20080246765 | Method and apparatus for constraint-based texture generation - A method and apparatus for texture mapping a surface. The method is applicable to texture mapping either a two-dimensional representation (image) of a three-dimensional surface as well as a three-dimensional computer model of a three-dimensional surface, such as a triangular wire mesh model. In one embodiment, the texture mapping process involves user-specification of a plurality of constraints, including texture flow constraints, texture discontinuities, and surface underfolds. A triangular wire mesh model of the surface to be textured is generated. The mesh allows a continuous texture distribution to be specified as a linear interpolation of texture values at the triangular vertices. User-specified constraints are preserved as edges within the triangular mesh. The triangular mesh is used to compute a weighted energy functional expressed in terms of nodal texture values. The global value of this functional serves as a measure of how closely the user-specified and physics-based constraints are met by a particular texture distribution. The optimal texture distribution is found by determining the set of nodal values which minimizes this functional, through an iterative process that is recursively applied to each nodal value using the results of a previous iteration. In accordance with one aspect of the invention, the results of previous optimizations may be used as the starting point for subsequent refinements of the texture distribution, in the event that greater levels of photorealisim are necessary. During this recursive procedure the triangular mesh is progressively refined using an adaptive subdivision procedure which allows local texture variations to be more accurately expressed whilst optimizing the overall mesh density against calculational efficiency. | 2008-10-09 |

The shell meshing area extracting portion extracts a shell-like space between the inner tetrahedral mesh and the triangular mesh on the surface of geometry model. The shell mesh generating portion generates the tetrahedral mesh in the overall shape to be meshed. | 2008-10-09 |

The system includes a collimated light source oriented to direct a collimated beam of light generated by the source towards a rotating image member, an image sensor for generating an image of a portion of the rotating image member from a portion of the collimated beam of light reflected by the rotating image member, an image differentiator for measuring a difference between a first image generated by the image sensor and a second image generated by the image sensor, and a release agent measurement generator that is coupled to the image differentiator to receive the difference between the two images and to generate a measurement of the release agent on the rotating image member. | 2008-10-09 |
20080246797 | Mobile Phone With An Internal Printer Having A Print Cartridge With A Media Drive Shaft - Provided is mobile phone having an internal printer. The phone includes a print cartridge having a housing with ink bearing structures and a printhead integrated circuit, and a capper fast with the housing to operatively cap the printhead integrated circuit. The cartridge also includes a lid and cover assembly for sealing engagement with the housing to protect the housing and capper, as well as a media drive shaft rotatably mounted to the housing for driving print media past the printhead. | 2008-10-09 |
20080246798 | PRINTER ARRANGEMENT WITH PRINTHEAD AND INK TRANSPORT ASSEMBLY - A printer arrangement having a printhead mounted on a carrier, the printhead connected to a printhead controller by means of encapsulated wire bonds. The arrangement also includes an ink supply manifold having a plurality of ink reservoirs for supplying the printhead with ink, and an ink transport assembly configured to facilitate purging of ink from the printhead when the assembly is in a cleaning position. | 2008-10-09 |
20080246799 | PRINTHEAD MAINTENANCE ASSEMBLY HAVING A CAPPER WITH A CONSTRICTION MEMBER - Provided is a printhead maintenance assembly having an ink manifold with a printhead, the manifold operatively supplying the printhead with ink, and a capper arrangement. The capper arrangement includes a capper operatively fitted to the manifold over the printhead, the capper defining a capper chamber with a constriction member splitting said chamber into an air inlet channel and a vacuum channel. The constriction member is located proximate the printhead to define a blast channel therewith between the inlet channel and the vacuum channel. | 2008-10-09 |
20080246800 | PRINTHEAD MAINTENANCE ASSEMBLY INCORPORATING A DABBING DEVICE - A printhead maintenance assembly having an ink manifold with a printhead, the manifold operatively supplying the printhead with ink. The assembly also includes a capper arrangement having a capper operatively fitted to the manifold over the printhead, the capper defining a capper chamber with a constriction member splitting said chamber into an air inlet channel and a vacuum channel, the constriction member located proximate the printhead to define a blast channel therewith between the inlet channel and the vacuum channel. The assembly also includes a dabbing device to dab the printhead after disengagement of the capper with the printhead. | 2008-10-09 |
