Inventor: FREEBURG THOMAS A
IPC: H04L9/18
Filed: 1991-02-25
Abstract: Circuit de chiffrement dont le retard est sensiblement égal à zéro. On peut changer constamment l'algorithme de chiffrement à l'aide de codes et de polynômes programmables afin d'empêcher les éventuels correspondants récepteurs non voulus de décoder les données. On charge un code (101) et un polynôme (102) dans des registres. Le code est ensuite chargé dans un registre à décalage, puis il est décalé dans les portes OU exclusif (106) à une vitesse programmable. L'autre entrée des portes OU exclusif provient du résultat de l'intersection logique (103) d'un signal d'invalidation, du registre de polynôme (102) et du dernier étage du registre à décalage (104). On soumet huits bits des sorties du registre à décalage à une opération OU exclusif à l'aide des données d'entrée à chiffrer. La sortie de ces portes OU exclusif (105) représente les données chiffrées.

Abstract: Système de transmission d'informations utilisant des ondes électromagnétiques et comportant une première unité de communication (1) munie d'un premier émetteur et d'un premier récepteur, ainsi qu'une seconde unité de communication (5) munie d'un second récepteur et d'un second émetteur. La première unité de communication est montée sur un support immobile (2) et la second unité de communication (5) est montée sur un véhicule (3) roulant sur une piste (4). Les lobes d'antenne des émetteurs et des récepteurs sont conçus et orientés de manière à rendre possible une communication entre les première et seconde unités de communication lorsque le véhicule (3) est relativement peu éloigné du support (2) de la seconde unité. Ce système est principalement caractérisé en ce que le premier émetteur est configuré de sorte que son antenne émette une onde à polarisation rectiligne dont le vecteur de polarisation (vecteur E) dans le plan de polarisation forme un angle alpha avec la composante horizontale dans le plan de polarisation, alpha étant de préférence 45°. Les récepteurs et le second émetteur sont tous agecnés respectivement pour capteur et émettre une onde à polarisation correspondantes. Ainsi, on évite les réflexions gênantes dans les surfaces existantes essentiellement horizontales et verticales (8) du véhicule (3).

Abstract: An original image is divided into a plurality of image parts in the forms of image signals which are then given to liquid crystal light valves, respectively so that liquid crystal light valves display the plurality of image parts therein. These liquid crystal light valves allow light from light sources to pass through so as to form image light beams which are intensity-modulated in accordance with the divided image parts. A plurality of mirrors reflect the image light beams and introduce them onto a projecting lens system. In this arrangement, the plurality of mirrors are located in such a way that their reflecting surfaces do not cross the optical axis of the projecting lens system, and the image light beams are synthesized on the screen so as to reproduce an original image. Accordingly, the pixel density of the original image can be multiplied by a multiplier which equal to the number of used liquid crystal light valves.
