  • Patent number: 11573858
    Abstract: The present disclosure relates to systems and methods for operation retry. The system may determine whether a retry is allowed for a target operation based on a retry strategy included in a retry proxy component. In response to determining that the retry is allowed for the target operation, the system may execute the target operation. The system may detect whether there is an exception associated with the execution of the target operation. In response to determining that there is the exception associated with the execution of the target operation, the system may determine whether a retry is needed for the target operation based on the retry strategy. In response to determining that the retry is unneeded for the target operation, the system may stop the target operation.

  • Publication number: 20200158522
    Abstract: A method for determining a new route in a map may include obtaining a plurality of original motion sequences. Each of the plurality of original motion sequences may include a departure location and a destination. The method may also include obtaining current route map information corresponding to the plurality of original motion sequences. The method may also include determining, from the plurality of original motion sequences, one or more candidate motion sequences, which have a same departure location and a same destination but being different from the current route map information. The method may also include determining a new route between the same departure location and the same destination based on the one or more candidate motion sequences.

  • Publication number: 20200152183
    Abstract: The present disclosure is related to systems and methods for processing a conversation message. The method includes receiving the conversation message from the client terminal via the data exchange port. The method also includes determining whether the conversation message is associated with at least one pre-set topic category. The method also includes determining a topic category associated with the conversation message based on a prior conversation message in response to a determination that the conversation message is not associated with at least one pre-set topic category. The method further includes determining a semantics associated with the conversation message based on the topic category and the conversation message. The method still further includes generating a response to the conversation message based on the determined semantics to be transmitted to the service system implemented on the client terminal via the data exchange port.

  • Patent number: 9763630
    Abstract: A stereoscopic imaging system and method is disclosed. In one aspect the system includes an X-ray source that emits a plurality of X-ray fanbeams. The system includes columns of detectors. Each column of detectors is arranged at a preset angle with respect to the X-ray source. The detectors detect a strength of an X-ray fanbeam penetrating an object under inspection. The detectors form transmission images when the object intersects, or moves along a direction intersecting with, the X-ray fanbeams. The system includes a reconstruction apparatus that uses any two of the formed transmission images as a binocular image. The reconstruction apparatus calculates depth information of the object on the transmission images. The reconstruction apparatus superposes and fuses the calculated depth information to obtain 3D information. The reconstruction apparatus performs 3D reconstruction so that the detected object can be presented in a stereoscopic manner from different view angles.
