Abstract: This relates to methods and apparatus for analyzing samples by fluorescence spectroscopy. In one embodiment, the methods and apparatus use a fluorescence detection unit (FDU) of a composition fluid analyzer (CFA™) module to detect variations in fluid properties (gradients) within an oil bearing column. Some embodiments enable efficient downhole fluid analysis in heavy oils where water/oil emulsions are present (water in dispersed phase and oil in the continuous phase). The principles described herein may also be applied when there are fine particles in the oil such as from unconsolidated sands.

Abstract: A method of producing a viscoelastic polyurethane foam coating in which a polyisocyanate is reacted with a polyol to form a prepolymer. The prepolymer is reacted with a polyol having at least one pendant carboxylic acid group to form a prepolymer with a pendant carboxylic acid group. The prepolymer with a pendant carboxylic acid group is neutralized with a tertiary amine and then reacted with water or an organic or inorganic polyamine. An energy absorbing unit in which the coating produced by the above method is provided on a viscoelastic polyurethane foam layer.

Abstract: A padded covering for parts of a chair, consisting of a padded material (2) with elastic properties at least within the thickness thereof, and covered with a semi-transparent, perforated mesh fabric, wherein said padded material has a three-dimensional structure that is at least partially visible through said fabric and comprises recesses opening out onto the fabric (3). Said covering is produced via a method comprising the steps of cutting out a suitably-shaped piece capable of covering the specific chair portion; stitching at least two concentric lines at the edges and over the entire periphery of the piece in order to flatten the edge region; cutting out, in a semi-transparent perforated mesh fabric (3), a correspondingly-sized piece; placing said semi-transparent fabric piece on top of the padded piece; and fastening the piece.

Abstract: A system and method for managing captured network traffic data is provided. The invention comprises a plurality of capture agents, each being configured to capture the network traffic associated with one or more applications. Each application is associated with one or more capture agents according to an application profile that is stored and maintained in a capture server. When analysis of an application's network traffic is required, the capture server contacts the corresponding capture agents according to the application profile. The capture server then effects the identification and archiving of the network traffic that corresponds to a user-defined capture condition. A database at the capture server maintains a record that associates the corresponding network traffic with the user-defined capture condition such that the corresponding network traffic can later be retrieved and analyzed using an analysis engine.

Abstract: Transactions within a transmission stream are identified that are related to an activity. The transactions are classified utilizing characteristics that identify the activity. Packets of the transaction are extracted from the transmission stream that corresponds to the activity. The extracted packets are presented in a visualization that identifies the packets and source and sink devices of the packets. The packets may be identified from a network trace. Classifying transactions includes identifying patterns present in packets to identify related transactions and/or packets that are temporally correlated. The characteristics may include heuristics related to a communication protocol of the transactions, examining temporal relationships of the packets, and/or identifying DNS requests related to the packets.

Abstract: A first capture system that captures network communication events related to an application, and a second capture system that captures internal processing events related to the application. A visualization system analyzes the data captured by each of the capture systems, synchronizes and correlates the data, and presents an integrated display of these communication and processing events. In a preferred embodiment, the communicated messages include an identifier of the application, and the processing components also associate an identifier of the application to each recorded processing event. To facilitate the integrated display of the events, the visualization system synchronizes the recorded communication and processing events to a common time base.

Abstract: A wood treating formulation is provided wherein the formulation is a mixture of a first solution containing styrene and a second solution containing furfuryl alcohol. A process for producing a wood treating formulation wherein the formulation is prepared by combining a first solution containing styrene and a second solution containing furfuryl alcohol is also provided.

Abstract: A furan polymer impregnated wood which comprises wood impregnated with a polymerizable furfuryl alcohol monomer mixture containing at least water and furfuryl alcohol, and an initiator selected from the group consisting of anhydrides, acids and combinations thereof is described. For longer storage life, the mixture contains a stabilizer selected from sodium carbonate, sodium bicarbonate, sodium citrate, phosphates and water-soluble lignin derivatives such as calcium and ammonium salts of lignosulfonic acids, and combinations thereof. A method for preparing a furan impregnated wood and uses thereof is also described.

Abstract: A method or system for optimizing a process for producing a cast or molded product made by one or more production steps in respect of one or more predetermined parameters towards one or more optimal values, the process comprising the steps of: defining one or more technical requirements for the cast or molded product; providing a simulation of the casting or molding process; generating with each computer implemented process one or more solutions for the production step concerned that will lead to a cast product that will fulfill the technical requirements; and determining in a further computer implemented process which combination of the individual solutions results in an actual process or in a selected sub-set of production steps in which the predetermined parameter is closest to the optimal value.

Abstract: Performance metrics related to the processing and propagation of messages related to select applications are collected during a simulation of a network. Each message associated with an application is tagged, and each simulated packet that contains some or all of a tagged message is correspondingly tagged to facilitate the creation of transmit records and receive records. A post processor is configured to collate transmit and receive records of each tagged message to identify delays associated with each node that processes the message, and each link that propagates the message from node to node within the network. The processed timing information is provided to the user via an interactive user interface that allows the user to view the timing information from an application layer perspective.

Abstract: Slow recovery viscoelastic polyurethane foam with a surface impregnation of silicone, coupled with a rigid helmet shell, is used for athletic headgear. The helmet shell should have a rigid construct to provide dispersion of impact energy, absorbing at least thirty percent of the impact energy delivered to the helmet shell. The slow recovery viscoelastic polyurethane foam has unique characteristics making it suitable for use as an energy absorbing liner for athletic headgear. The energy absorbing liner can be made with varying thickness and size, so retail establishments can custom fit a helmet to a particular customer.

Abstract: A furan polymer impregnated wood which comprises wood impregnated with a polymerizable furfural alcohol monomer solution containing at least water, stabilizers, and furfuryl alcohol, and at least one further compound selected from the group consisting of anhydrides, acids and combinations thereof is described. A method for preparing a furan polymer impregnated wood and uses thereof is also described.
