Latest Patents

Cooper's latest patents describe innovative imaging systems and methods. In one aspect, an ink layer containing an electrorheological fluid composition is formed on a surface. This composition includes a suspension of colorant particles dispersed in an electrically insulating carrier fluid. A charge image is projected onto the ink layer, selectively forming charge-stiffened regions that adhere to the electrically insulating layer. These regions represent the respective areas of the projected charge image. Non-charge-stiffened components of the ink layer are physically separated from the charge-stiffened regions. Portions of the ink layer are then electrostatically transferred to a receptor substrate, enhancing the imaging process.
