Abstract: A semiconductor optical device having an optical waveguide (2a) which represents nonlinear refractive index change due to control light absorption. The waveguide (2a) has a bandgap wavelength that increases from its entrance (9) to its exit (10). In the case of the waveguide divided into first (4) to n-th regions, the bandgap wavelengths λ 1 , λ 2 , ..., λ n-1 , λ n  of the regions satisfy the relationship λ 1  < λ 2  < ...< λ n-1  < λ n . In the case of the waveguide not divided into regions, the bandgap wavelength λ of the waveguide monotonously increases from the entrance to the exit. This device can operate by the control light having a lower energy than the conventional one.

Abstract: A fiber optic switch (30) interconnects fiber optic channels (32) so that a fiber optic network can be implemented. Channel modules (34) provide ports (p1-pi) (33) for connection of the fiber optic channels (32). Each channel module (34) has a receive memory (84) for temporarily storing incoming data frames from the fiber optic channels (32) associated therewith. A switch module (36) having a data distribution network (42) interconnects each of the channel modules (34) and permits ultimate connection of a source channel (32) to a destination channel (32). A path allocation system (50), which controls the switch module (36), allocates the data paths between the channels (32). The path allocation system (30) has a scheduler (104) which maintains a destination queue (Q p1 -Q pi ) for each of the channels (32), a sentry (104) which determines when a new data frame (11) is ready to be routed, and an arbitrator (123) which arbitrates port availability and which grants transfer requests proposed by the scheduler (104). Significantly, the arbitrator (123) is equipped with fairness insurance mechanisms (130', 130'') for insuring that transfer requests are always timely and efficiently serviced.

The first-side plate 32 and second-side plate 33 are positioned relative to each other such that the dividers 35 of the second-side plate 33 are in line with the channels 11 of the first-side plate 32, and the dividers 34 of the first-side plate 32 are in line with the channels 17 of the second-side plate 33, thus preventing deformation of the seal plate 3 due to a high differential pressure between the coolants flowing through the channels of the first- and second-side plates. The corners of the first-side plate 32, second-side plate 33, and seal plate 3 are also shaped differently so that omission of one of the component plates can be easily confirmed.

Abstract: A multilayer reagent test strip measures the concentration of analyte in a liquid sample that is applied to it. The sample is guided to a number of assay areas arrayed along the strip, where the analyte can react with a reagent to cause a color change. Each assay area also includes an inhibitor for the color-change reaction. The inhibitor concentration increases in successive assay areas; thus, the number of areas that change color is a measure of the analyte concentration. The test strip is particularly adapted for measuring glucose in a whole blood sample. In a preferred embodiment, the sample is guided to the assay areas along a path formed by crushing selected areas of a membrane, and the assay areas are uncrushed areas of the membrane.

Abstract: The present invention relates to a computer-implemented method and apparatus for representing data. There is also disclosed a computerised method and apparatus for creation of a portion of an image (30) from the representation data of the image. The method of representing data involves dividing the data into a plurality of regions (6;32 to 35), wherein each region contains a first portion of said data; and then for each of said regions, performing the steps of: determining a mapping from a second portion (5) of said data to said first portion of the current region to minimise an error measure (ERROR MIN ), wherein said second portion of said data includes said current region so that said current region is positioned within said second portion of said data; storing said mapping as a representation of said current region if said error measure (ERROR MIN ) is below a predetermined threshold; and recursively applying the steps of said method to said current region if said error measure (ERROR MIN ) is greater than or equal to said predetermined tolerance. The computerised method for creation of a portion (112) of an image (110) from representation data of the image, comprises the steps of: selecting a region (112) of an arbitrary image corresponding to said portion of said image; determining subsample data (111) of the representation data, wherein upon decompression the subsample data includes at least said portion of said image so that said portion of said image is positioned within said subsample data; and decompressing said subsample data.

Abstract: Apparatus and method for learning current network behavior and predicting future behavior which utilizes a state transition graph. The graph includes nodes which represent network states, and arcs which represent trends in observable network parameters that result in a transition from a current state to another state. For example, a watch service may be instituted on multiple ports of a router, and the observed network traffic on the ports over time may be transformed into a state transition graph that represents network behavior. The network states may be labeled such as "good", or "bad", etc., according to a predetermined performance criteria. Once a state transition graph is constructed, the system may then monitor the current state and current trends of the network parameters in order to predict and display future network states. The system may include an automatic warning signal for alerting a user that the network is headed in the direction of a problematic state. The prediction of future network behavior may be made from the state transition graph, the current state of the network, and the current network trends.
