Abstract: The present invention discloses a multimedia conference system and method that enables peer-to-peer communication between private network and the Internet. The multimedia conference system and method that enables direct peer-to-peer communication between private network and the Internet includes: a plurality of user agents (to receive call requests) constituting a local network; a calling terminal positioned outside the local network and connected to the local network via Internet; a network address translation (NAT) positioned on the gate of the local network as barrier between the calling terminal and the user agent, and a SIP Proxy Server positioned between the calling terminal and private network and logically installed in parallel with said NAT to receive session initiation protocol messages transmitted from the calling terminal, connect, and transmit IP addresses, so as to send the message to specific User Agent(s).

Abstract: A scanning system for scanning a document placed on a document platen and for projecting an image onto a photosensitive image medium to form a latent image of the document thereon including a housing, a photosensitive scanner, and a scanning window is provided. The photosensitive scanner is adapted to move beneath the platen in a scan operation for projecting the image onto the photosensitive image medium to form the latent image. The scanning window is mounted on a ceiling of the housing and a fringe of the scanning window bordered with a frame, wherein a top surface of the scanning window is substantially equal to or higher than that of the one side of the frame in height. Furthermore, another scanning system for scanning two pages of a book and projecting an image onto a photosensitive image medium to form a latent image of the document thereon is provided.
