Abstract: Embodiments described include a system comprising a position sensing device (PSD) and a light source. The light source is configured to, by passing one or more light beams through the PSD, cause one or more electrical currents to flow through the PSD. The system further comprises a processor, configured to (i) in response to the electrical currents, ascertain an amount of power that is delivered by the light source, and (ii) in response to the amount of power exceeding a threshold amount of power, inhibit the light source from further operation. Other embodiments are also described.

Abstract: An electronic device may include a lens module with a tunable lens. The tunable lens may include multiple adjustable fluid-filled bladders distributed around the periphery of the tunable lens. Fluid may be selectively added to and removed from each adjustable fluid-filled bladder to control a displacement of a lens element at a given position along the periphery. The fluid may be added to and removed from the adjustable fluid-filled bladders by fluid-controlling components. The fluid-controlling components may be positioned locally within a ring-shaped chassis portion and adjacent to a respective bladder or may be consolidated in an additional chassis portion and connected to the bladders using fluid channels through the ring-shaped chassis portion. The fluid-controlling components may include stepper motors with two subassemblies that each have a ring-shaped magnet between two coils.

Abstract: A head-mounted device may have a display that displays content for a user. Head-mounted support structures in the device support the display on the head of the user. A lens module in the head-mounted device may include a transparent lens element, a positioner that extends around the periphery of the transparent lens element, and an actuator that selectively shifts the positioner in a first direction. Shifting the positioner in the first direction causes the transparent lens element to be biased in a second direction that is orthogonal to the first direction at multiple points around the periphery of the transparent lens elements. The positioner may be attached to guide structures that each have a respective angled slot. Each angled slot may receive a respective tab of the transparent lens element or a respective tab of a lens shaping element that is attached to the transparent lens element.

Abstract: A lens module may include a transparent lens element, a lens shaping structure that is coupled to the transparent lens element, and a plurality of actuators that are configured to adjust a position of the lens shaping structure to adjust the transparent lens element. The lens shaping structure may include a plurality of extensions that are each coupled to a respective actuator. To ensure the lens shaping structure has desired curvature between the extensions, the lens shaping structure may have a portion in one or more segments between adjacent extensions that has a property with a different magnitude than an additional portion of the lens shaping structure. The portion between the adjacent extensions may have an increased or decreased rigidity relative to the additional portions. The portion between the adjacent extensions may have a different width, thickness, or Young's modulus compared to the additional portions.

Abstract: An electronic device may include a display module that generates image light and an optical system that redirects the light towards an eye box. The optical system may have first hologram structures that replicate the light over multiple output angles onto second hologram structures. The second hologram structures may focus the replicated light onto the eye box. If desired, the device may include an image sensor. The first and second hologram structures may include transmission and/or reflection holograms. The optical system may redirect a first portion of the light to the eye box and a second portion of the light to the sensor. The sensor may generate image data based on the second portion of the light. Control circuitry may compensate for distortions in the first portion of the light by performing feedback adjustments to the display module based on distortions in the image data.

Abstract: In some embodiments, a plurality of expected values of a drive current corresponding to respective ones of a plurality of potential values of a Hall sensor output is determined. An actual value of the Hall sensor output is measured. An actual value of the drive current is measured. A potential value of the Hall sensor output corresponding to the actual value of the Hall sensor output is selected. The expected value of the drive current associated with the selected potential value of the Hall sensor output is compared to the actual value of the drive current. A value of the drive current is adjusted to reduce a difference between the expected value of the drive current associated with the selected potential value of the Hall sensor output to the actual value of the drive current.
