Abstract: Deux mémoires de positions d'utilisateurs permanents (HLR) sont associées l'une à l'autre par attribution de deux codes de capacité. Un premier code de capacité est utilisé pour fournir un soutien au système par l'une des mémoires (HLR) chaque fois que l'autre mémoire (HLR) est défaillante. Le second code de capacité est utilisé pour mettre à jour en permanence la base de données de l'une par la base de données de l'autre de ces mémoires, au moyen des informations d'abonnés les plus récentes. Lors d'une défaillance d'une mémoire HLR particulière, les points de transfert de signal (STP) associés réacheminent les signaux arrivant, destinés à la mémoire HLR défaillante, vers la mémoire HLR qui lui est associée. Cette mémoire HLR associée compare le code de point de destination du signal reçu avec son premier code de capacité, pour déterminer si elle est autorisée à traiter ce signal. S'il y a correspondance, la mémoire HLR associée traite de façon automatique et transparente le signal reçu, sans interruption ou retard de service. Chaque fois que l'une des mémoires HLR reçoit de nouvelles données d'abonnés, les mêmes données sont communiquées à l'autre mémoire HLR, par utilisation de son second code de capacité comme adresse de destination.

Granted: 2008-02-05
Abstract: A modular mounting system which allows a circuit board to be removed, inserted or replaced through the front of the mounting frame without deactivating power to the equipment, and in the preferred embodiment without detaching any external cables. Connections for external equipment are disposed along the rear edge of the circuit board, and a row of contacts for the internal connections is provided along the bottom edge of the circuit board. The system of the invention provides a releasable connector which retracts the connector pins into a housing when a circuit board is inserted or removed, thus eliminating the possibility of a contact on the circuit board touching a live connector pin. In the preferred embodiment the external connections are made through adaptors that plug into external cable connectors provided on a connector plate detachably affixed to the rear of the mounting frame. In the preferred embodiment the invention provides an actuating mechanism for the releasable connector which must be actuated in order to remove a circuit board, thus ensuring that the connector pins have disengaged from the circuit board contacts before a circuit board is moved. The mounting system of the invention achieves a high packaging density for mounted devices and accommodates any input/output format. The invention also permits use of two or more separate circuit boards for a device residing in the same compartment and connected by an interface, which allows circuit boards to be repaired or upgraded by replacing a portion of the device circuitry. The invention also provides a novel system for cooling the mounting frame, providing heat sink tunnels in the impeller airstream and affixing the most significant heat-generating components to the heat sink tunnels. The impeller draws an intake airstream through a low resistance path within the mounting frame to cool the circuit board components.

Abstract: A method and apparatus which laterally focusses aqueous ink drops onto a substrate, using electric fields. The drops are not charged, and focusing results from the forces on the uncharged dielectric drop that occur in a nonuniform electric field. It is shown that initial lateral velocity misdirection of the drops is corrected using electric fields.  Lateral velocities which would produce drop displacements of -50µm from their intended positions, at a height of 1mm above the ink surface, may be corrected to produce displacements of less than 2.5µm.
