Abstract: A relay electronic device establishes a first near field wireless connection to a primary electronic device, and receives network connection information of the primary electronic device that is sent by the primary electronic device. The relay electronic device establishes a second near field wireless connection to a secondary electronic device, and receives network connection information of the secondary electronic device that is sent by the secondary electronic device. The relay electronic device determines, based on a first message and a second message, whether a policy for projecting media data of the primary electronic device to the secondary electronic device is directly projecting the media data of the primary electronic device to the secondary electronic device or projecting, by the primary electronic device, the media data of the primary electronic device to the secondary electronic device by using the relay electronic device.

Abstract: A method and device for calculating a river surface flow velocity are provided based on a variational principle, which are used to capture and process the images of an objective area, and to obtain the flow velocity field data of the objective area with high precision in a non-contact manner. The method and device include 3 steps: (1) preparation before initial flow measurement; (2) capturing a video of the river by an image acquisition device, converting a motion of a pixel flow field of the fluid in a captured image sequence into solving an energy functional optimization problem, and solving partial differential equations to obtain data of pixel flow field distribution; and (3) obtaining space coordinates of the pixel point in a world coordinate system and calculating the flow velocity according to the data obtained in the step 2 and the transformation relationship determined in the step 1.

Abstract: A method and an apparatus for processing release of connection resources are provided. The method includes: stopping transmitting a service message to a Mobile Switch Center (MSC) in a first preset duration after receiving a reset message transmitted by the MSC, and restoring transmission of the service message to the MSC after the first preset duration, where release of connection resources between a Base Station Controller (BSC) and the MSC is ensured to be completed in the first preset duration. Through the method and the apparatus for processing the release of the connection resources, after the MSC transmits the reset message, it is ensured that the services of other MSCs are not affected and also the connection corresponding to the MSC transmitting the reset message on the BSC is released, so new services are not affected accordingly, thereby improving Quality of Service (QoS) of the services.
