20100288196 | Apparatus for forming a flexible nanostructured material for photovoltaic panels - Provided is an apparatus for manufacturing a composite material consisting of a flexible substrate and a multilayer nanostructured PV-active film supported by the substrate. The apparatus comprises a sealable chamber, the cylindrical inner wall of which is used as a support for a flexible substrate. The chamber contains a rotating crucible having a recess in its center and flat margins. The apparatus is provided with a power laser capable of generating an annular beam focused on the aforementioned flat surface. In operation, a nanoparticle-containing colloidal solution is supplied to the crucible. During rotation, the solution moves to the flat margins where it forms a thin layer that is evaporated by means of the annular laser beam. As the solution evaporates, the nanoparticles, which remain on the surface, fly out by inertia from the edges of the crucible to the flexible substrate. The deposition process can be controlled so that the deposited layers form a PV-active film. | 11-18-2010 |
20100291725 | Method of forming a flexible nanostructured material for photovoltaic panels - An efficient and low-cost method is intended for forming a flexible nanostructured material suitable for use as an active element of a photovoltaic panel. The method consists of evaporating a colloidal solution, which contains nanoparticles of various sizes and/or masses, from a flat surface of a rotating body on which the solution forms a thin and easily vaporizable layer, and simultaneously releasing the nanoparticles from the solution for their free flight through a gaseous medium toward the flexible substrate. As a result, the particles of different sizes and/or types of material are deposited onto the flexible substrate in a predetermined sequence that corresponds to the magnitude of resistance experienced by the nanoparticles during their free flight. In this method, the final, flexible nanostructured material is formed as a multilayer nanostructured film in which the nanoparticles of larger size and greater density are deposited onto the flexible substrate first and thus are located under the nanoparticles of smaller size and smaller density. | 11-18-2010 |

20130297058 | DECOMPOSITION OF 3D GEOMETRY INTO DEVELOPABLE SURFACE PATCHES AND 2D CUT PATTERNS - Embodiments disclosed herein provide techniques for decomposing 3D geometry into developable surface patches and cut patterns. In one embodiment, a decomposition application receives a triangulated 3D surface as input and determines approximately developable surface patches from the 3D surface using a variant of k-means clustering. Such approximately developable surface patches may have undesirable jagged boundaries, which the decomposition application may eliminate by generating a data structure separate from the mesh that contains patch boundaries and optimizing the patch boundaries or, alternatively, remeshing the mesh such that patch boundaries fall on mesh edges. The decomposition application may then flatten the patches into truly developable surfaces by re-triangulating the patches as ruled surfaces. The decomposition application may further flatten the ruled surfaces into 2D shapes and lay those shapes out on virtual sheets of material. A person, or machinery, may cut out those shapes from physical sheets of material based on the layout. | 11-07-2013 |
