Abstract: This disclosure relates to a system and method for determining vehicle operator preparedness for vehicles that support both autonomous operation and manual operation. The system includes sensors configured to generate output signals conveying information related to vehicles and their operation. During autonomous vehicle operation, the system gauges the level of responsiveness of an individual vehicle operator through challenges and corresponding responses. Based on the level of responsiveness, a preparedness metric is determined for each vehicle operator individually.

Abstract: This disclosure relates to a distributed data center that includes resources carried by a fleet of vehicles. The system includes sensors configured to generate output signals conveying information related to the vehicles and/or the surroundings of vehicles. The system includes a remote computing server configured to maintain map data and distribute it to the fleet, including local map data to individual vehicles pertaining to their surroundings. Individual vehicles may compare the local map data with the information related to their individual surroundings. Based on such comparisons, individual vehicles may detect discrepancies between the local map data and the information related to their individual surroundings. The remote computing server may modify and/or update the map data based on the detected discrepancies.

Abstract: A swing training includes a bat body having a handle, a barrel and a tapered section joining the handle. The bat body is adapted for hitting a pitched ball. A locking grip is adjustably fixed to the handle and has a bottom end knob and a top end knob. A sliding grip is mounted on the handle and movable between the locking grip and the barrel. The sliding grip has a bottom end knob for stopping the movement of the sliding grip in the direction of the locking grip.
