    Abstract: A power converter circuit that includes two flying capacitors, is coupled to a regulated power supply node in a computer system. The power converter circuit magnetizes an inductor using the two flying capacitors during a first phase. During a second phase, the power converter circuit charges one of the flying capacitors, de-magnetizes the inductor, and transfers charge to the regulated power supply node. The power converter circuit magnetizes the inductor using the flying capacitors, and transfers charge to the regulated power supply node during a third phase. During a fourth phase, the power converter circuit again de-magnetizes the inductor, charges the one of the flying capacitors, and transfers charge to the regulated power supply node.

    Abstract: An electronic device may be provided with a conductive sidewall. An aperture may be formed in the sidewall. The sidewall may have a cavity that extends from the aperture towards the interior of the device. The cavity may be filled with an injection-molded plastic substrate. A dielectric block having a dielectric constant greater than that of the injection-molded plastic substrate and the antenna layers may be embedded in the injection-molded plastic substrate. The dielectric block may at least partially overlap an antenna. The antenna may convey radio-frequency signals at a frequency greater than 10 GHz through the cavity, the dielectric block, the injection-molded plastic substrate, and the aperture. The dielectric block may increase the effective dielectric constant of the cavity, allowing the antenna to cover relatively low frequencies without increasing the size of the aperture.

    Abstract: Various implementations disclosed herein include devices, systems, and methods for displaying a visual indication of audibility of an audible signal. In various implementations, a device includes a display, an audio sensor, a processor and a non-transitory memory. In various implementations, a method includes receiving, via the audio sensor, an audible signal and converting the audible signal to electronic signal data. In various implementations, the method includes obtaining environmental data that indicates audio response characteristics of a physical environment in which the device is located. In various implementations, the method includes displaying, on the display, an indicator that indicates a distance from a source of the audible signal at which the audible signal is audible. In some implementations, the distance is based on an amplitude associated with the electronic signal data and the audio response characteristics of the physical environment.

    Abstract: An electronic device may include a display and a lens module through which the display is viewable. The lens module may include a tunable lens with an adjustable spherical power, cylindrical axis, and/or cylindrical power. To tune the tunable lens to compensate for a viewer's eyesight, the display may present at least one target. The optical power of the tunable lens may be set based on the point of gaze relative to the at least one target. Multiple targets with associated optical powers may be presented and the optical power of the tunable lens may be set depending on which target is aligned with the point of gaze. The display may present an image through a masking layer with a ring of pinhole pairs. The electronic device may include an input device that receives user input regarding a perceived image associated with the display and the masking layer.

    Abstract: A display may include a waveguide. An input coupler may couple image light into the waveguide and an output coupler may couple the image light out of the waveguide. A surface relief grating on the waveguide may couple infrared light into the waveguide and may couple the infrared light out of the waveguide. The surface relief grating may additionally or alternatively couple reflected infrared light into the waveguide and out of the waveguide and towards an infrared sensor. The surface relief grating may also form a cross-coupler for the image light. The infrared sensor may gather infrared sensor data based on the reflected infrared light. Control circuitry may perform gaze tracking operations based on the infrared sensor data. The input and output couplers may also be formed from surface relief gratings or may include other optical components.

    Abstract: An electronic device is provided with a display and a light sensor that receives light that passes through the display. The display includes features that increase the amount of light that passes through the display. The features may be translucency enhancement features that allow light to pass directly through the display onto a light sensor mounted behind the display or may include a light-guiding layer that guides light through the display onto a light sensor mounted along an edge of the display. The translucency enhancement features may be formed in a reflector layer or an electrode layer for the display. The translucency enhancement features may include microperforations in a reflector layer of the display, a light-filtering reflector layer of the display, or a reflector layer of the display that passes a portion of the light and reflects an additional portion of the light.
