Abstract: An electronic device includes an input device. The input device has an input/output module below or within a cover defining an input surface. The input/output module detects touch and/or force inputs on the input surface, and provides haptic feedback to the cover. In some instances, a haptic device is integrally formed with a wall or structural element of a housing or enclosure of the electronic device.

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 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: A display system may include a waveguide with an output coupler that couples image light out of the waveguide and towards an eye box. The output coupler may also transmit world light from real-world objects towards the eye box. A bias lens may pass the world light to the output coupler. An adjustable tint layer having multiple states that involve transmission of different amounts of the world light may be disposed between the bias lens and the output coupler. Different states may impart different colors and/or may impart a gradient transmission characteristic to the world light. The bias lens itself may form the adjustable tint layer. The adjustable tint layer may have a transparent electrode layer that is provided with one or more AC voltages that heat the adjustable tint layer. The adjustable tint layer may be a self-switching electrochromic device that includes a transparent solar cell.

Abstract: An electronic device is disclosed which includes a conductive layer for providing haptic feedback at an input surface of the electronic device. The conductive layer includes conductive particles within an organic compound, such as an epoxy. When the conductive layer is activated it may provide frictional or other tactile feedback at the input surface.

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: An electronic device is configured to provide localized haptic feedback to a user on one or more regions or sections of a surface of the electronic device. The localized haptic feedback is provided by an array of piezoelectric haptic actuators below the surface of the electronic device. Actuators within the array of piezoelectric haptic actuators are separately controllable by a control circuit layer. The control circuit layer includes control circuitry, a master flexible circuit which passes between rows of actuators, and an array of slave flexible circuits. Each slave flexible circuit is connected to the master flexible circuit and an actuator. In further examples, the array of piezoelectric haptic actuators provides a unified structure for detecting touch and force inputs.
