Title: Multicell area paging for cellular telecommunications system
Inventor: LAGNEBORG JOHAN
IPC: H04W68/04
Filed: 1999-04-29
Granted: 2010-10-19
Abstract: A radio access network portion of a telecommunications network (18) which serves a mobile station (MS) is connecting to a core network. The radio access network portion has plural base stations (BS) serving respective plural cells (C), as well as plural control nodes (RNCs). The control nodes include a first control node (RNC1) for controlling a first group of the plural base stations and a second control node (RNC2) for controlling a second group of the plural base stations. A multicell area (MCA) includes cells served by at least some of the first group of base stations and cells served by at least some of the second group of base stations. The radio access network portion of a telecommunications network further has a paging control node which stores information regarding the multicell area. To page the mobile station in the multicell area, the paging control node (1) sends paging messages to each of the base stations serving the multicell area controlled by the paging control node; and (2) sends a paging message to any other control nodes which control base stations serving cells in the multicell area. The paging control node determines to which base stations and other control node(s) it should send paging messages by consulting a paging table (100). Perferably the paging control node is one of the control nodes of radio access notwork. The paging control node is connected to the other control node(s) by an intercontrol node link (32) over which the paging message is sent.

Abstract: A downhole NMR measurement apparatus for use in a borehole includes at least one magnet, at least one RF transmission coil, at least one gradient coil and circuitry. The magnet(s) establish a magnetic field in a region of a formation that at least partially surrounds the measurement apparatus. The RF transmission coils(s) transmit RF pulses pursuant to an NMR pulse sequence into the region to, in combination with the magnetic field, induce the generation of spin echo signals from a resonance volume within the region. The gradient coil(s) establish a pulsed gradient field in the resonance volume, and the circuitry is coupled to the gradient coil(s) to control the generation of the pulsed gradient field to phase encode the spin echo signals for purposes of high resolution imaging of the formation.

Granted: 2009-10-06
Abstract: A technique for restoring operation to a plurality of cells within a wireless communication system includes the step of estimating the traffic within each cell to provide a plurality of traffic measurements. These traffic measurements are stored. In the event of a disruption in service provided by the communication system, the measurements are retrieved. The system then restores operation to cells within the wireless communication system in an order based on the retrieved traffic measurements, e.g., such that the cell which had the heaviest traffic at the time of system disturbance is restored before other cells. This maximizes the revenue produced by the system and minimizes customer dissatisfaction.

Abstract: A certificate validity verification engine is integrated into the logic of a secure token, in turn, making the use of a private key conditional upon the determination that the certificate for the corresponding public key is valid at that particular instant in time. In this manner, the existence of a digital signature that is verified with a certificate implies that the certificate was valid at the time the signature was created. The verification of the certificate's validity by the relying party is unnecessary, as the signature could not have been created had the certificate been invalid. The validity of a certificate is communicated at the time the signature was created, rather than at the time the signature was verified.

Abstract: Dispositif à sécurité intégrée ou mécanisme de relâchement de pression conçu pour un organe de commande d'unité d'introduction de machine de moulage par injection. Cet organe de commande possède des tiges-poussoirs (228) multiples montées sur une ou plusieurs plaques (224). Le déplacement de la plaque (224) maintenant les tiges-poussoirs (228) enfonce les pistons d'injection de l'unité d'introduction et injecte du matériau en fusion dans plusieurs cavités de moulage. Dans le but d'éviter la détérioration de la machine par les tiges-poussoirs (228) dans le cas du grippage d'un piston d'injection, on utilise un dispositif (250) à sécurité intégrée afin de fixer les tiges-poussoirs (228) aux plaques (224). On intercale un élément de cisaillement entre la première et la deuxième ouvertures (258, 260 262). Cet élément de cisaillement (254) est normalement une plaque qui, dans des conditions de fonctionnement normales, bloque le recul de la tige-poussoir (228). Cependant, quand on applique une force de cisaillement prédéterminée à la plaque de cisaillement, l'élément de cisaillement (254) effectue un mouvement de cisaillement et la tige-poussoir se retire à l'intérieur du canal, ce qui soulage la pression. Ce dispositif à sécurité intégrée peut être accouplé à un système de détection de grippage mettant en application un faisceau laser détectant le grippage du piston et de l'entrée de la soupape et permettant d'obtenir une indication appropriée ou des signaux de commande.

IPC: A61B5/107
Filed: 2002-11-13
Granted: 2008-05-13
Abstract: A system and method for fitting footwear and footwear inserts provides a removable insert which measures the foot by thermal imaging. The insert is provided with a thermally sensitive layer, for example a thermochromic material having a color transition interval within the range between room temperature and body temperature, that thus reacts to the heat transferred from portions of the foot in contact with the insert and temporarily changes color. The insert retains an image of the footprint for a short interval after contact with the foot, and can be removed from the footwear to examine the position and size of the foot relative to the footwear insole (and thus relative to the footwear) when the footwear is actually worn. For inserts which are purchased separately for cushioning, odor-reduction etc., the footprint image can be used as a guide to cut the footwear insert to follow the shape of an individual's foot.
