Abstract: A facet fusion tube assembly includes an elongated tube that defines a working channel to accept tools, instruments or materials for conducting a facet fusion. The tube includes a clip on its outer circumference that is configured to engage the outer surface of an adjacent tool or instrument used to access and engage the pedicle. A centering cap can be mounted at the proximal end of the elongated tube to align and center a working tool, such as a burring tool. An inner removable rod can extend through the tube to prevent soft tissue migration into the tube during insertion, and can be used for bone graft packing once the facet joint or other area of the spine is prepared for fusion. In use, the tube is clipped onto an adjacent instrument or tool to anchor the facet fusion tube assembly in a proper orientation relative to the facet joint.

Abstract: Systems and methods dynamically control optical conditions presented to a user by an artificial reality system according to monitored visual experience parameters for the user. For example, the artificial reality presentation to the user can be tracked to monitor visual experience parameters, such as light characteristics (e.g., color), focal distances, virtual object characteristics (e.g., objects/text color, size, etc.), aggregated defocus distance of background, luminance, activity, eye movement, accommodation distances, and other suitable conditions. Implementations can vary optical conditions presented/displayed by the artificial reality system according to the monitoring by altering the focal distance for virtual objects, text size, text/background color, light characteristics, and other suitable optical conditions. In some examples, user preferences for optical conditions can be determined according to the monitoring.

Abstract: Aspects of the present disclosure are directed to controlling optical parameters at a user's eye using an artificial reality system and tracked user conditions. For example, based on tracked user eye positioning, implementations can adjust the light that enters the user's eye to control an image shell generated at the user's eye. An image shell refers to the way light, that enters the eye, focuses on the retina of the eye. Example properties of an image shell include image shell centration, image shell curvature, image shell shape, etc. A user may focus on an object in an artificial reality environment (e.g., real-world object or virtual object) and light from the object can generate an image shell at the user's eyes. The image shell at the user's eyes can impact the user's vision and/or eye biology.

Abstract: A pipeline (e.g., a DevOps or DevSecOps pipeline) may include utilities corresponding to stages within the pipeline. A device may execute the pipeline on a version of a codebase, where the version of the codebase is associated with an immutable identifier of a version control management system. The device may generate metadata for one or more of the utilities of the pipeline based executing the pipeline on the version of the codebase. The device may store the metadata at a database, where the immutable identifier is designated as a primary key for the stored metadata. The device may verify the metadata at one or more gates of the pipeline based on a comparison of the stored metadata to a set of policy information associated with the one or more gates.

Abstract: An auto-focus head-mounted display (HMD) dynamically generates aberration-adjusted images based on measured accommodation of user's eye(s). An aberration-adjusted image is an image distorted to correct aberrations that would otherwise occur at a retina of the user due to image light passing through optics of the HMD. The aberration-adjusted image corrects the aberrations of the HMD and “accounts” for the aberrations of the eye so that the resulting retinal image is free of optical aberrations due to the HMD but preserves correct eye optical aberrations that are correlated with a current accommodative state of the eye.

The ROV includes a body configured to be operatively connected to the tether, and the sensor is configured to be operatively connected to the body, and configured to provide inspection information of the core shroud. The arm is configured to be operatively connected to the trolley. The ROV is configured to be operatively connected to the arm via the tether, and the tether is configured to provide vertical position information for the ROV relative to the outer surface of the core shroud.

Abstract: A multiplanar head mounted display (HMD) includes two or more artificial display planes for each eye located at optical distances that can be dynamically adjusted based on a location within a scene presented by the HMD that the user views. For example, a scene is presented on two or more electronic display elements (e.g., screens) of the HMD. A focal length of an optics block that directs image light from the electronic display elements towards the eyes of a user is adjusted using a varifocal system (e.g., an element that mechanically changes a distance between a lens system in the optics block and the electronic display element, an element that changes shape of one or more lenses in the lens system in the optics block, etc.) based on a location or object within the scene where the user is looking.

Abstract: A virtual reality headset displays a three-dimensional (3D) virtual scene and includes a varifocal element to dynamically adjust a focal length of an optics block included in the virtual reality headset based on a location in the virtual scene where the user is looking. The headset tracks a user's eyes to approximate gaze lines and determines a plane of focus for a frame of the virtual scene as the intersection of the gaze lines. The varifocal element adjusts the focal length of the optics block so the optics block is focused at the plane of focus, which keeps the user's eyes in a zone of comfort as vergence and accommodation change. Based on the plane of focus, the virtual reality headset may provide depth cues, such as depth of field blur, to planes in the virtual scene deeper in the user's field of view than the plane of focus.

Abstract: A head-mounted display (HMD) device includes a plurality of deformation sensors attached to a liner formed around a periphery of a HMD, adopted for direct or indirect contact a user's face. The deformation sensors measure deformations of the liner caused by movement of an upper portion of a user's face when the user is wearing the HMD. The deformation sensors are strain gauges embedded in or otherwise coupled to the liner of the HMD. The sensors translate muscle movements of the upper face of the user to changes in the bending strain and radius of curvature on the surface of the strain gauges. The HMD includes a module that reconstructs and projects a facial animation model of the user based on signals from the deformation sensors while the HMD is in use by the user.
