Patents by Inventor Richard P. Baldwin

Richard P. Baldwin 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: 10191009
    Abstract: Methods and sensing instruments are provided which perform automated electrochemical sensing and determination of metals in a liquid sample, such as drinking water or waste water. With use of microelectrode arrays, concentrations of metal are determined through a double potential step variation on anodic stripping coulometry, and the ability to generate these results provides for compact sensor networks that can be remotely deployed for determination of metals in samples, for real-time, decentralized sample monitoring.
    Type: Grant
    Filed: March 4, 2016
    Date of Patent: January 29, 2019
    Assignee: UNIVERSITY OF LOUISVILLE RESEARCH FOUNDATION, INC.
    Inventors: Mohamed M. Marei, Richard P. Baldwin, Thomas J. Roussel, Jr., Robert S. Keynton
  • Patent number: 10058818
    Abstract: Present embodiments provide an energy-efficient separator having at least two chambers fluidically isolated by a gas permeable membrane for the removal of dissolved gases from a sample which, in some aspects, enables cost-effective monitoring of liquid samples to be performed remotely and automatically, and in other aspects is suited for various other applications where removal and/or regulation of gases in a sample are desirable.

  • Patent number: 7988839
    Abstract: An embodiment of the invention is directed to a capillary electrophoresis apparatus comprising a plurality of separation micro-channels. A sample loading channel communicates with each of the plurality of separation channels. A driver circuit comprising a plurality of electrodes is configured to induce an electric field across each of the plurality of separation channels sufficient to cause analytes in the samples to migrate along each of the channels. The system further comprises a plurality of detectors configured to detect the analytes.
