Abstract: The invention relates to the technical field of oil and gas field development, in particular to a staged multi-cluster fracturing sliding sleeve system and method based on smart key label. The system includes at least one multi-cluster sliding correspondingly placed in each fracturing stage, an end sliding sleeve, and a smart key label. The method includes: step S1, performing fracturing stage by stage from a first stage to a last stage, placing the smart key label through a wellhead and pumping the smart key label to the target fracturing stage; step S2, opening the multi-cluster sliding sleeves of the current fracturing stage one by one through the smart key label, and finally blocking the smart key label in the end sliding sleeve when the multi-cluster sliding sleeve and the end sliding sleeve of the current fracturing stage are opened; and step S3, repeating the steps S1 and S2 until the fracturing operations of all the stages are completed.

Abstract: A color filter (CF) substrate includes a CF structure disposed on a base, and multiple pixel regions each including multiple sub-pixel regions. The CF structure includes a nanostructure layer including multiple nanostructures and a light guide structure layer including multiple light guide structures, sequentially provided on the base. Each light guide structure is in a corresponding pixel region, and includes multiple light guide sub-portions. Each light guide sub-portion is in a corresponding sub-pixel region. Each sub-pixel region corresponds to a nanostructure, and each nanostructure is in a corresponding sub-pixel region. Each of the light guide sub-portions in one pixel region is configured such that light incident on the light guide sub-portions exits at different angles and enters into the nanostructure in the sub-pixel region corresponding thereto. Each nanostructure is configured such that light exiting from the sub-pixel region corresponding thereto has a predetermined color.

Abstract: Disclosed are systems and methods for providing ring back tones in a communication network. At first, a ring back tone device for storing and playing the ring back tone customized by a subscriber is established in the communication network. Whether a subscriber is a ring back tone service register subscriber is judged with a certain triggering mode, such as intelligent network triggering, signaling interception triggering, call forwarding triggering or switching device triggering. If it is judged the subscriber is a ring back tone service registered subscriber, a connection between the originating switching device and the terminating switching device and a connection between a switching device and the ring back tone device are established. When the called terminal is idle, the ring back tone device provides a piece of customized ring back tone to the calling subscriber for replacing traditional ring back tone.
