Abstract: An embodiment of a communication system includes a client device adapted to receive a location object that includes tracer information, and to perform one or more location object-based actions using the location object. The client device stores the tracer information and location object usage information, which describes the one or more location object-based actions that have been performed using the location object. The client device also sends the stored information to a server. The system also includes the server, which is adapted to receive the location object usage information and the tracer information reported by the client device. In an embodiment, the system also includes a service provider adapted to initiate a billing event, which may include generation and transmission of a bill to a sponsor entity based on an evaluation of the location object usage information and the tracer information reported by the client device.

Abstract: The inflow of liquid metal into a continuous casting mold is set by a closure device. A measured actual meniscus value is fed to a controller determining a closure device target position on the basis of the actual and a corresponding target value. The measured actual value is fed to a disturbance variable compensator. The target position/corrected target position or a corresponding actual value are further fed to the disturbance variable compensator which determines the disturbance variable compensation value. The disturbance variable compensator has a model of the continuous casting mold for determining an expected value. A number of oscillating compensators determine a frequency disturbance proportion. The sum of the frequency disturbance proportions corresponds to the disturbance variable compensation value. The disturbance variable compensator has a jump determiner, by which it determines the jump compensation value by integrating the difference.

Abstract: In a multi-stand rolling mill train, a strip successively runs through individual rolling stands. The strip—always as seen in relation to a rolling center line—is threaded into each of the rolling stands with known respective head offset and inlet-side head pitch, and therefore a strip head emerges with the respective head offset, a respective outlet-side head pitch and a respective outlet-side head curvature. The respective outlet-side head pitch is determined on the basis of respective inlet-side head pitch and pass reduction which takes place in the respective rolling stand. The respective outlet-side head curvature of the strip is determined based on respective measured and further data. The respective outlet-side head curvature is used to determine a respective control intervention for the respective rolling stand and/or the one arranged directly downstream and to drive the corresponding rolling stand in accordance with the respective determined control intervention.

Abstract: The invention relates to a method for suppressing the influence of roll eccentricities on the run-out thickness of a rolled stock, which runs through a rolling stand, roll eccentricities being identified by using a process model and taken into consideration in the determination of a correction signal for at least one final control element, preferably a final control element for the adjustment position, of the rolling stand, wherein the measured tensile force upstream of the rolling stand is fed to the process model to identify the roll eccentricities. According to the invention, variations in tensile force are fed back in a targeted manner to reduce the effects of periodic roll eccentricities on the rolled stock, whereas all other sources of variation are eliminated. A process model of the rolling nip and the rolls, preferably based on the observer principle, produces reliable data on the roll eccentricity.

Abstract: A method is provided for adjusting the inflow of liquid metal into a continuous casting mold using a closing device. The partially solidified metal strand is drawn out of the continuous casting mold. A measured actual value of the casting level is fed into a casting level controller, which derives a target setting for the closing device. The measured actual value and a target setting of the closing device are fed to an interference compensator, which determines an expected value for the casting level, which is subtracted from the measured actual value. The difference is fed to a differential controller that derives a controller output signal therefrom, which is multiplied by a superposition factor and superimposed on the target setting as an interference compensation value. An inflow signal derived from the actual setting is further superimposed on the controller output signal and fed to an integrator, which generates an output signal corresponding to the expected value for the casting level.

Abstract: In an information appliance system 100, a user device 108 comprises a client platform (200, FIG. 5) that includes a service framework (235, FIG. 5) to discover and connect with a variety of services, both remote and local, transient and persistent, and to disconnect from them when they are no longer of interest or become unavailable. The service framework 235 provides a standard, consistent, simplified way for services to make themselves available and for service-using entities to locate and connect with the services of interest to them. From the perspective of the client platform 200, all services, whether local or remote, are presented as local services to the application. Each remote service is represented as a local service through the use of a local proxy that insulates the service user from the complexities of communicating with a remote server. Various methods of operating a service framework are also described.

As a result, platform resources and security are maintained.

Abstract: A method and device are provided for casting a strand of liquid metal which is cast into a mold, and which is drawn as a strand out of the mold. The casting level, e.g., a level of the liquid metal in the mold, is regulated to a predetermined casting-level desired value using a casting-level controller having at least one integrator. The output of the integrator of the casting-level controller is replaced by a predetermined value when the difference between the casting-level actual value and the casting-level desired value exceeds a tolerance threshold.
