Title: Primary transfer for simplex mode forward-link high-speed packet data services in cdma systems
Inventor: KUMAR SARATH
IPC: H04B7/005
Filed: 2000-06-01
Abstract: A back haul architecture enables efficient primary transfer (i.e., transfer of the designation of primary base station from one base station to another). A frame selection/distribution (FSD) function queues packets of forward-link data -- to which sequence numbers have been assigned --for packet-mode transmission over the back haul only to one base station --the current primary base station -- where the packets are again queued for over-the-air transmission to the mobile unit. If and when it becomes appropriate to transfer the designation of primary base station to another base station, there may still be packets of data queued at the old primary base station awaiting transmission to the mobile unit. The old primary base station sends a message to the new primary base station indicating a particular sequence number that identifies the remaining packets of forward-link data queued at the old primary base station. The new primary base station then sends a message to the FSD function requesting transmission of those packets of forward-link data corresponding to the particular sequence number. The FSD function then transmits those requested packets of forward-link data to the new primary base station, which queues the requested packets for over-the-air transmission to the mobile unit. In this way, transmission of all of the forward-link data to the mobile unit is enabled without having to transmit the remaining queued packets of forward-link data from the old primary base station to the new primary base station over the back haul, thereby providing an efficient mechanism for primary transfer in wireless communications systems that support forward-link data transmissions only in simplex mode.

Patent CA-2316969-A1 (CA)
Inventor: KAUFMAN RALPH E
IPC: H04L27/36
Filed: 1999-01-06
Abstract: L'invention concerne un modulateur (210) et un démodulateur (310) en quadrature qui permettent d'obtenir un niveau requis de performances en réduisant au minimum la consommation de courant. Dans le modulateur (210) en quadrature, les signaux I et Q parviennent à deux paires de mélangeurs. Chaque mélangeur d'une paire de mélangeurs module un signal I ou Q à l'aide de la sinusoïde FI respective en phase ou en quadrature. Les signaux modulés I et Q provenant de chaque paire de mélangeurs sont additionnés. Les signaux provenant des additionneurs parviennent à une troisième paire de mélangeurs et sont modulés à l'aide des sinusoïdes HF respectives en phase ou en quadrature. Les signaux provenant de la troisième paire de mélangeurs sont additionnés et fournis comme signal modulé. A l'aide de cette topologie de modulateur (210) en quadrature, l'équilibre d'amplitude et l'erreur de phase du signal modulé sont rendus insensibles au déséquilibre d'amplitude et/ou à l'erreur de phase des diviseurs en quadrature utilisés pour produire les sinusoïdes FI et HF. De plus, comme les deux premières paires de mélangeurs et les deux paires subséquentes d'additionneurs fonctionnent à des fréquences FI, les conditions nécessaires (p. ex. largeur de bande et linéarité) aux performances de ces éléments peuvent être assurées avec une consommation de courant réduite. Le concept de l'invention peut en outre être adapté à un démodulateur (310) en quadrature.

Title: Simultaneous binocular assessment of multiple optic nerve and cortical regions in diseases affecting nerve condition
Inventor: JAMES ANDREW CHARLES
IPC: G06F3/00
Filed: 1999-03-30
Abstract: This invention concerns the detection of neural damage to the optic nerve, optic radiations and white matter of the visual brain indicative of various neurological disorders but with particular application to multiple sclerosis. The method involves simultaneous measurement of the shape and latency of responses to visual stimuli presented simultaneously in different parts of the visual field of the two eyes, separating out linear and nonlinear response components, and most particularly separating out binocular interaction responses to assess neural function within each half of the visual cortex. Because rough retinotopicity is maintained in the optic nerve, through the optic radiations and the visual cerebral cortex, stimulation of the separate parts of the visual field permits isolation of responses from different component parts of these neural elements and therefore from the results obtained an objective assessment of damage to these separate neural components can be made simultaneously.

Patent CA-2350779-A1 (CA)
Inventor: BRADBURY ANDREW RAYMON MORTON
IPC: C12N9/00
Filed: 1999-11-18
Abstract: This invention provides novel methods of generating large, highly diverse, nucleic acid (and hence polypeptide) libraries. The methods exploit the discovery that recombination, particularly recombinase recombination can occ ur between two or more constructs of the same type (e.g. having the same origin  of replication and/or the same regulatory or selectable markers). The method s thus involve introducing at least two members of an initial population of nucleic acid molecules into at least one cell under conditions were recombination (e.g recombinase mediated recombination) can occur between the  nucleic acids. The nucleic acid molecules preferably comprise two or more individual nucleic acids each of which consists of a nucleic acid sequence that is identical for each molecule and that includes an origin of replication; and a nucleic acid sequence that varies between members of said  population. Thus, a single type of construct is capable of mediates all of t he recombination events providing substantially greater efficiency and the creation of substantially larger and more diverse nucleic acid libraries.</S DOAB>
