  • Closed compressed gas power and thermal management system
    Patent number: 11149635
    Abstract: System and methods are provided that use a recharge device to resupply a reservoir and tank with fluids used to power a turbine, which in turn powers a generator, wherein one of the resupplied fluids is used to cool a load that is powered by the generator.
    Type: Grant
    Filed: May 22, 2020
    Date of Patent: October 19, 2021
    Assignee: ROLLS-ROYCE NORTH AMERICAN TECHNOLOGIES INC.
    Inventors: Michael Karam, Kaare Erickson, Robert Duge
  • Compressed gas integrated power and thermal management system
    Patent number: 11028773
    Abstract: Systems and methods are provided that use compressed gas to power a turbine, which in turn powers a generator, where an expansion of the compressed gas provides cooling for an electrical load that is powered by the generator.

  • Radiant electromagnetic energy management
    Publication number: 20070051233
    Abstract: A device provides a radiant electromagnetic energy output. During standby operation of the device, the output is provided at one or more frequencies selected to dissipate excess power through atmospheric absorption. Circuitry is included to tune the output of the device to a second frequency different than the first frequency for various directed energy applications that make use of the excess power. The circuitry can be arranged to further utilize frequency agility for power dissipation, to provide different operating modes involving a radiant output, or the like.
