    Abstract: In some embodiments, a display stack includes a set of light-emitting elements, and a display backplane that includes a set of conductors and is electrically coupled to the set of light-emitting elements. A conductor in the set of conductors has a length, and a curved edge extending along at least a portion of the length. In some embodiments, a display stack includes a set of light-emitting elements; a set of transistors, electrically coupled to the set of light-emitting elements; and a set of conductors, electrically coupled to the set of transistors. The set of transistors may be electrically coupled to the set of conductors at a set of conductive pads. A plurality of conductive pads in the set of conductive pads is coupled to a single conductor in the set of conductors. The single conductor approaches different conductive pads in the plurality of conductive pads at different angles.

    Abstract: An electronic device includes a housing and a display. The housing defines an interior cavity and includes an optically-transmissive housing component. The display is disposed in the interior cavity and is viewable through the optically-transmissive housing component. An optoelectronic component is disposed in the interior cavity. An optical fiber extends between a first end positioned adjacent the optoelectronic component and a second end positioned adjacent the optically-transmissive housing component. The optical fiber defines a non-linear optical path between the first end and the second end. At least a portion of the optical fiber is laterally offset from a lateral edge of the display.

    Abstract: Aspects of the subject technology relate to particulate matter sensors for electronic devices. A particulate matter sensor may include three lasers, three total-internal-reflection lenses, and three detectors for detecting changes in the operation of the three lasers due to the principles of self-mixing interferometry. The three total-internal-reflection lenses may use internally reflective surfaces to tilt the three beams into three corresponding directions that form an orthogonal basis in the three dimensional space, so that a gas flow speed can be determined while maintaining a small, modular form factor for implementation of the sensor in portable electronic devices.

    Abstract: An electronic device such as an earbud may have control circuitry mounted in a housing. The housing may have portions such as an ear portion with a speaker port through which a speaker plays audio and a stalk portion that extends from the ear portion. Proximity sensors may be formed in the electronic device. For example, one or more proximity sensors may be formed on the ear portion to detect when a user has inserted an earbud into the ear of the user and/or one or more proximity sensors may be formed on a stalk portion to detect when a user is holding an earbud by the stalk or when a user is providing finger touch input such as taps, swipes, and/or other gestures on the stalk portion. The proximity sensors may be optical proximity sensors such as coherent self-mixing proximity sensors.

    Abstract: An electronic device may include a housing and relative humidity sensor in the housing. The relative humidity sensor may include a relative humidity-sensitive layer, a light emitter that emits light into the relative humidity-sensitive layer, and a light detector that detects light that has passed through the relative humidity-sensitive layer. The relative humidity may be determined based on the detected light. For example, the light may be measured interferometrically to determine a path length of the light to determine the relative humidity. Alternatively, the light may be scattered by plasmonic nanoparticles in a relative humidity-sensitive material to determine the relative humidity. As other examples, polarized light may pass through the relative humidity-sensitive layer and measured to determine the relative humidity, or light may be used to form sound waves that may be measured to determine the relative humidity. In this way, a light-based relative humidity-sensor may make relative humidity measurements.

    Abstract: A wearable device includes a device housing configured to be worn on a first surface of a user, a set of one or more SMI sensors, and a processor. The set of one or more SMI sensors is mounted within the device housing and configured to emit a set of one or more beams of electromagnetic radiation, with each beam emitted in a different direction extending away from the first surface. The set of one or more SMI sensors is also configured to generate a set of one or more SMI signals containing information about a relationship between the device housing and a second surface. The processor is configured to extract the relationship between the device housing and the second surface from digitized samples of the set of one or more SMI signals.
