Abstract: An electronic device may be provided with optical markers. A marker may be formed from a coating. The coating may be patterned to form a two-dimensional optical code or may be patterned to form an outline or other recognizable marker structure that helps provide information about an electronic device. A device with a sensor such as a depth sensor or other sensor may gather information on the electronic device and its markers. This information may include information on images captured with an image sensor while the electronic device is illuminated by one or more light beams from the depth sensor or other light sources. Markers may be configured to serve as mixed reality optical markers in a mixed reality system. Analysis of the mixed reality marker images or other sensor data may reveal information on device type, device location, device size, device orientation, and other information on a marked device.

Abstract: An electronic device may have a housing surrounding an interior in which electrical components are mounted. A display may be mounted to housing structures in the device. The housing may have a rear wall. The display cover layer and rear wall of the housing may be formed from transparent glass layers. Coatings may be formed on inwardly facing surfaces of the transparent glass layers. A coating on a transparent glass layer may be formed from a thin-film interference filter having a stack of dielectric layers. The coating may include an ink layer on the thin-film interference filter.

Abstract: Asymmetrically strengthened glass articles, methods for producing the same, and use of the articles in portable electronic device is disclosed. The asymmetrically strengthened glass articles include glass articles having a deeper compressive stress layer in a thicker portion of the glass article. Using a budgeted amount of compressive stress and tensile stress, asymmetric chemical strengthening is optimized for the utility of a glass article. In some aspects, the strengthened glass article can be designed for reduced damage, or damage propagation, when dropped.

Abstract: The embodiments described herein relate to forming anodized films that have a white appearance. In some embodiments, an anodized film having pores with light diffusing pore walls created by varying the current density during an anodizing process is described. In some embodiments, an anodized film having light diffusing micro-cracks created by a laser cracking procedure is described. In some embodiments, a sputtered layer of light diffusing aluminum is provided below an anodized film. In some embodiments, light diffusing particles are infused within openings of an anodized layer.

Abstract: Oxide coatings that reduce or eliminate the appearance of thin film interference coloring are described. In some embodiments, the oxide coatings are configured to reduce the appearance of fingerprints. In some cases, the oxide coatings are sufficiently thick to increase the optical path difference of incident light, thereby reducing any inference coloring by the fingerprint to a non-visible level. In some embodiments, the oxide coatings have a non-uniform thickness that changes the way light reflects off of interfaces of the oxide coating, thereby reducing or eliminating any thin film interference coloring caused by the oxide coatings themselves or by a fingerprint.

Abstract: Head-mounted display systems and methods of operation that allow users to couple and decouple a portable electronic device such as a handheld portable electronic device with a separate head-mounted device (e.g., temporarily integrates the separate devices into a single unit) are disclosed. The portable electronic may be physically coupled to the head-mounted device such that the portable electronic device can be worn on the user's head. The portable electronic device may be operatively coupled to the head-mounted device such that the portable electronic device and head mounted device can communicate and operate with one another. Each device may be allowed to extend its features and/or services to the other device for the purpose of enhancing, increasing and/or eliminating redundant functions between the head-mounted device and the portable electronic device.
