Title: Systeme de communication par satellite pour couverture de zone locale
Inventor: CHENNAKESHU SANDEEP
IPC: H04W84/14
Filed: 1997-04-25
Abstract: Système de communication permettant une communication par satellite efficace dans des zones rurales, éloignées ou à faible densité de population, ou dans des zones ne disposant pas d'une infrastructure téléphonique traditionnelle, ou encore destinée à être utilisée à des fins spéciales, telles que la couverture d'un aéroport. Les abonnés se trouvant dans ces zones communiquent avec le satellite via un noeud d'entrée simple hautement modulaire situé dans une zone locale à desservir. Des unités d'abonnés fournissent l'accès au système à des abonnés. Lesdites unités d'abonnés sont connectées au noeud d'entrée par l'intermédiaire de boucles d'accès locales fournies par des liaisons sans fil de point à point entre les unités d'abonnés et le noeud d'entrée. Le noeud d'entrée commute de manière interne les communications locales entre abonnés et connecte les communications avec des circuits extérieurs, par l'intermédiaire de liaisons sans fil avec le satellite, lorsque cela est approprié. Les circuits extérieurs sont fournis par le fonctionnement en coopération du satellite, d'un dispositif de commande de noeud d'entrée et d'une station terrestre. Les liaisons sans fil entre le satellite et le noeud d'entrée et les boucles d'accès locales peuvent fonctionner à des fréquences identiques ou différentes. Si elles fonctionnent à des fréquences différentes, un transposeur de fréquence dans le dispositif de commande de noeud d'entrée apparie les différentes fréquences. Une unité d'abonné peut être utilisée pour fournir aux abonnés un accès au système, de telle manière que la compression et la décompression vocale aient lieu dans l'unité d'abonné elle-même afin d'éviter les effets de codeurs/décodeurs en tandem.

IPC: C04B35/622
Filed: 1998-11-24
Abstract: Methods and apparatus for the preparation of a substrate having an array of diverse materials in predefined regions thereon. A substrate having an array of diverse materials thereon is generally prepared by depositing components of target materials to predefined regions on the substrate, and, in some embodiments, simultaneously reacting the components to form at least two resulting materials. In particular, the present invention provides novel masking systems and methods for applying components of target materials onto a substrate in a combinatorial fashion, thus creating arrays of resulting materials that differ slightly in composition, stoichiometry, and/or thickness. Using the novel masking systems of the present invention, components can be delivered to each site in a uniform distribution, or in a gradient of stoichiometries, thicknesses, compositions, etc. Resulting materials which can be prepared using the methods and apparatus of the present invention include, for example, covalent network solids, ionic solids and molecular solids. Once prepared, these resulting materials can be screened sequentially, or in parallel, for useful properties including, for example, electrical, thermal, mechanical, morphological, optical, magnetic, chemical and other properties.

Filed: 1998-10-27
Abstract: Heterogeneous assays for different analytes in a single biological sample are performed simultaneously in a multiplexed assay that combines flow cytometry with the use of magnetic particles as the solid phase and yields an individual result for each analyte.  The particles vary in size to encompass distinct size ranges that are distinguishable by flow cytometry, the particles in each size range carrying an assay reagent bonded to the particle surface that is distinct from the assay reagents of particles in other size ranges. The magnetic particles facilitate separation of the solid and liquid phases, permitting the assays to be performed by automated equipment.

Title: Apparatus and method for interpreting and intelligently managing electronic messages
Inventor: ABU-HAKIMA SUHAYYA
IPC: H04W4/00
Filed: 1999-05-25
Abstract: A computer-readable system and method for interpreting and selectively forwarding an interpreted message derived from a user's received electronic message, such as an e-mail, fax, converted voice and pager messages, to a mobile communications device of the user. A structured knowledge base comprises knowledge objects of user-related information and the knowledge objects are interlinked by semantic links to permit dynamic navigation thereof. Navigating means dynamically navigates through the structured knowledge base using the content of the received message and determines key term(s) relating to the content as a result of the navigating. An interpreted message is determined from those key term(s). Prioritizing means determines the priority of the message, selects the second communications device based on the current context of the user and the content of the message in relation to the user-related information and assigns priority indicia to the interpreted message according thereto. Forwarding means forwards the interpreted message to the second communications device when the priority indicia assigned to the interpreted message represents that the interpreted message is to be so forwarded.
