    Abstract: A system and methods for a CODEC driving a real-time light field display for multi-dimensional video streaming, interactive gaming and other light field display applications is provided applying a layered scene decomposition strategy. Multi-dimensional scene data is divided into a plurality of data layers of increasing depths as the distance between a given layer and the plane of the display increases. Data layers are sampled using a plenoptic sampling scheme and rendered using hybrid rendering, such as perspective and oblique rendering, to encode light fields corresponding to each data layer. The resulting compressed, (layered) core representation of the multi-dimensional scene data is produced at predictable rates, reconstructed and merged at the light field display in real-time by applying view synthesis protocols, including edge adaptive interpolation, to reconstruct pixel arrays in stages (e.g. columns then rows) from reference elemental images.

    Abstract: A reverse shoulder prosthesis includes a humeral adapter tray (300) configured to sit near a resected surface of a humerus, the humeral adapter tray (300) comprising: a cavity (302); a central bore; and a distal face (304) including a boss (310), the boss (310): (i) configured as an extension of the distal face, (ii) posteriorly offset from the central bore by at least 10 mm, and (iii) configured to engage a humeral stem; and a humeral liner (250) comprising: a distal rim (252) configured to sit within the cavity (302) of the humeral adapter tray (300); and a concave articulating surface configured to mate with a convex articulating surface of a glenosphere. Offsetting the reverse shoulder humeral adapter tray shifts the humerus in the posterior direction so as to result in better deltoid wrapping, more anatomic muscle tensioning, and larger muscle moment arms during both abduction and internal/external rotation.
