Abstract: An electronic device may have light-emitting devices. A light-emitting device may include light-emitting diodes, a display, or other components that emit visual output. One or more image transport layers may be included in the electronic device. An image transport layer may have an input surface that receives an image and an output surface to which the image transport layer transports the image for viewing by a user. The image transport layers may have areas with compound curvature and other shapes. Deformed image transport layer structures such as deformed fibers in a coherent fiber bundle may be configured to hide gaps in displays and other structures. Displays may include light detectors that serve as a two-dimensional touch sensor. The touch sensor may detect touch input on an output surface of an image transport layer. Image transport layer material may be incorporated into buttons, elongated housings, wearable devices, and other equipment.

Abstract: A housing for an electronic device is disclosed. The housing comprises a first component and a second component separated from the first component by a gap. The housing also includes a first molded element disposed at least partially within the gap and defining at least a portion of an interlock feature, and a second molded element disposed at least partially within the gap and mechanically engaging the interlock feature. The first component, the second component, and the second molded element form a portion of an exterior surface of the housing. A method of forming the housing is also disclosed.

Abstract: A modular sensing assembly may be used to detect user inputs at an electronic device. Example user inputs include touch inputs, fingerprint inputs, translational inputs, audio inputs, biometric inputs, and the like. Inputs received using the modular sensing assembly may be used to control a graphical output of a display of the electronic device. A modular sensing assembly may be configured, for example, as a power button, a key of a keyboard, a control button (e.g., volume control), a home button, a watch crown, and so on.

Abstract: An electronic device may have a housing with portions that slide relative to each other. A display may be supported on a surface of the housing such as on a front face of the housing. The housing portions may slide between an unexpanded state in which the display has an unexpanded viewable area on the front face and an expanded state in which the display has an expanded viewable area on the front face that is greater than the unexpanded viewable area. The housing portions may have interior regions that contain electrical components. The display may be formed from a flexible display substrate. A portion of a flexible display may be stored in an interior region of the housing when the housing is in the unexpanded state. In the unexpanded state, the flexible display may have one or more bends and may double back on itself one or more times.

Abstract: An electronic device, such as a watch, has a housing to which a carrier is attached. The carrier has a first surface interior to the electronic device, and a second surface exterior to the electronic device. A set of electrodes is deposited on the exterior surface of the carrier. An additional electrode is operable to be contacted by a finger of a user of the electronic device while the first electrode is positioned against skin of the user. The additional electrode may be positioned on a user-rotatable crown of the electronic device, on a button of the electronic device, or on another surface of the housing of the electronic device. A processor of the electronic device is operable to determine a biological parameter of the user based on voltages at the electrodes. The biological parameter may be an electrocardiogram.

Abstract: An optical system may include a head-mounted support structure configured to receive a removable portable electronic device with a display to form a head-mounted device. A head-mounted device may also be formed by incorporating a non-removable display into a head-mounted support structure. An optical combiner may be coupled to the head-mounted support structure. During operation of the head-mounted device, real-world image light passes through the optical combiner to eye boxes in which the eyes of a user are located. Display image light from the display reflects from a curved partially reflective surface of the optical combiner towards the eye boxes. To make optical adjustments such as virtual image distance adjustments, one or more actuators may be used to mechanically adjust the optical combiner.
