Patent CA-2196480-C (CA)
Inventor: IGARASHI HIDEKI
IPC: H04L25/03
Filed: 1997-01-31
Granted: 2002-04-16
Abstract: A soft decision decoder including an adaptive equalizer and a reliability information generator. The reliability information generator, receiving soft decision data and equalized square error from the adaptive filter, performs delay detection of the soft decision data, and then rotates the phase of the delay detected data so as to match the data to transmitted data components.  The rotated data is weighted with the average value of the equalized square error to generate the reliability information for the soft decision Viterbi decoding.  This makes it possible to obviate the exponential or logarithm calculations which are conventionally needed for generating the reliability information for carrying out the soft decision Viterbi decoding of the output of the adaptive equalizer, and hence to reduce the enormous amount of calculations and the size of hardware like DSP for performing the calculations.

Abstract: Video storage is shown in which stripes of video data, derived from video frames or video fields, are written to respective magnetic storage disks. Each disk is provided with a unique serial number during manufacture and the position of a stripe within an image frame is mapped to these unique serial numbers. In this way, it is possible for the physical locations of the disks within the array to be changed while maintaining correct alignment of the stripes making up each image frame.

Title: Communication system with multiple center devices to alleviate network outage due to faults
Inventor: KUNIKYOU TOMOO
IPC: H04L69/40
Filed: 1996-11-11
Granted: 2001-05-08
Abstract: A communication system capable of reliably recovering its communication functions on its own when a fault occurs, and which can be used to construct a highly flexible network.          This communication system is configured so that a plurality of node devices (12) supporting data generating sources are connected via communication paths (13) that use ATM technology to a plurality of center devices (11), just as if it possessed distributed ATM switch functions.  When the communication paths (13) between two (2) node devices (12-2 and 12-3) are cut, the center device (11-2) detects the fault point, and autonomously recovers communication functions by transferring the node device (12-2) originally under its control to the control of the center device (11-1).  When this happens, the center device 11-2) cannot communicate via the communication paths (13) due to the fault, and must use a local communication means such as a wide area network (16) to communicate with the center device (11-1).

Abstract: The present invention relates to tools and methods for stabilizing incompetent or otherwise unstable subterranean zones or formations penetrated by a well bore during drilling. The methods basically comprise drilling the well bore through an unstable subterranean zone or formation when it is encountered, pumping a fluid through a well stabilization tool while moving the tool through the portion of the well bore in the unstable zone or formation whereby fluid jets formed by the well stabilization tool enlarge the diameter of the well bore by fluid jet erosion, pumping a hardenable cementitious material through the well stabilization tool while moving the tool through the enlarged portion of the well bore whereby the enlarged portion is filled with the hardenable cementitious material, allowing the cementitious material to harden and then drilling the well bore through the hardened cementitious material.

Title: Call patterns in a communications network
Inventor: THOMAS IAN PETER
IPC: H04M3/50
Filed: 1996-09-18
Granted: 2001-03-13
Abstract: In a communications network, call records are generated by a plurality of originators (CLI#1, CLI#2, CLI#3) making calls to a service provider (180).  The call records are stored in a database (145) which forms part of the billing function (140) of the network. The call records for the service provider (180) are collated and sent to the service provider for processing.  The service provider is provided with a system for analysing the call records to establish the number of lost callers, rather than the number of lost calls.  This is possible since the call records include the CLI information of the originators. This information, gathered over a predetermined period of time, allows the service provider (180) to estimate the number of answering stations (170) necessary to optimise call answering and minimise the number of lost callers.

Abstract: A spray gun for applying a liquid spray coating, such as paint, to a surface incorporates a light source system for gauging the position of the spray gun relative to a worksurface in order to optimize application of the coating to the surface.  The light source is preferably in the form of a laser which emits a pair of light beams toward the worksurface.   The pair of light beams converge toward each other in a direction toward the surface, and the position of the beams on the surface is used by the operator to judge the distance of the spray gun from the surface. An adjustment mechanism is interconnected with one of the light beam sources, so as to adjust the point of convergence of the light beams. A  closable door is associated with the spray gun housing at one of the light beam emitting locations, to selectively prevent emission of one of the light beams from the spray gun, such that a single light beam is emitted from the spray gun for use as a reference for spot application of the coating to the surface.

Granted: 2000-04-04
Abstract: A disposable and interchangeable roasting pan/cover features a base panel with a side wall about its perimeter. A platform for supporting a food product is positioned on the interior surface of the base panel. A handle recess may form the platform so as to define a handle upon the exterior surface of the base panel. Alternatively, a pair of side wall recesses in the interior surface of the side wall may define handles on the side wall exterior surface while enhancing the structural strength of the pan/cover. A rim is disposed about the outer edge of the side wall and features an even number of staggered tongue and groove features. Two of the pan/covers may be oriented with their rims abutted so that one pan/cover serves as a cover for the other serving as a pan. The tongue and groove features of the two pan/covers engage one another so that the cover oriented pan/cover does not slide off of the pan oriented pan/cover holding the food product.

Abstract: A treadmill (10) includes a frame (12) on which are mounted transverse forward and rearward roller assemblies (16, 18). An endless belt (20) is trained about the forward and rearward roller assemblies. A deck (24) is positioned between the upper run of the belt and the frame. The rearward portion of the deck (24) is hinted to the frame by pivot brackets (70) mounted to the frame to allow pivoting of a deck about an axis extending transversely to the length of the deck. Preferably, the pivot bracket (70) is of unitary construction, but of sufficient flexibility to allow the relatively free pivoting of the rear portion of the deck in relationship to the frame. Elastomeric cushions or springs are supported by the forward portion of the frame to underlie and support the forward portion of the deck and to absorb impact toads imparted on the deck by the user. A pivot wall (90) extends downwardly from the rear portion of the frame (12) to support the rear of the deck and also to raise and lower the rear of the treadmill deck relative to the forward end of the treadmill deck, thereby to provide an adjustable incline for the deck.

Abstract: The start operation of the gas turbine starting method is improved with bleed valves being first throttled, then fully opened and then fully closed at 90% speed, thereby fluid unstableness phenomenon is suppressed and starter motor power is reduced. While inlet guide vane (11) and variable stator vanes (C1 to C5) are opened to predetermined settings from starting to rated speed, bleed valves (1, 2, 3) are open to a predetermined setting until speed is elevated to 52% for the bleed valve (1) and until a speed is elevated to 51% each for the bleed valves (2, 3). Then the bleed valves (1, 2, 3) are fully opened until the speed exceeds 90%, when they are fully closed for rated operation. In the prior art, the starting operation is done with bleed valves being first fully opened until the speed is elevated to 90% and then fully closed. In the present invention, the air discharged into the ambient air can be reduced and thereby starter motor power can be also reduced.
