Pages of books are copied without distortion due to curvature of the page near the book binding or the distortion in a copied page is corrected using the spacing of equidistant bars on tape strips applied to the top and bottom edges of a page before copying. The tape is preferably transparent and rather narrow and easily attached to a page to be copied. The first step in the distortion correction procedure is to locate the bars at the top and bottom of the page. The distortion of the spacing between the imaged bars is computed based on the known distance between the equidistant bars. The computed distortion of the spacing is then input to a distortion correction algorithm. The output of the distortion correction algorithm generates a corrected image. This image may also optionally delete the bars so that they are not printed in the copy. The corrected image is then copied.

A rotatable drum useful in the manufacture of vehicle tires. A plurality of segments collectively define the outer circumferential surface of the drum. These segments are divided into two sets, one set being disposed on each of the opposite sides of a transverse center plane of the drum, the center plane being oriented normal to the rotational axis of the drum. The two sets of segments are mounted for selective positioning thereof axially of the drum from a location external of the drum to adjust the overall working width of the drum. Further, the segments are selectively positionable between expanded positions radially of the rotational axis of the drum to provide a relatively continuous circumferential outer surface of the drum for the layup of a tire carcass thereon, and collapsed positions radially of the drum to permit the removal of a formed toroidal carcass from the drum. Movement of the plurality of segments of each of the two sets of segments radially of the rotational axis of the drum is effected by "slaving" the two sets of segments off a central mechanism which controls the radial positions of all the segments simultaneously and equidistantly from the rotational axis of the drum, while further providing for axial movement of the two sets of segments relative to one another while the segments are positioned at any given radial location of the segments.

Systems and methods for generating 2D texture coordinates for 3D surfaces meshes may assign initial 2D texture coordinates to each node within a mesh using dead reckoning, compute a conformal mapping solution to revise the texture coordinates dependent on the initial mapping, and store the texture coordinates for subsequent use in a graphics application (e.g., applying a texture and / or re-meshing a surface). The methods may include designating one node as the origin, determining the shortest distance from each other node to the origin, and computing texture coordinates for each other node in order of increasing distance to the origin. The dead reckoning operation may compute texture coordinates of each node dependent on the distance and direction of a vector formed between the node and a neighbor node to which texture coordinates have already been assigned. Isometric terms reflecting stretching or compression may be introduced following convergence by the conformal mapping.
