Title: High speed weighted fair queuing system for atm switches
Inventor: HE LINHAI
IPC: H04L12/56
Filed: 1999-09-02
Abstract: Methods and apparatus for an ATM network for implementing a fair servicing of all connections during a back-logged condition through the use of a weighted fair queuing technique. The system is particularly suited for systems where the packets/cells ere of a fixed size. Although some important approximations are made in the proposed implementation, all of the properties of an ideal weighted fair queuing algorithm are preserved. The sorting methods and apparatus are advantageous in that it is possible to maintain appropriate servicing of connections without sorting all of the individual connections. This may be accomplished by pro-sorting each of the individual virtual circuit connections into a finite number of predetermined bins according to a weight associated with the connection. Thereafter, only the bins need be sorted without having to sort each of the individual connections. Further aspects of the invention include storing the bins in a matrix with an offset value dependent upon the current potential of the bin. In this manner, the overall sorting required to determine the next connection to service is substantially reduced. Accordingly, the invention is suitable for implementations having transmission speeds of multiple gigabits-per-second.

Title: Mri contrast media recognizing microenvironmental changes
Inventor: MARUYAMA ATSUSHI
IPC: A61K49/12
Filed: 1998-03-16
Abstract: Contrast media containing complexes of gadolinium (Gd)-base contrast media with polymers which undergo phase transition due to changes in pH value, light or temperature and thus become soluble in water; and a method of providing a contrast characterized by using these contrast media. Since the polymers responding to minor environmental changes are bonded to the Gd-base MRI  contrast media, the performance of the contrast media can be exerted exclusively at the target sites, thus enabling on-off switching of the performance of MRI contrast media. Therefore, the obtained contrast media are highly specific ones by which the contrast is provided not at the sites where no contrast is needed but exclusively at the target tumors or specific sites, thus ensuring highly specific MRI diagnosis.
