Abstract: A display stand includes a frame, an actuated rotary mechanism coupled to the frame, a counterweight coupled to the actuated rotary mechanism and movable in a vertical direction during rotation of the display about the axis of rotation, and an elevation mechanism. The actuated rotary mechanism includes a display holder that is configured to mount a display to the frame and rotate the display about an axis of rotation. The counterweight and the display are located at opposite sides of a vertical plane that passes through the axis of rotation such that a combined center of mass of the display, the display holder, and the counterweight lies on the vertical plane. The frame is coupled to the elevation mechanism, and the elevation mechanism is configured to move the frame up and down.

Abstract: Human lying posture detections are disclosed. A human lying on a bed is detected by obtaining an image through a depth camera, detecting objects in the image and marking the objects in the image using 2D bounding boxes by deep learning, determining the human being in a lying posture in response to a width and a height of the 2D bounding box of the human meeting a predetermined condition, detecting one or more skin areas in the image and generating skin area 2D bounding boxes to mark each of the one or more skin areas using a skin detection algorithm, and determining the human being in the lying posture in response to the skin area 2D bounding boxes and the 2D bounding box of the bed meeting a predetermined positional relationship.

Abstract: A robotic assistant includes a wheeled base, a body positioned on the base, a foldable seat rotatably connected to the body, an actuator to rotate the foldable seat with respect to the body, and a control system that receives command instructions. The actuator is electrically coupled to the control system. In response to the command instructions, the control system is to control the actuator to rotate the foldable seat to a folded position or an unfolded position. The control system is further to detect whether an external force from a user has applied to the foldable seat, and release the actuator to allow the foldable seat to be manually rotated.
