| 20100037096 | System-directed checkpointing implementation using a hypervisor layer - While system-directed checkpointing can be implemented in various ways, for example by adding checkpointing support in the memory controller or in the operating system in otherwise standard computers, implementation at the hypervisor level enables the necessary state information to be captured efficiently while providing a number of ancillary advantages over those prior-art methods. This disclosure details procedures for realizing those advantages through relatively minor modifications to normal hypervisor operations. Specifically, by capturing state information in a guest-operating-system-specific manner, any guest operating system can be rolled back independently and resumed without losing either program or input/output (I/O) continuity and without affecting the operation of the other operating systems or their associated applications supported by the same hypervisor. Similarly, by managing I/O queues as described in this disclosure, rollback can be accomplished without requiring I/O operations to be repeated and I/O device failures can be circumvented without losing any I/O data in the process. | 02-11-2010 |

| 20100313393 | BALL PAPER CLIP DEVICE - The present invention relates to a ball paper clip for holding together two or more sheets of paper as using a ball. A clip ball is fitted into a guide hole formed in a clip body, and the papers are inserted between the clip ball and a support plate, so that the papers are clamped due to a natural phenomenon that the clip ball moves toward the lower end of the guide hole by gravity. The clip body or the clip ball is constructed to generate magnetic force so as to hold wire clips or pushpins. | 12-16-2010 |

| 20080272895 | Slim-Type Magnetic Buzzer - Contemplated magnetic buzzers include an elliptical or oblong resonator and magnet that significantly improve sound pressure level and audio quality. Most preferably, the resonator and magnet are disposed in a housing that comprises tab insertion channels that are fluidly coupled to solder channels, and tabs are coupled to and disposed within correspondingly shaped recesses in the housing to facilitate SMT mounting and to improve electrical contact stability. | 11-06-2008 |

| 20110062041 | Packing container having temperature adjustment functions, and apparatus and method for manufacturing the same - There is provided a packing container. The packing container has two different spaces formed by pressing edges of a carrier sheet, a function sheet and a middle sheet to each other to form a carrier space and a function space in both sides of the middle sheet, and thus two contents may be packed in one packing container, which leads to the simple packaging handling. | 03-17-2011 |
