Abstract: This application discloses a patch reuse method, applied to a system that includes a plurality of devices and a patch server, where the patch server is configured to provide patches for the plurality of devices, the plurality of devices are located in a same local area network, and the plurality of devices include at least a first electronic device and a second electronic device. The method includes: The first electronic device sends a first patch query request including reused patch matching information to the patch server, where the reused patch matching information includes first patch matching information of the first electronic device and second patch matching information of the second electronic device; and the patch server sends, based on the reused patch matching information, a reused patch package including a patch file that is required by each device to the first electronic device.

Abstract: Embodiments of this application provide a patch package installation method and an apparatus, and relate to the field of terminals. Embodiments of this application are applied to a system including a first electronic device, a second electronic device, and a third electronic device. The method includes: The first electronic device displays prompt information in a first interface, where the prompt information is used to prompt that patch packages for the second electronic device and the third electronic device are detected; the first electronic device receives a first operation of a user, where the first operation is used to install the patch packages for the second electronic device and the third electronic device; the second electronic device installs a patch package corresponding to the second electronic device; and the third electronic device installs a patch package corresponding to the third electronic device.

Abstract: A data line convenient for storage includes a data line body (1); a plurality of magnetic rings (2) sleeve on the data line body (1); and a plurality of limit tube (3). Each limit tube (3) is arranged between each two adjacent magnetic rings (2). Two opposite ends of each limit tube (3) respectively abuts against the two adjacent magnetic rings (2). When the data line is coiled and stacked into a multiple-layer structure, the magnetic rings (2) located at two adjacent layers attract each other. The magnetic rings (2) at two adjacent layers can attract each other to fix the adjacent layers tightly for storage. The data line is simple in structure, each to use and properly designed to improve user experience.

Abstract: A method for determining optimal weight vector of credit rating based on the maximum default identification ability measured by approaching ideal points is disclosed. The minimum algebraic sum of the Euclidean distances from credit scores of a non-default enterprise to a positive ideal point and the minimum algebraic sum of the Euclidean distances from credit scores of a default enterprise to a negative ideal point are taken as the first objective function, and the lowest dispersion degree of the “distances from scores of a non-default enterprise to a positive ideal point” and the lowest dispersion degree of the “distances from scores of a default enterprise to a negative ideal point” are taken as the second objective function to construct multi-objective programming functions and derive a group of optimal weights of a credit rating equation.

Abstract: The present invention discloses a method for automatically switching a handheld mode and a wireless handheld device. The present invention relates to the field of communications technologies. The method for automatically switching a handheld mode includes: updating, when it is detected that a duration during which handheld positions of a wireless handheld device do not match a preset first handheld mode of the wireless handheld device exceeds a first preset duration, a first user interface matching the first handheld mode to a second user interface matching a second handheld mode, where a layout of controls on the second user interface is a flip horizontal of a layout of controls on the first user interface.
