    Abstract: A linear resonant actuator includes a ferritic tube, a movable mass, first and second flexures, and a set of one or more flexures. The ferritic tube has an axis extending from a first end of the ferritic tube to a second end of the ferritic tube. The movable mass has a set of magnet sections disposed along the axis. First and second flexures mechanically couple first and second ends of the movable mass to the ferritic tube. The flexures suspend the movable mass within the ferritic tube and allow movement of the movable mass along the axis. The electric coil(s) are attached to the ferritic tube and extend around the movable mass, between the ferritic tube and the movable mass. Each magnet section has magnetic poles disposed at different positions along the axis, and like magnetic poles of adjacent magnetic sections face each other.

    Abstract: The described embodiments relate generally to computing devices including liquid crystal displays (LCDs) and more particularly to methods for attaching a cover glass layer to a structural housing while minimizing an amount of stress transferred through the cover glass layer to the LCD module. A continuous and compliant foam adhesive can be used to bond the cover glass layer to a structural. The compliant bond can absorb and distribute local stress concentrations caused by structural loads, mismatched surfaces and differing thermal expansion rates between various structures and cover glass layer. This can reduce stress concentrations in the cover glass layer that can lead to stress induced birefringence in the LCD cell. In other embodiments, the cover glass layer can be attached using magnets or a tongue and groove design.

    Abstract: An electronic device can include a housing that defines an internal volume. The electronic device can also include a component within the internal volume that divides the internal volume into a first volume and a second volume. The first volume and second volume can be fluidically isolated except at an aperture defined by the component. An air-moving system can produce a positive air pressure in the first volume and a negative air pressure in the second volume.
