Title: Method for inputting and load balancing seismic data for seismic processing on a multiprocessor computer
Inventor: SCHOEN ERIC J
IPC: G01V1/28
Filed: 1994-12-01
Granted: 2000-02-15
Abstract: This invention provides a method for inputting seismic trace data to a seismic processing program running on a massively parallel processor (MPP) and for balancing the computational workload of individual processors. The MPP, consisting of a plurality of individual processing nodes connected by a data and control communications network, is treated as a bipartite system of "operator" nodes and "input" nodes. Opertor nodes apply mathematical operators to transform seismic data. Groups of seismic traces are loaded into the input nodes. The input nodes examine the data to determine which regions of the seismic survey are covered by the traces and how many traces cover each bin. The in put nodes then broadcast to all operator nodes a compact description of the trace coverage. The operator nodes then retrieve traces from the input nodes, using efficient data transfer mechanisms of the data network. The input nodes can be seen to serve as a distributed, content-addressable data cache. All nodes use the information in each broadcast to determine how many bins will be assigned to each "operator" node that will process the prestack data to produce poststack data. The bin assignment is designed to equalize the number of traces that each opertor node processes. Thus, the invention provides a means for maximizing the efficiency with which an MPP can perform seismic migration processing, and is applicable to wide variety of MPPs and processing algorithms.

Abstract: In a network-based communication system, communication trunks are allocated based on a history of network use and global event calendar information relating to particular regions that the network system services. A trunk allocation database is used for controlling the normal day-to-day trunk allocations to assign the trunks among the various network services. A global event calendar database containing holiday and event information observed by various countries and regions is provided for dynamically re-allocating the trunk assignments for trunks servicing a particular country or region when a holiday or event for that particular region occurs. The global event calendar database also informationally provides network users calling a particular region with timely information pertaining to holidays or events in the particular country or region that the user has called.

Title: Method for sharing network resources by virtual partitioning
Inventor: MITRA DEBASIS
IPC: H04Q11/04
Filed: 1997-02-14
Granted: 2000-07-18
Abstract: A method of operating a network by sharing resources associated with various classes among calls in the various classes according to a state dependent reservation parameter. Nominal amounts of one or more resources are allocated to each call class. When a call of a class of service operating in the network requires resources in excess of those allocated to the class, resources allocated to other classes of service are advantageously shared with the class of service. The sharing is based on a reservation parameter associated with the class of service of the call. The reservation parameter is advantageously a function of the network state. The role of the reservation parameter is to protect underloaded classes (i.e., those classes not using all of their allocated nominal capacity) from excessive borrowing by overloaded classes (i.e., classes using more than their allocated nominal capacity). More generally, the inventive method is used to determine if sufficient resources are available for routing calls and to route calls based on the determined available resources.

Abstract: The present invention relates to a molten steel refining method for refining molten steel, the carbon content of which is not more than 0.1 weight %, by blowing oxygen gas for decarburization at a blowing speed so that a cavity, the depth of which is 150 to 400 mm, can be formed on the surface of molten steel in a straight barrel type vacuum refining apparatus in which a straight barrel type vacuum vessel having no vessel bottom and a ladle are arranged. When necessary, the above decarburizing processing conducted by blowing oxygen gas is combined with: an A1 heating process in which A1 added into the vacuum vessel is burned by oxygen gas blown into the vacuum vessel at a blowing speed such that the cavity depth can be 50 to 400 mm; a degassing treatment conducted in a high vacuum condition; a desulfurizing treatment in which a desulfurizing agent is blown into the vacuum vessel; or a burner heating treatment in which a combustion improving agent is blown together with oxygen gas, wherein each treatment except for the high vacuum degassing treatment is conducted in a degree of vacuum of 100 to 400 Torr.

Abstract: Procédé de génération et de détection de signaux acoustiques portant des données alphanumériques, destiné à limiter les effets du bruit et, de ce fait, à améliorer la transmission de signaux, sans qu'il soit nécessaire d'amplifier la puissance du signal. Selon un aspect de l'invention, un signal acoustique spécial de multifréquence en code 2 (DTMF) consistant en une combinaison de deux fréquences est généré, pour la représentation d'un caractère alphanumérique particulier, qui est semblable à la tonalité DTMF standard. La différence entre les amplitudes des deux fréquences varie pendant la période de génération de la tonalité DTMF, de telle manière que les deux signaux atteignent un détecteur de destination finale, à savoir, un panneau de réponse vocale interactif, au moins pendant une partie de la période de génération, à une amplitude relativement similaire, ce qui augmente sensiblement les probabilités qu'ils soient reconnus en tant que signal DTMF.

The matching section has a variable circuit constant. A connecting section connects a transmission section to the reception section.  A supplying section supplies the transmission section to an input signal to make the transmission section produce the transmission signal in accodance with the input signal.  The supplying section adjusts the variable circuit constant in accordance with the input signal and the  demodulated signal.

Title: Mechanical clot treatment device
Inventor: WONG ROSE Y
IPC: A61M25/00
Filed: 1997-07-25
Granted: 2002-01-08
Abstract: This is a medical device. In particular, it is a surgical device usually delivered through an intravascular catheter. It may be used in several ways.  It may, for instance, be used to open a clear passageway adjacent thrombus to allow both blood and medication to bypass the clot. It may be used to pierce and to remove thrombus. These thrombus are often found in tortuous vasculature. The device includes several sections. The device has a core element, typically a core wire. Placed around the distal end of the core element is a collapsible but preferably self expanding cage assembly. The cage assembly is preferably radio-opaque. The proximal end of the cage is typically affixed to an actuator in such a way as to allow expansion of the cage after deployment. The cage assembly may have a generally conical distal or "trailing" portion when expanded and also a proximal section. The cage assembly may be used for collecting emboli or for displacing them to allow blood flow to resume. The proximal section may have various uses, e.g., for centering the collector assembly in the vascular lumen or for gathering larger amounts of the targeted clot or to act as a passageway for fluid flow. The assembly further may have an actuator which permits or causes the collector assembly to expand after deployment.
