Abstract: A pass-through camera in a head-mounted device may capture image data for displaying on a display in the head-mounted device. However, only low-resolution image data may be needed to display low-resolution images in the periphery of the user's field of view on the display. Therefore, the pass-through camera may only capture high-resolution images that correspond to the portion of the user's field-of-view that is being directly viewed and may capture lower resolution image data that corresponds to the real-world objects in the user's peripheral vision. To enable the camera module to selectively capture high-resolution images, the pass-through camera may include an image sensor with two or more pixel densities, a distortion lens, and/or one or more planar or curved mirrors. Any of the components in the camera module may be adjusted to change which portion of a scene is captured with high-resolution image data.

Abstract: A scene camera system that includes two or more mirrors that reflect light from a respective portion of a field of view (FOV) in front of the system and two or more cameras that each capture the light reflected by a respective one of the two or more mirrors. By using the mirrors to reflect the light, the cameras' entrance pupils are imaged to a location closer to a user's eyes to thus achieve a more accurate representation of the perspective of the user.

Abstract: A head-mounted device may have a display that displays content for a user. Head-mounted support structures in the device support the device on the head of the user. A non-removable lens system may be supported by the head-mounted support structures. The head-mounted support structures may be configured to receive a removable supplemental lens system. The removable supplemental lens system may be used to customize the head-mounted display to accommodate the user's vision. Information such as information on the optical characteristics of the removable supplemental lens system and the user's eyeglass prescription may be stored in the removable supplemental lens system using bar codes, text, programmable memory, or other data storage. When the removable supplemental lens system is installed in the head-mounted device, control circuitry in the head-mounted device may retrieve the stored information. A gaze tracker system or other sensors may be used in retrieving the stored information.

One or more contacts formed on a flexible circuit board may be aligned with the one or more openings in the bottom surface portion. In this way, the receptacle may be space efficient and provide a direct connection to a flexible circuit board inside an electronic device. A cosmetic cap may be placed in the recess to obscure the existence of the connector receptacle.

Abstract: An electronic device such as a wristwatch may have a housing with metal portions such as metal sidewalls. The housing may form an antenna ground for an antenna. An antenna resonating element for the antenna may be formed from a stack of capacitively coupled component layers such as a display layer, touch sensor layer, and near-field communications antenna layer at a front face of the device. An additional antenna may be formed from a peripheral resonating element that runs along a peripheral edge of the device and the antenna ground. A rear face antenna may be formed using a wireless power receiving coil as a radio-frequency antenna resonating element or may be formed from metal antenna traces on a plastic support for light-based components.

Abstract: An electronic device such as a head-mounted device may have displays. The display may have regions of lower (L) and higher (M, H) resolution to reduce data bandwidth and power consumption for the display while preserving satisfactory image quality. Data lines may be shared by lower and higher resolution portions of a display or different portions of a display with different resolutions may be supplied with different numbers of data lines. Data line length may be varied in transition regions between lower resolution and higher resolution portions of a display to reduce visible discontinuities between the lower and higher resolution portions. The lower and higher resolution portions of the display may be dynamically adjusted using dynamically adjustable gate driver circuitry and dynamically adjustable data line driver circuitry.

Abstract: Methods and devices related to fabrication and utilization of multilayer capacitors presenting coaxially arranged electrode layers. The capacitors may be self-shielded against electromagnetic interference with neighboring components. The capacitors may have reduced losses from fringing effects when compared to conventional capacitors. The coaxial capacitors may be two-terminal multilayer ceramic capacitors (MLCC). The design of the capacitors may facilitate an improved relationship between the electric and magnetic fields generated by the capacitor within the dielectric in some embodiments. In some embodiments, the placement of the terminals may lead to a cancelation of mutual inductances between the electrodes. Terminations that facilitate the coupling of the capacitor to a circuit board, as well as methods for fabrication of the capacitors are also discussed.

Abstract: This application relates to capacitors that resist deformation because of the configuration of their conductive and dielectric layers. The capacitors are multilayer capacitors that include multiple dielectric and conductive layers. The dielectric layers can be arranged in a way that creates a rigid barrier or dead zone, which can resist mechanical deformation when the multilayer capacitor is charged. In some embodiments, two or more multilayer capacitors are stacked together in an arrangement that causes each of the multilayer capacitors to cancel any deformations of the other when the multilayer capacitors are charged. In this way, noise exhibited by the multilayer capacitors can be reduced.

Abstract: A thin-film transistor layer, an organic light-emitting diode layer, and other layers may be used in forming an array of pixels on a substrate in a display. Vias may be formed through one or more layers of the display such as the substrate layer to form vertical signal paths. The vertical signal paths may convey signals between display driver circuitry underneath the display and the pixels. The vias may pass through a polymer layer and may contact pads formed within openings in the substrate. Vias may pass through a glass support layer. Metal traces may be formed in the thin-film transistor layer to create signal paths such as data lines and gate lines. Portions of the metal traces may form vias through a polymer layer such as a substrate layer or a polymer layer that has been formed on top of the substrate layer.
