  • Patent number: 7693693
    Abstract: Output feedback pole placement problems with parameter drift are solved with stabilizing solutions. Changes in system parameters trigger alerts in an automated manner. A representative method includes determining a set of solutions for an output feed pole placement problem, based on parameters of a physical system. The solutions are stable and well-conditioned for monitoring changes to the parameters of the physical system. The physical system is adjusted, or controlled, based on the solutions determined. Updated parameters of the physical system are acquired. A set of updated solutions for the output feedback pole placement problem are determined based on the updated parameters. The physical system is then adjusted, or controlled, based on the updated solutions determined. A system manager may also be notified of the updated parameters and/or the updated solutions. Furthermore, changes within the system may be monitored, and/or potentially critical changes within the system may be detected.

  • Patent number: 7680643
    Abstract: A portable device is connected to a host system that operates according to a first industry standard architecture (e.g., a personal computer built according to the IBM Personal Computer standard). The user initiates a session in the host system using the software and data in the portable device. The user suspends the state of the session, the state is stored in the portable device, and the user disconnects the portable device from the host. The user later connects the portable device to a second host that operates according to a second industry standard architecture (e.g., Apple Macintoshâ„¢ computer). The second host boots an autoconfiguring host operating system stored in the portable device and starts a virtual machine layer also stored in the portable device. The user then resumes operation of the suspended virtual machine layer session.

  • Patent number: 7571446
    Abstract: It is one object of the present invention to provide a server, a computer system that can efficiently operate a server, an object management method and a server control method. For each web page that is presented to a user terminal, a server predicts the times whereat users will issue the next requests, i.e., the times NA whereat objects held by the server will be used, and manages objects stored in the main storage based on predicted use times NA. In the process employed for swapping an object out of the main storage, basically the object is swapped out whose predicted use time NA is the latest.

  • Patent number: 7562004
    Abstract: A better configuration for a computerized system is determined by performing a first stage and a second stage. In the first stage, the performance of each system configuration, including candidate configurations and a standard configuration, is evaluated, and the number of scenarios needed in the second stage is determined. In the second stage, the performance of each scenario of the standard configuration is evaluated, and the mean thereof is determined. For each candidate configuration, the performance of each scenario of the candidate configuration is evaluated, and the mean thereof is determined. Where the candidate configuration's mean is greater than the standard configuration's mean by a threshold, it is selected as the better configuration. Where no candidate configuration's mean is greater than the standard configuration's mean by the threshold, the standard configuration is selected as the better configuration.

  • Patent number: 7552226
    Abstract: Provides methods, systems and apparatus for timer management of an element processing system wherein timer intervals related to elements to be processed can be handled in a time-efficient manner. An example method is a method for detecting a timeout of elements in an element processing system wherein a timer value, indicating a timeout interval with respect to a given time base, is assigned to each of the elements when processed. From a number of elements processed, the timer value indicating a minimum timeout interval to expire is determined out of the number of timer values assigned to the number of elements being processed.
