Abstract: Methods, devices, and systems for forming atomically precise structures are provided. In some embodiments, the methods, devices, and systems of the present disclosure utilize a scanning tunneling microscope (STM) to remove portions of a monolayer of atoms or molecules from a crystalline surface to form atomically precise structures. The STM is utilized to both image the sample and remove the desired portions of the monolayer of atoms or molecules. In some instances, the lattice structure of the crystalline surface is utilized as a coordinate system by a control system of the STM to facilitate the automated removal of specific atoms or molecules from the crystalline surface.

Abstract: A solution containing randomized nanotubes is introduced into a channelized mold and the solution is dried resulting in a number of parallel nanotubes stretched across the walls of the channel. In one embodiment, the channels are open along their longitudinal axis and that opening is covered with a material, such as silicon. The solution is allowed to dry, preferably at room temperature, and as it recedes from the channel the receding solution tends to stretch certain of the nanotubes across the channel so that they become attached to the opposite walls of the channel. By varying the shapes and width of the channel sides various controlled nanotube lengths can be achieved. The mold, with the constructed nanotubes, can be positioned to mate with another structure for the transfer of the nanotubes to the second structure.

Abstract: A system and method for generating real time calligraphic curves from an input source. The input can be a stylus and the angle of attack of the line with respect to a surface can be fixed or variable. The calligraphic curve can have a fixed or variable width which can be point by point edited to form a new calligraphic curve.

Abstract: A system and method in which derived graphic elements are generated automatically upon changes made to the defining graphic elements or generation parameters. A user need only modify the defining element(s) and the system will eliminate any originally derived elements and substitute therefor any newly created derived elements. The system is arranged to inhibit the generation of the derived elements until all of the changes associated with all of the defining element(s) have been made. The regeneration of the derived elements is performed once even if multiple defining elements have been modified.

Abstract: A video graphics system and method for creating variable width lines such that the lines may be easily edited. As a line image is created, a center point of that image along its length is temporarily established having width information at various points. This width information is used to create an outline of image of the desired shape, the outline having point data spaced at intervals. This point data can then be edited by a user to create different shapes. In situations where a pressure sensitive stylus is used to create the variable length line, a look-back technique is employed to insure that the line remains wide at the end point even though the user is reducing pressure as the system is removed from the pad.

Abstract: A system and method for generating self-overlapping calligraphic images from an input source. The input can be a stylus and the angle of attack of the line with respect to a surface can be fixed or variable. The calligraphic image can have a fixed or variable width which can be point-by-point edited to form a new calligraphic image. The system has the ability to expand a calligraphic image with overlapping strokes and subsequently edit the image.
