  • Patent number: 10586458
    Abstract: A hybrid trip planning system can receive transport requests from requesting users, and determine a pick-up location from each transport request. The pick-up location can be within or external to an autonomy grid on which a plurality of autonomous vehicles (AVs) can operate in an autonomous mode. The system can further determine a drop-off location from the transport request, the drop-off location also being within or external to the autonomy grid. The system can select and route an AV to a most optimal entry and/or exit point of the autonomy grid based on the transport request, where the selected AV is to switch between a manual and an autonomous mode.

  • Publication number: 20200068161
    Abstract: Disclosed is a method for converting an HDR image into an SDR image. The method includes the following operations: acquiring, by a television terminal, input HDR image data, and processing, by the television terminal, the acquired HDR image data through a first normalization; linearizing, by the television terminal, the HDR image data processed through the first normalization; processing, by the television terminal, the linearized HDR image data through a second normalization; and converting, by the television terminal, the HDR image data processed through the second normalization into SDR image data with a supported format. The present disclosure further provides a television terminal and a computer readable storage medium. The present disclosure effectively avoids the technical problem of a poor image display effect caused by that the non-HDR receivers cannot show the HDR effect. The present disclosure enables non-HDR receivers to show the HDR effect and improves the image display effect.

  • Patent number: 10438493
    Abstract: A hybrid trip planning system can receive transport requests from requesting users, determine pick-up and/or drop off locations from the transport request, and select available autonomous vehicles (AV) to service the transport requests. For each transport request, the planning system can identify a plurality of entry points from the pick-up location to an autonomy grid on which the AVs operate, and a plurality of exit points from the autonomy grid to the drop-off location. The planning system may determine optimal entry and/or exit points and transmit transport data to the selected AV. The transport data can provide optimal routing for a human safety driver to drive the selected AV in manual segments that are off grid, and switch the AV into an autonomous driving mode within the autonomy grid.
