Title: Method and device for carrying out chemical reactions using a microlaminar mixer
Inventor: SCHUBERT KLAUS
IPC: B01J19/18
Filed: 1996-10-24
Abstract: Described is a method of carrying out a reaction between at least two reactants (A, B) each of which is divided by an array of slit-shaped microchannels (1a, 1b) into separate laminae of fluid which subsequently emerge into a common mixing and reaction chamber. The laminae of fluid have a thickness of < 1000 .mu.m, preferably < 100 .mu.m, and a width:thickness ratio of at least 10. The invention calls for the reactants (A, B) to be made to emerge into the mixing/reaction chamber as thin laminae of fluid (6a, 6b), each lamina (6a) of reactant A being fed into the mixing/reaction chamber in the immediate vicinity of a lamina (6b) of reactant B. The adjacent laminae (6a, 6b) subsequently mix in the chamber by diffusion and/or turbulence. The mixing process is thus accelerated significantly compared to conventional reactors. With rapid chemical reactions, this enables the formation of undesired side-products or further-reaction products to be avoided to a considerable extent.

Title: Optical protection switch employing an interference filter
Inventor: FISHMAN DANIEL A
IPC: H04L1/22
Filed: 1998-10-29
Abstract: A protection facility is provided for use in an optical communications node that communicates with another optical communications node via first and second bi-directional communications paths respectively serving as a service path and protection path, in which a filter filters signals respectivelyreceived over the service and protection paths and generates a main signal and a complementary signal for each of the paths. A control unit then generates a Loss of Signal (LOS_A) indication for the service path if a SUM signal or DIFF signal respectively derived as a function of a sum of the main and complementary signals generated for the service path and difference between the main and complementary signals generated for the service path is less than a respective threshold value. A switch then invokes protection switching responsive to the presence of the LOS_A indication.

Title: Optical power divider and fabrication method thereof
Inventor: RHEE TAE-HYUNG
IPC: G02B6/12
Filed: 1998-11-04
Abstract: An optical power divider using a beam separator and a beam expander, and a fabrication method therefor. The optical power divider includes an input optical waveguide having an input port for receiving incident light, for guiding the light incident via the input port, a plurality of output optical waveguides having at least two output ports, for outputting the light incident via the input optical waveguide to the output ports, wherein the number of output optical waveguides is equal to that of the output ports, and a beam separator located at a branch area in which the light incident on the input optical waveguide diverges toward the output opticalwaveguides, the beam separator being made of a material having a refractive index lower than the core of the input and output optical waveguides, for separating the light to the output optical waveguides with a predetermined ratio. Therefore, the length of the optical power divider becomes short and insertion loss can be lowered. Also, an optical power divider for the specific use, providing different splitting ratios between inner and outer output ports, can be easily designed by controlling the lengths of a side of each beam separator and beam expanders, and the splitting ratio of the output optical power of the optical power divider can be controlled. Also, the cost of fabricating the optical power divider can be reduced.

Filed: 1997-08-22
Abstract: A novel distributed synchronization system for use in each node of a distribute asynchronous telecommunications network system that continually monitors and controls the flow of data through an implementing node to prevent dataflow errors due to phase and frequency differences in source and destination nodal clocks, and to make the entire ring delay an integer number of frame packets to support the transmission of synchronous data. A synchronization data FIFO for storing predetermined fields or portions of fields of a unique frame packet received from a source node and to be transmitted to a destination node on the network. The frame packet includes a frame synchronization field indicating the beginning of a new frame packet; a payload field containing valid data; and a dead zone field providing bandwidth during which the present invention performs synchronization functions. A frame synchronization subsystem, implemented in a designated master node, guarantees that a frame is released at the beginning of an independently-determined frame regardless of ring latency. A word resynchronization subsystem manages the flow of data through the data FIFO of each non-master node, receiving and storing the data at the source node clock rate and transmitting the data according to its own clock, thereby guaranteeing the efficient receipt and transmission of data between asynchronously-communicating nodes.
