Abstract: A method for collecting data of a surrounding of a plurality of motor vehicles by a data collection system involves generating a collection job having a first set of information describing which data are to be collected by the plurality of motor vehicles, and a second set of information describing when the data are to be collected, for the plurality of motor vehicles. The collection job is transmitted to the plurality of motor vehicles by a communication device of the data collection system. Preprocessed data is received from each motor vehicle. The surroundings of each motor vehicle were captured by a capturing device of each motor vehicle depending on the transmitted collection job to generate collected data and the collected data were preprocessed by an electronic computing device of each motor vehicle to generate preprocessed data and further processing of the transmitted and preprocessed data by the backend server.

Abstract: A foldable display device includes a first support member, a second support member rotatably connected to the first support member, a primary display screen, and a secondary display screen fixed on the second support member. The first support member includes a flat surface, and a first arc surface and a second arc surface respectively connected to opposite sides of the flat surface.

Abstract: The present invention relates to a CMOS image chip, a camera, thereof, and a debugging method thereof. The CMOS image chip of the present invention disposes light emitting diodes in a light emitting region and uses a projection pattern of the light emitting diodes on a substrate to be inspected to determine a photosensitive effective region of the CMOS image chip on the underlay to prevent the issue that the conventional technology uses an image by camera imaging on a display device as debug basis and a camera imaging image has signal delay to result in a low debugging efficiency, which drastically improves a debugging efficiency of the camera.
