Abstract: In particular embodiments, a computing system may capture access a set of depth measurements and an image of a scene generated using one or more sensors of an artificial reality device. The system may generate, based on the image, a plurality of segmentation masks respectively associated with a plurality of object types. The system may segment, using the plurality of segmentation masks, the set of depth measurements into subsets of depth measurements respectively associated with the plurality of object types. The system may determine, for each object type, a three-dimensional (3D) model that best fits the subset of depth measurements corresponding to the object type. The system may refine, using 3D models determined for the plurality of object types, the subsets of depth measurements respectively associated with the plurality of object types and use refined depth measurements for mixed reality rendering.

Abstract: A maze-based switch generally having three functional blocks is disclosed. The first functional block handles communications by accepting an entered maze pattern from an external system controller and outputting the entered maze pattern (and optionally its directional complement) to the second functional block. The second functional block stores the maze pattern (and optionally its directional complement) to a permanent storage element and outputs the stored, entered maze pattern and its directional complement to a series of transistors in the third functional block. The third functional block is an electronic maze in which a correct maze pattern and its directional complement must be received by the transistors for the transistors to pass electrical power through the electronic maze to a connected element. The third functional block may alternatively be implemented with optical elements, optoelectronic elements, microelectromechanical elements, or elements formed by other microsystem technologies.

Abstract: A new cultivar of Cordyline australis, ‘Seipin’, characterized by its foliage that exhibits greyed purple centers and bright pink margins.

Abstract: A vibration isolator grommet comprises a sleeve and an annular elastomeric element. The sleeve has a cylindrical portion with a radially outwardly extending flange at one end thereof. The elastomeric element has a flange underlying the flange on the sleeve, a cylindrical portion telescoped over the cylindrical portion of the sleeve, and a radially inwardly extending portion initially underlying the cylindrical portion of the sleeve but movable radially outwardly upon axial advancement of the sleeve relative to the elastomeric element to lock the grommet in a workpiece.

Abstract: A vehicular MacPherson strut with piston comfort valving for accommodating short and rapid wheel movement on recoil only. A bypass valve disk is spring biased against a valve seat on a rebound chamber face of the piston head. The disk, seat and spring construction provides restricted flow followed by blow off on compression. On recoil, the disk provides bypass flow at stroke beginning, and flexes thereafter to stop bypass flow and restrict flow thereafter to restriction passages.
