Title: Phosphoramidate-phosphodiester oligonucleotide chimera as primers
Inventor: KUIMELIS ROBERT G
IPC: C12Q1/68
Filed: 1998-08-28
Abstract: The invention relates to novel chimeric phosphoramidate oligonucleotides and their use in primer-extension methods such as DNA sequencing and nucleic acid amplification. The subject chimeric phosphoramidate oligonucleotides have both N3'-phosphoramidate linkages and phosphodiester linkages. The invention includes methods of primer extension using the subject chimeric oligonucleotides as primers. Primer extension methods of interest include nucleic acid amplification reactions, e.g. PCR, and polynucleotide sequencing reactions. In the primer extension methods of the invention, a chimeric phosphoramidate oligonucleotide primer is annealed to a polynucleotide template. After annealing, the chimeric oligonucleotide primer is extended by joining a nucleotide to the 3' end of the primer by a DNA polymerase catalyzed reaction. Other embodiments of the invention include methods of primer extension using phosphoramidate linkage containing polynucleotide templates.  Such methods include annealing an oligonucleotide primer (chimeric or otherwise) to a polynucleotide template comprising at least one phosphoramidate linkage. Nucleotides are added to the primer in a DNA  polymerase catalyzed reaction. Primer extension takes place across one or more of the phosphoramidate linkages in the template. The invention includes compositions comprising a chimeric phosphoramidate oligonucleotide of the invention and a divalent cation. Divalent cations serve to increase the binding affinity between the chimeric oligonucleotides of the invention and a polynucleotide template. Additionally, divalent cations may be used to stabilize the phosphoramidate linkages of the subject chimeric oligonucleotides against hydrolysis at elevated temperatures, such as the temperatures used in PCR and cycle sequencing. The subject compositions may further comprise a thermostable DNA polymerase such as Taq DNA polymerase.

Abstract: Détection dun terminal sans fil emporté depuis un site. Dans un premier mode de réalisation, une station de base est attribuée à chaque sortie du site. La station de base utilise une antenne directionnelle qui communique uniquement avec des terminaux sans fil au sein de la zone de sortie. Lorsquun terminal sans fil entre dans la zone de sortie et senregistre auprès de la station de base, la station de base transmet les informations denregistrement à un système de commutation sans fil qui amorce immédiatement un appel téléphonique à lutilisateur du terminal sans fil pour linformer que son terminal sans fil na pas été rendu. En variante, dans un troisième mode de réalisation, après enregistrement du terminal sans fil, la station de base plutôt que le système de commutation sans fil amorce un appel téléphonique à lutilisateur du terminal sans fil pour linformer que son terminal sans fil na pas été rendu. Dans un deuxième mode de réalisation de linvention, un signal de transmission séparé des fréquences utilisées pour une communication voix et données par le système de commutation sans fil est utilisé pour alerter le terminal sans fil du fait que le terminal sans fil se trouve dans une zone de sortie. Le terminal sans fil est réactif à cette alerte pour initier un appel au système de commutation sans fil afin dinformer le système de commutation sans fil de ce fait. Le système de commutation sans fil alerte alors lutilisateur via le terminal sans fil.

Title: Forward link transmission mode for cdma cellular communications system using steerable and distributed antennas
Inventor: WILLARS PER
IPC: H04B1/04
Filed: 1997-12-16
Abstract: A DS-CDMA cellular system (10) is provided that employs two forward link transmission modes (14, 16) in parallel. A conventional transmission mode (16) broadcasts a pilot channel that can be used by a conventional mobile station (22) to estimate and detect a dedicated traffic channel. The second transmission mode (14) transmits (via a sectorized or narrow lobe antenna system (18)) all information required by a new generation mobile station (22) to estimate and detect a traffic channel dedicated to that mobile station.  Consequently, DS-CDMA system operators can introduce the use of adaptive array antenna systems (18) or distributed antenna systems with new generation mobile stations (22), without terminating the use of the conventional mobile stations (22).
