The application discloses a dielectric waveguide resonator and a multimode dielectric waveguide resonator, which comprises a dielectric resonant cavity, the dielectric resonant cavity comprises a dielectric body and a metal plating layer wrapping an outer surface of the dielectric body; a metal loading interface is arranged in the dielectric body and is connected with the metal plating layer; the metal loading interface intersects with an intrinsic electric field direction of the dielectric resonant cavity to reduce a main mode frequency of the dielectric resonant cavity. Embodiments of the application provide a dielectric waveguide resonator and a multimode dielectric waveguide resonator, by adding a metal loading interface in a dielectric body of a dielectric waveguide resonator, the size, frequency and unloaded Q value of the dielectric waveguide resonator are kept unchanged, high-order mode harmonics are pushed away, the performance of a low-pass filter is improved, and loss is improved.

This utility model relates to the field of electronic device accessories technology, specifically to a tablet keyboard protective cover and a tablet computer assembly. The tablet keyboard protective cover includes: a first sleeve and a second sleeve rotatably connected. The keyboard is connected to the inner side of the first sleeve. The second sleeve includes a first support plate and a second support plate rotatably connected. The first support plate is rotatably connected to the first sleeve via a first flexible connecting part, and a protective shell is connected to the second support plate. A support member is rotatably connected to the side of the keyboard near the first flexible connecting part. The support member is connected to the first support plate via a second flexible connecting part, so that when the tablet keyboard protective cover is closed, the width direction of the support member rotates to be perpendicular to the plane of the keyboard; when the tablet keyboard protective cover is open to support the tablet computer, the width direction of the support member rotates to be parallel to the plane of the keyboard. This method extends the effective support surface during use, which helps to improve the stable support for the tablet computer.

This invention relates to the field of intelligent port safety management technology, and in particular to a port anomaly decision-making system combining video surveillance and a large-scale model. The system includes: a video recognition module that analyzes real-time video streams from the port area to identify changes in the status of personnel, vehicles, and equipment and generate candidate anomaly events; a data access module that acquires operational data from the port's production and equipment systems to form operational status parameters and equipment operating parameters; a risk boundary generation module that dynamically generates a two-dimensional risk area polygon model based on the operational status; a risk prediction module that constructs the future movement path of equipment and a three-dimensional risk envelope through trajectory extrapolation; a decision generation module that integrates anomaly events and risk spatial information and generates structured handling instructions through the large-scale model; and a decision verification module that performs spatial extrapolation and safety verification of the handling instructions in a digital twin environment. This invention achieves collaborative processing of anomaly identification, risk prediction, and decision verification.

The utility model discloses an integrated cabinet body of flywheel converter, and the cabinet body is divided into power area and control area through the partition structure, at least one pull-out box is equipped in the control area, the pull-out box is used for installing the control component and is convenient for pull-out maintenance, the partition structure includes partition frame and the baffle covered and installed on the partition frame, realizes the physical isolation of power area and control area, thereby integrates power area and control area in the same cabinet body, realizes functional isolation through the baffle at the same time, greatly reduces the overall floor area, improves single cabinet space utilization, especially suitable for the scene of higher space compactness requirement such as computer lab, energy storage power station. Through the setting of pull-out box, it is convenient to directly pull out the cabinet operation, does not need to dismount fixed bolt or removes the periphery component as a whole, and maintenance time is shortened.
