  • Publication number: 20250199199
    Abstract: Field calibration of a pressure device involves collecting simultaneous pressure data or pressure and temperature data at two devices for multiple time points. Pressure differences between pairs of simultaneous data points of the collected pressure data are calculated. A model is fitted to the pressure differences and the temperatures and/or pressures, and model parameters are used to correct measurements from the second device. Alternatively, a pressure gradient is estimated for a region that encompasses the two devices for each time point. A distance is determined between the two devices. A pressure gradient difference is determined between the two devices for each time point. A pressure difference offset is obtained for one of the pairs of simultaneous data points for each time point. An average pressure difference offset is determined between the two devices and is used to correct measurements from one of the devices.

  • Publication number: 20250191404
    Abstract: In a facial expression recognition method, facial key points are identified as graph nodes. A facial graph structure for a first image is constructed with edges between pairs of the graph nodes based on relationships between the facial key points corresponding to the graph nodes. A first feature of a facial texture is extracted from color information of pixels in the first image. A second feature of the first image is extracted by processing the facial graph structure using a graph neural network (GNN). The first feature and the second feature are combined, to obtain a fused feature. A first expression type of a face in the first image that corresponds to the fused feature is determined. The first expression type is determined from a plurality of facial expression types.

    Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may perform distribution matching on at least a first subset of a set of bits, such as the bits of transport block. The distribution matching may include a variable-to-fixed (v2f) distribution matching procedure in which a ratio between a quantity of input bits to output interim symbols for the v2f distribution matching procedure is variable. The distribution matching include evaluating, after each instance of the v2f distribution matching procedure, whether additional bits remain for distribution matching, and if so, whether to perform an additional instance of the v2f distribution matching procedure or an alternative distribution matching procedure on the remaining bits. Corresponding techniques for a receiving device are also described, including distribution dematching techniques based on a v2f distribution dematching procedure.
