Granted: 2001-03-20
Abstract: A method and system automatically activates a mobile station in a wireless communications network. The system includes an over the air activation function (OTAF) processor in the network that initiates an activation process in response to receiving a registration message from a mobile switching center serving the mobile station requesting the activation. Each mobile station has a unit of information stored into it at the time of its manufacture to enable it to request over the air activation. That unit of information is either the network routing address of the OTAF processor, or alternately, it is a value that is translatable into that address, either an OTAF ID number that is the same value for every mobile station or it is a sequentially serialized dummy value for the mobile identification number (a dummy MIN). When the mobile station is turned on for the first time in the network, it requests activation over the air by transmitting to the local mobile switching center a registration order. The registration order will include one of the three alternative forms of the information unit described above, either the routing address of the OTAF processor, or the OTAF ID number, or a dummy MIN.

IPC: B29C65/18
Filed: 1997-10-23
Granted: 2006-07-11
Abstract: A procedure for welding mitre-cut plastic frame profiles that have inserted seals. A procedure and an apparatus for performing the procedure are to be such that the elastic function of the seals that are; to be welded with the frame profiles in the area of the mitred joint is retained. For the period when the frame profiles (1) and the seals (2) are being welded, the inside section of the seal, which is :formed by the the seal lip and the attachment foot of the seal (2) in and adjacent to the plane of the mitred joint shall be covered by at least one mould part so as to conform exactly or nearly so to its shape and after the welding process the moulded part is moved out of the area of the seal (2). Covering the inside section of the seal in the area of the mitred joint with a mould part when the frame profiles and the seals are being welded prevents a weld bead from forming in the inside area of the seal, which could impair the elasticity of the seal in this area.     The procedure and the apparatus for performing the procedure are used when manufacturing frames from plastic profiles to be used in windows and doors.

Title: Procede et circuit de tarification dans des reseaux de communications
Inventor: SCHONBORN FRANZ
IPC: H04M15/28
Filed: 1997-09-11
Granted: 2005-11-15
Abstract: L'invention concerne un système de tarification dynamique des communications utile pour des réseaux analogues et numériques de communications. Ce procédé et ce système de tarification dynamique des communications se fondent sur le degré d'occupation du réseau au moment où une communication est demandée. L'occupation de toutes les lignes de connexion en amont de la ligne de raccordement de l'abonné est mesurée en continu, par exemple au moyen de groupes (11) de mesure de l'occupation qui comprennent un dispositif (2, 2') de mesure des communications couplé aux lignes de connexion ou aux faisceaux (8) de lignes de connexion et un précalculateur du tarif (12, 12') qui détermine dynamiquement l'importance du tarif momentané et le retransmet en amont au central de commutation supérieur dans la hiérarchie. Le tarif actuel et individuel est affiché chez l'abonné appelant. Une fois que les derniers chiffres de l'indicatif régional ont été composés, le calculateur (1) du tarif calcule le tarif applicable en ce moment à cette destination, sur la base de la mesure la plus récente des communications, et le retransmet à des fins d'affichage. Le système se met alors pendant une durée déterminée en état d'offre. Une fois que l'abonné appelant a pris une décision, soit la sélection est interrompue soit le tarif indiqué est appliqué pour calculer le coût de la connexion, une fois que le numéro du correspondant souhaité a été composé. Le coût réel de la connexion est affiché à la fin de la connexion chez l'abonné appelant, ou également chez l'appelé lorsque ce coût est réparti entre l'appelant et l'appelé. Dans des réseaux numériques, ce système dynamique de tarification des communications convient non seulement pour déterminer le tarif de communications vocales, mais surtout pour déterminer le tarif de tous types de communications électroniques, par exemple la transmission de données et d'images.

Abstract: In a wireless communications system (20), a beacon having a first radiation pattern (28) covering a portion of a subscriber service area (34) covered by a base station is transmitted. A subscriber (36) reception quality is then measured to produce a first beacon quality measurement (210). Thereafter, the first radiation pattern is changed to a second radiation pattern (32, 212), and a subscriber reception quality of the beacon transmitted with a second radiation pattern is measured to produce a second beacon quality measurement (214). In response to the first and second beacon quality measurements, a traffic channel radiation pattern (32) is selected (218), wherein such radiation pattern covers a portion of the subscriber service area. In a preferred embodiment, the beacon carrier frequency is the same as the traffic channel carrier frequency.

Abstract: On décrit un système de communication sur ligne de transport d'énergie, qui comprend une ligne électrique (40) munie d'une série de conducteurs (B, R, Y) pour acheminer des signaux de communications. Un ensemble de signaux de communications est couplé à la série de conducteurs, chaque signal étant couplé à un conducteur respectif de la série de conducteurs et la relation de vecteur de phase de l'ensemble des signaux de communications étant choisie de manière à réduire au minimum la radiation des signaux de communications émanant de la ligne électrique. La relation de vecteur de phase peut être obtenue par déphasage d'un ou plusieurs des signaux. Ce procédé permet de transmettre des signaux de communications à des niveaux de puissance plus élevés, et donc d'élargir la portée de la transmission tout en réduisant au minimum la radiation émanant de la ligne électrique.
