  • Patent number: 11506747
    Abstract: The present disclosure relates to an acoustic position determination system that includes a mobile communication device and at least one base transmitter unit. The mobile communication device is configured to transmit and receive acoustic signals. Due to relative movements between the mobile communication device and the base transmitter unit, frequencies of the received signals shift due to Doppler effect. The mobile communication device is configured to compensate Doppler frequency shifts in the received acoustic signals prior to performing a deconvolution decoding process. The mobile communication device is further configured to compensate Doppler frequency shifts and perform deconvolution decoding process on acoustic signals received from multiple signal transmission paths.

  • Patent number: 11500094
    Abstract: Sensing apparatus includes a radiation source, which emits pulses of optical radiation toward multiple points in a target scene. A receiver receives the optical radiation that is reflected from the target scene and outputs signals that are indicative of respective times of flight of the pulses to and from the points in the target scene. Processing and control circuitry selects a first pulse repetition interval (PRI) and a second PRI, greater than the first PRI, from a permitted range of PRIs, drives the radiation source to emit a first sequence of the pulses at the first PRI and a second sequence of the pulses at a second PRI, and processes the signals output in response to both the first and second sequences of the pulses in order to compute respective depth coordinates of the points in the target scene.

  • Patent number: 11500054
    Abstract: Systems and methods for presenting marine information are provided herein. A system includes an array of a plurality of sonar transducer elements associated with a watercraft and a display. The system causes presentation of a chart of a body of water, including a representation of the watercraft at a current location. The system also operates the array to cause transmission of sonar beams into the underwater environment and receives sonar return data from the array. The system further generates, based on the sonar return data, a two-dimensional live sonar image, determines a facing direction of the array, and causes presentation of the sonar image in the facing direction on the chart and relative to the representation of the watercraft. Accordingly, live sonar imagery is presented on the chart to visually provide a relationship between objects within the live sonar imagery and the real-world position of those objects.

  • Patent number: 11493628
    Abstract: Aerial vehicles including one-dimensional arrays of transmitters and receivers aligned perpendicular to one another are configured for safe operation. The transmitters may be configured to transmit signals at designated times in order to generate synthetic waves having common fronts from selected angles. The receivers are configured to capture data regarding reflections of the synthetic waves from objects, and to interpret the data to determine bearings or angles to such objects. Locations of the objects may be determined based on angles at which the synthetic waves are transmitted and bearings or angles to the objects that reflected the synthetic waves, as well as times at which reflections of the synthetic waves are received. Maps or other representations of objects on a scene may be generated based on such locations.

  • Patent number: 11448755
    Abstract: Technologies for correcting beamformed data are disclosed. A sonar computing device receives, at two or more sets of two-dimensional (2D) subarrays of a multi-element detector array, raw data representing a three-dimensional (3D) volumetric view of a space. A first set of subarrays of the two or more sets of subarrays includes elements of the detector array along a first direction. A second set of subarrays of the two or more sets of subarrays includes elements of the detector array along a second direction. The raw data is subdivided into slices and beamformed. The beamformed data is corrected by, per slice, obtaining first phase data from the first set, obtaining second phase data from the second set, correcting a beam position of each beam in the first and second directions per voxel based on the first and second phase data, and interpolating the corrected beam positions to an output grid.
