Abstract: A display device including a display unit having a display panel and a camera; a posture adjustment driving unit configured to adjust a posture of the display unit; and a controller configured to control the posture adjustment unit to adjust the posture of the display unit to be raised to a top end of a vertical movement range of the display unit and to tilt downwards or to be lowered to a bottom end of the vertical movement range of the display unit and to tilt upwards, control the camera to detect if a viewer is viewing the display unit when the display unit is raised to the top end or bottom end of the vertical movement range, determine a current posture of the viewer when the viewer is detected, and control the posture adjustment unit to adjust the posture of the display unit so the current posture of the viewer is changed into an upright posture with eyes of the viewer being centrally located within an area of the display unit.

Abstract: A display device including a display unit having a display panel and a camera; a posture adjustment driving unit configured to adjust a posture of the display unit; and a controller configured to control the camera to capture a first image of a viewer viewing the display unit when the display unit is positioned at a first height, control the posture adjustment driving unit to move the display unit to a second height different than the first height, control the camera to capture a second image of the viewer viewing the display unit when the display unit is positioned at the second height, correct at least one of the first image and the second image based on orientation information of the display unit on capturing the first image and the second image, generate a 3D body mesh of the viewer using the first image and the second image, calculate a viewer-optimized display unit posture setting based on the 3D body mesh, and control the posture adjustment driving unit to move the display unit to a height correspondin

Abstract: A display device including a display unit having a display panel and a camera; a posture adjustment driving unit configured to adjust a posture of the display unit; and a controller configured to control the camera to capture a first image of a viewer viewing the display unit, calculate a first viewer posture inferred by an artificial intelligence model from the first image captured by the camera, control the posture adjustment driving unit to adjust the posture of the display unit to correspond to a feature point of the viewer based on the calculated first viewer posture, and control the posture adjustment driving unit to adjust the posture of the display unit to have a height fluctuation of a sinusoidal curve trajectory continuous within a vertical top-bottom movement range of the display unit based on the calculated first viewer posture.

Abstract: A vehicle seat including a spiral-shaped air-tube seat ventilation system having a seat pad module. The seat pad module includes a foam cushion member, with the cushion member defining a spiral groove. An elongated tube defining a plurality of orifices in fluid communication with the tube interior is disposed in the spiral groove, with a spacer fabric pad and a heating pad coupled to the foam cushion member. One or more of the seat pad modules is then coupled to one or more of the vehicle seat back and the vehicle seat base.

Abstract: An exhaust gas heat recuperation system for use with a boiler is disclosed. The heat recuperation system includes a plate-type heat exchanger for exhaust gas heat recovery for exchanging heat between an exhaust gas and a charge gas. The heat exchanger preferably includes a series of exhaust gas plates stacked alternately with, and parallel to, a series of charge gas plates. Each of the exhaust gas plates and charge gas plates have raised contained ridges to form a substantially sinusoidal path for directing the respective gas therealong. The shape of the path reduces exhaust gas particulate deposition. The charge gas flows in a countercurrent to the exhaust gas to facilitate maximum heat transfer. The heat exchange is particularly useful in laminar flow conditions.
