Filed: 1998-07-28
Abstract: Appareil et méthode d'entrée de dictée universelle, utilisant de multiples dispositifs de dictée sans fils (WDD) et des stations de base comprenant chacune une radio de 900 MHz pour communiquer entre elles sur des paires de canaux RF sélectionnées aux fins de sessions de dictée sur des systèmes de dictée centralisés (CDS). Une paire de canaux unique est affectée à chaque station de base. Les WDD sont programmés au moyen d'un code représentant les canaux exclusifs d'un choix déterminé de stations de base. Au décrochage, un WDD effectue un balayage séquentiel et cyclique des porteuses des stations de base autorisées jusqu'à ce qu'une station de base libre soit identifiée et qu'une liaison avec elle soit établie sur le canal autorisé. L'utilisateur de WDD doit avoir l'autorisation voulue pour les sessions de dictée sur un CDS ou plus.  cette fin, le WDD comprend un clavier multifréquence (DTMF) pour l'adressage de CDS autorisés. Les CDS sont des systèmes de tiers adressés à partir d'un WDD au moyen de caractères numériques de sélection DTMF. Les sessions de dictée utilisent des commandes de dictée envoyées aux CDS, p. ex. « enregistrement » et « écoute », sous la forme de caractères numériques DTMF. Les WDD envoient des paquets de données ASCII à une station de base. Les données transmises comprennent des caractères numériques de sélection. Les WDD génèrent des données à partir des touches programmables du clavier de sélection, personnalisées afin de transmettre à un CDS les commandes de dictée souvent utilisées et d'offrir d'autres fonctions spécialisées ainsi qu'un lecteur de codes à barres. Des données de configuration particulières sont transmises à une station de base afin de lui permettre d'exécuter des commandes et des caractères numériques de sélection particuliers aux CDS de différents fournisseurs, et de se préparer pour recevoir des commandes verbales de dictée. Une station de base comprend un algorithme de reconnaissance vocale afin de traduire les commandes verbales entrées à un WDD, p. ex. « enregistrement » et « écoute », en codes transmis à un CDS sous forme de caractères numériques DTMF.

Title: System and method for voice dialing
Inventor: RUBIN ROBERT MICHAEL
IPC: H04Q3/66
Filed: 1999-04-27
Abstract: A system and method provides a voice dialing service to a caller within a public switched telephone network (PSTN). The voice dialing service may supplement or replace existing directory services accessible through the PSTN. For example, by calling the voice dialing service and uttering the name of a city and state, the caller may be automatically connected to directory service listings for the locality including that city and state. In addition, the caller may utter the name of a company pursuant to the voice dialing service and automatically be connected to a national or local office of that company. According to the method, a caller places a call to the voice dialing service using a service number. The call is received at a switch within the PSTN. Without authenticating the caller as a subscriber of the service, the caller is prompted to speak a company name. The spoken company name is received at the switch as an analog signal which is then digitized. Subsequently, the switch queries a database with the digitized spoken company name. The database includes a plurality of speech models, each speech model corresponding to a company name. In addition, the database has at least one destination number corresponding to each speech model. The speech model within the database having the closest match to the digitized spoken company name is identifying.  Then, one of the destination numbers corresponding to the identified speech model is selected which is used to route automatically the call to the selected destination number.

Title: Heat exchanger with dimpled bypass channel
Inventor: CHEONG ALEX S
IPC: F28F3/04
Filed: 1999-05-28
Abstract: A heat exchanger is disclosed having a plurality of stacked plate pairs or tubes, each having a predetermined internal cold flow resistance. A bypass conduit is included in the stack of plate pairs or tubes. The bypass conduit includes a central row of spaced-apart, mating dimples defining longitudinal flow channels on either side of the dimples for bypass flow through the bypass conduit under cold flow conditions. The longitudinal flow channels have a height and width such that the cold flow resistance therethrough is less than the cold flow resistance through the stacked plate pairs or tubes. In normal or hot flow conditions, the dimples create flow resistance by forcing the fluid flowing through the bypass conduit to change velocity and direction. This forces more oil to flow through the stacked plate pairs or tubes increasing heat transfer performance.
