Abstract: A method and system for effecting production, approval and downloading of audio programs via the Internet. An order for an audio program is placed by a customer using a personal computer connected by the Internet to a server system. The server system receives the customer order and sends to the customer options for preparing a script and selecting music types that are to be dubbed into the audio program. A draft audio program is prepared by a service provider and downloaded to the server system. The customer accesses the server system and previews the draft audio program. If the customer wants the draft audio program changed, the customer inputs the changes to the server system. A redrafted audio program is prepared and loaded on the server system.  This process is repeated until the customer approves an audio program for downloading to a memory device for later reproduction.

Title: Absolutely calibrated periodic filters and sources
Inventor: ZARKA ALAIN
IPC: H04B10/12
Filed: 2002-11-13
Abstract: A method and a system for filtering a user light beam using a periodic filter having a frequency response stabilized at an absolutely calibrated value are provided. A primary light beam is generated by a tunable laser source and portions thereof are filtered by an absolute reference filter and the periodic filter.  First the frequency of the laser source is automatically locked on the absolute reference filter, and then the frequency response of the periodic filter is locked relative to the frequency of the laser source. The frequency response of the periodic filter is therefore continuously maintained at the proper calibration. User input and output are provided to pass the user light beam through the stabilized periodic filter independently of the filter stabilization process. A broadband absolutely calibrated optical source and a method for absolutely calibrating an optical spectrum analysis device are also provided.

Abstract: La présente invention concerne un procédé permettant d'acheminer le trafic dans un réseau de communication, comme, par exemple, les paquets de données, depuis des noeuds sources vers des noeuds de destination, via des noeuds relais pouvant être choisis par l'utilisateur. Les noeuds relais forment un réseau superposé de noeuds exploités et gérés par un opérateur de réseau superposé. La communication entre les noeuds relais repose sur les services de transmission de paquets de réseaux intermédiaires qui sont exploités et gérés de façon indépendante par d'autres opérateurs. Pour toute paire source/destination, l'opérateur de réseau superposé peut choisir une séquence appropriée de noeuds relais de passage en fonction de la qualité de service requise et des performances des différents réseaux intermédiaires. L'invention permet de régler l'étalement du trafic entre deux points terminaux sur plusieurs artères relais alternatives.
