Patents by Inventor Ravishankar Melkote

Ravishankar Melkote 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).

  • Publication number: 20200240883
    Abstract: This disclosure provides a biological sample processing system and methods for processing biological samples. The processing may include one or both of removing wax from wax-embedded biological samples and applying a reagent to biological samples. Aspects of the dewaxing technique and the technique for applying the reagent may be combined to achieve energy efficiencies. Additional efficiency may be achieved by recirculating heated reagent. A hybrid power system may use a source of stored power to supplement external power at times of peak demand. Uniform distribution of liquids across a surface of the biological samples may be achieved by self-leveling using an inclinometer.

  • Patent number: 9551635
    Abstract: In accordance with an embodiment of a system for handling and processing chemical and/or biological samples, a MicroChamber comprises a substrate, a reservoir formed on the substrate for receiving a chemical and/or biological sample, and an encoder such as a barcode or other suitable device. The encoder encodes information describing at least one characteristic of the substrate and/or reservoir.

  • Patent number: 8765476
    Abstract: Automated sample processing systems may include onboard efficient high-speed mixing of at least two components with an automatic vertical force fluidic turbulent component mixer of which a mixed component may be aspirated and high-speed dispensed in a mixing vial. Other aspects may include single sweep applying a multi-treatment cleaning cycle to at least one slide. A multi-treatment cleaning cycle may include a washing treatment and a drying treatment. In yet other aspects the present invention may include an automated recovery sample processing system with the capability of detecting at least one immediate condition of a fortuitously terminated automatic sample processing run and perhaps even an automatic terminated sample processing run reconstruction calculator.
