The system may instruct the one or more vehicles that are to receive the one or more minimum services to travel to the one or more service centers to be serviced.

Abstract: A method and a system for detecting backscattered electrons in a multi-beam electron column.

Abstract: The present invention relates to a sensor for electron detection emitted from an object to be used with a charged particle beam column being operated at a certain column and wafer voltage. The sensor is configured and operable to at least reduce interaction of negative ions with the active area of the sensor while minimizing electrons energy loss.

Abstract: In one embodiment, a method includes a computing system receiving information from an autonomous vehicle (AV). Based on the received information, the system may identify a target objective, with an associated target destination, for the AV and determine that the AV is able to transport passengers while furthering the target objective. The system may receive multiple ride requests from ride requestors, respectively. Each of the ride requests is associated with an origination location and a destination location. The system may match the AV with one of the ride requests based on a location of the AV, the target destination of the target objective, and the origination location and destination location associated with the ride request. The system may instruct the AV to perform a transportation task from the origination location to the destination location associated with the ride request, and drive to the target destination after completing the transportation task.

Abstract: In particular embodiments, a computing system may generate a prediction of requests for autonomous vehicles in a fleet of collectively managed autonomous vehicles based on a current condition and a future event, the prediction including a predicted request level and a predicted duration of the request level.

In particular embodiments, the prediction of requests may be generated using machine learning.
