Patents by Inventor Eliot Goldstein

Eliot Goldstein 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).

  • Heat exchanger
    Patent number: 8540012
    Abstract: A heat exchanger and a method for fabricating the heat exchanger are disclosed. The heat exchanger comprises a heat exchanger core that is formed from a plurality of stacked aluminum panels that are joined together via friction stir welding. Each panel in the core is formed from at least two aluminum extrusions that are joined to one another via friction stir welding.
    Type: Grant

    Date of Patent: September 24, 2013
    Assignee: Lockheed Martin Corporation
    Inventors: Nicholas J. Nagurny, Natalie B. Levings, Derek M. Beckner, Michael R. Eller, Patrick D. Grandelli, Joe Van Ryzin, Eliot Goldstein, Randy J. Brown, Leslie D. Kramer, Robert J. Howard
  • Engine and technique for generating an acoustic signal
    Patent number: 7936641
    Abstract: An embodiment of a device for generating an acoustic signal in a fluid includes an engine operable to repeat a thermodynamic process to vibrate a membrane of the engine to generate an acoustic signal having more than one period. The thermodynamic process includes heating mass inside a chamber of an engine to generate pressure inside the chamber; in response to generating the pressure, moving in a first direction a portion of a membrane of the engine; removing mass from inside the chamber to decrease the pressure inside the chamber; and in response to decreasing the pressure inside the chamber, moving the membrane portion in a second direction. In an embodiment, because the engine repeats the thermodynamic process, the engine can generate and sustain an acoustic signal for a significant amount of time.
