Filed: 2000-11-22
Granted: 2005-01-18
Abstract: Pour mesurer in situ la tension résiduelle F1 d'une barre de précontrainte tendue entre deux ancrages, on mesure le temps d'aller-retour T1 d'une onde ultrasonore entre les deux extrémités de la barre, et on évalue F 1 par la formule F1 = F0 + k b.(T1-T0). Lors d'un étalonnage préalable effectu é sans démontage, on soumet la barre un effort de traction variable F, on mesu re pour chaque valeur le temps d'aller-retour T d'une onde ultrasonore entre le s deux extrémités de la barre, on enregistre une courbe (C) associant l'effort F au temps T, on détermine la constante T0 comme étant le temps d'aller-retour T mesuré pour F = 0, on approche la courbe, au voisinage de la valeur F = 0, par une première droite (D1) de pente k a, on approche une portion supérieur e de la courbe par une seconde droite (D2) de pente k L, on détermine la constante F0 comme étant l'effort de traction F correspondant au point d'intersection des première et seconde droites, et on détermine la constante k b selon la relation 1/k b = (1/k L) - (1/k a).

Abstract: Tone sequences in a frequency hopping arrangement are generated and assigned by advantageously employing a combination of a sequence generator and a sequence assignor to generate sequences and assign them on a time slot by time slot basis. In a transmitter, the sequence generator and sequence assignor, in combination with a user tone assignor are employed to generate and assign tone sequences to a user on a time slot by time slot basis. In a receiver, the sequence generator and sequence assignor, in combination with a user tone identifier are employed to generate sequences and to identify incoming tone sequences to a user on a time slot by time slot basis. Specifically, the sequence assignment in a time slot is such that a prescribed plurality of sequences is assigned to a particular user. This partitioning of the tasks facilitates the use of a sequence generator that generates sequences with the desirable properties of interference and frequency diversity and, which, leaves the task of properly assigning these sequences among one or more users to the sequence assignor. The sequence assignor functions in such a manner that the interference and frequency diversity properties for the one or more users are preserved, and this is further facilitated by assigning sequences in such a manner that they maximally overlap prior assigned sequences. In one embodiment of the invention, a Latin square based sequence is generated in accordance with a first prescribed process. In a second embodiment of the invention, a Latin cube based sequence is generated in accordance with a second prescribed process. In a third embodiment of the invention, a Latin hypercube of prescribed dimension based sequence is generated in accordance with a third prescribed process. In still another embodiment of the invention, the principles of the invention are employed to realize frequency band hopping.

Title: Apparatus, method and system for providing a default mode for authentication failures in mobile telecommunication networks
Inventor: BOLAND RICHARD ROBERT
IPC: H04M3/00
Filed: 2001-04-17
Granted: 2005-06-07
Abstract: An apparatus, method and system are disclosed for providing a default mode for authentication failures in a mobile telecommunication network. The system includes an authentication center (typically co-located within a home location register), an adjunct network entity, and an originating mobile switching center. The home location register generally stores information pertaining to a mobile unit, such as a cellular or PCS mobile telephone. The adjunct network entity contains one or more application nodes, such as an announcement application node for providing an announcement on a call leg to the mobile unit. When the network has been accessed by a mobile unit through a call leg, the originating mobile switching center is configured to perform an authentication procedure. The originating mobile switching center further is configured, when the authentication procedure has resulted in an authentication failure, to receive a message from the authentication center to deny the mobile unit access to the network, to terminate a communication session with the mobile unit, and to route the call leg to the announcement application node for the provision of an announcement on the call leg to the mobile unit. Following such an announcement, the originating switching center is also configured to route the call leg to a customer service center, for example, to reprogram the mobile unit.

Abstract: A vapor compression system (10) includes an evaporator (16), a compressor (12), and a condenser (14) interconnected in a closed-loop system. In one embodiment, a multifunctional valve (18) is configured to receive a liquefied heat transfer fluid from the condenser (14) and a hot vapor from the compressor (12). A saturated vapor line connects the outlet of the multifunctional valve (18) to the inlet of the evaporator (16) and is sized so as to substantially convert the heat transfer fluid existing the multifunctional valve (18) into a saturated vapor prior to delivery to the evaporator (16). The multifunctional valve (18) regulates the flow of heat transfer fluid through the valve (18) by monitoring the temperature of the heat transfer fluid returning to the compressor (12) through a suction line (30) coupling the outlet of the evaporator (16) to the inlet of the compressor (12). Separate gated passageways within the multifunctional valve (18) permit the refrigeration system to be operated in defrost mode by flowing hot vapor through the saturated vapor line (28) and the evaporator (16) in a forward-flow process thereby reducing the amount of time necessary to defrost the system and improving the overall system performance.
