Title: Systeme et procede de syncrhonisation temps et frequence d'un systeme de radiocommunications
Inventor: DENT PAUL W
IPC: H04B7/26

Granted: 2005-03-15
Abstract: La présente invention concerne une station de radiocommunications telle qu'un téléphone portable identifiant rapidement un signal de porteuse désiré ou un créneau de temps de signal de porteuse et se synchronisant en temps et fréquence sur cette porteuse ou ce créneau. La synchronisation se réalise même lorsque des signaux de référence temps ou fréquence de la station de communication sont décalés, par exemple, en raison d'une dérive par rapport au signal de porteuse ou au créneau de temps par moyennage de successions de mesures de signaux qui surviennent au moment où on attend les valeurs de signaux correspondants. Selon l'un des procédés, on fait plusieurs mesures du signal reçu pris dans un groupe de points temporels prédéterminés dans lequel les valeurs attendues sont moyennées ensemble de façon à améliorer le rapport signal/bruit. On effectue plusieurs fois le moyennage au moyen de différents groupes de points temporels, lesdits groupes correspondant chacun aux erreurs de fréquence d'horloge différentes attendues. Les résultats des moyennages servent à déterminer la meilleure hypothèse de signal reçu. Une programmation dynamique permet ensuite de tester les hypothèses de synchronisation à partir de différentes hypothèses de pente de dérive temporelle, ce qui permet d'établir une distinction entre différentes hypothèses de temps et une pente de dérive temporelle de façon à maximiser les sommes de corrélations.

Abstract: L'invention concerne un procédé et un appareil permettant de calculer la masse d'une composition d'un volume de fluide ou le rendement d'échange de cette composition avec un fluide d'échange, notamment l'urée dans l'organisme d'un patient dialysé. Les calculs sont basés sur une masse totale d'urée dans l'organisme. On calcule la concentration d'urée Cd dans le dialysat effluent. Ensuite, on calcule la masse d'urée U totalement extraite en intégrant le produit de la concentration d'urée Cd et du débit du dialysat Qd. On détermine le rendement relatif momentané de l'extraction (K/V) essentiellement en calculant la pente du logarithme de la courbe de concentration, puis en déterminant la masse momentanée à partir de ce résultat. Cela permet de déterminer avec une grande précision la masse d'urée dans l'organisme avant traitement. En outre, on détermine l'efficacité relative momentanée en un point quelconque à l'aide de l'urée U extraite. Enfin, on calcule la dose de dialyse par l'intégration des rendements momentanés.

Granted: 2007-04-10
Abstract: A system for converting an electrical signal to an optical signal for a fiber optic system sensor includes a sensor that produces an electrical signal based upon a parameter being measured. A material that changes dimensions is responsive to an applied electrical signal.      The electrical signal is produced by the sensor connected across the material. An optical fiber is coupled to the material such that dimension changes of the material produce strain in the optical fiber. The produced strain is operable to affect light traveling through the optical fiber to produce an optical signal for a fiber optic system. The optical fiber is part of an optical interferometer and strain produced in the optical fiber creates a phase change in the interferometer.

Title: Derailleur bicycle; retractable chain strain mechanical sensor to control an electric booster
Inventor: ROUTIER THIERRY
IPC: B62M6/40
Filed: 2000-06-21
Granted: 2002-02-05
Abstract: One of the major barriers to the daily use of a bicycle for work/home commuting purposes has always been steep climbs. An innovative chain strain sensing device that controls an interface to allow installation of a wide selection of existing cordless power tools into a derailleur bicycle power train is proposed here.  The chain tension applied by the rider is sensed by a mechanical device that has the capability of following all chain lateral positions that are imposed by the rear (or front) derailleur shifter. The tension signal is then directly sent to the power tool trigger through a control cable. The result is that the power tool motor is activated only when extra power is required by the rider. Unlike all other existing electric bike boosters having a throttle controlled manually, the main benefit of this concept is to maximize the autonomy of the motor batteries as boost is provided only when the rider pedals. The complete system is so light weight (under 12 lb) and so compact that the rider can still enjoy the regular behavior (including the gear shifting capability) and feeling of the bicycle when riding on shallow rates, flat road portions or downhill.

Abstract: The present invention provides a connector for terminating an optical fiber.  The connector comprises a one-piece housing, a ferrule assembly and an insert. The insert has keys formed thereon that are adapted to mate with keyways formed in the housing. The housing has a first opening formed therein that first receives the ferrule assembly and then the insert and a second opening opposite the first opening. The end of the ferrule assembly that holds the end of the optical fiber protrudes through the second opening. The insert has a flange thereon that has two oppositely located flat surfaces and two oppositely located keys. The keys each have a chamfered surface. The keys and the flat surfaces of the flange provide the flange with a substantially rectangular cross-section. The first opening formed in the housing has a substantially square cross-section. When the insert is inserted into the first end of the housing, the substantially square cross-section of the opening aligns with the oppositely located flat surfaces of the flange to thereby cause the keys of the flange to align with the keyways formed in the surfaces of the housing. The chamfered surfaces of the keys deflect the sides of the housing outwardly as the insert is inserted into the housing. The keys of the insert are then received by the keyways formed in the housing to lock the insert into place within the housing.
