  • Systems, methods, and apparatus for debris removal
    Patent number: 10124772
    Abstract: In one example, a method of debris removal includes pressurizing a chamber to displace an elastic top surface of the chamber upward, and modulating the pressure of the mass of air within the chamber to cause the elastic top surface to oscillate in response. When the elastic top surface has been installed on the top surface of a vehicle (e.g., a semi-trailer), such oscillation may be used to impart movement to debris that has accumulated on or over the elastic top surface and remove such debris from the vehicle.
