Patents by Inventor Greg Whiffen

Greg Whiffen 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: 6151566
    Abstract: A piecewise continuous-time dynamic control method and apparatus for optimizing remediation of groundwater is disclosed. The piece-wise continuous control process is used to generate efficient designs for rededication systems based on differentiable groundwater models. The remediation strategies generated are characterized by piece-wise continuous functions of time which dictate the operation of remediation devices. The piece-wise continuous functions may change discontinuity at the end of each management period, or optionally, a finite number of times during each management period. The duration and number of management periods covering a groundwater cleanup may be selected by the user of the invention to maximize the contamination removal efficiency and reflect the mechanical limitations of the specific rededication devices chosen.
