Abstract: Aspects of the disclosed technology encompass solutions for automatically requesting a backup vehicle for passengers of an autonomous vehicle provisioned ride-hailing service. In some aspects, a process of the disclosed technology includes steps for collecting diagnostic data relating to at least one AV operation, and analyzing the diagnostic data to determine if the AV needs maintenance. Moreover, in response to a determination that the AV needs maintenance, the process can include steps for automatically requesting a backup service for a passenger of the AV. Systems and machine-readable media are also provided.

Abstract: A device (1) for projecting images (2) onto a projection surface (3), having an electro-optical arrangement (29) for generating and emitting light on the basis of image data, and having an optical system (9) for directing the light onto the projection surface (3), which optical system (9) has a movable redirecting mechanism (8?) for the light, which redirecting mechanism (8?) includes a redirecting part (8a) for the image projection and a separate lighttransmitting part (8b) for selective ambience light projection.
