  • Patent number: 12124224
    Abstract: A watch body includes a housing at least partially defining an interior of the watch body. A retaining feature is formed in or extends from the housing. A watch crown is retained by the retaining feature and is operable to be rotated by a user. The watch crown has a surface facing the housing. The watch crown is entirely external to the interior of the watch body. An electromagnetic radiation source is disposed within the housing and is operable to emit a beam of electromagnetic radiation toward the surface. A sensor is disposed within the housing and is operable to characterize a movement of the watch crown based at least in part on a portion of the beam of electromagnetic radiation that impinges on the surface and is redirected by the surface.

  • Publication number: 20240094346
    Abstract: An optical system includes a housing defining a cylindrical lens array. A first light source is located in the housing and positioned to emit a first wavelength of light into a first field of illumination impinging on the cylindrical lens array. A second light source is located in the housing and positioned to emit a second wavelength of light into a second field of illumination impinging on the cylindrical lens array. The cylindrical lens array alters the first field of illumination and the second field of illumination and increases an overlap between the first field of illumination and the second field of illumination. A detector is located in the housing and positioned to receive a first redirected portion of the first wavelength of light and a second redirected portion of the second wavelength of light.

  • Patent number: 11860588
    Abstract: A watch can include a watch body and a band for securing the watch to the user. The watch body can detect an identification of the band or combination of band portions, which can serve as an input to initiate actions performed by the watch body. For example, a type, model, color, size, or other characteristic of a band can be determined and used to select a corresponding action performed by the watch body. Identification of the band can be performed by components of the watch body that also serve other purposes. The watch body can respond to the identification of a particular band by performing particular functions, such as changing an aspect of a user interface or altering settings of the watch body.

  • Publication number: 20230288186
    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.

  • Patent number: 11650961
    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: 11644800
    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.

  • Patent number: 11015960
    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.

  • 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.
