UWB IMPULSE GENERATOR MODULATED IN PHASE

L'invention concerne les générateurs d'impulsions à très large bande pour la communication radio en modulation de phase à des fréquences de plusieurs gigahertz. Le générateur comprend un oscillateur formé par une paire de branches différentielles croisées (T1, T'1) ayant deux sorties (S, S') reliées à une charge résonante LC. L'émission d'une impulsion UWB est provoquée par l'application d'un courant d'alimentation pendant quelques nanosecondes à la paire différentielle. Deux branches d'injection de courant sont reliées respectivement aux sorties S et S'. La commande de modulation de phase consiste à appliquer un courant d'injection (-Id) à une seule branche pour déséquilibrer la paire différentielle au début de la production de l'impulsion UWB. Selon le côté où est appliqué le courant d'injection, l'oscillation à la fréquence porteuse démarrera avec une phase ou une phase opposée. The invention relates to very broadband pulse generators for phase-modulated radio communication at frequencies of several gigahertz. The generator comprises an oscillator formed by a pair of crossed differential branches (T1, T'1) having two outputs (S, S ') connected to a resonant load LC. The emission of a UWB pulse is caused by the application of a supply current for a few nanoseconds to the differential pair. Two current injection branches are respectively connected to the outputs S and S '. The phase modulation control is to apply an injection current (-Id) to a single branch to unbalance the differential pair at the beginning of UWB pulse generation. Depending on the side where the injection current is applied, the oscillation at the carrier frequency will start with an opposite phase or phase.

Key (10) for a security cylinder comprising a handling element linked to an elongate key body having a rectilinear longitudinal axis, said key body being intended to be inserted into a key housing of said cylinder and being entirely comprised between, on the one hand, two parallel lateral planes and, on the other hand, two longitudinal edges situated between the two lateral planes, one of said edges forming the back (14) of the key body and the other edge being an active edge (15) intended to cooperate with the keying members of the securing cylinder, the back (14) and the active edge (15) being interconnected by a profile section comprising at the vicinity of the back (14) a longitudinal groove (11), with the free extremity area of the key body which is opposite to the handling element being at least partially oblique with respect to the longitudinal axis of the key body, the free extremity region of the key body comprising a first ramp (21) and a second ramp (22) which is offset with respect to the first ramp (21) in the insertion direction of the key (10) in the key housing of the cylinder, both ramps (21, 22) forming acute angles with the longitudinal axis of the key body.

Filtre coupe-bande avec intégrations fenêtrées successives, dispositif de filtrage passe-bande, système de détection de fréquence et procédé de traitement associés

Filtre coupe-bande avec intégrations fenêtrées successives, dispositif de filtrage passe-bande, système de détection de fréquence et procédé de traitement associés Ce filtre électronique coupe-bande (10) est apte à recevoir un signal d’entrée (Xe) et à délivrer un signal filtré (E) présentant, en une fréquence de coupure (Fc), une amplitude atténuée par rapport à celle du signal d’entrée (Xe). Il comprend un module (12) d’intégration du signal d’entrée lors de plusieurs fenêtres temporelles successives, chaque fenêtre temporelle débutant en un instant temporel initial respectif et ayant une durée sensiblement égale à l’inverse de la fréquence de coupure (Fc), les instants temporels initiaux d’au moins deux fenêtres distinctes étant séparés d’un décalage temporel de valeur supérieure ou égale à une durée prédéfinie de référence, chaque intégration du signal d’entrée (Xe) lors d’une fenêtre temporelle respective résultant en un signal intermédiaire (Si) respectif ; et un module (16) de sommation des signaux intermédiaires (Si) issus du module d’intégration (12) ; le signal filtré (E) étant fonction de la somme desdits signaux intermédiaires (Si).

Émetteur uwb compact à très basse consommation et forme d'onde reconfigurable

Very-low-consumption reconfigurable-waveform compact UWB emitter

A UWB pulse emitter includes an H-bridge having first and second branches in parallel, a first end common to the branches being connected to a first amplitude control module to regulate a high voltage, a second end common to the branches being connected to a second amplitude control module to regulate a low voltage. A first envelope control module controls the shape of the positive portion of a UWB pulse and a second envelope control module controls the shape of the negative portion of this pulse. Each branch comprises first and second switches for respectively switching the high voltage to a first or second input of the first envelope control module and the low voltage to a first or second output of the second envelope control module. Centre taps of the branches, between which the UWB antenna is connected, connect the outputs and the inputs of the control modules.
