Abstract: Systems and methods are described for providing an image validation module. The image validation mobile enables capture, enhancement, validation, and upload of a digital image to a networked computing service, applying criteria that correspond to image validation criteria used by the networked computing service. The image validation mobile may be executed on a mobile computing device, and may authenticate itself to the networked computing service to indicate that digital images have already been validated. The image validation module may provide feedback before, during, or after image capture to enable the capture of valid images, and may provide feedback before, during, or after image enhancement to allow issues that prevent a digital image from passing validation to be addressed.

Abstract: An example enclosure includes a base, a plurality of walls extending from the base, and a top disposed opposite the base and connected to at least one of the plurality of walls. The enclosure also includes a light assembly configured to illuminate an interior space of the enclosure. The light assembly includes a diffuser, a heat sink connected to the diffuser, a substrate connected to the heat sink, and a light source connected to the substrate. The diffuser may be connected to one of the top or the base such that the heat sink is spaced from the one of the top or the base. Additionally, the top is moveable toward the base to transition the enclosure from an expanded state to a collapsed state.

Abstract: An example enclosure includes a base, a plurality of walls extending from the base, and a top disposed opposite the base and connected to at least one of the plurality of walls. The at least one wall includes a light assembly configured to illuminate an interior space of the enclosure at least partly defined by the base and the plurality of walls. The top is moveable toward the base to transition the enclosure from an expanded state to a collapsed state. Additionally, the at least one wall includes a first panel and a second panel movable relative to the first panel. Further, the first and second panels extend substantially parallel to the base when the enclosure is in the collapsed state.

Abstract: Disclosed are various embodiments for performing automated color authoring for images of items having multiple color variations. A photographically captured source image of an item is obtained. The source image corresponds to one color variation of the item. A selection mask defining the item in the source image is obtained. A target image of the item corresponding to another color variation is generated by automatically transforming the item defined by the selection mask in the source image to the other color variation based at least in part on data obtained from multiple previous manual color variation transformations for multiple other items.

Abstract: A portable apparatus for forming pipe from helical convulsions of elongated sheet metal. A decoiler, rolling portion and pivot are mounted on a trailer, with a rigid frame extending from pivot and being laterally pivotable at the pivot in relation to the trailer. A forming head, cutoff saw, and dump table are mounted on the frame and pivotable therewith so that various diameters of pipe can be formed.

Abstract: An adjustable horn or mandrel for a spiral pipe forming machine. Such machines are made for continuously forming metal pipe from an elongated sheet of metal where the sheet is curled into adjacent helical convolutions in a multiple roll pipe forming head. The head includes a mandrel, and in accordance with the invention a mandrel mount is provided for vertical adjustment of the mandrel. The mandrel mount has opposite side supports sandwiching the mandrel and a motor mounted for raising and lowering the mandrel between the side supports. Raising and lowering is accomplished via a pair lead screws secured to the mandrel, each having a gear threadedly engaged thereon and which is driven by the motor. The mandrel is also horizontally adjustable.

Abstract: A multi-layer, spirally wound tube or pipe product with a substantially smooth inner wall having a single, helical corrugation and a corrugated exterior wall. The pipe has an inner pipe layer consisting of an elongated sheet of flat material curled into adjacent, helical convolutions and an outer pipe layer consisting of an elongated sheet of corrugated material curled into adjacent, helical convolutions about the inner pipe layer. The inner and outer pipe layers share a common helical seam. A single, continuous helical corrugation is located in the inner pipe layer along the helical seam, thereby causing the seam to be located within the single corrugation.

Abstract: A method and apparatus for the continuous manufacture of reinforced, spirally wound pipe having a generally smooth inner wall produced from an elongated flat sheet of ductile material, such as galvanized steel, and one or more narrow strips of ductile material. The sheet and strips are situated in rolls located at the entry end of a rolling apparatus which is constructed to form one longitudinal, generally trapezoidal reinforced impression in the sheet corresponding to each of the narrow strips. In the process of forming the impressions, rolling stands in the rolling apparatus first fashion a longitudinal, generally rectangular channel in the sheet corresponding to each strip as the sheet progresses through the rolling apparatus. At the same time, the strips are shaped into reinforcement elements having an extended, continuous portion and splayed legs extending outwardly from the edges of the continuous portion.

Abstract: A reinforced, spirally wound tube or pipe product shaped from an elongated sheet of ductile material formed into adjacent, helical convolutions. The pipe is impressed with at least one longitudinal impression which is trapezoidal in cross-section and formed at the same helix angle as the convolutions so that it is parallel to the juncture of adjacent convolutions. A conforming reinforcement element is located in the impression to strengthen the impression and form a closure of the mouth of the impression. The impression protrudes from the outer wall of the pipe, leaving the inner wall surface of the pipe generally smooth. Adjacent edges of the spiralled sheet are either welded or joined by a continuous lock seam.

Abstract: An apparatus and method for continuously forming multi-layer metal pipe from at least two elongated sheets of metal. One sheet is impressed with longitudinal corrugations in a rolling device and the second sheet, being uncorrugated, is then positioned contiguously upon the first, forming a multi-layer sheet. One or more removable modules is mounted in the rolling device to accurately align and guide the second sheet into position upon the first. Complementary portions of a single corrugation are then formed in the marginal edges of the multi-layer sheet and the sheet is spiralled into adjacent, helical convolutions in a pipe forming device, with the uncorrugated sheet forming the pipe interior. The adjacent convolutions are joined in a helical seam in the single corrugation by a seaming device located in the pipe forming device. In the primary embodiment of the invention, the seam is formed as a double lock seam along a neutral axis of the single corrugation.
