Title: Method for common control of the bandwidths of a group of individual information flows
Inventor: SCHNEIDER PETER
IPC: H04L47/80
Filed: 2002-04-12
Abstract: The aim of the invention is to achieve a good utilization of the capacity of a transmission channel while ensuring guaranteed bandwidths for traffic flows transmitted over the transmission channel. To this end, the invention provides a method for transmitting traffic flows (1, 2, 3) over a common transmission channel (7) whose (1, 2, 3) data (A E) arrives in at least one buffer (4, 5, 6) connected upstream from the transmission channel (7). According to this method: a guaranteed bandwidth (BG 1) is determined for the transmission of packets (A E) of each traffic flow (1) over the transmission channel (7); a maximum bandwidth (B1 Max) is determined for the transmission of packets (A E) of each traffic flow (1) over the transmission channel (7), whereby packets (D  E) of a traffic flow (1), which arrive in a buffer (4) with a transmission rate less than the guaranteed bandwidth (BG 1), are chronologically transmitted over the channel (7) before the packets (ABC) of this traffic flow that arrive in buffer (4) with a transmission rate exceeding the guaranteed bandwidth (yellow, red), and; packets (ABC) of a traffic flow, which arrive in a buffer (4) with a transmission rate lower than the maximum bandwidth (B1 Max), are chronologically transmitted over the transmission channel (7) before packets (C) of the traffic flow (1) that have arrived in the buffer (4) with a transmission rate exceeding the maximum bandwidth (B1 Max) of the traffic channel in the transmission channel (7) (red).

Patent CA-2484991-A1 (CA)
Inventor: LIM NAE-HYUN
IPC: H04L12/56
Filed: 2003-05-13
Abstract: Disclosed is a method for providing a broadcast service in a mobile communication system using a CDMA technology. The method controls transmission of broadcast service data according to base station areas by registering a mobile station with a broadcast service. The mobile station requests an authentication server to authenticate a desired broadcast service, and registers the authenticated broadcast service in a packet data serving node via a base station so that the base station and the packet data serving node can set up a transmission path for the broadcast service. The method increases the efficiency of base station resources by controlling transmission times of base stations, and the packet data serving node can perform accounting on the broadcast service of the mobile station. Further, a plurality of registered mobile stations constitute a group, and broadcast service data is transmitted from one mobile station to other mobile stations within the group.

Patent CA-2490778-A1 (CA)
Inventor: SUBRAHMANYA PARVATHANATHAN
IPC: H04W52/48
Filed: 2003-06-25
Abstract: Methods and apparatus for reducing latency for communication error recovery includes recognizing that an incoming message is due, and requesting retransmission if that message is not properly received. A message is transmitted as two message portions, the first message portion transmitted at a first power level (220), and the second message portion, which is associated with the first message portion, transmitted at a second lower power level (230). The first power level is chosen to provide a predetermined probability that the first message portion will be successfully received. Alternatively, the first and second message portions are transmitted such that the first message portion has a greater energy per bit than does the second message portion. At a first time, the first message portion is received. At a second time, wherein the second time has a known relationship to the first time, a signal is received from which the second message portion is not reliably obtained. The receiving device recognizes that the second message portion was not properly received and requests retransmission of at least the second message portion.

Title: Optical brightener for aqueous high yield pulp and process for making brightened paper
Inventor: MOYLE BRADLEY EDWIN
IPC: D21C9/00
Filed: 2005-02-07
Abstract: Paper is brightened by addition of a tetrakis(hydroxyalkyl) phosphonium ("THP") salt in an amount greater than 0.04% but no more than 5% by weight in wet pulp. The amount of THP salt added is sufficient to enhance the brightness of paper made from fibers in the wood pulp to a desired brightness level. The THP salt is commercially available and previously used as a fire retardant and a biocide.  Though particularly useful in the production of brightened cellulose fibers of high yield pulp, with the benefit of generally improving opacity, the process may be used to treat all wet pulp which is to be brightened.
