  • Patent number: 6754097
    Abstract: A data storage device includes a resistive cross point array of memory cells. Each memory cell includes serially-connected first and second resistive devices. Each resistive device has programmable first and second resistance states. The data storage device further includes pluralities of first, second and third conductors, and a read circuit. Each first conductor is connected to data layers of a column of the first magnetoresistive devices; each second conductor is connected to data layers of a column of second magnetoresistive devices; and each third conductor is between reference layers of a row of first and second magnetoresistive devices. The read circuit applies different first and second voltages during read operations. The first voltage is applied to the first and second conductors crossing a selected memory cell; and the second voltage is applied to the third conductor crossing the selected memory cell.

  • Patent number: 6754847
    Abstract: Methods and systems are provided for monitoring a loosely coupled system, such as a web-based system and a business-to-business (B2B) system. In the case of a web-based system, exchanges between a web client and a web server may be monitored to determine quality and performance of the web-based system. The exchanges may include objects and attributes communicated from the web server to the web client. The exchanges may also include information about actions performed on objects as a user navigates through web pages displayed by the web client. For example, when the user selects a hyperlink, the monitoring system may recognize the hyperlink as an action. Accordingly, the actions along with the objects and their associated attributes may be recorded. The objects and their associated attributes may then be retrieved from the web server and the recorded actions may be played back against the retrieved objects based on the recorded attributes and the retrieved attributes.

  • Publication number: 20040117371
    Abstract: An authorisation privilege for an access request is inferred when no explicit privilege exists. The inference can be performed by way of mining occurrence patterns or derived from user hierarchy, profile, click history, transaction history or role. For any access request, the respective explicit privilege or inferred privilege is verified by the database or security administrator before the access request is permitted. Conditions expressed in an access policy are evaluated on the occurrence of predefined events. The events extend beyond user access requests, and include external events, composite events and access of a referential type. The access policy is framed in ‘event, condition, access enforcement’ terminology. The access control rules can be parameterised and can be instantiated by data obtained from inference rules associated with the conditions of the policy. The conditions have an evaluation component and an inference component.

  • Publication number: 20040115489
    Abstract: Transport of water in a fuel cell system between a first gaseous stream having a higher concentration of water and a second gaseous stream having a lower concentration of water, by mass and heat transfer, is effected through a plurality of non-hydrophilic membranes in a membrane module, such that water uptake of the selective layer is less than 10 wt % measured at a water activity of 0.9 and at a temperature of 30° C.; the membrane has a minimum pressure-normalized water flux of 100 GPU at 50° C., and maintains an ideal selectivity of water over any remaining component in the gas mixture greater than 5 at 50° C. Water and heat are transferred from an exhaust stream from either the cathode or anode compartment of a PEM fuel cell into an incoming reactant stream, whether oxidant or fuel. Operation is at a temperature above 50° C. and water activity greater than 0.

  • Publication number: 20040117803
    Abstract: The invention describes a methodology and a system for dynamically specifying exceptions and exception handlers for an application written in any computer language, which has exception handling facility. The methodology described in this invention decouples the exception handling logic from the application thereby can be used to alter the behavior of the program/module/application as well as to define new types of exceptions at runtime. The decoupling of the exception handler logic eliminates the language dependence of the application and further helps in customizing the behavior of the application when they are being deployed in new environments. Moreover dynamic exception handling is not operating system dependent.

  • Patent number: 6748570
    Abstract: A method and apparatus for a data processing system for accessing classes and methods in an object oriented system. Responsive to receiving a selected user input to a container, a view event is sent from a view controller to an application mediator. The view event identifies an action taken to generate the selected user input. A request is selectively generated based on the view event, wherein the request event includes a major code identifying a class name as a destination and a minor code identifying a method name a function to be invoked. The request event is sent to a transporter. The transporter acts as a router to send the request event to an appropriate destination object from a plurality of destination objects. Responsive to receiving the request event at the transporter, the request event is sent to a destination object within a plurality of destination objects based in the class name.

  • Publication number: 20040107171
    Abstract: A user's preference structure in respect of alternative “objects” with which the user is presented is caputured in a multi-attribute utility function. The user ranks these competing objects in order of the user's relative preference for such objects. A utility function that defines the user's preference structure is provided as output on the basis of this relative ranking. This technique can be used to assist a buyer in selecting between multi-attribute quotes or bids submitted by prospective suppliers to the buyer.

  • Patent number: 6740703
    Abstract: A thickened aqueous coating composition (preferably paints and the like or adhesives) containing a film-forming polymeric binder which produces dried coatings having less sensitivity to water by using a thickener which is autoxidizable. Preferred autoxidizable moieties are provided by long chain fatty acids of the type used in alkyd paints and association is the preferred thickener mechanism. The moieties may form part of a compound which can take part in a copolymerization to form a cellulose-free polymeric backbone for the thickener and if the compound is not very soluble in water, the copolymerization mixture is subjected to intensive agitation to form droplets of less than 500 nm number average diameter which compensates for the lack of solubility. The thickener may serve as a binder if sufficient amounts are used.

  • Patent number: 6735463
    Abstract: A method for generating a velocity-indicating, tomographic image of a sample in an optical coherence tomography system includes the steps of (a) acquiring cross-correlation data from the interferometer; (b) generating a grayscale image from the cross-correlation data indicative of a depth-dependent positions of scatterers in the sample; (c) processing the cross-correlation data to produce a velocity value and location of a moving scatterer in the sample; (d) assigning a color to the velocity value; and (f) merging the color into the grayscale image, at a point in the grayscale image indicative of the moving scatterer's location, to produce a velocity-indicating, tomographic image. Preferably a first color is assigned for a positive velocity value and a second color is assigned for a negative velocity value.

  • Publication number: 20040087072
    Abstract: A method of forming an active device is provided. The method includes performing a first patterning operation on a first plurality of layers. This first patterning operation defines a first feature of the active device. Then, a second patterning operation can be performed on at least one layer of the first plurality of layers. This second patterning operation defines a second feature of the active device. Of importance, the first and second patterning operations are performed substantially back-to-back, thereby ensuring that the active device can accurately function.
