Abstract: A system for treating a polar liquid includes a signal generator for providing an alternating electrical current, and a transducer electrically coupled to the signal generator. The transducer includes a solenoidal coil and two ferromagnetic end pieces at the ends of the coil and transverse thereto. In operation, the transducer is at least partially immersed in a polar liquid and, when energized with the current provides a magnetic field into the liquid, the field may change a property of the liquid, e.g. an interfacial mass transfer rate. This can be used in many different industrial applications.

Abstract: For changing a property of a polar liquid a device comprising a signal generator and a transducer is provided adjacent to the liquid or at least partially immersed therein. The signal generator provides an alternating electrical signal to the transducer, wherein the electrical signal is of a frequency and an amplitude to affect the transducer to produce an alternating magnetic field having a magnetic flux density so as to change the property of the polar liquid, wherein a portion of the magnetic field penetrates the liquid, having an effect thereon and providing a change in the property of the liquid at a distance of at least 1 meter from the transducer. The property is a gas exchange rate and the change is at least 5%, or the property is surface tension and the change is at least 1%, or the property is viscosity and the change is at least 0.5%.

Abstract: For changing a property of a polar liquid, a transducer including a solenoidal coil is disposed at least partially within the liquid, which is prevented from penetrating the interior of the coil. An alternating electrical current applied to the coil produces a magnetic field about the coil. The current has a frequency and an amplitude such that the magnetic field has an effect on the liquid changing a property of the liquid at a distance of at least 5 meters from the transducer, wherein the property is gas exchange rate, surface tension, viscosity, freezing point, or partial vapor pressure. A system may include two transducers, wherein the electrical currents are offset in phase or frequency for controlling the effect.

Abstract: NIC collected network statistics are captured by agent devices resident on Host machines of a network. A probe (software or hardware) retrieves the collected statistics from one or more monitored hosts (each host on the network, for example) and places them in RMON MIB and RMON extension MIB formats. The MIB data is retrieved by queries from a data correlation device that then correlates the queried data into useful statistics regarding network traffic. The useful statistics include network traffic in bytes per second for each application, application protocol, hosts, user logon id, etc. for each of the monitored hosts. Different views including a host to host matrix view are provided in a split window display.

Abstract: Methods and devices for rejuvenating, supplementing, or bypassing an individual fuel cell or a group of fuel cells, in a fuel cell stack, is disclosed. The methods and devices provide for a mechanism for removing catalyst poisons on both the anode portion and the cathode portion of the fuel cell and providing an improvement in the operation of the electrolytes. A controller that controls a variable resistor or a variable power supply in parallel with an individual fuel cell or a group of fuel cells in a stack is utilized. Adjusting the resistive value of the variable resistor, or the voltage level of the variable power supply, directly controls the current in the fuel cell. In accordance with Kirchoff s Current Law, decreasing the fuel cell voltage increases the current through the fuel cell, while the fuel cell stack is operational, and poisons deposited on the anode and cathode electrocatalysts are removed, thereby rejuvenating the fuel cell.

Abstract: A framework for extending a network management platform, including an object manager that retrieves an entire class hierarchy including any code or other functionality needed to retrieve data about a server or other network device (e.g., code needed to retrieve actual instances of an object of the class). The object manager holds the object hierarchy and initiates retrieval of actual instances of the object. The class hierarchies are maintained in plug-in type Object Providers. Newly developed network technologies are managed via managed objects defined by class hierarchies held by the Object providers. The Object Provider can be seamlessly installed in an existing extensible network management platform.

Abstract: An architecture for a management information system includes a backend that services information requests from a front end. The backend retrieves data from management information base(s) (MIBs) and prepares a response to the information requests. The backend maintains a cache of data recently retrieved from the MIBs and uses the cache to retrieve data, instead of making additional requests to the MIBs. The responses may be prepared from cache data only, MIB data only, or a combination of both. The back end is preferably maintained on a same segment of a network as the MIBs. Multiple MIBs may be queried from the back end, and the backend may coordinate with back ends on other segments of the network.
