Patent number: 11418683Abstract: An image processing system and method provide for receiving a digital document page to be printed. The page includes a background region for which no color is specified. A user is presented with an option to select a print medium from a set of print media of different colors and to select an option for a color of the selected print medium be used as a color of a background layer of the digital document page. When the option is selected, a background layer is inserted into the page. A print job incorporating the processed digital document page is output to an associated printer that is configured to convert the color of the background layer to colorant values that use the print media as a colorant for rendering at least a part of the background region.Type: GrantFiled: July 14, 2021Date of Patent: August 16, 2022Assignee: XEROX CORPORATIONInventors: Frederick J.

Patent number: 6117125Abstract: A method for predetermining the controlled and uniform discharge rate of a fluid from a single lumen tubular body having passageways radially extending through the wall of the tubular body has been developed and is described. The method involves predetermining such parameters as the transverse cross-sectional areas of the passageways extending through the wall of the tubular body, the spacing of the passageways, the pressure at each of the passageways, and the rate of flow at each of the passageways. One specific preferred application of such a tubular body is an infusion catheter for delivering various fluids to designated areas of the body for either a therapeutic treatment and/or diagnostic purposes. For example, such a catheter may be adapted to deliver controlled and uniform quantities of thrombolytic agents, chemotherapeutic agents as well as such diagnostic agents as fluorescent dyes and radioactive agents.Type: GrantFiled: May 2, 1996Date of Patent: September 12, 2000Assignee: Cook IncorporatedInventors: Leo Rothbarth, Frank J.
