Title: Controle de congestion dans un noeud atm
Inventor: MILLES OLIVIER
IPC: H04L12/54
Filed: 1999-05-25
Abstract: L'invention concerne un procédé de contrôle de congestion dans un noeud d'un système de transmission asynchrone, dans lequel sont transmis des cellules formant des paquets; elle propose d'accepter ou de rejeter les cellules en fonction du débit (PCR) de la connexion sur laquelle sont transmises les cellules, le débit étant évalué à partir des informations de débit crête négociées avec le système pour la connexion. A l'arrivée de la première cellule d'un paquet, on compare le débit évalué des cellules du paquet et du débit disponible (RTC) sur le noeud, qui est calculé comme la différence entre le débit possible du noeud et la somme des débits des connexions des paquets en cours de transmission par le noeud. On assure ainsi simplement un contrôle efficace des congestions, sans devoir transmettre des informations de gestion des ressources sur des cellules dédiées.

Filed: 1998-10-22
Abstract: The present invention pertains to the field of jet-generation techniques. A gas-liquid mixture is fed from a jet apparatus into a jet converter where the flow of said gas-liquid mixture is first converted by its expansion into a supersonic liquid-gas flow. This supersonic liquid-gas flow is then slowed down in a profiled flow section of the converter for generating a pressure jump and for partially converting the kinetic energy of the flow into pressure energy. In order to implement this operation process, the apparatus includes a jet converter for the flow which comprises an expansion chamber as well as a profiled flow section. The inlet of the expansion chamber is connected to the outlet of the jet apparatus while the outlet of the profiled flow section is connected to a separator.

Filed: 2000-06-14
Abstract: A method for aiding in the detection of prostate cancer in male human patients, e.g., for differentiating prostate cancer from the normal condition and from benign prostate diseases such as prostate hypertrophy (BPH) and prostatitis, by a reflex method in which complexed prostate specific antigen (cPSA) is first measured in a blood sample from a male patient, and if the patient's cPSA blood level is greater than an upper limit of normal (e.g., between about 2 and about 4 ng/mL), total PSA  (tPSA) is then measured in the sample and the proportion of the measured tPSA amount that is the measured cPSA amount is determined. The cut-off for the proportion of cPSA  to tPSA can be set to provide an indication that the patient is not at risk for prostate cancer (e.g., less than about 82%), or to provide an indication that the patient is at risk for prostate cancer (e.g., greater than about 83 %). This c + c/t reflex method has been found to provide an improved method for the detection of prostate cancer, eliminating the need for a significant number of patients to undergo unnecessary prostate biopsy.
