Title: Liposomes contenant des matieres particulaires
Inventor: GURSEL IHSAN
IPC: A61K9/127
Filed: 1994-10-07
Granted: 2006-04-18
Abstract: L'invention se rapporte à un procédé de formation de liposomes, dont le diamètre est compris entre 0,1 µm et 50 µm, présentant une structure monolamellaire ou multilamellaire, et contenant des matières particulaires insolubles ou non dissoutes dans l'eau. Ce procédé consiste (a) à produire des liposomes et à retirer pratiquement la totalité de tout solvant organique utilisé dans leur préparation, (b) à lyophiliser les liposomes ainsi obtenus, puis (c) à les réhydrater en les mélangeant intimement à la matière particulaire. Les matières encapsulées préférées sont des matières particulaires, de préférence des micro-organismes, des cellules végétales ou animales, ou des structures insolubles dans l'eau ayant l'activité biochimique ou immunologique labile des solvants organiques, et n'importe quelle matière particulaire insoluble dans l'eau peut être encapsulée par ce procédé. Par exemple, des catalyseurs ou des médicaments qui sont modérément solubles peuvent également être incorporés de sorte que puisse s'effectuer une libération lente dans le corps d'un patient tout en évitant la libération de détersifs, compris dans les nombreux protocoles de préparation des liposomes.

Abstract: In an exhaust expansion chamber or tuned pipe of a two-cycle engine in a watercraft, variable amounts of water are injected, thus cooling the temperature within the expansion chamber and matching the sonic wave speed with that of the correct rpm of the motor.  Thus, by regulating the temperature of the exhaust gases in the tuned pipe with water, the efficiency of the two-cycle engine at varying revolutions per minute, is improved.

A second circuit (120) detects the  pick up of a local phone while the MODEM is off-hook by detecting a change in the impedance between the TIP and RING lines (106, 108). A third circuit (120) detects the hang up of a rem ote phone connected with the MODEM while the MODEM is off-hook by detecting a te mporary break in the DC loop between the central office and MODEM. A snoop circuit (130) monitors the telephone line for DTMF  signals while the MODEM is on-hook.

Title: A system for implanting an image into a video stream
Inventor: KREITMAN HAIM
IPC: G06T13/00
Filed: 1995-02-27
Granted: 2005-05-10
Abstract: A system and method which mixes images, such as an advertisement, with a video stream of action occurring within a relatively unchanging space, such as a playing field, is disclosed. The system utilizes a model of the background space to change the video stream so as to include the image at some location within the background space.  It includes a video frame grabber (10) and an image implantation system (14).  The frame grabber (10) grabs a single frame of the video signal at one time.  The image implantation system (14) typically implants the grabbed image into the frame onto a predefined portion of a preselected one of the surfaces of the background space if the portion is shown in the frame.

Abstract: Ingress noise in a hybrid fiber-coax transmission system (10) may be reduced by employing asymmetric taps (301'-308', 301"-308",) between a pair of line extenders (28-28) for attenuating downstream and upstream information by different weights. The downstream weights of the taps are selected to achieve a substantial constant power level at each tap for individual subscribers (14-14). The upstream attenuation of each tap is selected to allow for a nearly constant level of subscriber-generated information to be received at the line extender while the subscriber generated upstream information is supplied to the taps at a constant value that is maximized to reduce the effect of ingress noise.

Abstract: L'invention concerne un procédé de stabilisation de l'horizon de compas magnétiques. Des composantes spatiales du vecteur du champ géomagnétique et celles d'un vecteur d'accélération globale sont mesurées en des points de mesure. Le vecteur d'accélération globale correspond à la différence entre le vecteur d'accélération de la pesanteur et le vecteur d'accélération du compas magnétique. En considération des variations temporelles des composantes mesurées, la topologie de la position présente de l'horizon du compas magnétique est déterminée par rapport à celle de l'horizon stable. Des fonctions de qualité fournissent des informations sur l'écart de la nouvelle position spatiale par rapport à la précédente et permettent de mettre un procédé d'estimation en oeuvre, afin de déterminer si l'horizon stabilisé du système est exact. Ce procédé permet d'obtenir un horizon qui n'est pas exposé dans une large mesure aux accélérations du dispositif muni du compas magnétique, induites par le mouvement.
