Title: Procede et dispositif d'utilisation de l'energie transmise par la totalite du spectre dans un systeme de communication a etalement du spectre pour poursuivre l'energie et le temps de phase de destinataires individuels
Inventor: ZEHAVI EPHRAIM
IPC: H04B1/7085
Filed: 1996-01-03
Abstract: La présente invention concerne un procédé et un dispositif de poursuite de la fréquence et de la phase de signaux de systèmes de communication à étalement du spectre, permettant d'utiliser plus efficacement les informations disponibles concernant la fréquence et la phase de la porteuse, et consistant à utiliser la majeure partie ou la totalité de l'énergie occupant le spectre des fréquences d'un signal de porteuse reçu, y compris l'énergie provenant de signaux de communication produits à l'intention d'autres utilisateurs du système. Des signaux multiples de communication à étalement du spectre (182) sont fournis en parallèle en entrée des récepteurs de données (126A' - 126N') qui resserrent le spectre au moyen de codes de resserrement présélectionnés caractérisés par un angle de phase, et qui décodent en utilisant des codes orthogonaux multiples actifs dans le cadre du système de communication. Les signaux multiples décodés sont ensuite combinés (188) de façon à former un seul signal de détection de phase qui est repris par au moins une boucle de poursuite (184) pour la poursuite de la fréquence et de la phase du signal de porteuse correspondant aux signaux de communication reçus. La boucle de poursuite (184) génère un signal de synchronisation qui sert à caler l'angle de phase (186) utilisé pour le resserrement. Dans d'autres modes de réalisation, les signaux de communication sont resserrés au moyen des codes de pseudo bruit appropriés, puis séparés en canaux en phase (I) et en canaux en quadrature (Q) (214) où les symboles de données sont traités par des transformateurs de Hadamard rapides (218, 220) pour générer les bits de données correspondants. Les données sont constituées en couples de produits entre les canaux (224), et additionnées à des codes multiples ou à la totalité des codes orthogonaux (226) d'abonnés actifs. Cette somme, caractéristique du niveau de différence entre la phase estimée et la phase réelle des signaux de communication reçus, sert à caler la phase d'application destinée aux codes de pseudo bruit (230).

Abstract: The invention provides a method of assessment of carbohydrate-deficient transferrin in a transferrin containing body fluid, said method comprising the steps of: i) obtaining a transferrin containing liquid sample of or derived from a said fluid; ii) contacting said sample with a source of iron ions; iii) subsequently contacting said sample with an anionic ion exchange resin at a pH such as to cause carbohydrate-deficient transferrin to be retained by said resin; iv) subsequently contacting said resin with an eluant serving to release carbohydrate-deficient transferrin into the eluate from said resin; v) collecting a volume of said eluate substantially free from tetra- and pentasialo transferrin; and vi) assessing the transferrin variant content in said volume of eluate. By including at least a proportion of the trisialotransferrin in the eluate, it is possible to use relatively simple assessment techniques such as turbidimetry in the assay.

Patent CA-2240135-A1 (CA)
Inventor: ATTREE STEPHEN M
IPC: C12N5/02
Filed: 1998-06-05
Abstract: The invention comprises methods for producing mature desiccated and desiccation-tolerant somatic embryos, particularly conifer embryos. The methods include the application of a growth-promoting hormone such as abscisic acid (ABA) to the immature embryos during development.      The embryos are also water stressed during development.      The concentration of the ABA undergoes a net increase relative to its initial concentration to reach a peak prior to discontinuing ABA treatment when the embryos have attained a moisture content of between 32 and 55%. The water stressing may remain constant or may undergo a net increase in intensity over the period of time during which it is applied to the embryos. The method may optionally include the further water stressing of the mature embryos to further reduce moisture contents of the embryos preferably to the level at which the embryos are tolerant of freezer storage.

A groove (12a, 12b, 22a, 22b) is provided in each of mutually opposing side faces along a turbine axial direction of mutually adjacent shrouds (11a, 11b, 21a, 21b) in the turbine circumferential direction and a seal plate (1) of thin plate shape is disposed with its each bent portion (1a, 1b) being inserted into the groove. The bent portion has a width which is slightly larger than that of the groove and is flexibly deformable to be inserted into the groove. The bent portion, being pressed down and inserted into the groove, is fixed in the groove by a spring effect. The seal plate partitions a gas flow passage (40) and a cooling air introducing passage on a turbine casing side of the outer shrouds (11a, 11b).      There is caused no gap between the groove and the seal plate due to thermal deformation of the shrouds and sealing ability can be enhanced.

IPC: G01M17/007

Abstract: In the method and the apparatus for the examination of shock absorbers installed on a vehicle, a vibratory platform, on which  one  wheel  of  the vehicle  is  stood  and which may be reciprocated with a suitable amplitude and variable frequency in a vertical, is employed to subject the wheel to an oscillation. The damping of the shock absorber is checked from the force response of the running gear to the oscillations of the vibratory platform and the relative phase function between the force exerted by  the  vibratory platform  and  the  motion  of  the  vibratory platform. The data signal, which represents the variations with time of the force response at a target frequency, is split by a tension-compression stage means into a compression stage signal, which is characteristic for the compression stage of the shock absorber, and a tension stage signal, which is characteristic for the tension stage of the shock absorber. The compression stage signal and the tension stage signal are separately supplied to further preparing means. As a basis of assessment for the quality of the installed shock absorber the degree of axle damping as related to the quotient of the spring-suspended mass to the non-spring-suspended mass is calculated. The measured values of the degree of axle damping are related to a characteristic line of a critical or border value degree of axle damping, which delimits the range of non-acceptable degrees of axle damping.
