Abstract: During a measurement technique, an electronic device may receive first sensor information associated with a first field of view and a first timestamp, and second sensor information associated with a second field of view and a second timestamp. For example, the electronic device may perform a first measurement using a first sensor and performing a second, different type of measurement using a second sensor. Therefore, the first sensor information and the second sensor information may be associated with different types of sensors. Moreover, the first timestamp and the second timestamp may be concurrent or in close temporal proximity, and the first field of view and the second field of view may at least substantially overlap. Then, the electronic device may store the first sensor information and the second sensor information in memory. In some embodiments, the electronic device stores the first timestamp and the second timestamp in the memory.

Abstract: A circuit board in an electronic device includes a first set of transmit antennas and a first set of receive antennas arranged along an azimuth direction, and a second set of transmit antennas and a second set of receive antennas arranged along a direction that includes components in the azimuth direction and an elevation direction. Moreover, separations between adjacent transmit antennas in the first or second set of transmit antennas along the azimuth direction may be greater than one half of the fundamental wavelength. Furthermore, separations between adjacent receive antennas in the first or second set of receive antennas along the azimuth direction may equal one half of the fundamental wavelength. Additionally, adjacent antennas in the second set of transmit antennas and the second set of receive antennas may be partially offset from each other and partially overlap with each other along the elevation direction.

Abstract: During a location technique, a sensor module in a vehicle, which has non-retractable wheels in contact with a driving surface, determines a location of the vehicle. In particular, the sensor module is positioned on or in a direction of a side-facing surface of the vehicle. Moreover, during operation, the sensor module may transmit radar signals approximately perpendicular to a direction of motion of the vehicle. Then, the sensor module may receive reflected radar signals. Furthermore, the sensor module may analyze a time sequence of the reflected radar signals. Next, the sensor module may determine the location of the vehicle based at least in part on the analyzed time sequence of reflected radar signals.

Abstract: During an annotation technique, an electronic device may receive an optical image associated with an object and other sensor information associated with the object, where the optical image and the other sensor information have associated timestamps that are concurrent or in close temporal proximity. Then, the electronic device may identify the object based at least in part on the optical image and/or the other sensor information. Moreover, the electronic device may extract a signature associated with the object from the other sensor information. The signature may include: a range to the object, a first angle to the object along a first axis, Doppler information associated with the object and/or a second angle to the object along a second axis. Next, the electronic device may store annotation information associated with the identified object and the extracted signature in a data structure in memory.
