Abstract: An electronic device configured to provide localized haptic feedback to a user on one or more regions or sections of a surface of the electronic device. A support structure is positioned below the surface, and one or more haptic actuators are coupled to the support structure. In some examples, the support structure is shaped or configured to amplify a response to a haptic actuator. When a haptic actuator is actuated, the support structure deflects, which causes the surface to bend or deflect at a location that substantially corresponds to the location of the activated haptic actuator. In some examples, prior to providing haptic feedback, at least one haptic actuator is electrically pre-stressed to place the haptic actuator(s) in a pre-stressed state. When haptic feedback is to be provided, at least one haptic actuator transitions from the pre-stressed state to a haptic output state to produce one or more deflections in the surface. In other examples, a haptic structure incorporates a piezoelectric element that is shaped to reduce the overall cost of the haptic structure while still providing high actuation performance.

Abstract: An electronic device may include a first bias lens that transmits world light to an output coupler on a waveguide. The output coupler may transmit the world light while coupling image light out of the waveguide. A second bias lens may transmit the world light and the image light to an eye box. A tint layer may transmit the world light towards the output coupler. The tint layer may be planar and layered onto a planar surface of the first bias lens or another lens, may be separated from the first bias lens by an air gap, may be non-parallel relative to the waveguide, and/or may be curved and separated from the first bias lens and the waveguide by air gaps. When planar, the tint layer may be provided with spacers between substrates or between the tint layer and the waveguide to maximize parallelism.

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: An electronic device includes an electrostatic conductive layer for providing haptic feedback at an input surface of the electronic device. The electrostatic conductive layer is included in a cover assembly positioned over a display. The cover assembly includes a cover sheet, a touch sensor, and the electrostatic conductive layer. The electrostatic conductive layer is driven by an electric field, which electric field is produced by the touch sensor. When the electrostatic conductive layer is activated, it may provide frictional or other tactile feedback at the input surface.

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.

Abstract: In some embodiments, a haptic actuator includes piezoelectric material and a pattern of voltage electrodes coupled to a surface of the piezoelectric material. The voltage electrodes are individually controllable to supply voltage to different portions of the piezoelectric material. Different sections of the piezoelectric material are operable to deflect, producing haptic output at those locations, in response to the application of the voltage. Differing voltages may be provided to one or more of the voltage electrodes to affect the location of the deflection, and thus the haptic output. In various embodiments, a haptic output system incorporates a sealed haptic element. The sealed haptic element includes a piezoelectric component that is coupled to one or more flexes and is sealed and/or enclosed by the flex(es) and an encapsulation or sealing material.

Abstract: An electronic device may have layers of glass for forming components such as a display. A display cover glass layer may overlap an array of pixels. A touch sensor may be formed under the display cover glass layer. Conductive structures such as transparent conductive electrodes or other conductive layers of material may be formed on the outer surface of the display cover glass layer. The electrodes on the outer surface of the display cover glass layer may be coupled to metal contacts and other circuitry on the inner surface of the display cover glass layer using conductive vias. Vias may be provided with barrier layers, opaque coatings, tapers, and other structures and may be formed using techniques that enhance compatibility with chemical strengthening processes.

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.
