Abstract: A plurality of multicarrier signals is generated. Each of the plurality of multicarrier signals includes a pilot symbol sequence at a same temporal point in each multicarrier signal. Each pilot symbol sequence includes a plurality of pilot symbols with non-zero amplitude. The pilot symbol sequences are orthogonal to each other at the same temporal point. A quantity of the plurality of pilot symbols in each pilot symbol sequence is greater than or equal to a quantity of the plurality of multicarrier signals to be transmitted. The plurality of multicarrier signals are transmitted in an identical frequency band from a plurality of antennas. The plurality of antennas includes two, three, or four antennas.

Abstract: Enhanced media transport systems and structures are provided for printing environments. Enhanced vacuum table structures and associated methods may also be implemented for a variety of printer systems. Enhanced rail systems and associated carriage structures may preferably be used within a variety of printing environments, such as for but not limited to grand scale printers. Water-based binary epoxy ink compositions and associated processes provide adhesion and material compatibility that exceeds that of currently available UV curable products, while providing ultra-low volatile organic carbon (VOCs), and no hazardous air pollutants (HAPs). An integrated system and method for identification of consumables through a central database may also be implemented within different printing systems.

Abstract: A method and apparatus for printing digital ink jet images to be backlit by a light source is provided. Such backlit printing relies upon additional color pigment to be hidden in the white layer to add additional color density to the image as the back light source passes light through the layers. Print heads are divided into a region of multiple single color print head arrays and a region of white and color print region printed over a color print region. Such backlit printing may be used on both first surface printing and second surface printing. When such backlit printing is used, it may not be necessary to divide the print heads exactly in half as one layer may require less print nozzles than the other as the interlacing and or DPIs may vary for the different layers.

Abstract: A multi-color ink jet printing system uses a two-part (Binary) imaging solution, where the precise mixture of the multiple fluid parts (Colorant(s) and Reactant) is controlled with the use of multiple drop size (Grey Scale) ink jet print heads. The precise mixture of colorant(s) and reactant initiates a chemical reaction, which cures the imaging solution into a solid or nearly solid compound that ensures proper drop location.
