6results about How to "Reduce structural redundancy" patented technology

This invention discloses a sewing machine thread handling device and sewing equipment, relating to the field of sewing equipment technology. To address the problems of functional dispersion, structural redundancy, and low space utilization in existing technologies where the thread clamping and thread end collection structures are inefficient, this device includes a needle plate, a thread gripping assembly, and a thread clamping and suction assembly. Both the thread gripping assembly and the thread clamping and suction assembly are located on the needle plate. The thread gripping assembly includes a thread gripping component, and the thread clamping and suction assembly includes a thread clamping part and a suction channel. The thread gripping component and the thread clamping part are arranged opposite to each other to form a thread clamping area for gripping the thread. The suction inlet of the suction channel faces the thread clamping area. This arrangement ensures effective thread clamping while simultaneously collecting thread ends, effectively reducing the number of functional components, simplifying the device structure, and improving space utilization. It also allows thread ends to be immediately sucked in after being removed from the clamp, reducing the risk of thread residue and accumulation, and improving thread end processing efficiency and equipment operational reliability.

This application provides an LSTM inference method and electronic device based on channel pruning and gating configuration, belonging to the field of LSTM state computation technology. The method includes: acquiring a GNSS input signal; determining the current task category and its state complexity level based on the characteristic fluctuation range and historical state of the GNSS input signal; pruning hidden state channels according to the current task category and its state complexity level, based on a pruning strategy selected from a task channel pruning strategy library, and configuring gating paths based on an LSTM gating configuration table; and performing LSTM inference corresponding to the current task based on the pruned hidden state channels and the configured gating paths. This application's solution can reduce redundancy in multi-task LSTM structures.

This utility model discloses a pressure plate type dynamic balancing ring for large disc cutters, including a tool holder, a balance seat, and a clamping screw that are fitted together. The tool holder, balance seat, and clamping screw are coaxially arranged. The balance seat is disc-shaped and has several counterweight mounting holes arranged in a circular array. The circular array of counterweight mounting holes forms a set of counterweight adjustment structures. The counterweight adjustment structures are concentric with the balance seat, and the axial direction of the balance seat is the same as the axial direction of the counterweight mounting holes. This utility model has both pressure plate and dynamic balancing adjustment functions, reducing structural redundancy. It also allows for the replacement of balance seats of different volumes to accommodate different sizes of large disc cutters, making it more adaptable. Furthermore, it significantly reduces the risk of counterweights flying off, further reducing safety hazards.
