Patent EP-0321896-A1 (EP)
Inventor: LE MEHAUTE ALAIN
IPC: H03K3/78
Filed: 1988-12-19
Abstract: The time signal generated has a periodic configuration defined by an arrangement of precursor patterns resulting from a tree-like construction which implements, iteratively, laws for composing several patterns and consisting in defining the periodic configuration of the signal as a component "an" of the nth term Un with several components (an, bn) of a recurrent sequence defined at the level of each of its components by a particular recurrent law of composition, the initial term Uo having the precursor patterns (ao, bo) as components. The time signals known by the name fractal result from a tree-like construction of this type. The generator comprises a microprocessor (10) associated with a keyboard/display assembly (11), a read-only program memory (12), a random-access work memory (13) and a digital/analog output converter (14). Upon creation of a periodic signal-configuration pattern, its work memory contains at least three files; a file (An/Bn) of current patterns, a file (An-1 Bn-1) of preceding patterns and a file (Ao/Bo) of old patterns, the current patterns being constructed from arrangements of the old patterns in which the precursor patterns have been replaced by the preceding patterns.

Abstract: The coupling device 1 serves to connect a reservoir 3 to a machine, for instance for use in agriculture in the spraying of herbicides. In order to prevent personnel coming into contact with the concentrated herbicidal substance during changing of the reservoir the line 8, which draws the sub­stance out of the reservoir 3, can be retracted inside the coupling element 4 and the flexible casing 13 connecting thereto. Prior to changing of reservoir 3 the line 8 is en­tirely retracted into the coupling piece 4 and casing 13, thereby sealing with a suction nozzle 4 against the inner bore of coupling piece 4. Dripping liquid therefore remains contained by the coupling piece 4 and the casing 13.

Abstract: Ce récepteur optique comporte une photodiode (10) à polarisation inversée par une tension d'alimentation (14). Cette tension d'alimentation produit une tension à polarisation inversée déterminée par une unité de commande (16) et la photodiode est alignée sur la charge (22) par un circuit d'adaptation d'impédance (12). La photodiode présente de grandes variations de capacitance sur une gamme de tensions à polarisation inversée et peut être utilisée grâce à une barrière de Schottky ou à une photodiode P+N. En modifiant la tension de polarisation, la capacitance de la photodiode change pour modifier la fréquence syntonisée du récepteur. Le circuit d'adaptation annule la composante réactive de l'impédance de la photodiode et adapte la composante ohmique à la charge. La composante peut avoir un profil de concentration du dopant dans lequel une région intrinsèque ou légèrement dopée d'une largeur plus grande que la profondeur de pénétration moyenne des photons se trouve près de la jonction. Après la région intrinsèque, le profil de concentration du dopant peut être choisi de manière à obtenir une syntonisation linéaire. Ce profil donne une syntonisation linéaire sans que l'efficacité de la conversion par photodiode en souffre.

Filed: 1988-06-20
Abstract: Un processeur de trains d'impulsions (50) comprend une pluralité de modules discriminateurs d'impulsions (52, 54, 56) couplés en série à entrées parallèles, un module pour chaque impulsion consécutive d'une caractéristique d'un train d'impulsions d'une bande magnétique ou d'un signal cible d'une étiquette résonante produit dans une zone d'interrogation magnétique telle celles que l'on utilise dans des systèmes anti-vol dans des bibliothèques ou magasins de vêtement. Chaque module (52, 54, 56) est adapté aux caractéristiques particulières attendues de l'impulsion correspondante du train d'impulsions, les modules étant activés (78, 80) en série, déclencheant une alarme, uniquement si les caractéristiques attendues de la pluralité d'impulsions sont successivement présentes depuis l'impulsion initiale jusqu'à la dernière impulsion du train d'impulsions reçues. Les modules se ré-initialisent (72, 84, 86) automatiquement lorsque les caractéristiques de n'importe laquelle des impulsions sont différentes des caractéristiques attendues, de sorte que le processeur de trains d'impulsions est armé essentiellement en continu. Les modules sont sensibles à la séquence d'impulsions, à la polarité des impulsions, à la hauteur des impulsions, et aux durées minimale et maximale des différentes impulsions qui constituent un train d'impulsions, ce qui permet d'obtenir une détection extrêmement fiable.

Abstract: A medical irrigation device (10) for alternately introducing fluid into and withdrawing fluid from a body cavity through a conduit includes a container (12) defining a fluid-receiving volume and having an open neck (32), a filter (14) disposed within the container volume for separation of tissue particles above a predetermined size from fluid introduced from the container (12) into the body, and a cap for interconnecting the open neck (32) and conduit. In an improved irrigation device, the filter (14) consists of an elongated filter element (34) disposed adjacent the open neck (32) and extending within the volume of the container (12), the filter element (34) being disposed about an axis and defining a filter opening (26) axially aligned with and spaced from the open neck (32). Application of compressional forces upon the container (12) in directions transverse to the axis of the filter element (34) urges fluid toward and through the filter element (34) substantially free of tissue particles in excess of a predetermined size, to pass through the open neck (32) into the conduit toward the body cavity. Upon release of compressional forces, the container (12) expands to withdraw unfiltered tissue-particle-bearing fluid into the container (12) via the open neck (32) and generally axially within the filter element (34) through the filter opening (26).

Abstract: An electric power converter operably be means of a rotating or moving magnetic field having a substantially constant flux density or of a substantially constant magnitude. The electric power converter functions as a AC to DC, DC to AC or DC to DC converter, or as a phase changer/phase shifter or a voltage adjuster. A feature of the converter is the continuous supply of power from the primary phases in contrast to prior art converters in which only the phase having the highest voltage supplies power at any one time. Harmonic current distortion is, therefore, substantially reduced.
