Patent CA-2456889-A1 (CA)
Inventor: JAMES ROBERT
IPC: G02B6/34
Filed: 2004-01-19
Abstract: A PLC device includes a planar lightwave circuit having optical layer deposited on a substrate, and a package base including a support for suspending the planar lightwave circuit above a portion of the package base. The substrate has a first coefficient of thermal expansion, whereas the package base has a second coefficient of thermal expansion. The first and second coefficients of thermal expansion differ such that a change in temperature causes the support to apply one of a compressive and a tensile force to the planar lightwave circuit in a plane within or parallel to the plane of the planar lightwave circuit. The induced stress affects the optical performance of the PLC device. For example, the induced stress may be used to reduce the temperature sensitivity of the device, and thus maintain device performance, or for providing efficient dynamic tuning of the device.

Title: Color filter patterns for image sensors
Inventor: HU XIAOPING
IPC: H04N9/04
Filed: 2004-03-10
Abstract: Color filter patterns are invented for coating an array of imaging sensing elements so to obtain color images. Each of the color filter patterns consists of a luminance color Y and two other complementary or non-overlapping colors tessellated in a Bayer pattern, hexagonal pattern, YUV422 pattern, or other ordered tessellation. In two preferred embodiments of the invention, the color filter pattern differs from a conventional Bayer Pattern or a conventional. hexagonal RGB pattern only in. that the G color is replaced by a luminance color Y but with varied pixel sizes. The color filter for luminance Y can be realized by a transparent coating or no coating at all. In addition, the effective sensing areas of different colors are so chosen that desired signal-to-noise ratios are obtained by adjusting flue color sensing areas and/or the sizes/curvatures of the micro lenses for the color pixels.

Patent CA-2491110-A1 (CA)
Inventor: JOHNSTON ANGUS
IPC: C12Q1/68
Filed: 2002-07-01
Abstract: Highly functionalized, porous organosilica particles and methods of their synthesis are described that employ high amounts of functional silane such as 3-mercaptopropyl trimethoxysilane. Silane particle diameters are controlled from less than 1 µm to over 100 µm. The particles have a high surface area due to their advantageous internal structures, which consist of large pores, typically up to 10 µm that are linked by small channels of typically about 20 nm diameter. Isothiocyanate modified fluorescent dyes can enter and react with thiol groups inside the pores. The invention also provides clear silica shells of controlled thicknesses to protect fluorescent signals and provide an independent parameter for distinguishing particle types based on light scattering off different sized particles. The particles are stable and useful for many purposes, particularly for optical bar coding in combinatorial synthesis of polymers such as nucleic acid, polypeptide, and other synthesized molecules.

Abstract: Système et procédé permettant de former des réseaux de zones de service de très grande échelle (MAN) grâce à la technologie de commutation Layer 2 (L2). Différents groupes de commutateurs L2 sont organisés logiquement en îles. A chaque île sont connectés une pluralité de sites clients, et une matrice d'interconnexion couple les îles entre elles. Les îles coopèrent afin de former une connexion Ethernet virtuelle (VEC) vers chaque ensemble de sites clients couplés. Les clients identifient leur trafic, qui correspond à une VEC, en le marquant ou en l'étiquetant à l'aide d'un identificateur VLAN d'équipement de client (CE-VLAN ID). Dans chaque île, le CE-VLAN ID spécifié par le trafic de client (et par conséquent le VEC correspondant) est mis en correspondance avec un VLAN ID unique d'équipement de fournisseur de MAN (PEVLAN ID). Pour éviter la formation de boucles, les îles exécutent le protocole de commande Inter-MAN (IMCP), qui constitue une version modifiée du protocole MSTP.
