Abstract: The present subject matter relates to techniques for selectively rendering content in 2D view and 3D view, for example, based on a choice of the user. In an example, a display may include a set of light sources and a 3D panel that may further include a 3D lens. In one example, the 3D lens may be selectively positionable in a first position where the 3D lens is positioned in a path of light emitted by the set of light sources.

Abstract: In one example, a hinge assembly is disclosed, which may include a band torque engine having at least one bearing portion and a vertical torque engine coupled to the band torque engine. The vertical torque engine may have an opening. The hinge assembly may include a first shaft received through the at least one bearing portion and the opening. The first shaft may be rotatable along an axis with respect to the band torque engine and the vertical torque engine. The hinge assembly may include a display bracket including an adaptor portion to hold the first shaft such that the first shaft rotates along with the display bracket. The band torque engine may provide a frictional torque and the vertical torque engine may compressively engage with the first shaft to provide a vertical frictional torque during rotation of the display bracket.

Abstract: A surface finishing method comprises applying coatings of a hydrophobic material and a water-borne material to a surface of a metal substrate. First, a patterned coating of a first one of the hydrophobic or water-borne materials is applied to a surface of the metal substrate to partially cover the surface. A second fill coating of the other of the hydrophobic or water borne materials is then applied after the first patterned coating whereby the water borne material and the hydrophobic material repel and the second fill coating coats the surface of the metal substrate in areas uncoated by the first coating.
