Abstract: A three dimensional printing system includes a print engine, a storage system, and a controller. The controller is configured to (1) receive a build order defining a plurality of three dimensional articles to be manufactured, (2) allocate partitions for receiving the plurality of the three dimensional articles within the storage system, (3) operate the print engine to fabricate the three dimensional articles, and (4) transfer the three dimensional articles to the partitions as they are built.

Abstract: A three dimensional printing system includes a resin vessel, a light engine, and a fluid spill containment vessel. The resin vessel is for containing resin and has a transparent sheet on a lower side that provides a lower bound for the resin. The light engine is disposed below the resin vessel for projecting pixelated light up through the transparent sheet. The fluid spill containment vessel is disposed between the resin vessel and the light engine to capture resin that spills from the resin vessel. The fluid spill containment vessel includes a housing for containing the spilled resin, a transparent window for allowing the pixelated light to project up through the fluid spill containment vessel and to the transparent sheet, and a fluid barrier wall surrounding at least part of the clear window and configured to reduce an amount of spilled resin required to occlude the pixelated light.

Abstract: A growth module for growing biomass comprising a plurality of growth columns connected together. Each growth column comprises a vertically oriented, hollow, translucent tubular body having input lines for introducing air, gas and nutrients into each column through the top thereof. The growth columns are frictionally mounted upon a bottom manifold that is configured for receiving gravity induced flow of biomass from said plurality of growth columns.

Abstract: The present invention is a system for optimizing production of biomass. The system contains one or more growth modules under a shading element that diffuses light. Each of the growth modules has a plurality of vertical growth columns arranged on a bottom manifold. The biomass is grown within a liquid growth medium held within each of the vertical growth columns until it reaches a desired growth. The biomass is then harvested through gravitational flow of the biomass and the liquid growth medium out of the bottom of each growth column. The bottom manifold collects gravitational flow of the biomass and liquid growth media from each growth column and aggregates the output of each individual column into a collective output of the growth module.

Abstract: The invention provides a method of preparing a blast hole which method comprises the steps of: drilling a blast hole; placing explosives in the blast hole; filling the blast hole with a stemming material comprising a cement composition and water wherein the weight ratio of water to solids content of the stemming material is at least about 1:1.

Abstract: A portable computing device, including a keyboard illumination device and system may include a light emitter housing incorporated into the hinge element of a portable computing device. The light emitter housing may include an aperture and a light emitter and may be configured to illuminate a keyboard while keeping the source of the emitted light hidden from the user and others who may be in the vicinity of the portable computing device. The light emitter, which illuminates the keyboard, may be driven by a different light source than the light source that illuminates a display panel of the portable computing device. It follows that the brightness of the light emitter may be adjusted without having any effect on the brightness of the display panel.
