Abstract: AC inlets that have a low profile, are able to withstand side-to-side and axial forces, and are readily manufactured. An example can provide an AC inlet having a low-profile by providing power and ground prongs where the power and ground prongs are attached to flanges that can extend laterally from a back end of each prong. This lateral distribution of power and ground can reduce a depth of the AC inlet and provide the AC inlet with a low profile.

Abstract: Disclosed is a drying-wetting separated filling method and a filling apparatus for an electrowetting display device. The filling method comprises filling a non-polar solution into pixel grids on a lower substrate of an electrowetting display device in air, and filling a polar solution to immediately cover the non-polar solution filled after filling the non-polar solution into the pixel grids.

With the method, the fillings of the polar solution and the non-polar solution are easy, having a higher filling efficiency, and no air bubble residue.

Abstract: The present invention provides a dual rail track system for independently moveable carts in an industrial control environment in which upper and lower rails of a track are substantially “L” shaped to allow upper and lower groups of rollers of a cart to orthogonally contact the upper and lower rails, respectively, to provide vertical and horizontal control of the cart while in motion along the track. The shape of the rails and arrangement of the rollers, orthogonal with respect to the rails in vertical and horizontal planes, provides an efficient support system allowing high speed movement of carts, including through turns, with only two rails and with symmetric weight distribution of the cart. Flexible members provided with respect to each roller also provide resiliency to allow the rollers to adapt to variations in the track.

Abstract: Connector receptacles having protective doors.

When the card is inserted properly, the cam can rotate about an axis and the door can open allowing the card to access to the contacts of the connector receptacle. A second door in front of the protective door can be included to provide enhanced functionality and to provide a more uniform appearance.
