| 20090185214 | Systems and Methods for Print Resource Management - Systems and methods consistent with some embodiments presented provide methods for print resource management. In some embodiments of methods for print resource management print data comprising PDL data may be parsed to identify reusable resources in the print data. The reusable resources may be converted to a common internal format and stored. In some embodiments, reusable resources may be rendered to obtain a rendered version of the reusable resource, which may be stored. In some embodiments, the stored rendered version or a rendered form of the stored formatted version of the reusable resource may be used in a bitmap image for a page whenever the reusable resource is referenced during the creation of the bitmap image for the page. | 07-23-2009 |
| 20100053179 | Systems and Methods for Framebuffer Management - Methods for managing a framebuffer in a single memory pool comprising frame buffer memory and display list memory on printing devices are presented. In some embodiments, a method for managing at least one pixmap corresponding to an image using equal sized blocks allocated to the pixmap from a memory pool comprises: receiving a request for at least one scanline in the image; securing a pointer to at least one block from the memory pool in response to the request for the at least one scanline, if memory blocks are available in the memory pool; and applying at least one of a plurality of memory freeing strategies, if there are no memory blocks available in the memory pool. | 03-04-2010 |
| 20100060934 | Systems and Methods for Optimal Memory Allocation Units - Methods for determining an optimal memory allocation unit size for a framebuffer in a single memory pool comprising frame buffer memory and display list memory on printing devices are presented. In some embodiments, a method for determining an optimal allocation unit size for memory allocation units allocated from a memory pool in response to a memory allocation request for a pixmap comprises determining the amount of unutilized memory when the pixmap is stored using a plurality of memory allocation unit sizes, wherein the memory allocation unit sizes are an integral multiple of a base memory allocation unit; and selecting a memory allocation unit size from the plurality of memory allocation unit sizes based on criteria related to the amount of unutilized memory. | 03-11-2010 |
| 20100079809 | Systems and Methods for Optimized Printer Throughput in a Multi-Core Environment - Systems and methods consistent with some embodiments presented provide methods for the concurrent generation and parallel rasterization of at least one display list in a memory pool comprising frame buffer memory and display list memory, wherein the display list comprises a plurality of equal sized display list blocks, the method comprises: monitoring the completion status of the display list blocks; monitoring the availability of rasterization processes; assigning a completed display list block to an available rasterization process; and rasterizing the display list block using the available rasterization process. In some embodiments, rasterization processes may run concurrently and operate on distinct blocks corresponding to distinct bands. Rasterized display list blocks are returned to the memory pool. In some embodiments, each concurrently executing rasterization process may execute on a distinct core of a multi-core processor. | 04-01-2010 |

| 20090025738 | Smokeless Tobacco Composition - The invention provides a process for preparing a tobacco composition suitable for use as a smokeless tobacco composition, the process including: providing a slurry comprising water and a tobacco material, the slurry comprising at least about 75% by weight water, based on the total weight of the slurry; heating the slurry to a temperature of at least about 60° C. for a time sufficient to pasteurize the tobacco material; adding an amount of a base to the slurry sufficient to raise the pH of the slurry to at least about 8.5, thereby forming a pH-adjusted slurry; and continuing to heat the pH-adjusted slurry to a temperature of at least about 60° C. for a time sufficient for the pH of the slurry to drop at least about 0.5 pH unit following the adding step. | 01-29-2009 |
| 20100300463 | THERMAL TREATMENT PROCESS FOR TOBACCO MATERIALS - A method of thermally processing a tobacco material is provided, the method including the steps of (i) mixing a tobacco material, water, and an additive selected from the group consisting of lysine, glycine, histidine, alanine, methionine, glutamic acid, aspartic acid, proline, phenylalanine, valine, arginine, di- and trivalent cations, asparaginase, saccharides, phenolic compounds, reducing agents, compounds having a free thiol group, oxidizing agents, oxidation catalysts, plant extracts, and combinations thereof, to form a moist tobacco mixture; (ii) heating the moist tobacco mixture at a temperature of at least about 60° C. to form a heat-treated tobacco mixture; and (iii) incorporating the heat-treated tobacco mixture into a tobacco product. Heat-treated tobacco composition prepared according to the method are also provided, such as heat-treated smokeless tobacco composition comprising a tobacco material, water, flavorant, binder, and filler, the heat-treated smokeless tobacco composition having an acrylamide content of less than about 2000 ppb. | 12-02-2010 |
| 20110048434 | THERMAL TREATMENT PROCESS FOR TOBACCO MATERIALS - A method of preparing a tobacco material for use in a smoking article is provided, including (i) mixing a tobacco material, water, and an additive selected from the group consisting of lysine, glycine, histidine, alanine, methionine, glutamic acid, aspartic acid, proline, phenylalanine, valine, arginine, di- and trivalent cations, asparaginase, saccharides, phenolic compounds, reducing agents, compounds having a free thiol group, oxidizing agents, oxidation catalysts, plant extracts, and combinations thereof; (ii) heating the mixture; and (iii) incorporating the heat-treated mixture into a smoking article as a smokable material. A smoking article in the form of a cigarette is also provided that includes a tobacco material pre-treated to inhibit reaction of asparagine to form acrylamide in mainstream smoke. Upon smoking, the smoking article is characterized by an acrylamide content of mainstream smoke that is reduced relative to an untreated control smoking article. | 03-03-2011 |
| 20110061666 | Smokeless Tobacco Composition - A smokeless tobacco product configured for insertion into the mouth of a user of the product is provided, the tobacco product including a water-permeable pouch containing a tobacco formulation, the tobacco formulation including a tobacco material and a plurality of microcapsules dispersed within the tobacco material, the plurality of microcapsules including an outer shell encapsulating an internal payload. The internal payload may include an additive such as water, flavorants, binders, colorants, pH adjusters, buffering agents, fillers, disintegration aids, humectants, antioxidants, oral care ingredients, preservatives, additives derived from herbal or botanical sources, and mixtures thereof. Microencapsulated flavorants include tobacco-containing flavorants, such as tobacco extracts or a particulate tobacco material, sweeteners (e.g., sweeteners containing neotame), and vanillin (optionally in a complexed form). | 03-17-2011 |
