Abstract: A head-mounted device may have a head-mounted frame. The head-mounted frame may have an internal frame member such as a metal frame member (metal frame structure). Frame structures such as polymer frame structures may be molded over the internal frame member and may be provided with lens openings. The head-mounted device may have lenses with waveguides that are mounted in the lens openings. The waveguides may be used in guiding images received from projectors to eye boxes for viewing by a user. Strain gauge circuitry may be attached to a central portion of the internal frame member. During operation of the head-mounted device, the strain gauge circuitry may measure for deformation of the internal frame member, so that image warping operations may be performed or so that other actions may be taken to correct for image distortion arising from the measured deformation.

Abstract: A head-mounted device may have projectors that provide images. Waveguides in lenses may be used in conveying the images to eye boxes. A head-mounted frame in the head-mounted device may have lens openings that receive the lenses. The frame may include a frame member such as an elongated metal member that extends across the frame above the left and right lenses. The frame may include frame structure such as polymer structures that cover the frame member and that are configured to form the lens openings. The frame member may have a cable channel. Cabling may be used to route signals between the projectors, strain gauge circuitry, control circuitry, and other circuits in the head-mounted device. The cabling may be received within the cable channel and encapsulated in a protective polymer. Additional polymer may be molded over the protective polymer to form the frame.

Abstract: The present disclosure is generally directed to the use of compositions that include antibodies, e.g., monoclonal, chimeric, affinity-matured or humanized antibodies, antibody fragments, etc., that specifically bind one or more epitopes within a Sortilin protein, e.g., human Sortilin or mammalian Sortilin, and have improved and/or enhanced functional characteristics, in treating and/or delaying progression of a disease or injury in an individual in need thereof.

Abstract: A light emitting device has a first mirror; and one or more active regions with a first active region adjacent to the first mirror. Each of active region includes quantum wells and barriers, and is surrounded by one or more p-n junctions. The active regions have a selected shape structure each with a tunnel junction (TJ). One or more apertures are provided with the selected shape structure; one or more buried tunnel junctions (BTJ), additional TJ's, planar structures and/or additional BTJ's, created during a regrowth process that is independent of a first growth process of the first mirror as well as the active region and the one or more TJs. One or more electrical confinement apertures are defined by the one or more BTJ's, additional TJ's, planar structures and/or additional BTJ's. A vertical resonator cavity is disposed over the electrical confinement aperture. A high contrast grating (HCG) operates as a second mirror positioned over the vertical resonator cavity.

Abstract: An exemplary extended reality presentation system determines that a depiction of an augmentable object within a field of view takes up a first portion of the field of view, and, in response to this determination, presents a first form of an overlay object within the field of view. The first form of the overlay object is graphically associated with the augmentable object. During the presenting of the first form of the overlay object within the field of view, the system determines that the depiction of the augmentable object has come to take up a second portion of the field of view, and, in response to this determination, replaces the first form of the overlay object with a second form of the overlay object within the field of view. The second form of the overlay object is distinct from the first form. Corresponding methods and systems are also disclosed.

Abstract: An exemplary extended reality presentation system presents, to a user, a field of view into an extended reality world, and identifies an augmentable object from a set of objects presented in the field of view. The system determines that the augmentable object is located at a first apparent proximity to the user, and presents, within the field of view, a first form of an overlay object graphically associated with the augmentable object. The first form is tailored to the first apparent proximity. Subsequent to determining that the augmentable object is located at the first apparent proximity, the system determines that the augmentable object has come to be located at a second apparent proximity to the user and replaces, within the field of view, the first form of the overlay object with a second form of the overlay object distinct from the first form and tailored to the second apparent proximity.
