  • Human echolocation system
    Patent number: 7957224
    Abstract: A human echolocation system emits toward a target a series of sound pulses beginning at a low frequency and progressing stepwise to a high frequency. Echoes of the pulses enable the user to estimate location, distance and dimensions of the target. Target location and distance are estimated based on a stretched echo delay, while target dimensions are estimated based on a musical pitch corresponding to the echo frequency.
