Patent CA-2380043-A1 (CA)
Title: Variable dispersion compensator and optical transmission system
Inventor: KANIE TOMOHIKO
IPC: G02B5/10
Filed: 2002-04-02
Abstract: An optical signal, which is to become the subject of dispersion compensation, is split by optical combining/splitting unit 2, and each frequency component of the optical signal that is split is reflected by each reflective surface of reflective mirror 40 of reflective means 4 to apply a predetermined phase shift to the respective frequency components. Each reflected frequency component is then combined using optical combining/splitting unit 2, to give dispersion compensated optical signal. Furthermore, in regards to reflective means 4, which is used to apply phase shift to each frequency component of an optical signal, reflective mirror 40 is made a variable movable mirror by reflection position at each reflective surface, which reflects the frequency components, deforming the entire reflective surface. This allows dispersion that is created in an optical signal to be compensated with favorable controllability and high accuracy. As a result, it becomes possible to provide a variable dispersion compensator that presents high precision and controllability of dispersion compensation, and has a miniaturized optical circuit, and an optical transmission system comprising such variable dispersion compensator.

IPC: B32B7/06
Filed: 2000-07-26
Abstract: Cette invention concerne un procédé de fabrication d'une structure laminée qui consiste à : prendre un premier et d'un second substrat présentant chacun une première et une seconde surfaces séparées l'une de l'autre et opposées; mettre en contact au moins l'une des surfaces des substrats avec un matériau détachable de sorte qu'une partie de la première ou de la seconde surface des substrats soit recouverte par ledit matériau, alors que le reste de ladite première ou seconde surface n'en est pas recouverte; mettre en contact réciproque la première et la seconde surfaces du premier et du second substrat; et soumettre les substrats à des conditions telles que les parties des première et seconde surfaces des substrats recouvertes par le matériau détachable se collent l'une à l'autre pour former une structure laminée. La partie de la première ou de la seconde surface des substrats qui est recouverte par le matériau détachable permet aux premier et second substrats de se séparer l'un de l'autre, ce qui matérialise entre eux une ouverture coïncidant pour l'essentiel avec la partie recouverte du matériau détachable.

Abstract: A method and apparatus for providing an interactive mobile multimedia terminal (100). The mobile multimedia terminal (or MMT) (100) allows for wideband data stream reception using a digital data broadcast receiver (102) such as DVB-T.  Interactivity is realized with built-in local or large cell size communications link (116 and 112). The local link (112) could be WLAN or Bluetooth (a low-power RF transceiver). The large cell size communications link (116) could be a mobile station link e.g., GSM, CDMA, TDMA, etc. A mobile station with a Bluetooth link can be used as an IP router or a portable base station for large cell size communication if no local connection point is found. The MMT (100) integrates DVB-T reception, digital display, and communications links together to provide interactivity in a mobile environment. The MMT communications link with a mobile station enables it to act as an extended display for the mobile station.
