The new digital telephone switching machine being put through their paces at Bell-Northern Research in Ottawa are disconcertingly silent and still ... their action is soundless and invisible: billions of electrons careening through the machines solid-state inwards, setting up and taking down speech paths, shunting signals to different lines and trunks, carrying countless maintenance and operational messages between processor, memories and switching matrix. 1, record 1, English, - digital%20telephone%20switching%20machine

Les nouveaux dispositifs de commutation téléphonique numérique expérimentés au Centre de recherches de la Bell Northern à Ottawa se révèlent incroyablement «sages» et silencieux [...] Insonores et invisibles, les activités réellement importantes sont en fait celles des milliards d’électrons qui dansent un ballet fantasmagorique parmi les circuits internes à semi-conducteurs, accordant ou non le passage aux conversations, dérivant les signaux vers les lignes principales et auxiliaires et transmettant d’innombrables messages relatifs au fonctionnement ou à la maintenance entre l'ordinateur, les mémoires et la matrice de commutation. 1, record 1, French, - dispositif%20de%20commutation%20t%C3%A9l%C3%A9phonique%20num%C3%A9rique

Les techniques d’imagerie par écho planar sont actuellement les plus rapides(quelques dizaines de millisecondes pour une image). Le principe consiste à réaliser le codage de l'ensemble du plan de Fourier(ligne de la matrice image) à la suite d’une seule [impulsion de radiofréquence] par commutation de gradients très puissants. 6, record 2, French, - imagerie%20par%20%C3%A9cho%20planar

La commutation à bord est une méthode [...] qui consiste à utiliser un seul répéteur à large bande par faisceau à desservir et une matrice de commutation cyclique [...] Celle-ci connecte tour à tour chaque faisceau de l'antenne de réception à chaque répéteur. Les stations émettent leurs informations sous forme de série de paquets cycliques, chaque paquet étant destiné à un faisceau particulier. La matrice de commutation aiguille chacun des paquets reçus vers le faisceau destinataire. À la réception, chaque station reçoit, regroupés en un multiplex temporel [dans le cas de l'AMRT], les paquets émis par les stations correspondantes situées dans les divers faisceaux. 2, record 3, French, - commutation%20%C3%A0%20bord
