  • Patent number: 10847071
    Abstract: An electronic device may be provided with a display mounted in a housing. The display may have an array of pixels configured to display images. A display cover layer may overlap the array of pixels. A light sensor such as a color ambient light sensor may be mounted in the electronic device and may receive ambient light through an ambient light sensor window region in the display cover layer or other portion of the electronic device. A diffuser may be located between the display cover layer and the ambient light sensor. The diffuser may have a substrate such as a glass substrate. A lens layer may be supported by the substrate. The lens layer may be formed from a layer of ultraviolet-light-curable polymer in which an array of lenses has been formed. An infrared-light-blocking-and-visible-light-transmitting filter may be used to reduce infrared light reaching the ambient light sensor.

  • Patent number: 10785384
    Abstract: A submersible electronic device such as a waterproof cellular telephone may be provided with an image sensor. The image sensor may capture images of underwater objects. Control circuitry in the submersible electronic device may adjust image contrast and color balance based on information from sensors and other information. The electronic device may have an ambient light sensor. The ambient light sensor may be a color ambient light sensor and may be used in measuring ambient lighting conditions above water and underwater. A depth sensor may be used in measuring the depth of the image sensor and other components of the electronic device underwater.

  • Publication number: 20200294468
    Abstract: An electronic device may have a display with an array of pixels configured to display images for a user. The electronic device may have an ambient light sensor for gathering ambient light information. Control circuitry in the electronic device may control the array of pixels while gathering measurements with the ambient light sensor. This allows the control circuitry to determine which portion of each ambient light sensor measurement is due to ambient light exposure and which portion of each ambient light sensor measurement is due to stray light from the array of pixels. The control circuitry can then remove the stray light contribution to the ambient light sensor measurements to produce corrected readings of ambient light levels. Display adjustments such as display brightness changes and color changes can be made using ambient light readings.

  • Publication number: 20200250147
    Abstract: Replica unavailability in a distributed file system can be managed. For example, a processing device can detect that a replica of data in a volume of a distributed file system is unavailable. In response to detecting that the replica is unavailable, the processing device can create a copy of the data in a memory location that is within the distributed file system and external to the volume. The processing device can then execute a write request by modifying both the data in the volume and the copy in the memory location (e.g., to ensure consistency between the two).

  • Patent number: 10670786
    Abstract: An electronic device may be provided with a color ambient light sensor. The color ambient light sensor may be used to measure an ambient light spectrum over a wavelength range of interest. Control circuitry in the electronic device can take actions based on the measured ambient light spectrum such as adjusting the brightness and color cast of content on a display. A display may have a display cover layer. The color ambient light sensor can be mounted under the display cover layer and may receive ambient light through the display cover layer. The color ambient light sensor may have a tunable wavelength filter such as an electrically adjustable Fabry-Perot resonator. A light collimator may be interposed between the display cover layer and the Fabry-Perot resonator to collimate ambient light that is passed to the Fabry-Perot resonator. A light detector measures the light passing through the Fabry-Perot resonator.

  • Patent number: 10553179
    Abstract: An electronic device may be provided with a display mounted in a housing. The display may have an array of pixels that form an active area and may have an inactive area that runs along an edge of the active area. An opaque layer may be formed on an inner surface of a display cover layer in the inactive area of the display or may be formed on another transparent layer in the electronic device. An optical component window may be formed from the opening and may be aligned with an ambient light sensor such as a color ambient light sensor. The color ambient light sensor may have an infrared-blocking filter to block infrared light such as infrared light emitted by an infrared-light-emitting diode in the device. A light diffuser layer, light guide, and other structures may also be included in the ambient light sensor.

  • Publication number: 20190317454
    Abstract: An electronic watch includes a housing, a user-operable watch crown mounted to the housing, an electromagnetic radiation source emitting a beam of electromagnetic radiation toward a watch crown surface, and a sensor. The beam of electromagnetic radiation depends on a coherent mixing of electromagnetic radiation within a resonant cavity of the electromagnetic radiation source. The coherent mixing includes a mixing of a first amount of electromagnetic radiation generated by the electromagnetic radiation source and a second amount of electromagnetic radiation redirected into the resonant cavity by the watch crown surface. The sensor measures a first parameter of the beam of electromagnetic radiation and determines, using the measurement of the first parameter, a value of a second parameter characterizing movement of the watch crown. The second parameter may include a direction of rotation or speed of rotation of the watch crown, or other parameters.

  • Publication number: 20190317639
    Abstract: Disclosed herein are electronic devices having touch input surfaces. A user's touch input or press on the touch input surface is detected using a set of lasers, such as vertical-cavity surface-emitting lasers (VCSELs) that emit beams of light toward the touch input surface. The user's touch causes changes in the self-mixing interference within the VCSEL of the emitted light with reflected light, such as from the touch input surface. Deflection and movement (e.g., drag motion) of the user's touch is determined from detected changes in the VCSELs' operation due to the self-mixing interference.

    Abstract: Embodiments of the present disclosure provide an optical encoder for an electronic device. The optical encoder comprises an elongated shaft having an encoding pattern made up of axial markings and radial markings. The encoding pattern may be disposed around a circumference of the elongated shaft. The optical encoder also includes an optical sensor. In embodiments, the optical sensor includes an emitter and a photodiode array. The emitter causes light to shine on the encoding pattern. The encoding pattern reflects the light back to the photodiode array and the photodiode array determines movement of the shaft based on the reflected light.
