    Abstract: Certain embodiments are described that provide a method for obtaining a registration point for a map. A drone is equipped with a GPS receiver and is flown to, and lands on, a physical location corresponding to a designated point on the map. While the drone is at the physical location, it receives GPS data using the GPS receiver for a period of time sufficient to allow convergence of the GPS data to obtain a GPS coordinate. The GPS coordinate is then associated with the designated point on the map, to generate the registration point for the map.

    Abstract: Methods, systems, and apparatuses to predict a future position of a vehicle travelling along a path; determine, based on the predicted future position of the vehicle, a subset of map data from a set of map data stored in a data repository housed in the vehicle; and dynamically pre-load the determined subset of map data from the data repository to a cache memory storage housed in the vehicle for expedited access of the determined subset of map data by at least one computation unit housed in the vehicle.

    Abstract: Certain embodiments use image-based technologies (e.g., digital cameras, light detection and ranging (LIDAR) systems, etc.) to monitor a driver-side floor space in a vehicle cabin and warn the driver when a foreign object is blocking or may potentially block a vehicle control (e.g., brake pedal). A foreign object can include a bottle, can, electronic device, keys, books, or the like. In some cases, foreign objects are detected by comparing a current image of the driver-side floor space with a reference image that is known to be free of foreign objects. The difference image can be used to identify any foreign objects in the driver-side floor space, and a corrective action can be taken to address the potential danger. Some corrective actions may include an audio and/or video alert to the driver, or in some cases, the vehicle may autonomously guide the vehicle to a safe location and stop.

    Abstract: An attention monitoring system is disclosed. The system may comprise a sensor configured to monitor a steering wheel of a vehicle, and a processor. The processor may be configured to determine if at least one hand is placed on the steering wheel based on the monitoring, and alert the vehicle's driver in response to determining that no hand is placed on the steering wheel. An autonomous driving function of the vehicle may be enabled.

    Abstract: A method for improved position estimation. The method includes: receiving first position information from a first GNSS receiver of a vehicle dashboard camera, receiving second position information from a second GNSS receiver of a mobile device carried by a user and proximate the first GNSS receiver, and, when it is determined that the vehicle dashboard camera and the mobile device share the same inertial reference frame and are within the first distance and that the accuracy of either the first position information or the second position information falls beneath the threshold and that the predicted course of either the vehicle dashboard camera and the mobile device is calculated to pass through the region of poor satellite reception, time synchronizing the second position information with the first position information, and combining the first position information with the second position information to determine third position information.
