Title: Seringue auto-destructible
Inventor: CAMPBELL DOUGLAS C V
IPC: A61M5/50
Filed: 2000-09-21
Abstract: L'invention concerne une seringue pourvue d'une structure déformante (50) destinée à déformer de façon permanente la paroi (12) du cylindre et rompre le joint (30) d'étanchéité entre le piston (20) et la paroi du cylindre. Cette structure déformante est montée pivotante dans le piston, de manière à passer par rotation d'une position de repos où la structure déformante ne déforme pas la paroi du cylindre à une position d'activation où le dispositif de déformation vient au contact de la paroi du cylindre de manière à déformer cette dernière de façon permanente, et vice-versa. Le piston est équipé d'un actionneur destiné à faire tourner la structure déformante pour la faire passer en position de contact avec la paroi du corps de pompe lorsque le piston revient en arrière, à la suite d'une injection complète ou partielle. Ce mécanisme fait de la seringue une seringue à usage unique, que l'on ne peut pas ré-utiliser après la première injection, ce qui empêche tout re-remplissage éventuel de ladite seringue.

Title: Convertisseurs elevateurs et abaisseurs de frequence de rejet d'image/suppression de porteuse pseudo-bruit
Inventor: WIGHT JAMES STUART
IPC: H04B1/707
Filed: 2002-10-04
Abstract: L'invention concerne un convertisseur élévateur de fréquence de suppression de porteuse pseudo-bruit (PN) ainsi que des circuits de convertisseur abaisseur de fréquence et de convertisseur élévateur de fréquence de rejet de bande latérale d'image pseudo-bruit. Les circuits de rejet de bande latérale permettent de recourir à la conversion d'élévation de fréquence en une étape sans faire intervenir des filtres Q élevé associés aux architectures de conversion d'élévation en deux étapes. Pour la suppression de porteuse, le spectre de fréquences d'un signal d'entrée subit un étalement PSK (BPSK ou QPSK) par un signal PN et le signal ainsi étalé est élevé en fréquence par une porteuse modulée (oscillateur local) PSK (BPSK ou QPSK), ayant subit la modulation par la même séquence PN. Dans un convertisseur élévateur de fréquence, une porteuse subit une modulation QPSK par les séquences PN indépendantes, le spectre de fréquences du signal d'entrée subissant un étalement QPSK par les mêmes séquences PN indépendantes ; les résultats de rejet de bande latérale d'image étant obtenus suite à la conversion d'élévation du signal d'étalement QPSK dans un mélangeur via la porteuse à modulation QPSK. Dans un convertisseur abaisseur, un signal de porteuse ayant subi une modulation QPSK par des séquences PN indépendantes est utilisé pour abaisser en fréquence un signal d'entrée dans un mélangeur, le signal abaissé en fréquence obtenu subissant un étalement QPSK par les mêmes séquences PN indépendantes. La bande latérale d'image est ainsi rejetée.

Title: Decoder for subsampled video signal
Inventor: MASUMOTO TAKAHIKO
IPC: H04N7/015
Filed: 1990-02-02
Abstract: ABSTRACT OF THE DISCLOSURE    Disclosed is a MUSE decoder for a pixel signal sampled in accordance with Multiple Sub-nyquist Sampling Encoding (MUSE).  An interframe interpolation circuit (142) applies a pixel signal Sg which is not subjected to noise reduction processing to an intrafield interpolation circuit (18') for motion picture processing through a signal line (L5).  A pixel signal delayed, which is outputted from delay circuits (24a, 24b) is subjected to a required noise reduction processing by an adder 60. Since the intrafield interpolation circuit 18' receives the pixel signal Sg which is not subjected to the noise reduction processing, an adverse influence on a motion picture, which may be caused by the noise reduction, is prevented even in case that the delay circuits (24a, 24b) are shared for motion picture processing and still picture processing.

Patent CA-2012303-A1 (CA)
IPC: F16H7/08
Filed: 1990-03-15
Abstract: ABSTRACT OF THE DISCLOSURE         A tensioning device is provided for a flexible belt wound around the pulleys of a drive mechanism.  The tensioning device includes an elastic biasing element and a damping mechanism.  The biasing element applies a force on the belt in a predetermined direction to oppose belt slackenings.  The damping mechanism dampens movements of the belt.  The biasing element and the damping mechanism constitute a single unit wherein both exert on the belt forces which act on the belt at the same time in a predetermined direction to maintain a predetermined tensioning.  The biasing element acts independently of the damping mechanism in the presence of considerable slackenings of the belt and functions as part of the damping mechanism to dampen thrusts of the belt acting on the device in the direction opposite to the predetermined direction.  A connection unit connects the damping mechanism to the biasing element.  This connection unit is an elastic system which applies a reaction force according to the predetermined direction in which the biasing element acts on the belt.

Title: Design for an actuator arm for a disc drive
Inventor: GHOSE SANJOY
IPC: G11B5/48
Filed: 1990-05-01
Abstract: ABSTRACT OF THE DISCLOSURE      A pivot bearing assembly for a disc drive  comprising in  combination  a  bearing surrounded on one  side by a wishbone-shaped end of the actuator arm, and on the other side by a biasing spring metal strip whose ends are tightly attached to the split ends of the wishbone of the actuator arm.  When the arm assembly is mounted in the disc drive, the bearing is mounted on its center of rotation, with the spring tensile force biasing the head of the actuator arm against the spindle of the stepper motor.  By providing the distal end of the actuator arm with a gear sector having gear teeth on its face which mesh with a pinion on the motor shaft of the stepper motor, rotation of the motor shaft across the face of the gear sector causes movement of the actuator arm and with it the flexure and transducer across the surface of the disc.   The head arm supporting the flexure and transducer extends from the side of the actuator drive arm at a point near the stepper motor driven end of the drive arm, reducing head arm length.

Patent CA-2020645-A1 (CA)
IPC: G01S13/90
Filed: 1990-07-06
Abstract: For the  imaging        of terrains with varied ground reflectivity,  azimuth spectra continuously following each other in time are formed over a set period of time in a method for extracting motion errors of a platform carrying a coherent imaging radar system from raw radar data.  By determining the position of the maximum of the correlation between two azimuth spectra formed immediately following each other in time, the frequency shift of the ground  reflectivity part  is obtained.  Then a separation of a velocity Vv(t) in  the forward direction from an acceleration ?b(t) in the direction of LOS     of the antenna is performed by filtering and the acceleration ?b(t) obtained is subjected to normalization   after two-fold integration, by means of which the displacement in LOS, i.e. the motion errors in the line of sight direction of the antenna, is obtained.  In contrast to GPS systems, all information is taken from the raw radar data and no ground station is required, so that the present method can be used much more flexibly and is more self-sufficient.   Furthermore, in comparison with the autofocus method, the present method has a much greater band width and can be performed in real time, which cannot be realized with the autofocus method.
