Title: Multi-dimensional data processing and display
Inventor: HUTSON WILLIAM H
IPC: G01S7/20
Filed: 1991-12-13
Granted: 1998-12-29
Abstract: A multi-dimensional processing and display system is used with a sonar tracking system (30) to monitor ocean-going vessels (32).  The system arranges data in a three-dimensional matrix, which is then reformatted into a two-dimensional matrix.  The two-dimensional matrix is decomposed into singular vectors and singular values.  Certain data elements in the two-dimensional matrix are enhanced or diminished by modifying selected singular values.  Certain data elements in the two-dimensional matrix are enhanced or diminished by modifying selected singular values.  A history database is maintained by saving certain of the singular vectors, which is concatenated with the two-dimensional matrix.  An enhanced two-dimensional matrix is generated by multiplying the two-dimensional concatenated matrix by the modified singular values and the singular vectors.  After data enhancement, the two-dimensional enhanced matrix is reformatted back into a three-dimensional matrix.  All or portions of the enhanced three-dimensional matrix can then be displayed.

Granted: 1998-11-24
Abstract: La présente invention porte sur un système décisionnel de recouvrement de signaux d'horloge comprenant des circuits qui servent à empêcher les verrouillages erronés et à accélérer l'acquisition des configurations de symbole connues. Le système de recouvrement de l'invention comprend au moins deux circuits de commande. Chacun d'eux a une largeur de bande effective et produit un signal d'horloge. Le système de recouvrement échantillonne le signal de données reçu en utilisant deux signaux d'horloge (573, 575) au moins et produit un premier et un second échantillon de signal correspondant. Ces échantillons sont utilisés pour produire des signaux de décision de symbole correspondants (581, 583). Ces signaux subissent un traitement qui cherche à détecter les configurations de symbole connues dans le signal de données reçu (513). Quant une suite binaire connue est détectée, les caractéristiques du système de recouvrement de signaux d'horloge sont modifiées; plus exactement, les largeurs de bande effectives des circuits de commande sont modifiées.

Title: Signaling method for packet network and system
Inventor: IWATA ATSUSHI
IPC: H04L12/721
Filed: 1993-12-24
Granted: 2000-01-25
Abstract: A method which achieves a reduction of the virtual channel connection delay time in signaling without using permanent virtual channels (PVC) and without performing wasteful allocation of signal bandwidth. When a transmission terminal transmits a packet, a packet transmission control section requests transmission of a signaling packet to a signaling transmission section. The signaling transmission section searches a VC and signal bandwidth table and sends out, when a virtual channel is registered and a required signal bandwidth is provided, a packet using the virtual channel. When the signal bandwidth is insufficient, it requester from the packet switching system only a sufficient signal bandwidth and then sends out the packet. When no virtual channel is registered, the signaling transmission section requests a signaling packet from the packet switching system. The table includes, for each destination address, a virtual channel timer for releasing the virtual channel applied thereto after the virtual channel is held for a predetermined period of time after completion of transmission, and a bandwidth timer for reducing the signal bandwidth after each predetermined interval of time after the completion of transmission. At each end of a packet transmission, the two timers are reset to a clock.

Patent CA-2149225-C (CA)
Inventor: SHERWOOD WILLIAM LYON
IPC: C21C5/56
Filed: 1992-11-12
Granted: 2002-01-08
Abstract: The invention is a process for steelmaking in a rotary furnace from a solid metallic charge adapted to realize greatly in-creased heat transfer and melting rates and thereby greater steel production.  A hot liquid metal bath is maintained over the length of an oxy-fuel fired rotary furnace. Solid metallic scrap is continually introduced by way of a charge end opening into a melting zone, wherein the bath melting point temperature is depressed on the order of 300 degrees Celsius at the furnace charge end, by means of coincident additions of supplementary carbon into the melt. The effect is a multifold increase in temperature differen-tial between the flame temperature and the temperatures of the furnace walls and charge, with a proportionate increase in the quantity of heat transferred. In order to maintain this depressed temperature, a corresponding increased quantity of cold solid scrap is required to be charged into the melt and advanced along the furnace, according a dramatic production rate increase in relation to the prior art. The preferred embodiment provides an intermediate annular dam which substantially confines unmelted solid charge to the melting zone, over which melted metal overflows into an all-liquid refining and temperature-composition ad-justment zone preceding discharge, with overall firing and furnace interior gas flow countercurrent to the general charge move-ment, thus allowing the steel discharge temperature to be controlled independently of the heating rate. Other benefits include in-creased refractory life, less oxidation of charge and refractory constituents, and substantially less particulate and pollutants discharged in the process off-gas.

Title: Class library for use in graphics programming
Inventor: EICK STEPHEN GREGORY
IPC: G06F9/44
Filed: 1995-05-16
Granted: 1999-08-31
Abstract: A library of C++ classes for use in writing data visualization  programs. The library embodies a general design principle for class libraries: that the classes are partitioned into entity classes and functionality classes.  Entity classes in the library specify properties of areas in a display and the functionality classes specify functionalities which the areas may have, for example,  being responsive to the mouse or the keyboard or being capable of executing drawing commands.  The classes are narrowly defined, and when the C++ programmer specifies a class for an object, he or she can give the object exactly the desired properties by selecting from among the area classes and the functionality classes.  Because properties are acquired by inheritance, code generated using the libraries is shorter and faster than code generated using conventional class libraries.

Abstract: A nonreusable medical device has a needle (34) for injecting or collecting fluid which is retractable by depression of a plunger (54) slidingly mounted in the medical device. A fron t- mounted retraction mechanism (22) has a needle holder connected to the needle. The needle holder is supported along the axis of the device by means of a frictionally engaged retainer ring (102) member coupled to the needle holder along an axially aligned sliding interface, The needle holder and retainer ring are positione d in the front portion of a hollow body. The front of a movable member or plunger presses against the retainer member passing around the needle holder which cannot move forward, thereby separating die retainer member from the needle holder. The separation occurs by gradually inducing the extent of the sliding interface area until the retainer member pops loose from the needle holder whereupon the needle holder and needle are retracted into a cavity in the plunger in response to a retraction force applied to the needle holder by a previously compressed spring.

Abstract: A trellis coded modulation system comprises a source of successive 2-bit data symbols X1, X2 arranged in a frame format wherein each frame comprises a plurality of data segments each including a plurality of groups of interleaved data symbols.  Each group of interleaved data symbols is separately coded by a precoder and convolution encoder to derive coded output symbols Z0, Z1, Z, which are mapped to respective 8-level symbols for transmission together with periodically generated frame and segment sync symbols.

Each first decoder preferably comprises a reduced complexity  Viterbi decoder responsive to a partial representation of the state of the linear filter. Each group of received symbols may also be directly applied to a respective second Viterbi decoder for estimating data bits X1 X2.  Estimated data bits X1 X2 from the first or second decoders are selected for further processing.
