  • Patent number: 11959934
    Abstract: A high precision weighing system and weighing method has a weighing plate and weighing unit separation mechanism and a weight loading mechanism. The weighing plate and weighing unit separation mechanism controls separation of a weighing plate and a weighing unit, so that the weighing plate or the weighing plate and its carried material do not apply force to the weighing unit. The weight loading mechanism loads a weight onto the weighing unit or removes a weight from the weighing unit; the weighing system records a weighing value of the weighing unit during the action of the weighing plate and weighing unit separation mechanism and a sensitivity value during the action of the weight loading mechanism. The weighing system modifies the weighing value at the time of the most recent combination of the weighing plate and the weighing unit based on the recorded weighing and sensitivity values, achieving a high precision.

  • Publication number: 20240069195
    Abstract: A displacement detector may include a substrate and a membrane having an inner surface facing the substrate. A mounting area may be arranged to fix the membrane along at least part of the perimeter of the membrane, wherein the mounting area, the inner surface and the substrate enclose a back volume. An acoustic compliance of the back volume may be arranged to be the same or larger than an acoustic compliance of the membrane. An optical sensor may be configured to generate a sensor signal indicative of a displacement of the membrane.

  • Patent number: 11748621
    Abstract: An embodiment includes generating an input document that includes a plurality of text fields of attribute data. The embodiment also includes extracting a set of candidate features from the attribute data using a feature extraction module that evaluates the attribute data using first and second machine learning models, where the first machine learning model scores terms in the input document and the second machine learning model includes a deep learning model. The embodiment also includes calculating feature-selection values for respective features of the set of candidate features and generating tag information for a remote computing asset using a machine learning classifier that predicts the tag information based on the feature-selection values.
