Abstract: A head-mounted device may include optical assemblies for presenting images to a user. Optical assembly positioning systems may be used to adjust the spacing between the optical assemblies to accommodate different interpupillary distances. The optical assembly positioning systems may have motors. Nose pressure sensors may be provided to detect nose pressure as optical assemblies are moved towards each other and towards nose surfaces by the motors. Motion of the optical assemblies can be halted whenever the detected nose pressure rises. The nose pressure sensors may each include an air pressure sensor and a pressure-sensing compressible air-filled chamber coupled to the air pressure sensor.

Abstract: A head-mountable device including a frame, a display positioned in the frame, a processor, and a facial interface connected to the frame. The facial interface can include a sensor electrically coupled to the processor. The sensor can collect biometric information from a nasal region of a user and generate a signal based on the biometric information.

Abstract: Disclosed herein are electronic devices, including wearable electronic devices, and components and configurations thereof, having one or more temperature sensors separated from the point of contact of the electronic device and an object, such as a user, whose temperature is being measured. In some embodiments, the electronic device includes both a temperature sensor and a light (visible, UV, and/or IR) emitter and sensor. Various embodiments are disclosed by which a temperature sensor may be shielded or separated from a light emitter/detector. A spacer may be used to separate the temperature sensor from the device's housing that contacts the object. The spacer may include a thermal path from the housing to the temperature sensor, and may be opaque to the light detected by a light detector.

Abstract: One embodiment described herein takes the form of a wearable electronic device, such as a watch, including a housing, a memory and a processor located in the housing, and three or more sensors. Each sensor of the three or more sensors is configured to generate a measurement of a parameter. Each sensor of the three or more sensors is located in a different region in the housing. The processor is configured to execute instructions stored in the memory. In response to execution of the instructions by the processor, the processor is configured to generate an adjusted measurement of the biometric parameter using at least the measurements of the parameter generated by the three or more sensors. The parameter is a temperature, and the biometric parameter is a body temperature of a user.

Abstract: An electronic device includes display layers such as liquid crystal display layers and a backlight unit that provides illumination for the display layers. The backlight unit includes light-emitting diodes that emit light into the edge of a light guide film. To minimize the inactive area of the display, the light-emitting diodes are tightly spaced to approximate a line light source instead of point light sources. Color and/or luminance compensation layers are incorporated at various locations within the backlight structures to ensure that the backlight provided to the display layers is homogenous. A thin-film transistor layer of the display is coupled to a printed circuit board by a flexible printed circuit. The flexible printed circuit has additional solder mask layers to improve robustness, encapsulation, and traces with a varying pitch.
