Title: Etablissement d'un code secret initial comprenant des dispositifs de verification d'identite
Inventor: MOREAU THIERRY
IPC: H04L9/00
Filed: 1998-05-07
Granted: 2008-07-29
Abstract: Un émetteur offre n'importe quel type de service sécurisé par un code cryptographique secret affecté à un demandeur selon la présente invention, lequel comprend un processus d'enregistrement de code secret. Habituellement, le code secret est chargé dans un dispositif de mémoire portatif ou une autre mémoire de code secret du demandeur. A titre d'étapes préliminaires, l'émetteur constitue son code public pour le cryptosystème d'échange de codes de cryptage probabiliste (PEKE), et le demandeur obtient une copie d'un logiciel d'enregistrement de code secret, une copie du code public de l'émetteur et un dispositif à mémoire portatif non initialisé. Une fois lancé par le demandeur, le logiciel d'enregistrement produit un code secret PEKE intérieur. Le demandeur choisit une demande de passage d'enregistrement et une réponse de passage d'enregistrement spécifiant les MAC du logiciel d'enregistrement et il crypte avec un code dérivé du code secret PEKE. Le logiciel d'enregistrement dérive le code affecté au demandeur du code secret PEKE, et il charge dans la mémoire le code secret. Un message est transmis au centre de traitement de données de l'émetteur où le traitement cryptographique (PEKE, MAC, cryptage) est inversé. Par un autre canal (par exemple conversation téléphonique) un agent émetteur vérifie l'identité du demandeur: l'agent effectue une interrogation de demande de passage, le demandeur répond avec la réponse de passage et l'émetteur vérifie la connaissance du demandeur de certaines données personnelles pertinentes. L'agent émetteur peut améliorer l'enregistrement du demandeur dans la base de données de l'émetteur. L'émetteur n'a pas besoin de personnaliser soit le logiciel soit la mémoire de codes secrets avant remise au demandeur et il existe un contact personnel individuel entre le demandeur et l'agent émetteur.

Title: Mobile switching center for providing wireless access ho
Inventor: BERGREN MARK H
IPC: H04W88/12
Filed: 2000-07-12
Granted: 2004-09-07
Abstract: The system for wireless communication connection handoff service addresses the CDMA radio congestion problem from the mobile switching center point of view, thereby providing a unified approach to the problem of access failures for CDMA wireless communication service. In operation, the mobile subscriber station forms a message and forwards it to the mobile switching center to indicate the signal strength of the various base stations that have responded to the access probe. The mobile switching center saves this data for later use when the mobile subscriber station moves out of range of the initially selected base station. The mobile switching center reviews the stored data and, if a CIC is available to one of the identified base stations, the channel is allocated and the stored data is flushed. Thus, the need for another probe sequence is avoided and the initially provided base station signal strength data is reused to process a call handoff.

Abstract: The present threaded joint comprises a coupling or threaded member in its internal surface in both of its ends -female- which joins a pair of members, each of them bearing external threads -male. The union between male and female ends is produced by means of the threaded surface. This joint is characterized in that the axial length of each male end is increased as compared to conventional joints. Further, each male end bears, on its free end at the vicinity of the threaded surface, an annular surface situated perpendicularly as regards the joint axis, such that once joined to the female end, said annular surface contacts the homonymous annular surface of the other male end which joins the other female end. Through the combined action of both effects, a higher resistance against joint jump-out upon combined loads action (bending, tensile, etc.) is achieved.

Abstract: The present invention relates to a base station having a receiver and transmitter for communicating with at least one mobile station having a receiver and transmitter. The mobile station transmits a mobile station identification number which is received by the base station when the mobile station comes into proximity with the base station. The base station is comprised of a list of mobile station identification numbers stored in the base station corresponding to mobile stations which are currently granted registration privileges. The list additionally comprises status information regarding the current state of the mobile station. A comparator is adapted to compare the mobile station identification number received from the mobile station with each of the mobile station identification numbers on the list of mobile station identification numbers and to output a signal indicating whether a match occurred. A transceiver is in communication with the comparator. The transceiver is adapted to process the communication from the mobile station to the base station when the comparator indicates that a match has occurred.

Abstract: A lubrication system for a railroad locomotive applies a lubricant with grea t accuracy in computer-controlled, precise quantities behind the last axle of the locomotive such that the lubricant is consumed b y the time the entire train has passed under all track, speed, temperature and train size condition. Hydraulic pulse-width modulation (PWM or %PWM) controls the quantity of lubricant delivered. Time is divided into a series of windows (33, 34, 35) each consisting of a f ew seconds. Lubricant delivered from a pressurized tank (8) through long hoses to a solenoid controlled valve (12) is then metered by th e duration within this time window (33, 34, 35) for which the computer computes and opens the valve (12). Compensation is provided for train tonnage and lubricant temperature as well as track curvature and train speed.

Title: Stent delivery system using shape memory retraction
Inventor: BICEK ANDREW D
IPC: A61F2/06
Filed: 2000-03-24
Granted: 2008-07-22
Abstract: The inventive stent delivery system includes a catheter having a retractable outer sheath near its distal end. A shape memory contraction member having a memorized contracted shape is connected to the retractable outer sheath. A heat generating device connected to the shape memory contraction member causes the shape memory contraction member to heat up to its transition temperature and assume its contracted position, retracting the retractable outer sheath. Another embodiment utilizes 2 springs, a"normal" spring and a shape memory alloy (SMA) spring, the two springs selected and designed so that the "normal"  has an expansion force which is less than SMA spring when the SMA spring is austenitic, but greater than the SMA spring when the SMA spring is martensitic. Yet another embodiment utilizes a shape memory latch which in its martensitic state abuts a stop to prevent a spring from moving the sheath proximally, but in its austenitic state releases the stop, allowing the spring to retract the sheath to release the stent for deployment.

Title: High performance cannulas
Inventor: VON SEGESSER LUDWIG K
IPC: A61B17/00

Granted: 2009-07-21
Abstract: Provided is a high performance cannula having a proximal end, a distal end, and a lumen extending between the proximal and distal ends, wherein the diameter of the lumen of the cannula can be varied to take into account differences in the diameter of access and target vessels during cannulation. The cannula is characterized by a narrow diameter at the point of insertion that does not adversely impact the flow rate of fluids through the cannula. The cannulas according to this invention produce a small access aperture and are characterized by flow rates that are at least as effective as those of conventional cannulas that produce larger access apertures.
