  • Velocity detection in autonomous devices
    Patent number: 11313966
    Abstract: An unmanned aerial vehicle comprising a velocity sensing system is provided. The velocity sensing system comprises a transmitter configured to transmit a first acoustic signal having at least a first frequency and a receiver, configured to detect a second acoustic signal comprising the first acoustic signal after it has been reflected from a reflective surface. The velocity sensing system is configured to determine from the second acoustic signal a second frequency, said second frequency comprising the first frequency after having undergone a Doppler shift; and to use the first and second frequencies to determine a velocity at which the unmanned aerial vehicle is travelling relative to the reflective surface.
