    Abstract: An electronic device may include a display with a waveguide that directs image light to an eye box using an output coupler. The display may include an electrically adjustable tint layer overlapping the output coupler. The tint layer may serve to maximize contrast of images in the image light. The tint layer may include a peripheral edge seal between first and second substrates and laterally surrounding an electrochromic gel. The peripheral edge seal may protect the gel from water and oxygen. The peripheral edge seal may include one or more rings of material and/or a glass ring spacer, the substrates may include cavities, and/or the gel may include spacer beads to help minimize warpage upon curing and thus maximize flatness of the tint layer. The electrochromic gel may include first and second redox species and a third redox species configured to tune a color response of the tint layer.

    Abstract: One or more strain sensors can be included in an electronic device. Each strain sensor includes a strain sensitive element and one or more strain signal lines connected directly to the strain sensitive element. The strain sensor(s) are used to detect a force that is applied to the electronic device, to a component in the electronic device, and/or to an input region or surface of the electronic device. A strain sensitive element is formed or processed to have a first gauge factor and the strain signal line(s) is formed or processed to have a different second gauge factor. Additionally or alternatively, a strain sensitive element is formed or processed to have a first conductance and the strain signal line(s) is formed or processed to have a different second conductance.

    Abstract: A notebook computer may include a display portion, a base portion, a hinge mechanism movably coupling the display portion to the base portion, an optical sensing system configured to capture an image of an object, an actuation system comprising a shape-memory alloy member coupled to the base portion and the display portion and configured to move the display portion relative to the base portion, and a processing system. The processing system may be configured to determine a target position for the display portion based at least in part on a location of the object in the image and cause the actuation system to actuate the hinge mechanism to move the display portion, relative to the base portion, from an initial position to the target position.

    Abstract: A lens module in a head-mounted device may include a fluid-filled chamber, a semi-rigid lens element that at least partially defines the fluid-filled chamber, and at least one actuator configured to selectively bend the semi-rigid lens element. The semi-rigid lens element may become rigid along a first axis when the lens element is curved along a second axis perpendicular to the first axis. Six actuators that are evenly distributed around the periphery of the semi-rigid lens element may be used to control the curvature of the semi-rigid lens element. The semi-rigid lens element may initially be planar or non-planar. For example, the semi-rigid lens element may initially have a spherically convex surface and a spherically concave surface. A tunable spherical lens may be incorporated into the lens module to offset a parasitic spherical lens power from the semi-rigid lens element.
