  • Publication number: 20070200657
    Abstract: A thermal fuse varistor assembly with an insulating glass passivation layer has a varistor, electrodes, an insulating glass passivation layer, a lead assembly, a fuse, an insulating glass passivation glue and a coating. The varistor has a top surface and a bottom surface. The electrodes are respectively applied to the varistor. The insulating glass passivation layer is applied to the whole electrode on the top surface of the varistor The lead assembly is connected to the electrodes and has a first lead, a second lead and a third lead. The first lead is connected to the electrode on the bottom surface of the varistor. The second lead is connected to the electrode on the top surface of the varistor. The third lead is located on the insulating glass passivation layer. The fuse is connected between the electrode on the top surface of the varistor and the third lead.

  • Publication number: 20050235056
    Abstract: A location awareness system for a wireless local area network (WLAN). The location awareness system of the present invention allows the infrastructure owner to control the content and method of location related information. The location information translation is performed by the local area server, thus private information is protected inside the WLAN, hidden from to the public presence server. The location awareness system comprises an area agent, a local area server, and a presence server. The area agent obtains location information by providing the area tag to the local area server, and only submits the authorized location information (location awareness information) to the presence server either directly or by the local area server. The present invention further comprises a relay as a cache between the area agent and the local area server.

  • Publication number: 20050190772
    Abstract: A triggering method for IP multimedia service control. The triggering method comprises monitoring a session state or user state according to a set of specific filter criteria, recording a corresponding SIP request message, and triggering an application server designated by the criteria if a trigger point thereof matches the session state or user state. Furthermore, the SIP-server performs additional action effectively manage the session or services according to the Action defined in the user profile. The scheme is suited to application services triggered according to session state or user state, and is compatible with the iFC scheme defined in 3GPP. The present invention improves the efficiency of communication and enhances the flexibility of the SIP server.
