Abstract: Techniques are described to address issues for repairing and/or servicing electronic components through the use of retaining assemblies that use bimetal retaining mechanisms. The bimetal retaining mechanisms may comprise various shapes such as hooks, snap-hooks, clips, etc., and facilitate a temperature-selective removal of various electronic components such as displays, EMI shields, etc. without damaging these components and without compromising the thickness and weight of the electronic device. External heating systems may be used to trigger actuation of the bimetal retaining mechanisms, resulting in their release. Alternatively, internal electronic device heating systems may be used.

The baffles suppress noise from a fan by slowing air flow and creating internal reflections within the heat exchanger that reflect noise away from the air flow path, absorbing sound energy and potentially setting up standing waves which dissipate noise via destructive interference. Other embodiments may be described and/or claimed.

Abstract: A variable pitch clamshell hinge for use with clamshell housings includes a first shaft coupled to a first variable diameter device and a second shaft coupled to a second variable diameter device. The first variable diameter device and the second variable diameter device are coupled together using an inelastic linking element. As the shafts are rotated in a first direction the variable diameter devices increase in diameter. As the shafts are rotated in a second direction that is opposite the first direction, the variable diameter devices decrease in diameter. As the variable diameter devices increase in diameter, the inelastic linking element exerts a compressive force on the variable diameter devices, decreasing the distance (i.e., the pitch) between the shafts. As the variable diameter devices decrease in diameter, the inelastic linking element relaxes the compressive force on the variable diameter devices, increasing the distance between the shafts.

A manufacturer may manufacture a chassis of an electronic device by machining a recess into a chassis preform and perform an anodization of the chassis. The manufacturer may machine the side of the chassis preform opposite the recess to a predefined thickness, and then perform a subsequent anodization. The predefined thickness is selected so that, after the subsequent anodization, there is a single anodized layer between the surface of the recess and the chassis surface on the opposite side. The single anodized layer is non-conductive, allowing electromagnetic signals of an antenna to pass through.

Abstract: Techniques for battery retention are disclosed. In the illustrative embodiment, a thin polyurethane strap is used to hold a battery in place. The strap only requires a small amount of volume, allowing for a higher volume (and higher capacity) for the battery. In order to accommodate swelling, a computing device that has a battery held in place with such a strap can have an open area above the battery. The strap may have ridges to contact the battery and the component above the battery beyond the open area. If the battery swells, the ridges may be pressed down, accommodating the swelling battery.
