Abstract: A portable computer having a body and display assembly pivotally movable with respect to the body via a hinge mechanism, the display assembly including a hinge frame coupled to the hinge mechanism, the hinge frame including a side vertical wall, a lower wall and an upper wall, and the lower wall and the upper wall being substantially perpendicular to the side vertical wall and spaced from each other; and a display module clamped with the lower wall and the upper wall.

Abstract: There is disclosed a separate structure of a datapath layer and a physical layer within an access network loaded with a V 5.2 protocol in a wireless communication system and communication method between two boards respectively having the datapath layer and the physical layer, which separately forms the protocol board with the datapath layer and the physical layer board section including the multiple physical layer boards with the multiple physical layers and connects the separate two entities using the routing section to allow a protocol to be transmitted and received between the two entities, thereby facilitating the designing of the V5.2 protocol board, the extension of the system and the execution of dualization function of the V5.2 LAYER 3.
