Patent CA-2413219-A1 (CA)
Inventor: MATTSON GEOFFREY
IPC: H04L45/50
Filed: 2002-11-29
Abstract: A primary label switched path (LSP) defined in a label switching network has a protected portion for transmitting data packets containing a label stack from a first label switching node to a second label switching node, the protected portion including at least one Intermediate label switching node between the first and second nodes. To provide path recovery resources in case of link or node failure, it is proposed a method in which a backup LSP is defined from the first node to the second node. A transformation of the label stack of a packet transmitted along the protected portion of the primary LSP from an output of the first node to an input of the second node is determined. The first node is configured to switch a packet to the backup LSP upon detection of a failure in the protected portion of the primary LSP. In addition, a node of the backup LSP is configured to process the label stack of any packet transmitted along the backup LSP so as to apply the determined transformation.

Inventor: SAKURAI MASAAKI
IPC: G01N33/544
Filed: 2002-04-26
Abstract: A method of immunoassaying with the use of insoluble magnetic support particles which is appropriate for saving labor or treating a large number of specimens within a short time while avoiding problems in the stability of sensitized insoluble magnetic particles or difficulties in preparation. In assaying an antigenic substance in test samples, use is made of not insoluble magnetic support particles carrying an antibody specific to the antigenic substance but insoluble magnetic support particles in a state where the antibody, etc. are substantially not adsorbed. Then the antigenic substance to be assayed per se is adsorbed by the insoluble magnetic support particles and the adsorbed antigenic substance is reacted with a labeled antibody specific thereto. Thus, the antigenic substance in the test samples can be efficiently assayed in a mode suitable for automation.

Abstract: Methods and apparatus for antialiasing images that contain one or more image objects such as colored text, line art, and graphical objects, such that the edge pixels of an antialiased image object will exhibit relatively uniform values, and the appearance of the image object is thereby improved. In one embodiment, an improved antialiasing filter is employed to detect at least one region within the received image. Upon detecting a region containing a background image level that adjoins an image object having pixel values in a range other than a range of limit values, the antialiasing filter sets the pixel values of the edge or border pixels of the image object to substantially the same value. Selection among a logical filter operation and an averaging filter operation may be adaptively employed in the antialiasing filter in order to obtain the desired uniformity of pixel values.
