  • Publication number: 20200331364
    Abstract: An automotive seat rail includes a rail and an engaging structure. The engaging structure includes a fixing frame, an engaging member and an elastic member. The fixing frame includes a fixing portion and an abutting portion fixed to and abutting an inner rail respectively. The engaging member includes an engaging section, a base section, and a stress section sequentially coupled to each other and bent with respect to each other. The base section is pivotally coupled to the fixing frame, and the engaging section is engaged between the inner and outer rails. When the stress section is controlled by an external force, the engaging section is driven to release the engagement between the inner rail and the outer rail, so as to ensure the accurate action of the engaging structure and allow the engaging member to have better structural strength, smoother control, and more accurate engagement and disengagement effects.

  • Publication number: 20200135236
    Abstract: A mobile device enables a user to edit a video containing a human figure, such that an original human pose is modified into a target human pose in the video. In response to a user command, the mobile device first identifies key points of the human figure from a frame of the video. The user command indicates a target position of a given key point of the key points. The mobile device generates a target frame including the target human pose, with the given key point of the target human pose at the target position. An edited frame sequence is generated on the display including the target frame. The edited frame sequence shows the movement of the human pose transitioning into the target human pose.
