Abstract: A hydrocarbon control system includes a base device, a field device, and a mobile device. The base device includes a key generator configured to generate a temporary key. The field device is configured to restrict or allow access based on verification of a received key. The mobile device is configured to communicate with the base device to receive the temporary key when in proximity of the base device, communicate with the field device to provide the temporary key to the field device when in proximity of the field device, and exchange data with the field device in response to the field device verifying the temporary key.

Abstract: A spider for high-power, compact electro-acoustic transducers comprises a non-woven fiber blend encased in a thermoplastic elastomer. The spider is capable of supporting the longer stroke distances of the high-power, compact electro-acoustic transducers and exhibits improved fatigue and ageing resistance.

Abstract: Embodiments of the invention provide a system and method of automatically generating weights for matching data records. Each field of a record may be compared by an exact match and/or close matches and each comparison can result in a mathematical score which is the sum of the field comparisons. To sum up the field scores accurately, the automatic weight generation process comprises an iterative process. In one embodiment, initial weights are computed based upon unmatched-set probabilities and default discrepancy weights associated with attributes in the comparison algorithm. A bulk cross-match is performed across the records using the initial weights and a candidate matched set is computed for updating the discrepancy probabilities. New weights are computed based upon the unmatched probabilities and the updated discrepancy probabilities. Test for convergence between the new weights and the old weights. Repeat with the new weight table until the weights converge to their final value.

Abstract: Facilitating the purchase of at least one resource is disclosed. Data is received from a set of one or more external applications. An approved purchase requisition is received. Information associated with the purchase requisition is validated. The purchase requisition is converted into a valid purchase order. The valid purchase order is exported to the set of one or more external applications.

Abstract: A method and system for providing multi-organization resource management. According to one embodiment of the invention, data is imported from a set of one or more external applications, a purchase requisition is generated from resource data from the set of one or more external applications. Then, after the purchase requisition is approved and validated the purchase requisition is converted to a purchase order and exported to one or more external applications.

Abstract: A software system efficiently procures operating resources within an enterprise. A requisition record generating module generates a requisition record for a requisition. The requisition record indicates at least an operating resource that a requestor desires to purchase. The requisition record generating module generates the requisition record responsive to a combination of input by a requestor and operating resource information in an operating resource information database. An approval path determining module. responsive to the requisition record and to approval rules in an approval rules database, determines an approval path for the requisition record, among various ones of a plurality of possible approvers, required to approve the requisition record. An approval path handling module guides the requisition record along the determined approval path, and the approval path handling module generates a global approval indication in response to the requisition record successfully traversing the approval path.

Abstract: A polyaniline is characterized by a nuclear magnetic resonance spectrum in its leuco form showing only two .sup.13 C peaks, indicating the substantal absence of chain branching, and preferably by a molecular weight (M.sub.p) above 90,000 and up to about 170,000 (more especially 100-140,000). Oriented films of such polyanilines in the protonated emeraldine oxidation state have electrical conductivities up to at least around 500 S/cm.They may be made by oxidizing aniline in aqueous solution with a persulfate under the combination of conditionsthat the acidity of the solution throughout the reaction is such that if its temperature is adjusted to 20.degree. C. it will have a pH in the range from about -0.2 to +3.0;that the temperature of the solution is in the range from -5.degree. to about -40.degree. C.
