These optical devices have dynamic adjustable feature for the luminous radiation and the heat transfer that flows throuhg the window aperture.

It is found out that automobile seats with adjustable suspension spring stiffness and damping or one of these two all have good dynamical adjustability, and they can meet the requirement of dynamical adjustment, thereby the theoretical work has been done for improving ride comfort of automobile.
