Title: Ribbon array optical switch and optical switch architecture utilizing same
Inventor: COHEN LEONARD GEORGE
IPC: H04B10/27
Filed: 1997-08-18
Abstract: A ribbon array switch in which an input ribbon array comprising a plurality of input optical fibers can be selectively switched to any one of a plurality of output ribbon arrays mounted on an outer periphery of a switch housing. Preferably, a stepper motor is used to rotate the input ribbon array along the outer periphery of the switch housing, the result being that the input optical fibers will be optically connected to corresponding output optical fibers that make up the output ribbon arrays. In another aspect, the invention features an optical switch architecture including a first stage comprising a fiber switch element and second stage comprising a ribbon array switch element described above. The output optical fibers of the fiber switch element make up the input ribbon array of the ribbon array switch element. The architecture switches an input optical fiber to any one of a plurality of output optical fibers by optically connecting the input optical fiber of the fiber switch element to a selected one of the output optical fibers of the fiber switch element and aligning the input ribbon array of the ribbon array switch element with a selected one of a plurality of output ribbon arrays of the ribbonarray switch element. Each of the output ribbon arrays comprises a predeterminednumber of output optical fibers. The result is that the output optical fibers of the fiber switch element will be optically connected to corresponding ones of the predetermined number of output optical fibers of the ribbon switch element, and thus the input optical fiber will be optically connected to a desired output optical fiber.

Title: Tone detection using discrete fourier transform techniques
Inventor: TONG WEN
IPC: H04B17/336
Filed: 1997-12-19
Abstract: Supervisory audio tone (SAT) in a receive signal in a wireless communications system is detected using a discrete Fourier transform (DFT) supplied with samples of a filtered and decimated signal derived from the receive signal. The DFT can comprise M 2-input butterfly computation stages for computing an N-point DFT where N =  2M. Each of the stages m from 1 to M-1 determines and stores, for each current sample at the input, at most 2m intermediate results forming only a subset of intermediate results required for computation by the next stage. Each of up to 2m other intermediate results required for computation by the next stage is produced by shifting of a respective stored intermediate result of the respective subset determined in respect of an input sample preceding the current sample by 2M-m-1 samples. For example there are M = 5 stages for a 32-point DFT having 18 outputs, 6 outputs for each of three SAT frequencies.

Filed: 1996-09-25
Abstract: A method and apparatus for providing an optimized page-based electronic document file (figure 2a) and downloading the optimized file. An optimized document file is created from a non-optimized electronic document (74). Page contents are contiguously written in the optimized file and page offset information (68, fig. 8a) used to locate individual pages and objects of the document. When downloading the optimized file from a host, the page offset information is read early and is used to download a specific page requested by the user without donwloading other pages in the document. A viewer may download (226) a first portion of the requested page, while all remaining portions of the requested page are located by a finder process using the page offset table (68, fig. 8a). Alternatively, all objects for a full page may be requested at once. The requested page can thus be downloaded with only one connection to the host. Optionally, shared objects can be downloaded and interleaved between portions of the page contents (284) that reference the shared objects. They can also be read in one transaction identifying byte ranges in the document. Subsequently, the requested page is displayed to the user on an output display device.
Patent CA-2234221-A1 (CA)
Inventor: FISCHER KLAUS
IPC: D21C3/22
Filed: 1996-09-26
Abstract: The aim of the invention is to determine the point in time during pulp cooking at which the viscosity and/or kappa number of the pulp produced have predetermined values. Since these values can be determined only after the cooking process, appropriate models must be used. To that end, use is made of a neural network whose initial value is the desired viscosity and/or kappa number from which the requisite cooking time can be determined and whose initial values are measurement values of the cooking process. According to the invention, the neural network is adapted during the course of a continuous cooking reaction on the basis of a dynamic model of the changing measurement values. Suitable measurement values during pulp cooking are in particular the SO2 content of the cooking acid and the colour value and electrical conductivity or pH value. In the associated arrangement, the model (10) used is a combination of analytical models (101 to 103, 201 to 204) of the process variables with the neuronal network (100, 200).

Title: Railway hazard acoustic sensing, locating, and alarm system
Inventor: STEPHENS ROBERT DOUGLAS
IPC: B61K9/10
Filed: 1998-08-11
Abstract: A highly reliable early warning system is disclosed. The warning system provides immediate detection of railway activity and early warning of dangerous railway conditions to train crews and to Rail Traffic Control offices. The warning system has acoustic sensors coupled to one of the rails of a railway for detecting sound or vibration transmitted from physical events. The detected acoustic signals are analyzed by a computer sound recognition system to ascertain the nature of the event causing the signal. If a suspect condition is identified or an unrecognized high energy acoustic signature is detected, an alarm is generated. The alarm signal may be transmitted over any communication system to the Rail Traffic Control office and to the trains traveling toward the suspect track location. The system can also detect railway rolling stock problems such as flat spots on wheels or derailed cars. When desired, the alarm may employ wireless transmissions to stop the trains remotely. When more than one acoustic sensor detects the same event, the exact location can be determined. Any physical events that are detected may be stored in a sound file. These may be catalogued as to location, time and suspected event for retrieval and analysis later.

Patent CA-2244975-A1 (CA)
Inventor: MARCZAK JEAN-MARC
IPC: G06F7/72
Filed: 1997-01-21
Abstract: Multiplications on a finite field of cardinal 2<m> may be achieved by means of a multiplier circuit including j shift registers (R0, ..., Rj-1) into which dual-base co-ordinates of one operand are initially loaded, j being an integer greater than 1 divisor of m. The other operand is expressed in standard base. The shift registers are linked to combinatorial logics arranged to deliver the dual-base co-ordinates of the product of the two operands in m/j clock cycles, with j co-ordinates being delivered in each cycle. Multiplication execution rates may thus be increased relative to previously known dual-base multipliers that required at least m clock cycles per operation. The multiplier circuit is particularly useful in BCH decoders.
