  • Publication number: 20240237965
    Abstract: A method for determining mechanical properties of tissue in an individual includes attaching a stretchable and/or flexible ultrasound imaging device to the individual. The imaging device includes at least a one-dimensional array of transducer elements that transmit ultrasound waves into the individual. A first series of ultrasound waves are received from the tissue in the individual before applying a strain to the tissue by compression and a second series of ultrasound waves are received from the tissue after applying the compression to the tissue. Data from the first and second series of ultrasound waves are compared to obtain displacement data of the tissue from which strain data representing strain applied to the tissue is obtainable. A 2D image representing a 2D modulus distribution within the tissue is generated using the displacement data. One or more mechanical properties of the tissue is identified based on the 2D modulus distribution.

  • Patent number: 11977165
    Abstract: The technology relates to handling of self-reflections of sensor signals off of a portion of a vehicle that is operating in an autonomous driving mode. Vehicle pose information and sensor pose information are determined at a given point in time while operating in the autonomous driving mode. Return signals from one or more scans of the environment are received from onboard sensors such as lidar sensors. The system evaluates, based on the vehicle and sensor pose information, whether a segment between a given one of the one or more sensors and a received point from a selected one of the return signals crosses any surface of a 3D model of the vehicle. The received point is identified as a self-return point. In response to identifying the received point as a self-return point, the vehicle is able to perform a driving operation in the autonomous driving mode.

  • Publication number: 20230350064
    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for using a surfel map to predict reflections in an environment. One of the methods includes receiving a surfel map comprising a plurality of surfels, wherein each surfel corresponds to a respective different location in an environment. Sensor data for one or more locations in the environment is obtained. The sensor data has been captured by one or more sensors of a vehicle. A range map that represents a projection of the surfel map is generated. Range data in the sensor data is compared to the range map to identify one or more locations in the range map that do not match the range data in the sensor data. The one or more locations in the range map that do not match the range data in the sensor data is classified as reflections.
