this telemetry data for each motor in a memory. An age detection circuit retrieves this information from the memory and determines age factors of the motor.

  • Patent number: 11921210
    Abstract: A method for classifying an object in a point cloud includes computing first and second classification statistics for one or more points in the point cloud. Closest matches are determined between the first and second classification statistics and a respective one of a set of first and second classification statistics corresponding to a set of N classes of a respective first and second classifier, to estimate the object is in a respective first and second class. If the first class does not correspond to the second class, a closest fit is performed between the point cloud and model point clouds for only the first and second classes of a third classifier. The object is assigned to the first or second class, based on the closest fit within near real time of receiving the 3D point cloud. A device is operated based on the assigned object class.
