  • Publication number: 20090097458
    Abstract: A method and system for agent redirecting the terminal request is provided. Firstly a uniform service address is preset for each service in the terminals. The terminal initiates a service access request. The agent gateway queries the service subscribing information of the user. The agent gateway determines the type of the service requested by the terminal according to the uniform service address and queries the address of the corresponding service server. The agent gateway transmits the service access request to the service server obtained by query. The service server returns the access response of the service to the terminal via the agent gateway. The present invention can choose the suitable service server and agent redirect the service access request to the designated service server in the case that multiple servers exist by presetting the uniform service address in the terminal.

  • Publication number: 20080210965
    Abstract: Light-emitting diode packages with very high light extraction efficiency are disclosed. The packages utilize the intrinsically optically transparent nano particles with high refractive index, by the correct way of homogeneous packing, or adding additional transparent substance in the interspaces among the nano particles furthermore, to form a nano light-extracting layer with high refractivity which contacts optically with the diode surface to extract the light. By this method, because the refractive index difference between the light-extracting layer and the diode crystal turns to be small, the critical internal total reflection angle of the light on the interface increases much, it means large reduction on the internal total reflection of the light. Then the light extraction efficiency of the package can be increased significantly.
