Abstract: A posterior cervical fixation system includes a facet lock comprising an elongate member having distal and proximal ends. A tapered wedge projects axially from the distal end and defines a wedge axis, the wedge being sized and configured for insertion into a facet joint of a cervical spine. The facet lock includes opposing first and second dovetail recesses. The system further includes a tubular guide having distal and proximal ends and a lumen extending therethrough along a central axis. The tubular guide has a plurality of dovetail projections extending exteriorly outwardly, each dovetail projection terminating in an engagement surface that is spaced respectively at a different radial distance from the central axis. Each dovetail projection is configured for individual releasable attachment to one of the facet lock first or second dovetail recesses to selectively space the wedge axis and the central axis at different distances for lateral mass screw placement.

Abstract: Optimizing viewing assets, such as three-dimensional (3D) virtual objects for mixed reality (MR), virtual reality (VR), or augmented reality (AR) environment visualization may involve obtaining a viewing asset, generating a decimation request for the obtained viewing asset, responsive to generating the decimation request, receiving a set of decimation files, based at least on the set of decimation files, generating a plurality of selectable options, receiving a user selection of an option, and outputting the selected option as a converted viewing asset. Disclosed examples may also include specifying a maximum file size, a minimum polygon count, a maximum polygon count, and a minimum number of renderable viewing assets on a target display platform. Disclosed examples may operate automatically, and may permit tailoring of a decimation recipe.

Abstract: A hooded garment comprises a torso portion, a hood portion attached to the torso portion and provided with a frontal face opening having a peripheral edge and a hood channel extending around at least a greater part of the peripheral edge, and a flexible drawstring extending through the hood channel. The drawstring is provided to adjust the effective perimeter of the peripheral edge of the face opening. The drawstring includes a middle portion slidably disposed in the hood channel, a first side portion extending from one side of the hood channel and a second side portion extending from another side of the hood channel. The first and second side portions are disposed outside the hood channel in the hood portion so that a greater part of each of the first and second side portions is hidden within or behind the torso portion.

Abstract: An insert for use with a sealing device having a flexible ring with a circumferentially extending channel which opens in an axial direction at one end of the ring. The channel is bounded by the ring's sidewalls which have external sealing faces engageable with the moving surfaces to be sealed. The insert is comprised of a seal-reinforcing ring having aa flat annular disk and an annular projection extending at least in one axial direction from the disk. The annular projection substantially corresponds in size and configuration to the cross-sectional size and configuration of the channel and is insertable into the channel. The disk defines radially extending seating surfaces disposed at the one end of the ring when the projection is inserted into the channel and limits the depth of the extension of the projection therein. The insert ring is designed with an axial projection extending in one direction away from the seating portion or disk or in opposite directions away from the disk.
