The screen comprises an upper part and a lower part below the upper part, the upper and lower parts of the screen being offset relative to each other, for example to create an overhang on the side of the screen facing the aft seat unit, such that, the upper part provides shoulder space for a passenger seated in the fore seat unit, and the lower part provides arm space, in which there is an arm rest, for a passenger seated in the aft seat unit.

Abstract: A detecting machine for a yield rate of bristles of a toothbrush and a detecting method for the bristles are provided. The detecting machine includes a power device and two rotating units, and the two rotating units are rotatably mounted on a side surface of the power unit. The two rotating units are disposed parallel to each other. When in a rotating condition, the two rotating units rotate in opposite rotating directions. When a manufacturer horizontally disposes a toothbrush between the two rotating units, the surfaces of the two rotating units may compress the bristles and pull the bristles toward a direction away from the toothbrush. Therefore the manufacturer can inspect whether the bristles are firmly mounted on the toothbrush.

Abstract: The inventive two-step process operates at low temperature, without any toxic heavy metals, to provide excellent sealing on anodized aluminum substrates, especially those aluminum substrates comprising silicon. The first step of the process seals the anodized surface and the second step passivates the anodized surface. The process allows for corrosion resistance in anodized aluminum and anodized aluminum alloys to be achieved that is comparable to traditional nickel based sealants, without the toxicity of nickel. The process additionally does not require any excessive temperatures, as required by hot water sealing processes. The composition used for the sealing step comprises soluble lithium ions, fluoride ions, and preferably, a complexing agent comprising phosphines, phosphonates and/or polymers of acrylic acid. The composition used for the passivation step comprises metal ions and preferably a complexing agent comprising phosphines, phosphonates and/or polymers of acrylic acid.

Abstract: A toothbrush head comprises a head base and a head frame framing the head base. The head base comprises a substrate with multiple sockets for inserting bristles. The substrate has an outer frame, a central component, and two lateral components. The outer frame comprises a space, a front inner wall, a back inner wall, and two lateral inner walls. The central component is positioned in the space of the outer frame and links to the front inner wall and the back inner wall thereof. Each of the two lateral components is positioned between the central component and each of the two lateral inner walls and links to each of the two lateral inner walls with junctions, respectively, allowing the two lateral components to be rotatable. The toothbrush head helps users to brush the teeth with Bass method without injuring the gingiva, and keeps the toothbrush clean after brushing the teeth.

Abstract: A toothbrush head includes a main body composed of multiple cylinder bodies, made of rigid material, and mounted by multiple bristles on the surface of each of the multiple cylinder bodies. The multiple cylinder bodies are separate or are connected to each other by connecting strips. A soft cladding layer is formed on an exterior of each of the multiple cylinder bodies. The toothbrush head can be connected to a brush holder to form a toothbrush. As each of the multiple cylinder bodies having multiple bristles can oscillate in different directions, the toothbrush can efficiently clean the teeth surface and crevices in different directions and facilitate convenience of cleaning.
