Abstract: A plurality of variable data of personal attribute information associated with at least one vehicle insurance user is received at a prediction server. Based on a service scenario requirement, a pre-constructed prediction algorithm is selected. The plurality of variable data is processed by one or more processors using the pre-constructed prediction algorithm. At least one prediction result is generated as the prediction server.

Abstract: A data transmission method and a data transmission device are provided. The method includes: establishing, by a transmitting end, N different first paths between the transmitting end and a receiving end in an established network; splitting, by the transmitting end, a fixed-length data frame into N first fragments; transmitting, by the transmitting end, the first fragments to the receiving end through the corresponding first paths respectively; splitting, by the transmitting end, the data frame into N-M second fragments in a case that a failure occurs in M of the first paths during transmission of the data frame; establishing, by the transmitting end, N-M different second paths between the transmitting end and the receiving end; transmitting, by the transmitting end, the second fragments to the receiving end through the corresponding second paths respectively.

Abstract: A power supply system for an electric vehicle includes a battery module, a first DC/DC converter, a second DC/DC converter, a first switch, a second switch and a third switch. The battery module has a negative electrode, a first positive electrode and a second positive electrode. The first DC/DC converter has an input terminal connected with the second positive electrode. The second DC/DC converter has an input terminal connected with the second positive electrode. The first switch is connected between the second positive electrode and the first DC/DC converter. The second switch is connected between the second positive electrode and the second DC/DC converter. The third switch is connected between the first positive electrode and an output terminal of the second DC/DC converter.

Abstract: A wireless network access method and apparatus are provided. The method includes obtaining identification information and status information of one or more network access points, determining a target access point according to the status information, submitting the identification information of the target access point to a network access server via a mobile communications network, receiving access account information for the target access point from the network access server, and transmitting a wireless network access request including the received access account information, to the target access point.

Abstract: According to an example, a managing server may establish a relation that associates a downlink interface of a gateway device with information of configuration content, receive a request for configuration content from a network device, identify a downlink interface of a gateway device that is directly connected with the network device, and send configuration content corresponding to the downlink interface of the gateway device to the network device based on the relation that associates the downlink interface of the gateway device with the configuration content so as to implement configurations of the network device.

Abstract: In an anchor rod (1) for a synthetic resin adhesive anchor having a shaft (2) with a plurality of area segments (4) arranged in axial succession, the surface of which is low-friction with respect to synthetic resin mortar (6), areas (4) are formed. Viewed in a circumferential direction, the areas are arranged side by side such that a desired splitting zone (9) is created in the transition region of two adjacent areas (4) of this type.
