Abstract: Multi-sectioned arms are used as a basic mechanism for coupling the display and the base of a portable computer. With this mechanism, one single computer can support all of the following capabilities. The display can move continuously, relative to the back edge of the base, along any combination of up and down, backward and forward, and left and right directions. The display can be tilted up and down as well as sideway for viewing angle adjustment, and also set to portrait and landscape orientations. When the display is in conventional open or close positions, each arm can be folded and parked alongside and parallel to as well as away from the edge of the base. The arms can be detached from the computer. The base and the display can overlay each other in four ways. Finally, mechanical mechanisms for implementations of the arms and connections to the computer including friction joint mechanisms and attachment mechanisms for connecting the arm to the display and the base, are presented.

Abstract: A connecting rod is composed of two or more assembled shells made of a composite, open over the entire length of the connecting rod. The shells incorporate clevis joints for introducing stress at each of their ends. The shells are produced separately then assembled together to form a sealed section. Each shell is made from a material preimpregnated with long fibres. The production of each shell is simplified due to the overall shape of the shell as a simple curve, thus a shell may be produced industrially, for example, by thermoforming a flat composite preform. The two shells are assembled by simultaneous polymerization of the shells, by bonding, by welding, by riveting or any other assembly process or combination of assembly processes that are compatible with one another. The structural composite connecting rod obtained has very good mechanical properties, especially in compression, with a simple and economic production process.
