Abstract: Magnetic display devices include low-density silica coated magnetic and nonmagnetic particles. In a one-particle system, low-density silica coated magnetic particles coated by a sol-gel process are used in combination with non-magnetic particles. In a two-particle system, low-density silica coated magnetic particles coated by a sol-gel process are used in combination with low-density silica coated non-magnetic particles. Display devices employing silica coated magnetic particles minimize the tendency of the magnetic particles to aggregate. Silica coated magnetic particles in a display device results in a magnetic display with improved image stability. Low-density silica coated magnetic particles in a display device allow for particles to move easily through a dispersion fluid in response to a magnetic field.

Abstract: A system and method of evaluating the required operating capacities for each production function for each consolidation configuration of distributed print shops in an enterprise so that the most appropriate print shop consolidation options can be selected. Operating capacities of each production function for processing print jobs at each shop is initially determined on the basis that the print jobs can originate and be processed at the same print shop. The operating capacities are modified to take into account scenarios in which the print jobs can originate at each print shop and can be transported to each other print shop for processing. The determined maximum operating capacities at each shop can be mapped out for each possible configuration of consolidating a selected number of print shops into a selected number of consolidated shops.
