Abstract: Print jobs are automatically and transparently spooled in a device-independent format, such as an enhanced metafile format. The enhanced metafile format provides a format into which documents are readily converted and which occupies a minimal amount of storage space. Each spooled print job is asynchronously printed relative to a program that requested the print job. Such spooled print jobs are de-spooled in a background processor mode. An operating system provides the resources for converting a print job into enhanced metafile format and spooling the print job in the enhanced metafile format.

Abstract: Disclosed in this invention is an optical filter to enhance the contrast and brightness of images from a color display. The filter comprises suitable dyes and a polymer matrix, applied in a suitable form on the display unit. Such filters have utility in devices based on CRTs, plasmas and the like.

Abstract: This invention provides novel liquid crystalline polymers which, when blended with a suitable dye at a suitable high temperature and extruded, yields polarizer films with superior thermal and hygroscopic stability and polarizing efficiency. The invention further provides a process to prepare such polarizer films.

Abstract: This invention provides laminates useful for display device applications. An illustrative laminate comprises a polarizing film, and a protective layer, bonded by means of an intermediary adhesive layer. A polarizing film useful for such a laminate construction comprises a liquid crystalline polyester and a dichroic dye. The invention further provides a process to prepare such laminates.

Abstract: An operating system provides a point-and-print capability to users of the workstation. The point-and-print capability allows a user to print on any printer available within a distributed system by simply selecting a printer and requesting to print on the printer. The retrieval of configuration information and installation of the printer is performed transparently relative to the user of the workstation. The required printer configuration information is retrieved from a database that is maintained at a network server for the network that includes the target printer. A heuristic technique is employed to obtain complete printer configuration information when such printer configuration is not fully available from the network server.

Abstract: This invention provides all organic high extinction polarizers based on blends of novel liquid crystalline polymers and suitable dichroic dyes. The invention further provides a process to prepare such polarizer films.

Abstract: This invention provides process embodiments for fabricating polymeric channel or rib optical waveguides.An invention optical waveguide has a channel or rib structure which has a polymer thin film smooth-wall lining on its surfaces to minimize optical loss by scattering of propagating wave energy.The smooth-wall channel waveguide polymeric medium is in combination with polymeric cladding thin films to form a laminated matrix. The polymers in the waveguiding medium and the lining and cladding thin films of the laminated matrix preferably have side chains which exhibit second order nonlinear optical susceptibility, and which can be molecularly oriented by an electric field.
