Title: Magneto-optical member
Inventor: KATO HIDEKI
IPC: G02B27/28
Filed: 2000-10-26
Abstract: The present invention. relates to a magneto-optical member with which a great magneto-optical effect can be obtained. A granular film 6 (granular magneto-optical thin film) is provided between an (SiO2/Ta2O5)n layer 4 and a (Ta2O5/SiO2)n layer 5 to form a magneto-optical member (one-dimensional photonic crystal) 1. The granular film 6 consists of magnetic minute particles made of Co 7 and a matrix 8 which is made of Sm2O3 (a rare earth-oxide) and which surrounds the magnetic minute particles. Co and Sm2O3 arc alternately sputtered at a low temperature by utilizing two target sputtering method to form the granular film 6. Thus, the granular film 6 is formed at a low temperature, and hence the disorder of the periodic structure of the (SiO2/Ta2O5)n layer 4 and the (Ta2O5/SiO2)n layer 5 which may be caused during heat treatment at a high temperature does not occur at all. As a result, the magneto-optical member is enabled to show an intense localization of light for the light having a specific wavelength, resulting in showing both a great magneto-optical effect and a high transmissivity.

Abstract: A method for routing connections in a connection-oriented communication network containing switching nodes (Ki) and transmission paths (Uij) between the nodes. Routing processors (RPi) are allocated to said nodes and an alternate route is determined by means of a routing algorithm in a routing system (RSY) according to the frequency of congestion in the transmission paths. ATM connection requests from subscribers are checked in the routing processors (RPi) against the controlled route. A negative decision is indicated when said route is not available for a specific connection request and an overflow message is sent to the routing system (RSY) containing the subscriber's relevant cell rate request and the current fill status of the transmission path. The alternate route is determined by taking into account the frequency of overflow messages for specific cell rate requests from other routes.

Title: A method and a system for coding rois
Inventor: LARSSON MATHIAS
IPC: H04N7/26
Filed: 1999-10-06
Abstract: In a method and a system for encoding and transmission of still images having at least one region of interest (ROI), the ROI coefficients of an image transformed into the frequency domain, preferably using a wavelet transform are encoded so that they are transmitted first and can be decoded by a receiver without transmission of the boundary of the ROI. In a preferred embodiment the coefficients belonging to the ROI are shifted so that the minimum ROI coefficient is larger than the largest background coefficient.  A receiver can then perform an opposite procedure and thereby obtain the ROI. By specifying how much the coefficients need to be shifted in order to avoid sending shape information several advantages are achieved.  Thus, it is possible to avoid sending shape information and to avoid shape encoding at encoder side. Furthermore, there is no need for a shape decoder at receiver side, and there is no need for the receiver to produce the ROI  mask. Also, in another preferred embodiment, the shifting (or scaling operations) required at encoder and decoder are also avoided.
