Patent CA-2415504-A1 (CA)
Inventor: BAUR AL J C
IPC: H04Q11/00
Filed: 2002-12-30
Abstract: The biggest bottleneck in the Internet today is caused by the slow speed of roofers, compared to the speeds that are achieved by optic fibers with DWDM (Dense Wave Division Multiplexing). Packet switching or something similar to it is needed not just for better utilization of the lines, but also because it is superior to circuit switching in many ways, such pus better scalability as the Internet grows, better handling of traffic congestions, and better routing flexibility. But optical routers are currently unable to do packet switching except by translating the data to electronic data and then back, which is very inefficient. The present invention solves this problem by optically marking and detecting the packet headers or parts of them, translating at most only the headers or parts of them to electronics for making packet switching decisions, and keeping the rest of the packets in optical delay lines, and solving response-time problems in the roofer, so that the crude optical switches can execute the packet switching decisions at fast bit rates. This solution has very high scalability and becomes even more efficient when physical addresses are used. Another optimization described in this invention is improving routing efficiency and bandwidth utilization by grouping together identical data packets from the same source going to the same general area with a multiple list of targets connected to each copy of the data and sent together to the general target area. These grouped packets ate then preferably broken down into smaller groups by the roofers in the general target area and finally broken down to individual data packets for delivering to the final actual destinations. This optimization works best with Physical addresses, and can be very useful for example for optimizing the access to very popular sites such as for example Yahoo or CNN, and can be used also for example for more efficiently transferring streaming data, such a a for example from Internet radio stations, or Internet TV stations which will probably exist in the next years. Another important optimization is a new architecture and principles for routing based on physical geographical IP addresses (such as for maniple based on GPS), in a way much more efficient than has been previously discussed in the literature that suggested using physical (geographical) addresses. However, conversion from the current architecture to the new one can be dose very easy, as shown in the description below.

Title: High-temperature fuel cell power station having reduced carbon dioxide emissions
Inventor: THOM FRANK
IPC: H01M8/124
Filed: 2001-07-21
Abstract: Fuel cell power stations have established themselves as methods for producing electricity, heat and hydrogen from fossil fuels. Up to now, the resulting CO2 can be liquefied and subsequently stored or deposited in beds only by using complicated techniques. According to the inventive method, the majority of the carbon, which is located inside the fuel that contains hydrocarbons, is converted into solid carbon before the actual electrochemical reaction inside the fuel cell. The solid carbon can then be easily passed out of the system and no longer presents any threat to the environment. The resulting carbon constitutes a valuable product, which can be utilized for other process steps or sold.

Title: Polarisation insensitive optical amplifiers
Inventor: EVANS IVAN
IPC: H01S5/50
Filed: 2003-03-14
Abstract: A planar waveguide module 1 has integrally formed thereon a waveguide 2 and, in sequence along the optical transmission path, a first LOA 3, a 90°  polarisation rotator 4, a VOA 5 and a second LOA 7. The LOAs 3 and 7 are gain-clamped SOAs having linear gain responses over the required wavelength range. In the absence of the polarisation rotator 4 the PDGs of the LOAs would be added together to provide an overall PDG of approximately twice the PDG of a single LOA. However the inclusion of the polarisation rotator 4 between the LOAs 3 and 7 causes a substantial reduction in the overall PDG. If TE polarised light is supplied to LOA 3, the polarisation rotator 4 will cause TM polarised light to be supplied to LOA 7, and accordingly the overall gain of the module will equal Gain(TE, LOA 3) + Gain(TM, LOA 7) - attenuation. On the other hand, if TM polarised light is supplied to LOA 3, the overall gain will be Gain(TM, LOA 3) + Gain(TE, LOA 7) - attenuation which is substantially the same as the gain for the inputted TE polarised light. Such a polarisation insensitive optical amplifier is advantageous since it is easily fabricated using known fabrication techniques, for example on a planar lightwave circuit on a SOI platform, and without having to modify the amplifying means.

Title: Novel approach to design glycopeptides based on o-specific polysaccharide of shigella flexneri serotype 2a
Inventor: MULARD LAURENCE
IPC: A61K47/48
Filed: 2003-07-04
Abstract: Both intestinal secretory IgA (SIgA) and serum IgG specific for the O-antigen (O-Ag), the polysaccharide part of the bacterial lipopolysaccharide (LPS) are elicited upon Shigella infection, the causative agent of bacillary dysentery. We have addressed here the protective role of the anti-LPS IgG response, using the marine model of pulmonary infection. Upon intraperitoneal (i.p.) immunization writh killed Shigella flexneri 2a bacteria, mice were shown to elicit a serum, but not a local, anti-LPS IgG response that conferred only partial protection against intranasal (i.n.) challenge with the homologous virulent strain.  However. mice intranasally administered with, prior to in challenge, an anti-LPS IgG  polyclonal serum from i.p. immunized mice, showed a significant antibody dose-dependent decrease of the lung-bacterial load in comparison to mice that received preimmune serum. Using marine monoclonal antibodies (mAbs) of the G isotype (mIgG) representative of the different IgG subclasses and specific for serotype-specific determinants on the O-Ag, we showed that each IgG subclass exhibited a similar serotype-specific protective capacity, with significant reduction of the lung-bacterial load and of subsequent inflammation and tissue destruction. In contrast, different subclasses of mIgG specific for the invasins IpaB or IpaC  did riot confer protection. In conclusion, the IgG-mediated systemic response to serotype-specific determinants contributes to protection against homologous Shigella infection, if the effectors are present locally at the time of mucosal infection.
