Abstract: A child safety seat includes a seat shell having a sidewall for restricting a sideways movement of a child sitting on the seat shell, the sidewall being provided with a locking slot, a buffering part movably connected with the seat shell, and a latching mechanism including a latch carried with the buffering part. The buffering part is movable between a stowed position where the buffering part is retracted toward the sidewall, and a deployed position where the buffering part protrudes sideways from the sidewall. The latch is movable relative to the buffering part between a locking state where the latch is engaged with the locking slot for locking the buffering part to the seat shell, and an unlocking state where the latch is disengaged from the locking slot for unlocking the buffering part so that the buffering part is movable relative to the seat shell.

Abstract: A filter medium contamination detection structure may comprise a filter element and a prompt assembly. The prompt assembly may comprise a first pressure sensor, which may comprise a signal output end, and a second pressure sensor, which may comprise a signal output end. The first pressure sensor may be connected to a water inlet of the filter element, and the second pressure sensor may be connected to a water outlet of the filter element or outside air. The signal output ends of the first pressure sensor and the second pressure sensor may be connected to a signal input end of a controller. When the filter element is dirty, a pressure at the water inlet end may increase or a pressure at the water outlet end may decrease, and the difference between the first sensor and the second pressure sensor may increase.

Abstract: A contamination prompt structure for a filter medium may comprise a filter element and a prompt assembly. The prompt assembly may have a movable part. One end of the movable part may be in communication with one of a water inlet of the filter element, or a water outlet of the filter element, and the other end of the movable part may be in communication with the other one of the water inlet of the filter element, the water outlet of the filter element, or outside air. When the filter element is in a contaminated state, a rise of pressure at the water inlet or a drop of pressure at the water outlet may drive the movable part to move to send a prompt for a user to replace the filter element.

The seat shell includes a backrest portion having a front surface and at least one sidewall arranged at a side of the front surface, and an opening is formed in the sidewall. The buffering part is arranged at the sidewall, the buffering part being rotatable relative to the sidewall between a first position and a second position, wherein the buffering part is positioned at the sidewall such that during a sideways collision the buffering part urges the sidewall to bend inwardly.

Abstract: Systems and techniques for multi-task equidistant embedding are described that process categorical feature data to explore feature interactions. A digital analytics system enforces an equidistant relationship among features within a category while extracting high-order feature interactions by punishing both positive correlations and negative correlations among low-dimensional representations of different features. By enforcing an equidistant embedding, information is retained and accuracy is increased while higher order feature interactions are determined. Further, the digital analytics system shares knowledge among different tasks by connecting a shared network representation common to multiple tasks with exclusive network representations specific to particular tasks.

Abstract: A buckle (100) includes a male buckle (110), a female buckle (120), and an actuating structure (130) disposed between the male buckle (110) and the female buckle (120). When the male buckle (110) and the female buckle (120) are engaged, the actuating structure (130) generates an actuating signal.
