Abstract: A method and apparatus for additive manufacturing is provided whereby a curtain of powder is provided adjacent a vertically oriented build plate, and a laser melts or sinters the powder over a region of the build plate. The curtain of powder is moved relative to the build plate to maintain the same distance between the curtain and the previously deposited layer, and the process repeated to provide a three dimensional structure on the build plate.

Abstract: An additive manufacturing apparatus includes: a coater including: at least one trough including a plurality of side-by-side deposition valves.

Abstract: The present invention relates to a solar cooking apparatus, comprising: a first solar reflector; a second solar reflector; a solar collection element; and a solar collection element holder, wherein the first solar reflector and the second solar reflector are concave, and symmetrically arranged and aligned with a solar collection element axis, the reflectors having a up to a 360° range of motion around a plane perpendicular to the solar collection element axis, and focusing radiation at the solar collection element, which rapidly heats when the first and/or second solar reflectors are in an opened position, the first and second solar reflectors shield the solar collector when in a closed position. The solar cooking apparatus is adjustable and, in some embodiments, portable.

Abstract: A system for producing a depiction of an image is provided. The present invention includes camera operable to capture an image and a laser projector operable to project a laser beam in an x and y direction. The present invention further includes a computer having a microprocessor and a memory. A software may be saved on the memory and may operate the computer to scan the image to locate edges of objects depicted in the image and direct the laser projector to project the laser beam along x and y coordinates of a plane. The x and y coordinates outlines the edges of the objects and thereby forms the depiction of the image.

Abstract: A method of fabricating a lead for use in conjunction with a semiconductor device and the lead. A surface is provided which is disposed on a semiconductor substrate and has a via (5) with electrically conductive material (9) therein extending to the substrate. A lead is formed on the surface having an optional barrier layer (11) disposed on the surface and contacting the electrically conductive material (9). An electrically conductive metal layer (13) is formed which is disposed over and contacting the barrier layer (11) and has sidewalls. An anti-reflective coating (15) is formed on the electrically conductive metal layer (13) remote from the barrier layer (11). The electrically conductive metal layer (13) is encapsulated between the barrier layer (11) and the anti-reflective layer (15) with a composition taken from the class consisting of TiN, W, Ti, and Si3N4.
