Abstract: According to one embodiment, a method, computer system, and computer program product for modifying an object being 3D printed using augmented reality is provided. The present invention may include analyzing shape, dimensions, and/or axis of the object being 3D printed; mapping at least one part of one or more of a user's appendages to at least one portion of the object being 3D printed; tracking movements of the at least one mapped part of the one or more of the user's appendages; and modifying the at least one portion of the object being 3D printed based on the tracked movements of the at least one part of the one or more of the user's appendages.

Abstract: Closure devices for sealing a puncture and methods of sealing a puncture are described herein. A closure device may be used to position a sealant in a puncture. The sealant may be provided in a sheath which is retracted to expose the sealant in the puncture. A support member may be advanced to compress the sealant. The device may have a lock that prevents the support member from advancing prematurely. The lock may be unlocked when the sheath is at least partially retracted. The device may have an actuator that controls movement of the sheath and the support member. The lock may remain in a locked position until the sheath is at least partially retracted.

Abstract: Described are mechanisms for multi-nozzle additive manufacturing. The mechanisms include a three-dimensional printer including a primary print head with a primary nozzle. The three-dimensional printer further includes a nozzle print head configured to print different nozzles for additive manufacturing of an object. The three-dimensional printer further includes a secondary nozzle printed by the nozzle print head, and the three-dimensional printer is configured to print the object using the primary print head, the primary nozzle, and the secondary nozzle.

Abstract: An electric candle comprised of an electric lamp supported on a cylindrical casing above a base, said cylindrical casing having conductive strips connected to a power supply in said base and controlled by a switch means consisted of a spring coil around a conductor, said base having a sound pick up, a sound producing means at the inside, wherein making a sound causes said sound pick up to connect the electric circuit permitting said lamp bulb and said sound producing means to give light and sound respectively; blowing a stream of current through vent holes on said lamp cap causes said switch means to cut off the electric circuit permitting said lamp bulb and said sound producing means to stop giving light or sound.
