Abstract: A head-mounted device may include optical assemblies for presenting images to a user. Motors may be used to adjust the spacing between the optical assemblies to accommodate different interpupillary distances. Gaze trackers may be used to make interpupillary distance measurements and eye relief measurements. Adjustments to the positions of the optical assemblies may be made by the motors based on the interpupillary distance measurements and eye relief measurements.

Abstract: An electronic device may have a display cover layer provided with an infrared-transparent antireflection coating. A pixel array may emit visible light through the cover layer and the coating. An infrared emitter may emit infrared light and an infrared sensor may receive infrared light through the coating and the cover layer. The coating may include a stack of thin-film interference layers. The stack may include alternating lower and higher refractive index layers. The layers may have thicknesses and materials that configure the coating to exhibit an infrared transmittance of greater than 94% from 920 nm to 960 nm and a photopic reflectance of less than 1.5%. The coating may reflect visible light to prevent displayed images from being obscured by visible reflections. At the same time, some photopic reflectance of the coating may be sacrificed to maximize infrared transmittance and accommodate operation by the infrared emitter and sensor.

Abstract: An electronic device has a force sensor that determines a measure of applied force from a user contacting a cover glass of the device. In one embodiment, a frame at least partially encloses an interior of the electronic device and has an open end. A cover glass covers the open end of the frame and is movably connected to the frame to allow movement of the cover glass in response to one or more forces applied to an external surface of the cover glass. A plurality of strain probes is positioned under the cover glass, between the cover glass and the frame, and is arranged to output a plurality of strain signals response to the one or more forces applied to the cover glass. A force processing module is configured to at least calculate an amount of force applied to the cover glass based on the plurality of strain signals.

Abstract: A three-dimensional feature is formed in a surface of a component. Material is removed from the component by rotating an abrading tool about a first axis. While the abrading tool is rotated, the component (and/or a shaft coupled to the abrading tool) is rotated on a second axis. The second axis may be transverse to the first axis and may run through a center of the three-dimensional feature. The abrading tool may correspond to the three-dimensional feature. For example, the abrading tool may be configured to contact an entirety of an exterior of the three-dimensional feature during the removal operation, fill the three-dimensional feature during the removal operation, and/or have a shape that corresponds to the shape of the three-dimensional feature in two planes that are normal to each other.

Abstract: Transparent articles for use as outer surfaces of electronic devices and methods therefor are disclosed. A transparent cover can be provided over a display of portable electronic device to provide a protective outer cover over the display. The transparent cover can include material to mark, mask or color a portion of the transparent cover, such portion thereupon becoming opaque. The material can be provided in a recessed portion of an inner surface of the transparent cover, such portion being a portion of the transparent cover that is not over a usable portion of the display. The electronic device can, for example, be a portable electronic device.

Abstract: A method of forming an overmolded plastic structure on a metallic plate includes first bonding a component to the metallic plate. The component is bonded with an adhesive that adheres it to the metallic plate. A plastic structure is formed over at least a portion of the component and the metallic plate and the plastic structure primarily adheres to the component. The component can be a set of metallic signal conductors that are used to route electrical signals across the metallic plate and the adhesive can be used to electrically insulate the signal conductors from the metallic plate.
