Abstract: In a data communication system, a client and a server perform a data communication, in particular to provide the client with a instruction data set in response to a content data request message made by client. An instruction format configuration file contains a tree data structure having a plurality of instruction format nodes, each instruction format node indicating a particular combination of instruction elements constituting a particular instruction format and having associated with it a node selection criterion. The program extracts and determines properties from the content data request issued by the client. The program searches the tree data structure with the determined properties in order to find an instruction format node, whose associated node selection condition matches the properties. Thus, the instruction data set returned to the client can be provided in a flexible manner.

Abstract: Access to external service providers is provided through portlets, where each portlet accessible by a user is represented on the display of the user device. Through use of a dynamic content channel, e.g., a portlet, a highly customizable content page may be produced for any individual client system. When a portlet is selected on a user device, the content associated with the portlet is retrieved and automatically transformed into data that can be displayed by that user device. Thus, a particular user device is not limited to accessing content in a format identical to that associated with the user interface in use on the user device. Consequently, the user's ability to access a wide variety of content sources independent of the characteristics of the particular user device is further enhanced.

Abstract: Methods, system, and articles of manufacture consistent with the present invention provide for remote processing in a client/server system. A client has a first component of a service application and a server has a second component of the service application. The server sends a request to the client to execute the first component. The client initiates execution of the first component based on the received request. After initiating execution of the first component, the client instructs the server to initiate execution of the second component. Upon termination of execution of the second component, the server sends a completion indicator to the client indicating that the second component has terminated execution. The client terminates execution of the first component responsive to receipt of the completion indicator.

Abstract: Described is a single or multi-layered film having at least one polyamide layer (I) containing dispersed nanoscale nucleating particles. The smallest components of the dispersed nanoscale nucleating particles in layer (I) have an extension of less than 100 nm in at least one randomly selected direction for each component, based on a weighted average of all components of the dispersed nanoscale nucleating particles. Crystalline structures emanating from the surface of the dispersed nanoscale nucleating particles are formed after the layer (I) is cooled from the molten state at a rate of from 10 to 20° C. per minute. The dispersed nanoscale nucleating particles are present in the polyamide layer (I) in an amount of from 10 ppm to 3000 ppm, based on the total weight of layer (I).

Abstract: Described is a film having at least a single layer and at least one copolyamide layer (I) containing dispersed nanoscale nucleating particles. Crystalline structures extending from the dispersed particle surfaces are formed after the layer (I) is cooled from a molten state at a cooling rate of from 10° C. to 20° C. per minute. The dispersed nanoscale nucleating particles are present in layer (I) in an amount of from 10 ppm to 2000 ppm, based on the total weight of layer (I). Also described is a method of using the film of the present invention in packaging foodstuffs.

Abstract: Methods and systems consistent with the present invention provide an efficient manner of authentication for a plurality of services in a computing environment. When a first service of a plurality of related services is accessed, the user requesting access is provided with a security token that can be used by the user to efficiently access any one of the plurality of services on subsequent accesses. On subsequent accesses after the first access, the user may provide the requested service with the security token which ensures that the user is authorized to use that service. In this manner, the user only needs to provide its authentication information, e.g., log in, once to access any number of related services. This eliminates the need for multiple log-ins for multiple uses of a plurality of services thereby increasing speed, efficiency and reducing time and effort.

Abstract: A method and system for redirecting client requests includes a request handling program at the server. A client request is transmitted from a client via the request handling program to a primary application program. The primary application program generates a redirection instruction based on the client request and returns the redirection instruction to the request handling program. The request handling program, upon receiving the redirection instruction, forwards the client request to a secondary application program selected for serving the request. A response from the secondary application program is returned to the client via the request handling program. A communication session between the client and the primary application program may involve the use of internal resource locators and, for redirecting a client request, internal resource locators may be converted into external resource locators allowing the second application program to access a requested resource.

Abstract: Methods, systems, and articles of manufacture consistent with the present invention provide a data from a server to a client via a network, where it is determined to send the data to the client, a client information is obtained from the client based on the determination, and after obtaining the client information, the data is sent to the client.

An individual user can personalize the user device by specifying which service providers from among the ones the organization has made available via portlets, the user wants to use.
