Patent number: 7983477Abstract: A method of generating a stereoscopic image is disclosed. The method includes defining at least two, three or more regions in a scene representing a region of interest, a near regions and/or a far region. This is followed by forming an image pair for each region, this image pair containing the information relating to objects in or partially in their respective region. The perceived depth within the regions is altered to provide the idea or best perceived depth within the region of interest and acceptable or more compressed perceived depths in the other regions. The image pairs are then mapped together to form a display image pair for viewing on a display device.Type: GrantFiled: July 2, 2009Date of Patent: July 19, 2011Assignee: The University of DurhamInventor: Nicolas Steven Holliman

Patent number: 7978386Abstract: A method of generating a holographic diffraction pattern and a holographic lithography system. The method involves defining at least one geometrical shape; generating at least one line segment to represent the at least one geometrical shape; calculating a line diffraction pattern on a hologram plane, including calculating the Fresnel diffraction equation for an impulse representing the at least one line segment with a line width control term and a line length control term; and adding vectorially, where there are two or more line segments, the line diffraction patterns to form the holographic diffraction pattern. The method and system enables holographic masks to be generated without creating a physical object to record. The required shapes or patterns are defined in terms of a three-dimensional coordinate space and a holographic pattern is generated at a defined distance from the shapes in the coordinate space.Type: GrantFiled: August 23, 2005Date of Patent: July 12, 2011Assignee: University of DurhamInventors: Alan Purvis, Richard McWilliam, Nicholas Luke Seed, Gavin Lewis Williams, Peter Anthony Ivey, Andrew Maiden, Simon Johnson

Publication number: 20100009095Abstract: The invention is directed toward the use of an atomizer to inject a coating material typically in the form of a liquid/solid particulate slurry into a sub-atmospheric pressure plasma to generate a high flux of excited coating forming material that permits the rapid deposition of a composite coating onto a substrate. The use of plasma discharges at reduced pressures results in the more efficient consumption of process precursors and gases, a reduced risk of explosion compared to atmospheric pressure processes and facilitates the removal of volatile components from the deposited composite coatings prior to their use.Type: ApplicationFiled: March 3, 2006Publication date: January 14, 2010Applicants: SURFACE INNOVATIONS LTD., UNIVERSITY OF DURHAMInventors: Luke John Ward, Jas Pal Singh Badyal
