Page processing methods, devices, electronic devices, storage media, and products

This invention discloses a page processing method, apparatus, electronic device, storage medium, and product. The method includes: responding to a page interaction operation performed on a browser page; identifying at least one page interaction operation event triggered on the browser page through a pre-configured browser plugin and determining the voice content associated with the at least one page interaction operation event, wherein the voice content associated with the page interaction operation event is voice material related to the page interaction operation formed by synchronously providing voice explanation of the page interaction operation performed on the browser page; determining the DOM element positioning information corresponding to the at least one page interaction operation event; generating a target document based on the voice content associated with the page interaction operation event; and generating a target script based on the DOM element positioning information corresponding to the at least one page interaction operation event and the triggering order of the at least one page interaction operation event. This application solves the problem of low efficiency due to repetitive configuration during browser page configuration.

A handrail welding fixture

ActiveCN121715787BImprove welding positioning accuracyaccurate location
This invention belongs to the field of welding fixtures and provides a handrail welding fixture, including: a fixture table; a positioning mechanism, an anti-detachment mechanism, and an auxiliary mechanism. The auxiliary mechanism includes a reference block, a first positioning bead, and a second positioning bead. On the reference block, a first reference surface is provided on the side opposite to the first positioning bead, and a second reference surface is provided on the side opposite to the second positioning bead. Both the first and second positioning beads are movably disposed within the reference block and can abut against the inner wall of a reference hole. Compared with the prior art, the advantage of this invention is that by using a single driving source to drive the first and second positioning beads against the inner wall of the reference hole, the first and second positioning surfaces are precisely fitted with the first and second reference surfaces, respectively. This ensures that the fixed block is accurately positioned and without deviation during welding, avoiding the impact of the reference block's own processing errors on the overall positioning accuracy of the fixed block. This significantly improves the welding positioning accuracy of the handrail and ensures consistent product quality.

A Method and System for Optimizing LiDAR Odometry Based on Resource Utilization Costs

ActiveCN121858304BGuaranteed uptimeavoid positioning failureImage analysisWave based measurement systemsOdometryPoint cloud
This invention belongs to the field of lidar odometry technology and provides a lidar odometry optimization method and system based on resource occupancy cost. Based on raw point cloud data and preset geometric feature algorithms, general feature algorithms, and direct registration algorithms, corresponding candidate poses and feature matching errors are obtained respectively. Based on CPU utilization, memory utilization, cache hit rate, and a preset resource occupancy cost model, the total resource occupancy cost is obtained. Based on the candidate pose, feature matching error, and total resource occupancy cost, the optimal pose estimation is determined with the minimum total cost as the optimization objective. By introducing the resource occupancy cost model, resource efficiency is taken as one of the core optimization objectives, enabling the odometry to dynamically adjust the algorithm strategy according to the current system load. This pursues high accuracy when resources are abundant and ensures smooth system operation when resources are limited, effectively avoiding positioning failures caused by computational overload.

PendingCN122275011AAvoid timing alignment issueslow costRobot handControl engineering
This application relates to the field of intelligent manufacturing equipment technology, and in particular to a high-precision path control method for injection molding robots based on real-time deviation compensation. The method includes: acquiring the theoretical position commands and actual encoder feedback values ​​of each servo axis within the same control cycle via a CANopen bus under clock synchronization reference, and calculating the single-axis deviation; constructing a historical sequence of deviations from multiple consecutive cycles, and predicting the deviation for the next cycle using a fixed-order autoregressive model; subtracting the predicted deviation from the theoretical command after multiplying it by the compensation gain to obtain a preliminary correction command; constructing a dynamic safety envelope with constraints such as the in-mold safety zone, the out-of-mold safety zone, and the minimum safety distance between multiple axes, and performing real-time verification and limiting of the preliminary correction command; and sending the correction command to the servo driver. This application achieves high-precision path tracking and active anti-collision control for injection molding robots in high-speed, confined mold spaces, improving repeatability and operational safety.
