  • Patent number: 7627672
    Abstract: A network packet storage method and network packet transmitting apparatus using the same is provided. A packet content and a path control information are obtained from a received packet, and a packet storage address of the packet content is determined according to a predetermined storage rule. The packet content is stored in a data block and packet storage addresses and path control information of packets output via the same output port are stored in a control block. The data block is output when its size reaches a predetermined data block size such that a dynamic random access memory receives the data block by using burst mode. Further, the control block is output when its size reaches a predetermined control block size.

  • Publication number: 20090065174
    Abstract: A heat sink for an electrical device has a frame and at least one fin. The frame has an inner chamber. The fin is mounted in the inner chamber of the frame to separate the inner chamber of the frame into at least two channels. Therefore, heat generated from any electrical element connected to or mounted on the heat sink will transfer evenly to the heat sink. The heat sink not only dissipates heat evenly, but also provides multiple channels to dissipate heat by convection. Because the heat sink only has one frame, assembly of an electrical device is easy and quick.
