Abstract: An additive manufacturing system may include an additive manufacturing apparatus on which a process of producing a three-dimensional object from a material can be performed; an additive manufacturing process controller operatively associated with the additive manufacturing apparatus; and a first memory device operatively associated with the additive manufacturing process controller. The first memory device may include first and second stable release process programs each comprising a first subset of operations executable by said process controller. The system may include a second memory device comprising another stable release process program comprising a second subset of operations executable by said process controller. The system may include a selector configured to choose one of the stable release process programs to run on said process controller when producing a three-dimensional object on the additive manufacturing apparatus.

Abstract: The present invention is a Miniature Vein Enhancer that includes a Miniature Projection Head. The Miniature Projection Head may be operated in one of three modes, AFM, DBM, and RTM. The Miniature Projection Head of the present invention projects an image of the veins of a patient, which aids the practitioner in pinpointing a vein for an intravenous drip, blood test, and the like. The Miniature projection head may have a cavity for a power source or it may have a power source located in a body portion of the Miniature Vein Enhancer. The Miniature Vein Enhancer may be attached to one of several improved needle protectors, or the Miniature Vein Enhancer may be attached to a body similar to a flashlight for hand held use. The Miniature Vein Enhancer of the present invention may also be attached to a magnifying glass, a flat panel display, and the like.
