This utility model discloses a bedside table with a concealed compartment component, relating to the field of furniture technology. It includes a bedside table body with several drawer boxes inside. Each drawer box has a sliding rail on both sides, and sliders fixed to the left and right sides of the drawer box, sliding within the sliding rails. A concealed compartment is located at the rear of the drawer box, containing several upper and lower storage compartments. This utility model's sliding pull-out mechanism and multi-compartment layout achieve secure storage of personal items and privacy protection. The concealed compartments fit perfectly with the bedside table, ensuring concealment and effectively utilizing cabinet space, increasing storage capacity without increasing size. The sliding rail and slider structure facilitates access to each storage compartment while enhancing the overall uniformity and aesthetics. It breaks through the traditional bedside table design, meeting daily storage needs while providing private storage space, balancing functionality and aesthetics.

This utility model provides an integrated device for lighting nodes on curtain walls, including a curtain wall keel and a glass curtain wall installed on the exterior of the curtain wall keel. It also includes lighting units installed at the cross-shaped connections between four adjacent glass units on the glass curtain wall. The inner end of each lighting unit is fixedly embedded in a square groove at the cross-shaped connection, and the power cord at the rear end of the lighting unit is pre-embedded in the supporting column of the curtain wall keel. This utility model integrates the lighting system with the curtain wall project, arraying lighting units at each cross-shaped connection on the glass curtain wall and pre-embedding power cords in the columns of the curtain wall keel. This allows the lighting units to be installed synchronously with the curtain wall keel and glass curtain wall, avoiding secondary construction damage and project delays. Furthermore, by concealing the power cords inside the curtain wall, it avoids exposed power cords that affect aesthetics, ensuring electrical safety and concealment.

The utility model discloses a folding pet resting nest, including front board, the back of front board both sides symmetry is provided with the side plate, front board both sides symmetry is provided with two rotatory seat, the inside fixed connection of rotatory seat has the pivot, the surface rotation of pivot is connected with the rotation block, the one end fixed connection of rotation block away from pivot has the oblique support board, the one end fixed connection of oblique support board away from rotation block has the clamping block, the inside of oblique support board is provided with the thread hole, the inside screw thread connection of thread hole has the connecting bolt, the one end fixed connection of connecting bolt away from side plate has the rotary disc. The utility model discloses through with front board, back plate, side plate and bottom plate and top plate fixed connection form resting nest whole, and through the folding of bottom plate and top plate realizes the folding and unfolding of resting nest, thereby convenient resting nest folding carries the stability of guaranteeing the connection between each board material, avoids producing separation.

This invention discloses a backdoor attack method for deep neural network models, comprising: constructing and pre-training a spatial adaptive feature selection network; processing images by dividing them into blocks and inputting them into the pre-trained spatial adaptive feature selection network, and introducing a weighted ranking mechanism to generate trigger materials; constructing a feature labeling network, inputting labels into the feature labeling network to generate a label mapping map; and generating poisoned samples using the trigger materials and the label mapping map. This invention's deep neural network model backdoor attack method solves the problem of low attack success rate caused by the simple trigger structure and weak spatial adaptability in existing technologies.
