An oral care implement having a multi-component handle. The oral care implement may include a head and a handle. The handle may have a front surface, a rear surface, and opposing first and second lateral surfaces. The handle may include an elongated handle body, a grip cover, and a transparent component. The elongated handle body and the grip cover may be opaque. The elongated handle body may form a portion of the front surface of the handle and the grip cover may form a portion of the rear surface of the handle. The transparent component may form a portion of each of the first and second lateral surfaces of the handle. Thus, the transparent component may form a window through the lateral surfaces of the handle.

A method and apparatus for distributing a number of utilities. The number of utilities may be coupled between a number of utility sources and a utility fixture. The number of utilities may be coupled between the utility fixture and a mobile system.

A process for forming a two layer plastic device with textures or drawings thereon and a structure formed by the structure are provided. An inner bottom layer has textures or drawings on the surface thereof which includes at least one enclosing space. A through hole is formed on the enclosing space so that the masking material can be filled into the space between the outer mold and the inner mold. Then the masking material enters into the enclosing space through the through hole. As a result, only one mold (the outer mold) is necessary for forming the masking layer, while in the prior art, two molds are needed. The whole process can be completed mechanically without any manual operation. A color of the masking layer may be different from that of the inner bottom layer so that the textures or drawings clearly exposes on the surface of the masking layer.

A method and apparatus for performing an assembly operation. A tool may be macro-positioned relative to an exterior of a fuselage assembly. The tool may be micro-positioned relative to a particular location on the exterior of the fuselage assembly. An end effector is removably associated with an external robotic device associated with an external mobile platform. The tool is removably associated with the end effector. An assembly operation may be performed at the particular location on the panel using the tool.

An apparatus is configured to be positioned between a boss and a shell of a pressure vessel. The boss includes a bore therethrough, and the bore has a longitudinal axis. The apparatus includes an annular body and a gas permeable feature. The annular body includes an inner surface configured to abut the boss and an outer surface configured to abut the shell. The annular body has opposite first and second ends relative to the longitudinal axis. The gas permeable feature is provided on the inner surface and extends at least from the first end to the second end. The disclosure also describes a pressure vessel including a shell, and boss, and an apparatus positioned between the boss and the shell. A method for forming a pressure vessel includes mounting a boss on a mandrel, positioning an annular fitting about a neck of the boss, forming a liner, and forming an outer shell.

A dual-interface coupler includes a utilities unit, a number of utility cables configured to provide a number of utilities to the utilities unit, a first coupling unit associated with the utilities unit, and a second coupling unit associated with the utilities unit. The first coupling unit is configured to mechanically couple the utilities unit to a first corresponding coupling unit and comprises a utility interface. The number of utilities are configured to flow from the utilities unit through the utilities interface. The second coupling unit is configured to mechanically couple the second coupling unit to a second corresponding coupling unit.

A method for coupling a number of utilities between a first system and a second system is provided. A first interface that couples the number of utilities between the first system and the second system is created between the first system and a utilities unit. The first interface is activated. A second interface between the second system and the utilities unit is deactivated, while the first interface remains activated.

An apparatus for accessing an interior of a fuselage assembly. A tower having a number of platform levels may be driven into a selected tower position within an assembly area. The interior of the fuselage assembly may be accessed using the number of platform levels.

A method for manufacturing a watertight zipper solves the problem of low watertight effect of the modern watertight zipper. The method includes producing a waterproof stringer tape and forming a waterproof layer by injection molding. The waterproof layer covers a lateral edge of the waterproof stringer tape and includes a plurality of recesses. The method for manufacturing the watertight zipper further includes forming an aperture in each of the plurality of recesses. The aperture extends through the waterproof layer and the waterproof stringer tape. The method for manufacturing the watertight zipper further includes forming a plurality of scoops in the plurality of recesses by injection molding.
