Inventor: HEIDLER RALF
IPC: G01V3/32
Filed: 2003-11-24
Abstract: A method is provided for gathering information on the pore pressure in an earth formation surrounding a wellbore. The method includes the initial steps of selecting at least one suitable property (e.g., porosity, drilling fluid composition, etc.) of the drilling environment (which is defined by the wellbore and the surrounding formation) and at least one NMR parameter (e.g., T2 distribution) in an NMR measurement response. The method selects a suitable property for which values over a plurality of wellbore depths can be correlated with the characteristics or behavior of the pore pressure in the earth formation. The method further includes conducting an NMR measurement at a plurality of wellbore depths, thereby generating an NMR response from the drilling environment. The measured values of the NMR parameter in the NMR response are then correlated with values of the suitable property. Next, the values of the suitable property are compared over the plurality of depths, and then the correspondence between the property values is correlated with the behavior of the pore pressure over the plurality of depths. In this way, the characteristics of the pore pressure in the earth formation over the plurality of wellbore depths are determined.

Abstract: A method for identifying interferers in a radio communication band, such as the 2.4 GHz ISM band, uses a priori information of the interferers such as channel structure; channel frequency and channel bandwidth. Measured RSSI cats be used to detect and identify interferers. RSSI measurements can be made at multiple frequencies within a channel of the interferer. Randomization of RSSI measurements improves the likelihood of interferer detection and identification if such interferer is present. Metrics other than RSSI can be used.

Title: Long-lasting crustacean bait for use in traps and method of making the same
Inventor: TEUNE RICKY J
IPC: A01N63/10
Filed: 2003-12-18
Abstract: An improved bait for use in attracting crustaceans in traps and pots is disclosed which is particularly long-lasting when used in such traps and pots in any of a wide variety of underwater environments, together with a preferred method for making the crustacean bait. The improved crustacean bait is made of hides such as cowhides which are processed to remove the hair therefrom, and then is cured and cut into pieces of an appropriate size for use as crustacean bait in traps or pots. The pieces of improved crustacean bait may be packaged in sealed bulk packages which do not require refrigeration. The improved crustacean bait is very long-lasting when placed into a trap or pot in the ocean, and will neither decompose over an extended period of time nor degrade in its attractiveness to lure crustaceans over an extended period of time.

Title: Wear resistant center feed impact impeller
Inventor: BRITZKE ROBERT W
IPC: B02C13/18
Filed: 2002-07-25
Abstract: The present invention is particularly, but not exclusively, useful for reducing wear of component parts of impact crushers caused by earth aggregat e flows during operation of impact crushers. The present invention includes a stepped central feed cone (12) that allows for cylindrical carbide rods (44) to be press fit therein to reduce wear. The downward steps of the stepped co ne (12) urge material fed to the stepped cone outwardly to the table. The top surface (35) of a first rod inserted into a first bore (34) formed in the impeller housing extends a distance beyond the bottom (31) of a second bore on the next step up. The first rod protects the housing material forming the second bore from being washed out by material flow. In one embodiment, the impeller shoes have a geometric shape (61) that reduces the excessive normal forces and accompanying high friction of the material against the shoe. The reduction in high friction significantly reduces the wear rate.

Title: Method and system for enhanced data searching
Inventor: MARCHISIO GIOVANNI B
IPC: G06F17/30
Filed: 2002-08-14
Abstract: Methods and systems for syntactically indexing and searching data sets to achieve more accurate search results are provided. Example embodiments provide a Syntactic Query Engine ("SQE") that parses, indexes, and stores a data set, as well as processes natural language queries subsequently submitted against the data set. The SQE comprises a Query Preprocessor, a Data Set Preprocessor, a Query Builder, a Data Set Indexer, an Enhanced Natural Language Parser ("ENLP"), a data set repository, and, in some embodiments, a user interface.  After preprocessing the data set, the SQE parses the data set and determines the syntactic and grammatical roles of each term to generate enhanced data representations for each object in the data set. The SQE indexes and stores these enhanced data representations in the data set repository. Upon subsequently receiving a query, the SQE parses the query similarly and searches the indexed stored data set to locate data that contains similar terms used in similar grammatical roles. In this manner, the SQE is able to achieve more contextually accurate search results more frequently than using traditional search engines.
