Abstract: An artificial intelligence framework is described that incorporates a number of neural networks and a number of transformers for converting a two-dimensional image into three-dimensional semantic information. Neural networks convert one or more images into a set of image feature maps, depth information associated with the one or more images, and query proposals based on the depth information. A first transformer implements a cross-attention mechanism to process the set of image feature maps in accordance with the query proposals. The output of the first transformer is combined with a mask token to generate initial voxel features of the scene. A second transformer implements a self-attention mechanism to convert the initial voxel features into refined voxel features, which are up-sampled and processed by a lightweight neural network to generate the three-dimensional semantic information, which may be used by, e.g., an autonomous vehicle for various advanced driver assistance system (ADAS) functions.

Abstract: An additive manufacturing apparatus (10) includes (a) a light polymerizable resin unit comprising a surface on which a light polymerizable resin can be supported; (b) a light engine (17) configured to illuminate a region of the light polymerizable resin unit; (c) a carrier platform on which an object can be produced; (d) a drive assembly operatively associated with the carrier platform for advancing said carrier platform (12) and said light polymerizable resin unit away from one another as said object is produced; (e) a purge chamber (300) surrounding at least a portion of said light engine (17); and (f) a purge gas in said purge chamber, or a purge gas supply operatively associated with said purge chamber (300).

Abstract: A stereolithography apparatus includes a light transmissive window defining a build region in which a polymerizable resin can be supported, the window characterized by a transmission spectra curve having a low transmissivity region between first and second high transmissivity regions; a carrier platform positioned above the window; a drive operatively associated with the carrier platform and the window and configured for advancing the window and the carrier platform away from one another; an ultraviolet light source positioned beneath the window; at least one infrared heat source positioned beneath the window; at least one temperature sensor operatively associated with the build region and configured to sense (directly or indirectly) the temperature of a polymerizable resin in the build region; and a temperature controller operatively associated with the temperature sensor and the infrared heat source, the controller configured to intermittently activate the infrared heat source to an elevated temperature at

Abstract: A gliding board may have less resistance to bending in portions within one or both binding mounting regions as compared to portions at or near ends of the binding mounting regions. Some embodiments provide for increased ability to store and release energy when performing certain maneuvers with the board, such as nose presses, ollies and similar moves. Regions of greatest stiffness may be arranged at outer ends of the binding mounting regions, and may be arranged along lines that are transverse to a longitudinal axis of the board. Alternately, a board may include heel and toe convex portions in the heel and toe side edges that are offset along the board length, e.g., so that the heel convex portions are closer to each other and to a longitudinal board center than the toe convex portions.

Some embodiments provide for increased ability to store and release energy when performing certain maneuvers with the board, such as nose presses, ollies and similar moves. A board may have a concave portion in the top surface located at both the forward and rear binding mounting regions, and convex portions may be located in the top surface between the binding mounting regions as well as forward of the forward mounting region and rearward of the rear mounting region. In another arrangement, concave portions may be located in the bottom surface of the board under the binding mounting regions so as to give desired bending characteristics to the board.
