    Abstract: A wearable device includes a housing; a wrist band attached to the housing; first and second emitters positioned within the housing and configured to respectively emit, through a back of the housing, a first beam of electromagnetic radiation having a first infrared (IR) wavelength and a second beam of electromagnetic radiation having a second IR wavelength. The second IR wavelength is different from the first IR wavelength. The wearable device also includes a photodetector positioned within the housing and filtered to detect a set of electromagnetic radiation wavelengths including the first IR wavelength and the second IR wavelength; and a matter differentiation circuit configured to indicate, at least partly in response to signals indicating amounts of the first IR wavelength and the second IR wavelength received by the photodetector, whether the back of the housing is likely proximate to human tissue.

    Abstract: An electronic device can include a housing that includes an optically transparent component. First and second light emitters can be positioned in the internal volume defined by the housing. A light detector can be positioned in the internal volume and can be optically isolated from the first and second light emitters within the internal volume. An opaque material can be disposed on the optically transparent component and can be positioned to inhibit light emitted from the second light emitter from reaching the light detector and to allow light emitted from the first light emitter to reach the light detector.

    Abstract: A watch having a cover is described. An optical sensor subsystem is attached adjacent to or directly on an interior surface of the cover. In some cases, the optical sensor subsystem includes a substrate to which a light emitter and a light receiver are attached. The light receiver is configured to receive light emitted by the light emitter and reflected from the skin of a person that wears the watch. In some cases, the light emitter and light receiver are separated by a light-blocking wall that abuts the interior surface of the cover. In some cases, a light filter is attached adjacent or directly on the interior surface of the cover, between the cover and the light receiver.

    Abstract: An electronic device can include a housing defining an aperture, and an electromagnetic radiation emitter and an electromagnetic radiation detector disposed in the housing. An optical component can be disposed in the aperture and can include a first region of a first material having a first index of refraction, the first region aligned with the electromagnetic radiation emitter, a second region of the first material, the second region aligned with the electromagnetic radiation detector, and a bulk region surrounding a periphery of the first region and a periphery of the second region, the bulk region including a second material having a second index of refraction that is lower than the first index of refraction.

    Abstract: This relates to an electronic device configured for optical sensing having shared windows and including light restriction designs. The light restriction designs can include one or more of optical layers, optical films, lenses, and window systems configured to reduce or eliminate crosstalk between optical components. A plurality of accepting sections and a plurality of blocking sections can be employed to selectively allow light having an angle of incidence within one or more acceptance viewing angles and block light with angles of incidence outside of the acceptance viewing angles. In some examples, the light restriction designs can include variations in optical and structural properties can allow the light restriction designs to have spatially varying acceptance angles. Variations in structural properties can include, but are not limited to, differences in widths, heights, and/or tilts of the accepting sections and/or blocking sections.
