Patent number: 7693693Abstract: 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.Type: GrantFiled: July 20, 2008Date of Patent: April 6, 2010Assignee: International Business Machines CorporationInventors: Mei Kobayashi, Kaiyang Yang

Patent number: 7680643Abstract: 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.Type: GrantFiled: November 17, 2005Date of Patent: March 16, 2010Assignee: International Business Machines CorporationInventors: Mandayam Thondanur Ragnunath, Chandrasekhar Narayanaswami
