    摘要： The present disclosure relates to telecommunication, and in particular, to a base station Radio Frequency (RF) duplexer, an RF module, and an RF system. A base station RF apparatus provided herein includes: an enclosure, an intermediate RF processing unit, and a duplexer. The enclosure is located on the duplexer; the intermediate RF processing unit is located inside a cavity enclosed by the enclosure and the duplexer, or on the duplexer; a duplexer cavity and a heat dissipation part exist on the surface of the duplexer; the opening of the duplexer cavity is opposite to or against the enclosure; the heat dissipation part is designed to dissipate heat of the intermediate RF processing unit; and the duplexer is integrally molded. The foregoing technical solution requires no external fasteners, reduces the time of production and assembly. In addition, waterproof design and shielding design are not required, and thus improves the reliability.

    摘要： The disclosure provides a method and a system for network handover. The method includes: during a process that equipment hands over from a current network to another network, a driver receiving a network-disconnected message, and judging whether the network-disconnected message is sent from a Connection Manager (CM); if the network-disconnected message is sent from the CM, the driver reporting, to an operating system, a first signalling which identifies that the current network is disconnected; and if the network-disconnected message is not sent from the CM, the driver reporting, to the operating system, a second signalling which identifies that the current network is connected. By the adoption of the method and the system, power consumption of the equipment can be reduced.

    摘要： There are provided methods and systems for precisely controlling the surfactant concentration and character of ferroelectric nanoparticles in a ferroelectric liquid crystal dispersion. In an aspect, the invention provides an efficient FTIR technique to characterize the status and measure the distribution of the surfactant in ferroelectric particle dispersion. This allows for establishing a reproducible fabrication process for ferroelectric nanoparticle liquid crystal dispersions. The methods also maintain the nanoparticles ferroelectricity, which is provided by the addition of surfactant during a comminution process. The invention therefore optimizes both the milling time (to achieve small particle size and narrow size distribution) and surfactant concentration (to maintain the ferroelectricity during milling).
