Patent CA-2123951-C (CA)
Inventor: YAMADA KENJI
IPC: H04L49/111
Filed: 1994-05-19
Granted: 1999-03-02
Abstract: In an output-buffer switch for an asynchronous transfer mode, comprising a plurality of input buffer sections each for temporarily storing cells coming in through a respective input line, a time-division multiplexing section for time-division multiplexing the cells from the input buffer sections, and a plurality of output buffer sections each for temporarily storing the cells from the time-division multiplexing section which are meant for a respective output line, the output buffer sections each has a cell buffer, and a buffer occupancy ratio calculator which calculates an occupancy ratio of the cell buffer on the basis of the address information of the trailing and leading cells stored in the buffer.  When the occupancy ratio exceeds a predetermined threshold, the calculator generates a buffer occupancy state signal.  Each input buffer section has a buffer controller, an address filter, cell buffers, and a buffer selector.  On receiving a buffer occupancy state signal from any output buffer section, the buffer controller controls the address filter, cell buffers and buffer selector such that cells addressed to the output buffer section, which is about to overflow, are temporarily stored in the cell buffer other than the cell buffer used when the buffer occupancy state signal is absent.  These cells are fed out from the buffer when the occupancy ratio decreases to below the threshold.  As a result, when any one of the output buffer sections overflows, it is recovered immediately without cells being discarded.

Title: High-density optical wavelength division multiplexing
Inventor: KNOX WAYNE HARVEY
IPC: H04J14/02
Filed: 1994-09-21
Granted: 1999-05-18
Abstract: The present invention provides an apparatus and method for high-density optical wavelength division multiplexing (WDM) using a single optical source.  An optical wavelength division multiplexer in accordance with the present invention includes an optical source providing an optical pulse signal.  A wavelength splitter separates the optical pulse signal spectrum into a plurality of channel signals at different wavelengths such that each channel signal may be separately modulated or otherwise processed.  A wavelength combiner then recombines the separately modulated channel signals to provide a high-density WDM optical signal particularly well-suited for use in optical circuit interconnection and optical communication network applications.  The high-density single-source multiplexer of the present invention may also be conveniently adjusted to align channel signal wavelengths or to compensate for optical fiber dispersion.

Abstract: A method and system for calibrating and controlling the with-drawal of a fluid, such as blood, from a fluid source, such as a blood vessel, includes a fluid pump (26), a pressure sensor (24), a flow rate sensor, and a microprocessor based flow control subsystem. The flow control subsystem optimizes the flow rate by sensing zero flow rate pressure within the subject, making a plurality of periodic flow path pressure measurements and extrapolating a calibration flow rate curve (I10). A control curve (130) is generated by utilizing the zero-flow rate pressure point ( 100), the slope of the calibration curve ( 110), and an empirically predetermined pressure offset value (150). The blood pump (26) is then operated at a maximum speed that is limited by the flow control curve ( 130) to maximize flow without occlusion or collapse of the blood vessel during blood withdrawal. The method and system of the invention is particularly applicable to automated apheresis system.

Granted: 2002-05-28
Abstract: Disclosed are a method of the in situ purifi-cation by aeration and biofiltration, of water from lakes, bays, and aquacultural and within waste water treatment systems. In a first step, polluted, nutrient rich and/or oxygen deficient water is drawn, from with the water body, usually near the bottom, into a submerged chamber located near the surface of the water body, to cause the water to be oxygenated, in part, from three potential sources of oxygen, air used in the airlift to bring the water to the submerged chamber, then air diffused from the surface as the moving water is brought in contact with the atmosphere and finally from supplemental aeration diffused within the deeper portion of the submerged chamber so that the rising bubbles operate in a counter current manner to the water flow providing efficient gas exchange. In a second step, the water that has been oxygenated is passed through a biofilter comprising a filter bed made of filtering media, which is located within the water body. The filtering media may be preinoculated with beneficial micro-organisms and essential nutrients. Also disclosed is an apparatus for use to carry out this purification method. The same apparatus can also be used to provide hypolimnetic aeration within a lake without destratifying the water column outside the apparatus. It can further be used to draw organic sludge or sediments from the body of the water body and bring these solids in contact with a continuous or intermittent supply of microbial cultures specifically grown to optimize production of enzymes, which solubilize said organic sludge of sediment. Biochemical oxygen demand (BOD) generated by the sludge solubilization can then be treated by aeration and biological filtration. The apparatus for sludge solubilization is designed to avoid the suspension of solids in the water column beyond the limits of the apparatus.

Title: Frame erasure or packet loss compensation method
Inventor: CHEN JUIN-HWEY
IPC: G10L19/00
Filed: 1995-08-14
Granted: 1999-11-02
Abstract: A method and apparatus for improving the performance of coding systems in the presence of frame erasures or lost packets. The encoded signal ismodified after transmission but prior to decoding by a decoder preprocessor. Thepreprocessor recognizes that a given frame has been corrupted and modifies the encoded signal so that the decoding thereof will result in improved coding system performance. Specifically, based on the decoding process and on a predetermined target signal, the encoded signal is modified so that the decoding thereof will generate an approximation to the target signal. In a first illustrative embodiment, a CELP speech coder is used and the target signal is an excitation signal comprised of all-zero excitation vectors. In this case, the portion of the corrupted excitation signal indices which identify the corresponding gain factors are set to values which represent a low gain factor. In a second illustrative embodiment, a CELP speech coder is used and the target signal comprises an extrapolation of the excitation signal represented by the encoded signal for one or more previous frames. In this case, the preprocessor encodes the extrapolated excitation signal using the best codebook matches available. In either case, the effect of corrupted frames in the reconstructed speech signal is minimized.
