  • Patent number: 12159451
    Abstract: Aspects of the disclosure provide for automatically generating labels for sensor data. For instance first sensor data for a first vehicle is identified. The first sensor data is defined in both a global coordinate system and a local coordinate system for the first vehicle. A second vehicle is identified based on a second location of the second vehicle within a threshold distance of the first vehicle within the first timeframe. The second vehicle is associated with second sensor data that is further associated with a label identifying a location of an object, and the location of the object is defined in a local coordinate system of the second vehicle. A conversion from the local coordinate system of the second vehicle to the local coordinate system of the first vehicle may be determined and used to transfer the label from the second sensor data to the first sensor data.

  • Patent number: 12144586
    Abstract: Methods and apparatuses are disclosed for capturing and analyzing images of tissue, such as human skin, using variable polarization. Exemplary devices are described having a detection polarizer via which an area of tissue is imaged and one or more light sources whose emitted light is polarized with one or more source polarizers. In a first such device, one or more of the detection polarizer and a source polarizer is rotatable so as to allow the angle between their polarizations to be varied. An area of tissue can be imaged as the angle is varied. Another device has multiple fixed source polarizers of different polarization orientations, each source polarizer polarizing the light emitted by a corresponding group of light sources which can be selectively activated, thereby enabling the device to illuminate an area of tissue with polarized light of different orientations relative to the orientation of the detection polarizer.
