Abstract: A method and system are disclosed for mediating signalling protocol dialogue  between an internal signalling network operational domain operated by one network operator and an external signalling network operational domain operated by another network operator. One embodiment provides a method of dividing the SS7 traffic (Message Signal Units or MSUs) arriving for Mediation, into classes such that network performance requirements can be me t, wherein some message classes will receive only normal SS7 processing while others will be analyzed in detail. MSUs requiring detailed analysis must be routed to a mediation application process appropriate to that class. Another  embodiment provides a method of manipulating Signalling Connection Control Part (SCCP) address parameters in the SMP in order to maintain normal SS7 message processing and routing functions while mediating individual messages . Yet another embodiment provides a method enabling the SMP to route a receive d MSU on toward its intended final destination based on information encoded in  the Message Transfer Part (MTP) addresses contained in the MSU.

Title: Use of bisphosphonates for the treatment of osteogenesis imperfecta
Inventor: ROLDAN EMILIO J A
IPC: A61K33/16
Filed: 2000-05-11
Granted: 2005-11-29
Abstract: The present invention relates to a procedure applicable to medical preparations of bisphosphonates and their formulations for the treatment of Osteogenesis Imperfecta. This procedure consists of the administration of bisphophonate preparation to a patient requiring treatment in a first stage to obtain a defined bone mineral density.  Then the administration of the bisphosphonate preparation is interrupted in a second stage to allow for architectonic expression of bone. The length of the second stage can be determined by means of a tomography. In other words, the periods of administration or non-administration of the mineralizing agent are defined or controlled by precise osteologic variables and therefore are not fixed. If during the second stage the cortical mineral density drops by 6-10% of the maximum value previously obtained, administration of bisphosphonate preparation should be resumed until the corresponding maximum adjusted value is reached again. The proposed procedure of a period comprising bisphosphonate administration followed by a period of non-administration of the bisphosphonate agent improves fracture resistance, provided that the length of both periods is controlled by defined osteologic variables.

Title: Procede et appareil servant a produire des matrices de seuils en minimisant la variance et en calculant les angles des pixels
Inventor: PETERS MICHAEL ALAN
IPC: H04N1/405
Filed: 1998-10-01
Granted: 2001-08-28
Abstract: Cette invention concerne un procédé et un appareil permettant de créer des matrices de seuils à partir d'une minimisation de la variance de l'échelle des gris sans artefacts géométriques. L'invention consiste à transformer chaque pixel candidat dans la matrice de seuils au moyen d'une technique de minimisation de la variance et à appliquer un calcul d'images dispersées au même pixel. Selon un mode préféré, cette invention consiste à appliquer une technique de minimisation de la variance à une matrice de seuils. Cette matrice de seuils est analysé pixel par pixel. Tout pixel candidat qui doit être mis sous tension est examiné par rapport aux pixels préexistants. Cet examen vise à faire apparaître les effets sur la variance du niveau des gris lissés déterminé par la convolution de la configuration des pixels au moyen d'un noyau de lissage. L'examen du pixel candidat porte également sur la distribution des angles que ce pixel forme avec les pixels présélectionnés. Selon le mode préféré de l'invention, on recourt à la transformée combinatoire de Hough; il y a une matrice d'accumulateurs pour tout pixel non encore sélectionné qui a un position pour chacun des jeux quantifiés d'angles. Une somme est mémorisée à cette position sur la base des pixels précédemment sélectionnés qui forment avec le pixel non encore sélectionné un angle qui est discrétisé par rapport à l'angle correspondant à cette position. L'effet de l'angle réel peut être réparti sur plus d'un point de la matrice d'accumulateurs et peut dépendre de la distance et de l'angle. Le pixel sélectionné doit combiner une faible variance du niveau des gris lissés et une distribution favorable des valeurs dans sa matrice d'accumulateurs à angles correspondants. Ce processus est répété jusqu'à ce que tous les pixels de la matrice de seuils aient été sélectionnés.

Abstract: This invention provides a measurement-while-drilling (MWD) downhole assembly for use in drilling boreholes which utilizes gyroscopes, magnetometers and accelerometers for determining the borehole inclination and azimuth during the drilling of the borehole. The downhole assembly includes at least one gyroscope that is rotatably mounted in a tool housing to provide signals relating to the earth's rotation. A device in the tool can rotate the gyroscope and other sensors on the tool to one of a plurality of preselected positions and optionally lock the sensors. A processor in the tool combines measurements from the sensors taken at a plurality of positions at the same depth to determine the systematic bias in the sensors before further processing. Accelerometers in the MWD tool provide gravity measurements from which the toolface and inclination are determined. The unbiased gyroscopic measurements are used in conjunction with the tool face and inclination measurements to determine the azimuth and tool face with respect to true north. Additionally, when measurements are made with magnetic, accelerometer and gyroscopic measurements along three different axes, the unbiased measurements may be combined to provide an improved determination of the tool orientation. Using the locking mechanism, measurements may be made with the sensor housing locked in place during continuing drilling operations. When used with a drilling liner system, the sensor assembly may be retrieved using a wireline. With the present invention, a secondary borehole for secondary recovery operations may be drilled with accuracy in proximity to a producing borehole.
