David S. de Villiers 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).

  • Methods for providing optimal light-CO2 combinations for plant production
    Patent number: 7502655
    Abstract: Method for optimizing plant production in a cost effective manner. System (100) includes a processor (102) in communication with resource controllers (110, 112) for controlling resources (106, 108) such as, for example, lighting and carbon dioxide. Each resource has a cost that varies temporally or with other factors. The processor implements an algorithm that receives a desired plant production rate and other input, such as operating conditions of the system and environment, and determines amounts of each resource to expend consistent with plant production goals and resource costs.
    Type: Grant
    Filed: January 29, 2007
    Date of Patent: March 10, 2009
    Assignee: Cornell Research Foundation, Inc.
    Inventors: Louis D. Albright, Konstantinos Ferentinos, Ido Seginer, David S. de Villiers, Jeffrey W. Ho
