Abstract: A method of operating a dynamic eyepiece in an augmented reality headset includes producing first virtual content associated with a first depth plane, coupling the first virtual content into the dynamic eyepiece, and projecting the first virtual content through one or more waveguide layers of the dynamic eyepiece to an eye of a viewer. The one or more waveguide layers are characterized by a first surface profile. The method also includes modifying the one or more waveguide layers to be characterized by a second surface profile different from the first surface profile, producing second virtual content associated with a second depth plane, coupling the second virtual content into the dynamic eyepiece, and projecting the second virtual content through the one or more waveguide layers of the dynamic eyepiece to the eye of the viewer.

Abstract: An annular axial flux motor includes a rotor mounted on an annular subsection of a rotatable cam ring and a stator mounted on an annular subsection of a carrier frame. The rotor includes two Halbach arrays of permanent magnets spaced from each other on the cam ring along an axial direction. The stator includes multiple phase electrical windings printed on multiple layers of a printed circuit board (PCB) that are stacked along the axial direction. The multiple layers are positioned between the Halbach arrays, with active side of the Halbach arrays facing to opposite sides of the multiple layers. The Halbach arrays are configured to generate a symmetrical magnetic field and the multiple phase electrical windings are configured to have a same rotor-dependent torque constant, such that the stator can generate a constant torque to rotate the rotor and the cam ring within a finite travel range.

Abstract: An example head-mounted display device includes a light projector, an optical assembly arranged to direct light from a light projector to a user, and an actuator module. The optical assembly includes a variable focus lens assembly including a rigid refractive component, a shaper ring defining an aperture, and a flexible lens membrane between the shaper ring and the rigid refractive component and covering the aperture. The refractive component, the shaper ring, and the lens membrane are arranged along an axis. The refractive component and the lens membrane define a chamber containing a volume of fluid. The actuator module is configured to adjust an optical power of the variable focus lens by moving the shaper ring relative to the refractive component along the axis, such that a curvature of the lens membrane in the aperture is modified.

Abstract: A dynamic eyepiece for projecting an image to an eye of a viewer includes a waveguide layer having an input surface, an output surface opposing the input surface, and a periphery. The waveguide layer is configured to propagate light therein. The dynamic eyepiece also includes a mechanical structure coupled to at least a portion of the periphery of the waveguide layer. The mechanical structure is operable to apply a first mechanical force to the at least a portion of the periphery of the waveguide layer to impose a first surface profile on the output surface of the waveguide layer and apply a second mechanical force to the at least a portion of the periphery of the waveguide layer to impose a second surface profile different from the first surface profile on the output surface of the waveguide layer.
