A test apparatus and method for testing the cold bending limit failure of glass

This invention relates to the field of glass production testing technology, specifically disclosing a glass cold bending ultimate failure test device and method. The device includes a worktable and four identical cold bending loading units. Each unit integrates a planar displacement structure with horizontal displacement capability, a liftable and directional adjustable support structure, and a pressure head connected by a ball joint. During testing, the planar displacement structure of each unit is first adjusted to accommodate glass specimens of different sizes. Then, the support structures of three units form an L-shaped support surface, and their pressure heads press against corresponding corner points on the upper part of the specimen to establish stable constraints. Finally, the pressure head of the fourth unit applies a concentrated load to the unconstrained corner points, while automatically monitoring the load and displacement until the specimen fails. This invention, through modular and automated design, achieves high versatility of the device, high testing accuracy, and high operational safety, effectively improving testing efficiency and data reliability.

Three-dimensional human body model fitting method based on two-dimensional contour interaction and semantic segmentation

PendingCN122089953AUnderstand and predict joint space relationshipsAccurate understandingInternal combustion piston enginesBiological modelsPattern recognitionHuman body
This invention discloses a method for fitting a 3D human body model based on 2D contour interaction and semantic segmentation. The method first parses a user-drawn 2D stick figure skeleton using a JPN module and drives an SMSLX model to generate an initial 3D human body. Then, the initial model contour is rendered from multiple fixed perspectives, generating corresponding bounding voxel spaces and point cloud projections. A prior network combining UDF and positional information is introduced to guide the training of the multi-view semantic segmentation network module UPS, achieving accurate segmentation of each part of the contour image. Based on the segmentation results and voxel point cloud projections, surface constraint point clouds for each body part are calculated. Finally, using the constraint point clouds as targets, the SMSLX model parameters are optimized for each part using a CFM module, ultimately generating a 3D human body shape that matches the user's editing intent. This invention allows users to indirectly adjust complex 3D models through intuitive 2D contour editing, significantly improving interaction efficiency and avoiding direct manipulation of complex 3D data.

The application discloses a pet emotion electroencephalogram signal extraction algorithm, and belongs to the field of electroencephalogram signal processing. In view of the spatial asymmetric interference caused by pet activity and the nonlinear artifact caused by contact impedance mutation, bilateral baseline and forehead electroencephalogram signals of the pet are synchronously collected and processed as follows. First, one side of the baseline is used to cross-space predict the other side, and asymmetric residual error isolated from local noise is extracted; second, a delay autocorrelation prediction is performed on the main signal of the forehead, and low-frequency physiological drift is accurately stripped; finally, the residual error and the main error signal are sent into a second-order Volterra network for spatial mapping, so as to offset the nonlinear coupling interference. The application effectively blocks the common-mode diffusion of unilateral noise, realizes deep decoupling of physiological drift and neural potential, and can still restore the pet electroencephalogram characteristics with high fidelity under violent movement.
