Patent CA-2328713-A1 (CA)
Inventor: HILL EDWARD A
IPC: G02B6/35
Filed: 2000-12-15
Abstract: A microelectromechanical structure capable of switching optical signals from an input fiber to one of two or more output fibers. In one embodiment, the MEMS  optical cross-connect switch comprises a first microelectronic substrate having a pop-up mirror disposed on the surface of the substrate and a rotational magnetic field source, such as a variably controlled magnetic field source. The rotational magnetic field source allows for reliable actuation of the pop-up mirror from a non-reflective state to a reflective state. Additionally the invention is embodied in a MEMS optical cross-connect switch having a first microelectronic substrate having a pop-up mirror disposed on the surface of the substrate and a positioning structure disposed in a fixed positional relationship relative to the first substrate. The positioning structure may comprise a positioning structure extending from a second microelectronic substrate that is in a fixed positional relationship relative to the first microelectronic substrate. The positioning structure serves to restrict further movement of the pop-up mirror when the pop-up mirror has been actuated into a reflective state. Additionally, the positioning structure may be electrostatically activated through a voltage source connected to the second substrate such that electrostatic activation of the positioning structure causes the pop-up mirror to be "locked" in the reflective state. The invention is also embodied in an optical cross-connect switch array of multiple pop-up mirrors and positioning structures.  Additionally, the invention is embodied in an optical cross-connect switch system having one or more optical fiber inputs and two or more optical fiber outputs. Methods for conducting optical cross-connect switching and fabrication methods are also provided.

Title: Procede et appareil de demasquage d'images
Inventor: KARIDI RON D
IPC: H04N1/52
Filed: 1999-07-01
Abstract: L'invention concerne un procédé de démasquage d'images. Ce procédé consiste tout d'abord à lisser l'image en appliquant une convolution avec un noyau à filtre passe-bas qui est un paramètre de la fonction de démasquage. A l'aide de l'image lissée, on effectue une détermination pour chaque pixel, pour les pixels autour de cette dernière qui participent au filtre modifié. Pour un pixel en cours, une fenêtre est considérée avec la taille du noyau à filtre passe-bas, le pixel en cours se situant au centre de cette fenêtre. Un seuil T1 qui est donné comme paramètre est utilisé pour marquer les pixels dans la fenêtre en cours. Si l'on considère un pixel dans la fenêtre, si pour tous les composants de couleur la différence entre cette valeur de pixel par rapport à la valeur du pixel central est inférieure à T1 en valeur absolue, le pixel est marqué avec a 1. Sinon, le pixel est marqué avec un 0. Enfin, une version adaptative du filtre passe-bas est appliquée. Si le nombre de pixels marqués avec un 1 dans la fenêtre est inférieur à un tiers de la taille du noyau, la valeur du pixel d'origine est rétablie. En outre, pour un composant de couleur pour lequel on constate un faible changement de valeurs dans la fenêtre d'origine (non lissée) (c'est-à-dire, la différence entre la valeur maximale et la valeur minimale dans ce composant est inférieure à un autre seuil T2), la valeur de ce composant de couleur est rétablie. Si ces conditions ne se maintiennent pas, une nouvelle valeur est déterminée pour chaque composant. Pour constituer la fenêtre d'origine, le noyau à filtre passe-bas est masqué avec les marquages 0/1 à partir de la deuxième étape. C'est-à-dire, la convolution modifiée utilise un noyau adaptif qui est identique au noyau à filtre passe-bas dans les emplacements marqués avec un, mais comporte zéro entrées dans les emplacements marqués avec zéro.

Title: Multilevel coding with unequal error protection and time diversity for bandwidth efficient transmission
Inventor: CHUNG SAE-YOUNG
IPC: H03M13/05
Filed: 2001-02-20
Abstract: Improved techniques for multilevel coding of a stream of information bits in a communication system are disclosed. The stream of information bits is separated into portions, and each of the portions is associated with a different level of the multilevel coding. At least one code is applied to the portion of the information bits of each level in a designated subset of the full set of levels, such that the portions of the information bits for levels in the designated subset are coded while the portions of the information bits for levels not in the designated subset are uncoded. Both the coded portions of the information bits and the uncoded portions of the information bits are used to select modulation symbols for transmission in the system. Advantageously, the invention provides improved coding gain relative to conventional techniques, and can be configured to provide unequal error protection as well as time diversity for transmissions in the system.
