Patent EP-0653121-A1 (EP)
Title: Digital audio synchroniser.
Inventor: TRAVIS CHRISTOPHER JULIAN
IPC: H03H17/02
Filed: 1993-07-29
Abstract: A digital audio synchroniser includes one or a pair of buffer stores (12, 16) in series with a digital interpolating filter (14). A control circuit (18) detects when there is a "slip" between input and output, requiring loss or addition of a sample, and the filter executes a delay adjustment cycle in response thereto. The filter (14) takes the form of a substantially all-pass infinite-impulse-response filter of recursive form using feedback (Figures 4, 5, 6 or 7) which is found to give subjectively good performance although it introduces a frequency-dependent group delay, is also easy to implement, and has low overall delay.

Abstract: The invention provides a vertical-to-surface transmission electro-photonic semiconductor device with a mesa structure of light reflective multiple layers in which the device includes a high resistive region for a carrier confinement. The high resistive region (12) is formed by an ion-implantation of proton (11) in a downward oblique direction during a rotation of a semiconductor substrate with use of a photo-resist mask (19) whose horizontal width is larger than that of the mesa structure (10). The high resistive region (12) defines a light emitting area of an active layer (4), an inverse circular truncated cone like definition of a top cladding region (5) and a circular truncated cone like definition of a bottom cladding region (3). The oblique angle ion-implantation permits the top cladding region to be free from any exposure of the ion-implantation thereby an electrical resistance of the device is reduced.

Abstract: Un multiprocesseur à pipelines multiples est constitué d'un matériel de communication et d'algorithmes de communication parallèles exempts de contention mais également optimaux, le temps de communication étant minimisé pour toute tâche de calcul vectoriel. Cet appareil utilise un réseau d'interconnexion de processeurs hypercubiques capable de transmettre sur tous les fils simultanément. Un ensemble d'algorithmes d'acheminement pour toute tâche de communication est calculé ou stocké dans une mémoire pour commander la communication interprocesseur. Chaque tâche de calcul est définie comme une pluralité de sous-tâches définissant chacune une interconnexion en hypercube particulière de processeurs. L'exécution de la pluralité de sous-tâches sur le réseau d'interconnexion en hypercube met en ÷uvre la tâche de calcul. La sélection de la pluralité de tâches d'une manière qui interconnecte sans blocage les processeurs réduit également le temps de communication, l'activation des interconnexions en hypercube étant accomplie rapidement étant donné qu'aucun réglage de commutateur de point de croisement ne doit être calculé.

Abstract: Un circuit servant à surveiller et à réguler des paramètres d'un ensemble électrochirurgical (10), ESU, relatifs à la charge et à l'énergie de radiofréquence, comporte un circuit de détection de sortie sensible à la charge (11) mesurant la charge de l'ESU. Un modificateur de signal (12) couplé au circuit de détection (11) emplifie les signaux mesurés et les transmet à un tampon (13). Un convertisseur analogique/numérique (18), A/N, numérise les signaux et échantillonne le train d'impulsions d'ondes à une fréquence d'environ 8 millions d'échantillons à la seconde. Une mémoire de données (21) mémorise les signaux numérisés. Une horloge de commande de radiofréquence (27) est reliée à la sortie de l'ESU; une horloge d'échantillonnage (19) utilise un décalage de phase afin d'interroger les signaux d'entrée vers un processeur (20), DSP, à une fréquence d'échantillonnage plus grande qu'elle ne le serait sans ledit décalage. Le DSP reçoit les signaux mémorisés depuis la mémoire de données (21) et les traite pendant la surveillance et le calcul des paramètres de l'ESU mesurés, à savoir la tension, le courant, la puissance, l'impédance de charge, le courant de fuite, la tension crête à crête, le courant crête à crête, la teneur spectrale et/ou le facteur de crête de l'énergie du train d'impulsions d'ondes de radiofréquence à utiliser en tant que rétroaction de régulation soit pour l'alimentation en haute tension dans l'ESU soit pour la régulation des impulsions de commande de radiofréquence ou bien pour les deux. Un procédé surveille et régule l'ESU par rapport à la charge et comprend les étapes suivantes: recueil des paramètres par le circuit de détection de sortie de l'ESU (11) sensible aux charges; amplification des signaux par le modificateur de signaux (12); transmission des signaux vers le tampon (13); conversion des signaux par le convertisseur analogique/numérique (18); mémorisation des signaux dans la mémoire de données (21); de réception des signaux dans le DSP, ainsi que le traitement, la surveillance et la régulation des signaux par mesure répétée des paramètres de sortie de l'ESU.

Abstract: Un faisceau optique à modulation HF élevée est produit à la sortie (10) en générant dans la source (4a) une modulation à basse fréquence utilisée pour commander la sortie optique (9) d'un laser (1) puis en modulant ladite sortie optique (3) dans un modulateur optique (6) à l'aide d'un signal de commande présentant une modulation à basse fréquence différente générée par la source (4b). L'une et/ou l'autre des deux modulations à basse fréquence est/sont  également porteuse(s) d'une information modulée. L'effet du modulateur optique (6) est de transposer la modulation du faisceau optique par la fréquence de modulation du signal de commande. Le modulateur optique (6) peut consister en un interféromètre de Mach-Zehnder. La non-linéarité d'un tel modulateur par rapport à son signal de commande d'entrée peut être exploitée en sélectionnant l'amplitude du signal de commande de façon telle que la sortie optique (3) soit transposée d'un entier multiple de la fréquence de modulation générée par la source (4b). Ces méthodes évitent de devoir appliquer la modulation à haute fréquence à l'entrée du laser (2) et/ou directement à l'entrée de commande (7).

Abstract: To condition data, especially voice signal parameters, for transmission at a low bit rate, like signal parameters are combined in sections in quantized form. To achieve further bit reduction, bits are suppressed from the total number of bits of at least two sections, such that the suppression bit differential from the total number of unreduced bits is formed to the next higher power of two. This procedure provides a better voice quality than when the number of quantization steps is changed by multiples of two.
