A pseudo-random steganographic camouflage includes a graphic design printed or painted as camouflage on an outer side of a substrate like Mylar thermal blanket sheets, uniforms, and adhesive tapes. The graphic design is uniquely generated from pseudo-random noise in four overlaying colors that each begin as a raster of randomly generated noise CDMA encoded with a PRN and a message in a standardized tile size. E.g., gray, green, tan, and brown colors natural for concealment applications are each masked by two-tone image contrast rasters. The four results are mixed in groups together with a monochrome mixing mask to produce a whole tile of concealment camouflage that will conjoin seamlessly within arrays of such tiles. A further refinement visually adds a distorted-grid mesh-texture to the pseudo-random steganographic camouflage, and even faint watermarks of commercial trademarks.

A concealment substrate manufacturing process begins by printing or painting a graphic design as camouflage on substrates like mesh-textured uniforms, military equipment, Mylar thermal blanket sheets, adhesive tapes, etc. The graphic design is uniquely generated from pseudo-random noise in four overlaying color pigments that each begin as a raster of randomly generated noise in a standardized tile size. E.g., gray, green, tan, and brown colors natural for concealment applications are each masked by two-tone image contrast rasters. The four results are mixed together in groups with a monochrome mixing mask to produce a whole tile. Such concealment camouflage tile conjoins seamlessly on-edge within other arrays of identical tiles. One variation adds a distorted-grid mesh-texture overly texture to the concealment camouflage, and even a faint watermark related to a commercial trademark.

An operation unit is provided on a front side of the image forming apparatus. A document feeding portion feeds a document supported by a document supporting portion in a document feeding direction from a front side of the image forming apparatus toward the rear side of the image forming apparatus. A document discharge portion discharges the document in a document discharge direction from the rear side toward the front side. The operation unit is disposed on one side with respect to an apparatus center of the image forming apparatus in a left-right direction orthogonal to a direction from the front side to the rear side. A conveyance center of the document feeding portion in the left-right direction is disposed on the other side with respect to the apparatus center in the left-right direction.

A scanner, specifically for scanning antique books, comprising a beam to which is attached a slide bearing guide and a stepper motor connected to a transmission, wherein to the opposite end of the beam a similar bearing-supported freely rotating gear is attached, wherein between the said gears runs a toothed belt two ends of which are attached to slide bearing, to which guide and motor are attached with a connector in-between, wherein motor is linked to a screw by means of a toothed belt. A method of scanning antique books consists in moving a linear camera over the scanned book in three axes, travelling over the scanned object (a), travelling along the vertical axis (b) and rotating around its axis (c).

A substrate inspection device and method are disclosed. The substrate inspection device includes a conveyance stage for carrying the substrate on its surface; a region scanning camera located at a first side of the conveyance stage, provided to be opposite to the surface, and configured for inspecting standard specification of the substrate; a line scanning camera located at the first side of the conveyance stage, provided to be opposite to the surface, and configured for inspecting edge line and size of the substrate; and a light source located at a second side of the conveyance stage opposite to the first side, configured for irradiating light rays onto the substrate, so as to be utilized by the region scanning camera and the line scanning camera for inspecting the substrate.
