    Abstract: This application relates to a low profile, small footprint cooling stack that does not extend substantially beyond a footprint of an integrated circuit to which it is affixed. The cooling stack utilizes a number of beam springs that supply a seating force to the integrated circuit by way of a metal slug. In some embodiments, a bottom surface of the metal slug can be contoured in accordance with a top surface of the integrated circuit and/or socket. In other embodiments a gap between peripheral portion of a bottom surface of the metal slug and an associated printed circuit board can be filled by a layer of foam to reduce auditory signals generated by the integrated circuit.

    Abstract: Variable friction clutch structures are described. In particular embodiments, the variable friction clutch structures are used to provide smooth and consistent movement of hinge assemblies of portable computers. The variable friction clutch can be configured to transition between a high frictional resistance mode and a low frictional resistance mode. In some embodiments, the variable friction clutches include cam systems. In some embodiments, the variable friction clutches include threaded shaft systems. In some embodiments, the variable friction clutches include mechanical linkage systems. In some embodiments, two or more variable friction clutches are included within a single hinge assembly for a portable computer. A space-saving wire clutch that can be used alone or in combination with the variable friction clutches is disclosed.
