Title: Location-based access control for wireless local area networks
Inventor: MANI MAHALINGAM
IPC: H04W4/021
Filed: 2003-05-15
Abstract: A wireless local area network (LAN), and a method of operating the same, prevents unauthorizedusers from accessing the wireless LAN. A signal strength of a station attempting to access the wirelessLAN is measured. If the signal strength is less than a predetermined threshold value, the systemconcludes that the station is outside of an authorized geographical area. Such a station attempting toestablish a connection is characterized as an unauthorized station, and access to the wireless LAN isdenied. The system may also periodically verify that authorized stations remain within the authorizedgeographical area. A station that has moved outside of the authorized geographical area can be notifiedor denied further access to the wireless LAN.

Title: Method and device for multimedia streaming
Inventor: WANG RU-SHANG
IPC: H04N21/6377
Filed: 2004-02-25
Abstract: A method to provide to a sender (20) of RTP packets the actual receiver (50) buffer (54) fullness level in a receiver of the RTP packets at a certain time instant represented as remaining playout duration in time. The receiver sends in an RTCP report (26) the sequence number of a selected RTP packet in the receiver buffer and the time difference between the scheduled playout time of this packet and the current time. Based on this timing information, the sender calculates the amount of time it would take for the receiver buffer to empty if the receiver continues to playout at normal speed and no further RTP  packets arrive to the receiver buffer. This receiver buffer fullness level information can be used at the sender to adjust the transmission rate and/or nominal playout rate of the RTP packets in order to maintain a targeted receiver buffer fullness level.

Title: Distributed filesystem network security extension
Inventor: SHIEH JOHNNY MENG-HAN
IPC: H04L29/06
Filed: 2004-04-15
Abstract: A security protocol that dynamically implements enhanced mount security of a filesystem when access to sensitive files on a networked filesystem is requested. When the user of a client system attempts to access a specially-tagged sensitive file, the server hosting the filesystem executes a software code that terminates the current mount and reconfigures the server ports to accept a re-mount from the client via a more secure port. The server reconfigured server port is provided the IP address of the client and matches the IP address during the re-mount operation. The switch to a secure mount is completed in a seamless manner so that authorized users are allowed to access sensitive files without bogging down the server with costly encryption and other resource-intensive security features. No significant delay is experienced by the user, while the sensitive file is shielded from unauthorized capture during transmission to the client system.
