Abstract: The present invention implements parallel processing in a Database Management System. The present invention provides the ability to locate transaction and recovery information at one location and eliminate the need for read locks and two-phased commits, The present invention provides the ability to dynamically partition row sources for parallel processing. Parallelism is based on the ability to parallelize a row source, the partitioning requirements of consecutive row sources and the entire row source tree, and any specification in the structured query language (SQL) statement. A Query Coordinator (802) assumes control of the processing  of an entire query and can execute serial row sources (804, 806). Additional threads of control, Query Servers, execute parallel operators. Parallel operators are called data flow operators (DFOs). A DFO is represented as SQL statements can be executed concurrently by multiple processes, or query slaves. A central scheduling mechanism, a  data flow scheduler, controls a parallelized portion of an execution plan, and can become invisible for serial execution. Table queues are used to partition and transport rows between sets of processes. Node linkages provide the ability to divide the plan into independent lists that can each be executed by a set of query slaves. The present invention maintains a bit vector that is used by a subsequent producer to determine whether any rows need to be produced to its consumers.  The present invention uses states and a count of the slaves that have reached these states to perform its scheduling tasks.

Abstract: A control system for the operation of the subsurface safety valve is dis-closed. The control system uses a pressurized gas chamber, as well as a shuttle valve which connects to the main fluid pressure supply from the surface. The shuttle valve is connected to the gaseous chamber as well as to a barrier piston. As a result of the arrangement, leakages between the downstream side of the operating piston and the shuttle valve result in a reestablishment of the pressure balance on the operating system which allows the subsurface safety valve to close. Additionally, in the event of loss of gaseous pressure, the same pressure-balancing effect occurs on the operating piston, which allows the subsurface safety valve to go to a closed position. The configuration of the control system, which includesa gaseous chamber, allows for disconnection of the hydraulic fluid supply beforethe predetermined depth is reached to facilitate the connection of a tubing hanger.

Abstract: A surface acoustic wave device includes at least diamond, a single crystal LiNbO3 layer formed on the diamond, and an interdigital transducer formed in contact with the LiNbO3 layer and uses a surface acoustic wave (wavelength: .lambda.n .mu.m) in an nth-order mode (n = i or 2). When the thickness of the LiNbO3 layer is t1 (.mu.m), kh1 = 2.pi.(t1/ .lambda.n.p ) and the cut orientation (.theta.,.PHI., and .PSI. represented by an Eulerian angle representation) with respect to the crystallographic fundamental coordinate system of the LiNbO3 layer are selected from values within specific ranges. Consequently, a surface acoustic wave device which increases the propagation velocity (V) of a surface acoustic wave and improves the electromechanical coupling coefficient (K2) is realized.

Granted: 2000-10-10
Abstract: In an NHRP (NBMA Next Hop Resolution Protocol) address resolution system for transforming a network layer address to a data link layer address in an NBMA (Non-Broadcast, Multi-Access) network not sharing media, an NHRP processing section provides a function of resolving an address while an ATMARP (Asynchronous Transfer Mode Address Resolution Protocol) processing section provides a function of resolving an address on the basis of the ATMARP. A holding section is selectively accessed by the NHRP processing section or ATMARP processing section for holding address information registered by the NHRP or address information registered by the ATMARP. When the NHRP processing section receives an NHRP resolution request packet requesting for a resolution of the address of a given ATMARP terminal's address, the processing section sends, if the ATMARP terminal and a terminal sent the NHRP resolution request packet do not belong to the same subnetwork, a reply representative of the address information of an interface received the request packet.

Abstract: A method of and apparatus for curing or minimizing the problem of web "fluting" or "corrugating" in printed webs of paper printed on heat-set web-offset printing presses resides in spreading the web in its width-wise direction as the printed web exits from the ink drying and heat setting oven of the press and passes over the web cooling chill rolls downstream from the oven, thereby to hold the printed web in a flat and smooth condition until it is cooled and has taken a permanent set. The method and apparatus facilitate operation of the press at higher speeds and with lighter grades of paper than conventional, and provide for increased production efficiencies, lower costs, enhanced print quality, and access to new markets for web-offset printing.

Abstract: A method of enabling an on-board vehicle navigation system to compute a route from a current position of the vehicle to a desired destination is provided. A user of the navigation system in a vehicle utilizes a cellular telephone or any other wireless, two-way audio communications link to contact an operator in a remote communications center. The user informs the operator of his desired destination. The operator in the communications center accesses a computer database to determine the exact location of the desired destination in terms of latitude/longitude, street address, or other similar information. The operator then causes the information specifying the exact location to be transmitted from the communications center to the on-board vehicle navigation system over a data link. The on-board vehicle navigation system receives the location information and uses it to compute a route from the vehicle's current position to the desired destination.
