Abstract: A system includes a placement head with at least one printing nozzle configured to pick up and detachably hold at least one biological organism; an image acquisition system including a visual inspection system configured to identify at least one target biological organism to be picked up by the printing nozzle of the placement head in a first location, and identify at least one second location for deposit of the at least one target biological organism, wherein the first location is different from the at least one second location; and a robotic motion system that moves the placement head, based on input from the visual inspection system and a distance identification system, from the first location to the at least one second location, such that the placement head deposits the target biological organism at the at least one second location.

Abstract: Reinforced nuts comprise a polymer nut body and a metal casing fitted to an outer surface of the nut body. In some embodiments, the metal casing can cover the top of the polymer nut body and comprise a drive opening so that the casing carries a portion of an applied torque when the nut is being tightened. In other embodiments, the metal case can cover a portion of the bottom surface of the polymer nut body. Reinforced nuts can also comprise a cylindrical metal sleeve that is embedded in a polymer nut body. The metal sleeve can be solid, porous, comprise holes, or be a mesh. The reinforced nuts have an increased strength relative to nuts that are not reinforced and can thus handle a greater load when they nuts are being tightened.
