Title: Evaluation of the content of a data set using multiple and/or complex queries
Inventor: NELSON PHILIP C
IPC: G06F17/30
Filed: 1996-12-31
Granted: 2006-03-21
Abstract: The invention enables evaluation of the content of a set of data to determine whether the data set satisfies one or more queries. The invention enables rapid evaluation of large numbers of data sets much more rapidly than has previously been possible, even when the number of queries is large and/or the queries are complex. The queries are evaluated using an execution plan of query terms that is constructed from one or more specified queries by translating each query term of each query into one or more evidence descriptors and one or more combination operators, and operably relating each of the combination operators to at least one of the evidence descriptors or other combination operators, such that each query is defined by one or more of the evidence descriptors and one or more of the combination operators that are operably related to each other. Preferably, none of the evidence descriptors or combination operators are duplicated in the execution plan. The invention can be used to evaluate data sets of a variety of types, such as text documents and databases. The invention can be further optimized to achieve rapid evaluation of a data set with respect to the queries in two steps. First, one or more candidate queries that may be satisfied by the data set are identified by approximately evaluating each query. Second, each of the candidate queries is fully evaluated to determine whether the candidate query is satisfied by the data set.

Abstract: A method and apparatus of expanding tubulars is the disclosed. In the preferred embodiment, a rounded tubular is inserted through a larger tubular while suspended on a mandrel. A stop device, such as a liner hanger, is attached to the larger tubular after delivery downhole on the mandrel. Upon engagement of the liner hanger or other stop device to the larger tubular, the mandrel is freely movable with respect to the stop device. The mandrel contains a deforming device such as a comically shaped wedge located below the tubular to be expanded. A force is applied from the surface to the mandrel, pulling the wedge into the tubular to be expanded.   When the wedge clears through the tubular to be expanded, it releases the stop device so than the stop device can be retrieved with the mandrel to the surface.  Thus, the stop device is supported by the larger tubing while the smaller tubing is expanded when the wedge is pulled through it. Should the tubular being expanded contract longitudinally while it is being expanded radially, it is free to move away from the stop device.

Title: A method and system for communication access restriction
Inventor: HAMDY-SWINK KATHRYN ANNE
IPC: G06F21/31
Filed: 1997-06-18
Granted: 2001-10-23
Abstract: A network-based telecommunications system and method that restricts the dial-in access to a resource of a subscriber to only a communication from an authorized user of the source. A switch receives a communication directed to a subscriber from a calling party. Prior to connecting the communication to the terminating equipment associated with the subscriber, the switch requests processing information. An authentication unit determines whether the calling party is an authorized user by checking whether a passcode provided by the calling party corresponds to a passcode being held by the authentication unit.  If the passcode corresponds, then the authentication unit identifies the calling party as an authorized user, and the communication then may be connected to the terminating equipment of the subscriber. If the passcode fails to correspond, then the authentication unit fails to identify the calling party as an authorized user. The communication is not connected to the terminating equipment of the subscriber.

Title: A method and a device for maintaining the performance quality of a code-division multiple access system in the presence of narrow band interference
Inventor: TOBIA MICOLINO
IPC: H04B1/707
Filed: 1999-02-02
Granted: 2001-04-17
Abstract: A method and device which dynamically detects, tracks and filters interfering signals with sufficient speed (i.e. within one IS-95 CDMA data frame period, or 20ms) and fidelity to eliminate or greatly reduce the deleterious effects of narrow band interferon signals on a CDMA link. When inserted in an RF signal path an Adaptive Notch Filter (ANF) detects narrow band interferors above a threshold level within the CDMA signal. Detection is accomplished by continuous scanning of a preset excision band, e.g. a specified narrow band associated with an AMPS system. Detected interferors are then automatically acquired and suppressed. This is achieved by electronically placing a rejection notch at the frequency of the interferors. Multiple notch filters may be used to simultaneously suppress multiple interferors. In the absence of interferors a bypass mode is selected allowing the RF signal to bypass the notch. Upon detection of an interferon, a switch is made to a suppression mode where the interferon is steered through a first notch section and suppressed. Alternatively, an external control line may be used to select the bypass mode so that the signal is allowed to pass the notch section, regardless of interferon content.
