Abstract: An electronic device may have image transport layer material such as coherent fiber bundle material or Anderson localization material. The image transport layer material may overlap optical components. Optical sensor components can emit and/or detect light passing through the image transport layer material. Optical components such as light-emitting diodes may emit light through image transport layers. An image from a display may pass through an image transport layer. Infrared light-emitting diodes, infrared photodetectors, and/or other optical sensor components may be used to form a two-dimensional optical touch sensor that is configured to gather touch input from an external object such as a finger of a user. The optical touch sensor may operate through an image transport layer.

Abstract: An electronic device, such as a watch, has an input mechanism, such as a crown, that may receive translational inputs, rotational inputs, and/or touch inputs. Inputs received at the crown may result in changes in operation of the electronic device and/or outputs, such as graphical outputs, provided by the electronic device. In various embodiments, the crown includes a retainer that couples an outer crown body to an inner crown body and secures an isolator between the outer crown body and the inner crown body. The embodiments of the crown described herein provide a simple and robust input mechanism for receiving rotational, translational, and touch inputs as described above, while simplifying part alignment, ensuring consistent rotation, and allowing for efficient manufacturing.

Abstract: A wearable electronic device includes a body, a housing component, a band operable to attach the body to a body part of a user, and a force sensor coupled to the housing component. The force sensor is operable to produce a force signal based on a force exerted between the body part of the user and the housing component. A processing unit of the wearable electronic device receives the force signal from the force sensor and determines the force exerted on the housing component based thereon. The processing unit may use that force to determine a tightness of the band, determine health information for the user, adjust determined force exerted on a cover glass, and/or to perform various other actions.

Abstract: An apparatus is designed to secure a component (e.g., battery) to a housing of an electronic device and to remove the power supply from the electronic device with minimal or no breaking. The apparatus may include an adhesive layer and a reinforcement layer (e.g., wire) that extends throughout the adhesive layer. When a force is applied to the adhesive layer, the reinforcement layer allows the adhesive layer to stretch and lengthen without breaking. The apparatus may further include an extension where the applied force can be initiated, and the reinforcement layer may extend into the extension. The reinforcement layer may also be used to sever the adhesive layer. For example, an applied force to the reinforcement layer can cut the adhesive layer. Alternatively, thermal energy may be applied to the reinforcement layer, causing the reinforcement layer to change shape and separate the adhesive layer.

The translucency enhancement features may be formed in a reflector layer or an electrode layer for the display. The translucency enhancement features may include microperforations in a reflector layer of the display, a light-filtering reflector layer of the display, or a reflector layer of the display that passes a portion of the light and reflects an additional portion of the light.

In some embodiments, damping analyses are used to determine the body composition of a user who is holding or wearing the device. In some embodiments, damping analyses are used to determine how much force a user is applying to a device via a touch input. In some embodiments, damping analyses are used to determine whether and to what extent a sensor is in contact with a body of a user.
