An oral care implement having a multi-component handle. The oral care implement may include a head and a handle. The handle may include a transparent component and an opaque component. The transparent component may have a front surface, a rear surface opposite the front surface, a first lateral surface, and a second lateral surface opposite the first lateral surface. The opaque component may at least partially cover the front and rear surfaces of the transparent component while leaving the first and second lateral surfaces of the transparent component exposed. Thus, the transparent component may form a window through the lateral surfaces of the handle.

An injection site for medical lines includes a tubular body made of molded plastic material within which an elastic element made of thermoplastic material is overmolded on an enlarged end of the tubular body. The enlarged end delimits an inner annular flange and is formed with at least one radial through-hole through which the elastic element is overmolded in order to rest axially against the inner annular flange and fill the radial through-hole with an appendage.

An electronic device having protruding features and a method for molding the protruding features to the electronic device are described. The protruding features may be formed by a molding tool that releases a material that flows through several apertures of a substrate. Also, the molding tool is positioned with respect to the substrate such that the material from the molding tool flows from an interior region of the substrate to an exterior region of the substrate via the several apertures. Accordingly, each aperture extends from an opening of the interior region and to an opening of the exterior region of the substrate. In some cases, the apertures may include a conical shape. For example, the opening in the interior region may include a diameter greater than a diameter of the opening in the exterior region. In this manner, the material, when cured, is mechanically secured to the substrate.

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 method for making an oscillating weight for an automatic winding mechanism of a self-winding watch including a central part made from a first composite material and a heavy sector made from a second composite material charged with heavy metal particles, the method including: forming the central part with a lateral rib and a rebate by injecting the first composite material into a mold; overmolding the heavy sector onto the central part by injecting the second composite material into a mold containing the central part, so that the second composite material fills the rebate and a gap underneath the lateral rib, so that the lateral rib is embedded in the second composite material and the central part and the heavy sector are interlocked.

An oral care implement having a multi-component handle, and method of manufacturing the same. The invention can be a method of forming a handle for an oral care implement comprising: a) forming a core structure of a first hard plastic; b) forming an elongated handle body of a second hard plastic that at least partially surrounds the core structure so that opposing lateral surfaces of the core structure remain exposed; and c) forming a grip cover of a resilient material over at least a portion of the elongated handle body.

A method and apparatus for installing a wheel arm assembly for an autonomous vehicle. The wheel arm assembly may be inserted into a base of the autonomous vehicle from the exterior of the base. A number of fasteners may be installed at the exterior of the base to attach the wheel arm assembly to the base of the autonomous vehicle.

A method for manufacturing a watertight zipper is provided to solve 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.

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.

The present invention relates to the display technology field, and provides a backplate, a plastic-iron integrated structure, a backlight unit, and a display device. The backplate is provided with a first through hole, and the first through hole has an inner wall and an outer wall which form a projection structure on the backplate. When the backplate is bonded with a plastic frame to form the plastic-iron integrated structure, the plastic frame not only contacts the inner wall of the first through hole, but also contacts the surface of the projection structure, thus increasing the contact area between the plastic frame and the backplate, and increasing the bonding force between the plastic frame and the backplate. Even when the plastic frame shrinks in case of fluctuations in temperature and/or humidity, the plastic frame is not easily separated from the backplate, and the stability of the formed plastic-iron integrated structure is improved.
