Patents by Inventor Nanda Nathan

Nanda Nathan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8807029
    Abstract: Embodiments of the present invention dispense with the need for lithographic printing plates, instead facilitating direct transfer of ink from a permanent cylinder to a recording medium. Accordingly, instead of being permanently modified to exhibit oleophilic and oleophobic (or hydrophilic) regions, the cylinder is effectively “programmed” with the image prior to each transfer of ink.
    Type: Grant
    Filed: August 16, 2012
    Date of Patent: August 19, 2014
    Inventors: Thomas E. Lewis, Nanda Nathan
  • Patent number: 8798104
    Abstract: In various embodiments, output beams of multiple seed lasers differing in at least one beam characteristic are combined, amplified, and separated according to the beam characteristic(s) for use in, e.g., plateless lithographic printing.
    Type: Grant

  • Patent number: 8114248
    Abstract: A method and system referred to as PALM (Patterning by Adhesive of Large Relief Three-Dimensional Microstructures) with large reliefs exceeding 1 ?m and being as large as 100 ?m. The microstructures can be either deterministic (such as microprisms), or random (such as diffusers), the first obtained by copying an original supermaster, and latter obtained by copying a laser speckle pattern. The master process entails copying a supermaster into the form of the microstructure constituting a pattern on the patterning cylinder (called a drum), to be then continuously multiplied in the PALM system, in a continuous roll-to-roll web process. The latter method, together with the related system, is the subject of this invention. The rolls continuously repeat the master pattern, copying by adhesive with large viscosity on acrylic (hybrid) as well as by a monolithic process. The monolithic process can be accomplished using temperature and pressure, or by UV-cured polymerization.
