Abstract: An improved structure of a planar heat pipe, having a top lid and a bottom lid. The bottom lid can be engaged with the top lid. A wick structure and a working fluid are installed in the heat pipe. The top lid has a top panel, which has a central flat area and a plurality of independent heat dissipating fins spirally arranged around the flat area. Each of the heat dissipating fins has a cone shape, and the height of the heat dissipating fins gradually increases from the center to the periphery of the top lid. A spiral heat circulating path is thus formed on the top lid. Thereby, when the cooling fan generates cooling air flow downwardly, an air impingement is formed upon the flat region of the top lid. The heat accumulated in the central flat region is then dissipated by the heat dissipating fins with an enhanced efficiency.

Abstract: In accordance with the teachings of the present invention, a method and apparatus of performing traffic mode broadcast multicast is implemented by leveraging the existing traffic channel structure and infrastructure. In one embodiment, a method and apparatus is presented for providing broadcast multicast service using the traffic channel, specifically the supplemental channel.

Abstract: A method for communicating additional network information using a synchronization identifier is presented. A synchronization identifier is defined. The synchronization identifier is used for the purpose of synchronizing communication between a Mobile Station (MS) and a network. In addition, the synchronization identifier is used to define additional functionality in the wireless network. As such, the synchronization identifier may be used to communicate information about wireless services and/or wireless components between the MS and the network.

Abstract: A tabular heat pipe structure with support bodies has a housing, working fluid received in the housing and support bodies. The top and bottom faces of the support bodies are zigzag faces having a plurality of contact points. The support bodies use these contact points to adhere to the housing by means of welding. The tabular heat pipe structure is uniform and intact, has a high rigidity, will not cave in and deform due to back pressure in the heat pipe, and will not let the housing separate from the support bodies because of expansion at high temperatures. Therefore, the tabular heat pipe structure has the advantages like a better heat-conducting characteristic, a smaller contact heat resistance, a simple processing procedure, a quick manufacturing speed, a lower cost, and a simple and stable operation of flat adhesion.
