Abstract: A container opening support system, including an annular member and a securement assembly, positionable inside of an open end of a flexible membrane.

Abstract: A storage device tray has a form factor designed to support a larger storage device, and is configured to secure a small storage device, thereby acting as an adapter between storage device sizes. The storage device tray includes a sliding mechanism configured with pegs that may couple to screw holes in the storage device. The sliding mechanism also exerts a force against the storage device to secure that storage device, and may be locked to further secure that storage device. At least one advantage of this approach is that a storage device can be coupled to a storage device tray without using screws.

Abstract: A fixed rail comprises a first rail-surface facing upward and a second rail-surface facing downward. A movable rail is configured to be slidable relative to the fixed rail and to support a seat. At least one first roller is mounted on the movable rail. The at least one first roller is configured to receive a downward load imposed on the movable rail and to roll on the first rail-surface. At least one second roller is mounted on the movable rail and is configured to roll on the second rail-surface. At least one pressing member is configured to elastically deform and to upwardly press the at least one second roller upwardly against the second rail-surface.
