Abstract: The disclosed head-mounted display systems may include an optical element supported by a head-mounted display frame, a projector mounted to the head-mounted display frame, and at least one voice coil actuator mounted on the head-mounted display frame. The projector may be configured to project, via the optical element, an image toward an eye of a user of the head-mounted display system. The at least one voice coil actuator may be coupled to at least one of the projector or the optical element. When actuated, the at least one voice coil actuator may translate at least one of the projector or the optical element in at least one direction relative to the head-mounted display frame. Various other methods, systems, and methods of manufacture are also disclosed.

Abstract: In one example, an apparatus may include a frame that includes an optical component configured for use with a near-eye display that is part of a head-worn display system. The frame magnetically attaches to the head-worn display system, and when the frame is attached to the head-worn display system, the frame may align the optical component for use with the near-eye display. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A head-mounted display device includes a first set of one or more lenses and a first display configured to provide visual data through the first set of one or more lenses. The head-mounted display device further includes a first stepper motor mechanically coupled to the first display, and the first stepper motor is configured to move the first display along a first axis by rotating a rotatable component of the first stepper motor. The head-mounted display device further includes a first electronic controller configured to (i) determine a first position of the first display, (ii) receive information identifying a second position of the first display, and (iii) generate one or more electrical signals that cause the first stepper motor to move the first display from the first position to the second position along the first axis.

Abstract: A head-mounted display device includes one or more lenses and a display configured to provide visual data through the one or more lenses. The head-mounted display device also includes a direct-current (DC) motor mechanically coupled to the display, and the DC motor is configured to move the display along an axis by rotating a rotatable component of the DC motor. The head-mounted display device further includes: position sensor(s) configured to determine a position of the display, and electronic controller(s) in communication with the position sensor(s). The electronic controller(s) are configured to: (i) receive, from the position sensor(s), the determined position of the display as a first position of the display, (ii) receive information identifying a second position of the display, and (iii) generate electrical signal(s) that cause the DC motor to move the display from the first position to the second position along the axis.

Abstract: A flexure guidance system may be provided for controlling movement of an optical subassembly and/or a connected combiner lens. For instance, the flexure guidance system may include a distal end piece, a proximal end piece, and multiple wire flexures that link the distal end piece to the proximal end piece. The linking wire flexures may be spaced to form an interior cavity between the distal end piece and the proximal end piece. This interior cavity may house various electronic components. One or more actuators in the system may move the electronic components according to input signals along different axes of movement provided by the wire flexures. Various other methods, systems, and computer-readable media are also disclosed.

CPC classification number: G02B7/10
Abstract: The disclosed systems for varifocal adjustments may include a frame, an optical lens pair supported by the frame, and a flexure assembly. The optical lens pair may include a first lens that is movably coupled to the frame and a second lens that is fixedly coupled to the frame. The flexure assembly may be configured to constrain movement of the first lens to a substantially linear pathway. The flexure assembly may include at least one substantially planar flexure element having a first movable end portion coupled to the first lens and a second fixed end portion coupled to the frame. Various other devices, systems, and methods are also disclosed.
