Abstract: Some embodiments herein are directed to head-mounted Virtual Retina Display (VRD) systems with actuated reflective pupil steering. The display systems include a projection system for generating image content and an actuated reflective optical architecture, which may be part of an optical combiner, that reflects light from the projection system into the user's eyes. The display systems are configured to track the position of a user's eyes and to actuate the reflective optical architecture to change the direction of reflected light so that the reflected light is directed into the user's eyes. The VRDs described herein may be highly efficient, and may have improved size, weight, and luminance such that they are capable of all-day, everyday use.

Abstract: One embodiment of a method for generating representations of scenes includes assigning each image included in a set of images of a scene to one or more clusters of images based on a camera pose associated with the image, and performing one or more operations to generate, for each cluster included in the one or more clusters, a corresponding three-dimensional (3D) representation of the scene based on one or more images assigned to the cluster.

Abstract: A portable holder for storing air guns and other hand tools is disclosed. In a preferred embodiment, the holder comprises: a generally-tubular body having two open ends, one of which is flared; a slit or gullet on one side of the body and extending longitudinally from the flared open end of the body partway down the body; and a plurality of magnetic discs or feet for removably, yet securely attaching the holder to a workstation having a ferrous surface. A related process for storing such tools comprises: orienting a generally tubular holder adjacent a workstation's metal side; removably affixing the holder to that metal surface by at least one magnet; slipping the particular tool into a flared end of the holder; and guiding a portion of the tool, such as an attached air hose or the tool handle, into a gullet of the holder to rest the tool and orient the hose or handle for easy retrieval of the tool from the holder.

Abstract: A versatile book is disclosed for hanging pneumatically actuated devices (e.g., airguns or spray guns). In the preferred embodiment, the versatile hook comprises: a hook body having a base with an annular section that defines a through-space corresponding to the shape of the pneumatic device's cylindrical extension tube or barrel; a hook-shaped extension attached to the body; and, positioning-and-mounting means for selectively positioning the hook, around and along the barrel, and thereafter mounting the body in a temporarily fixed position onto the barrel, with the hook-shaped extension facing towards or away from the discharge nozzle. Upon loosening a bolt, the preferred hook can be reoriented.
