  • Patent number: 11002856
    Abstract: Systems and methods for imaging object velocity are provided. In an embodiment, at least one Time-of-Flight camera is used to capture a signal representative of an object in motion over an exposure time. Illumination and modulation frequency of the captured motion are coded within the exposure time. A change of illumination frequency is mapped to measured pixel intensities of the captured motion within the exposure time, and information about a Doppler shift in the illumination frequency is extracted to obtain a measurement of instantaneous per pixel velocity of the object in motion. The radial velocity information of the object in motion can be simultaneously captured for each pixel captured within the exposure time. In one or more aspects, the illumination frequency can be coded orthogonal to the modulation frequency of the captured motion. The change of illumination frequency can correspond to radial object velocity.

  • Patent number: 11002853
    Abstract: To clear the line-of-sight (LOS) on a window in a lidar system within a vehicle, ultrasonic transducers are physically attached to the interior surface of the window to remove debris. When debris is detected at the window, the ultrasonic transducers are directed to vibrate at an ultrasonic frequency thereby generating an ultrasonic wave which causes the debris to bounce off the window. In some scenarios, the ultrasonic transducers vibrate with a particular phase shift to generate a travelling wave that causes the debris to sweep across the window. Additionally, windshield wipers, spray from a nozzle, and/or a hydrophobic or oleophobic coating may be used in combination with the ultrasonic transducers to remove the debris from the window.

  • Patent number: 10955523
    Abstract: An underwater navigation algorithm (UNA) uses acoustic signals transmitted in the ocean from sources at known positions to compute a position underwater for a vehicle that requires no initial a priori position or any ocean sound speed information or any initial GPS position that would require surfacing. The UNA consists of two parts, (1) the Cold Start Algorithm (CSA) and (2) the CSA with Modeling (CSAM). The underwater vehicle needs to be equipped with only a single hydrophone acoustic receiver and an onboard processor. The CSA requires only measuring the travel time of the end of the arrival coda (EOC) from each of the sources to compute a position. The CSAM is a post CSA procedure to calculate a higher accuracy position using the CSA position.

  • Patent number: 10935645
    Abstract: Methods, systems, and apparatuses are disclosed for ultrasound imaging comprising Time Delay Spectrometry. A frequency swept signal can be transmitted through a medium, such as human tissue. The signal can be a low-voltage signal (e.g., 0 volts to 5 volts peak-to-peak) transmitted for long duration (e.g., 20 milliseconds) at various frequencies. As the signal propagates through the medium it can be reflected and delayed. A delay associated with the signal the can cause a change in the associated frequencies. The signal can be filtered to retain only frequencies in an audio frequency range. The signal can be beamformed and processed to produce an image.
