Granted: 2009-12-15
Abstract: A method and means for simultaneously inserting weft/binding yarns (45) and their beating-up, in textile manufac-turing processes like 3D-weaving and uniaxial noobing, is disclosed. A yarn carrier (90, 39, 22) is equipped with a beating-up reed dent (27; 28). In carrier (90), which comprises a cartridge-like yarn supplying means (lx), the yarn (45) is arranged around two axes of rotation (X1 and X2) and it is enclosed in a case. It is particularly suitable for 3D textile-forming processes like 3D-weaving and uniaxial noobing because of its relatively low-height but high-width and hence the possibility of carrying relatively large amount of yarn. The yarn (45) is contained on a flanged belt (15) that can be driven either from within or from outside of the means (1x). Such a cartridge-like yarn supplying means (1x) is equipped with tips (18a, 18b) that are offset or displaced oppositely about the central axis. Such a displaced arrangement of the tips directs the carriers (90; 22) to lay yarn (45) in two different paths, relative to a layer of warp/axial yarns, while traversing back and forth in the same linear path.  Through such a method the 3D-weaving and uniaxial noobing processes can be made efficient. The yarn supplying means (lx) could also be useful in other textile processes.

Title: Apparatus and method for controlling transmission power in a mobile communication system
Inventor: JO SUNG-KWON
IPC: H04J13/00
Filed: 2002-07-10
Granted: 2008-01-22
Abstract: An apparatus and method for maximizing the efficiency of a power amplifier by reducing the PAPR of a BS in a mobile communication system. A power controller between I and Q channel pulse shaping filters and a frequency converter calculates cancellation signals for signal pulses that increase the PAPR at each sampling period, pulse-shape-filters cancellation signals at the highest levels among the cancellation signals, and adds the filtered cancellation signals to the original signals. Thus, spectral regrowth outside a signal frequency band is suppressed. In the case of a system supporting multiple frequency allocations, the PAPR is controlled for each FA according to its service class. Therefore, minimum system performance is ensured and power use efficiency is increased.

Title: Fold flat vehicle seat coincident with rearward travel
Inventor: SMUK WOJCIECH
IPC: B60N2/22
Filed: 2003-08-28
Granted: 2007-04-10
Abstract: A fold flat vehicle seat comprises a seat assembly mounted on a movable track member slidably engaging a fixed track member, and lockable by a track lock. The seat assembly includes a seatback member mounted on a seat cushion member for forward folding between a substantially upright occupiable design position and a substantially horizontal load supporting position. A downwardly and rearwardly sloped ramp is mounted on the fixed track member. A drive link assembly is mounted on the seatback member for translational engagement of a ramp contact member with the ramp. As the seatback member is forwardly folded from the upright occupiable design position to the load supporting position the track lock releases and the ramp contact member moves downwardly and rearwardly along the ramp to thereby cause rearward longitudinal movement of the seat assembly relative to the fixed track member to a predetermined rear longitudinal position.

Title: Protocole permettant de determiner des routeurs d'acces cibles optimum pour le transfert de niveau ip sans coupure

Granted: 2009-12-29
Abstract: La présente invention concerne un appareil et un procédé qui facilitent le transfert sans coupure de connexions IP entre des routeurs d'accès dans un réseau IP. Le réseau mobile IP comprend au moins deux routeurs d'accès qui desservent chacun une zone de service géographique différente. Lorsqu'un terminal mobile se déplace de la première zone de service et accède à la deuxième zone de service, le terminal mobile envoie au deuxième routeur d'accès l'adresse IP du routeur d'accès précédent. Le deuxième routeur d'accès utilise ces informations pour connaître les capacités du premier routeur d'accès (par exemple, les largeurs de bande supportées, les programmes de sécurité et autres) afin de les utiliser dans des décisions de transfert ultérieures, et échange avec le premier routeur d'accès des informations de capacité. Cette hypothèse est fondée sur les informations échangées qui indiquent que les routeurs d'accès sont géographiquement proches. Lorsqu'un autre terminal mobile passe d'une zone de service à une autre, le système sélectionne un routeur d'accès cible optimal sur la base des informations recueillies au préalable, y compris la proximité géographique inférée entre les routeurs d'accès.

Abstract: La présente invention concerne un système et un procédé permettant, dans un réseau de télécommunication, de facturer sur la base d'un compte rendu de charge du trafic dans le réseau une communication demandée par un utilisateur. Le système comporte au moins une fonction MGCF (Media Gateway Control Function) qui envoie à un serveur PIM (Presence and Instant Messaging) dans un message d'enregistrement un compte rendu de charge du trafic concernant le MGCF. Les utilisateurs qui s'abonnent à un tel service de facturation sur la base de la charge s'enregistrent également auprès du serveur PIM. Ce serveur PIM envoie aux utilisateurs le compte rendu de charge du trafic à chaque mise à jour de la charge du trafic par la MGCF, et au noeud de facturation lorsque l'utilisateur demande une communication. Une fonction CSCF (Call State Control Function) envoie au noeud de facturation la durée de la communication. Se basant sur le compte rendu de charge du trafic, le noeud de facturation détermine un taux de facturation puis il calcule le prix de la communication sur la base du taux de facturation déterminé et de la durée de la communication.
