  • Active control deflection neutralizer
    Patent number: 11312398
    Abstract: Neutralizing deflection in a transportation system comprising connecting a number of support structures to ground. A tube is coupled to the support structures via a number of actuators, wherein the tube defines an interior enclosure through which a vehicle can travel. Utilizing a number of sensors, directional displacement of the support structures can be sensed, and the actuators are controller to counter the sensed displacement of the support structures by producing a directionally-opposite displacement of the tube relative to the support structures.
    Type: Grant
    Filed: January 30, 2019
    Date of Patent: April 26, 2022
    Assignee: The Boeing Company
    Inventors: Robert Erik Grip, Steven Fulton Griffin

  • Phase tailoring for resonant flow devices
    Patent number: 10662987
    Abstract: A device including a resonant array of a plurality of synthetic jet generators where neighboring jet generators are coupled, resulting in the potential for constructive and destructive interference between jets of the plurality of synthetic jet generators depending on the relative phase of a corresponding plurality of drive signals to plurality of synthetic jet generators. The device also includes a controller configured to control the relative phase of the corresponding plurality of drive signals to effect a change in a first jet emitted by a first synthetic jet generator of the plurality of synthetic jets by changing a given phase of a second jet emitted by a second synthetic jet generator of the plurality of synthetic jet generators.
