A hinge area and processes of forming the hinge area are described. The hinge area is part of cover of a laptop computer. A material used for the cover is of a certain thickness. Stamping and forming a shape that defines the hinge area is performed on the material. The top of the shape is cut to provide for sides of the hinge area. Squeeze forging operations are performed to thicken the sides, and CNC machining is further performed on the sides.

Technologies are described for a hinge mechanism coupled to at least a dual-display device wherein the displays can rotate with respect to each other through 360 degrees. The hinge mechanism has at least one flexible connection member that follows a generally S-shaped path when the displays are in a tablet position. In some embodiments, a second flexible connection member can be added that follows a mirrored S-shaped path. The S-shaped path of the first flexible connection member and the mirrored S-shape path of the second flexible connection member together create a cross-configuration. In other embodiments, interconnected friction hinges can allow for a free-stop function at any point along the 360 degrees of rotation.

Embodiments described in this specification are generally directed to a bolted hinge assembly for a waterbox cover (a waterbox hinge assembly). The waterbox hinge assembly generally does not require welding on the waterbox cover or the heat exchanger in an HVAC system (HVAC unit hereinafter). Further, the waterbox hinge assembly may be installable to the HVAC unit without removing the heat exchange fluids (e.g., water, refrigerant, etc.) from the HVAC unit. In some embodiments, the waterbox hinge assembly can be installed on an HVAC unit without removing any bolts from the waterbox cover. Once installed, the waterbox hinge assembly can be left in place so that it can be reused anytime the HVAC unit is serviced.

In one general aspect, a computing device can include a lid, and a base coupled to the lid by a hinge. The hinge can include a first disc including a first pin coupled to the lid and an inner surface. The hinge can include a second disc including a second pin coupled to the base and an outer surface. The first disc can be concentric with and can partially surround the second disc. The hinge can further include a friction element disposed between the inner surface of the first disc and the outer surface of the second disc. The first disc can be configured to rotate about the second disc.
