    Abstract: Embodiments are directed to an electronic device that includes a housing, a light emitter, a first detector positioned at a first separation distance from the light emitter, and a second detector positioned at a second separation distance from the light emitter. The electronic device can include a processor that is configured to cause the light emitter to emit light toward a user, receive a first measurement from the first detector based on a return of the emitted light from tissue of the user and receive a second measurement from the second detector based on a return of the emitted light from the tissue of the user. The processor can determine a decay constant of the emitted light using the first measurements and the second measurements, and determine a water content metric of the user using the determined decay constant.

    Abstract: An electronic device housing may include a display cover layer that overlaps an array of pixels. The cover layer or other portion of the housing may have an opening that forms an optical and audio port. Optical and audio components may be coupled to the port. A port cover may cover some or all of the port. The port cover may include one or more layers of mesh or other materials that allow light and sound to pass while blocking environmental contaminants. The optical components may include an ambient light sensor or other devices that receive light and/or may include devices that emit light. The audio components may include a microphone and/or a speaker. The optical component may emit or receive light that passes through the audio component. A structure in the interior of the housing may form a passageway coupled to the port through which sound and light passes.

    Abstract: An ambient light sensor system may be mounted in alignment with a window in a display cover layer associated with a display in an electronic device. The ambient light sensor system may have a light diffuser layer and an infrared-light-blocking filter. The light diffuser layer may have a polymer layer with embedded light-scattering desiccant particles. An ambient light sensor in the ambient light sensor system may receive ambient light through the light diffuser layer and the infrared-light-blocking filter. The infrared-light-blocking filter may have a polymer substrate and a thin-film interference filter formed from a stack of inorganic thin-film layers on the polymer substrate. Light-scattering desiccant particles may be incorporated into the polymer substrate of the infrared-light-blocking filter. Desiccant may also be incorporated into ambient light sensor support structures.
