Abstract: A glasses assembly can include a front cover, a suspension, and a waveguide held by the suspension. The front cover and the waveguide can define a gap. The glasses assembly can include a shroud at least partially disposed in the gap. The shroud can define a first end and a second end. The shroud can include an elastomer body and a core coupled with the front cover at the first end of the shroud.

Abstract: A head-mounted device may have display projectors that provide images. Waveguides may be used in conveying the images to eye boxes. Optical couplers such as prisms may be used to couple the images from the projectors into the waveguides. The waveguides may guide the images to output couplers that couple the images toward eye boxes for viewing by a user. During operation of the head-mounted device, sensor circuitry may be used to measure for potential misalignment between optical components such as projectors, couplers, and waveguides. Control circuitry may provide control commands to zero hold power piezoelectric actuators or other positioners based on the sensor measurements, thereby tilting and otherwise repositioning the optical components relative to each other to correct for optical component misalignment.

Abstract: A head-mounted device may include a housing having openings that receive lenses. Displays may output images. Waveguides that overlap the lenses may receive the images from the displays and may direct the images to eye boxes that are aligned with the lenses. Infrared light sources such as infrared light-emitting diodes or lasers may be used to supply infrared light to the waveguides. Each waveguide may have multiple localized output couplers that overlap the lenses. The localized output couplers of each lens each direct a beam of the infrared light out of the waveguide towards an eye surface in the eye box associated with that lens to produce an eye glint. A gaze tracker infrared camera may captured images of the eye glints to determine a user's point of gaze.

Abstract: Head-mountable devices can include adjustment mechanisms to achieve optimal alignment of optical components during and/or after assembly thereof within the head-mountable device. The alignment mechanisms can be integrated into the head-mountable device itself. A light projecting display element can be adjustable based on operation of one or more actuators within the head-mountable device (e.g., within an arm) to adjust a position and/or orientation of the light projecting display element relative to the waveguide onto which it projects light. The adjustment mechanisms can adjust the display element during initial assembly and/or be operated by actuators that actively adjust the alignment as needed over time.
