Abstract: Techniques of controlling heat from a heat source in an electronic device using a heat pipe, improved techniques include placing a thermal conductor such as graphite sheet in thermal contact with a heat pipe and an external surface such as a surface of a battery in an electronic device. In some implementations, the graphite sheet covers an area encompassing an end of the heat pipe. In some implementations, the graphite sheet is attached to the heat pipe using an adhesive.

Abstract: A computing device includes memory configured for storing executable instructions, a processor configured for executing the instructions, a foldable display layer configured for displaying information in response to the execution of the instructions, and a bend limit layer coupled to the foldable display layer and arranged substantially parallel to a display surface of the foldable display layer. The bend limit layer is configured to increase its stiffness non-linearly when a radius of a bend of the bend limit layer is less than a threshold radius of curvature of the foldable display layer, the threshold radius of curvature being greater than 1 mm and less than 20 mm.

Abstract: A head mounted display device may include a housing, including a user-facing cavity and an electronics compartment. At least one fan may be installed in the electronics compartment. A plurality of intake ports may be defined in a peripheral wall portion of the user-facing cavity, and at least one air discharge port may be defined in a wall portion of the electronics compartment. A plurality of air channels may extend between the user-facing cavity and the electronics compartment. Operation of the at least one fan may draw external air into the housing through the plurality of air intake ports into the user—facing cavity, and into the electronics compartment through the plurality of air channels, for discharge from the housing through the at least one discharge port, to provide cooling of the user-facing cavity and the electronics compartment.

Abstract: Techniques of managing heat within an electronic device include providing a vapor chamber as an external surface of an electronic device. For example, when the electronic device includes a thin notebook computer (e.g., an “ultrabook”), the vapor chamber may be, in its entirety or at least a part of, the d-case (i.e., the bottom cover or exterior surface of the laptop, opposite the keyboard and/or trackpad when the notebook computer is open). Such a vapor chamber may be very thin (as thin as 0.3 mm), while being about 50% more stiff and 50× more thermally conductive as aluminum, which may be used as the d-case in conventional notebook computers.
