Fault tolerant state machine for configuring software in a digital computer
Software configuration changes are made in a digital computer by executing selected opcodes to add new features. When executing each opcode, a persistent record is kept of execution of each elementary command of the opcode. To recover from a failure of execution of an opcode, remediation opcodes are executed for a known error, or else the persistent record of execution is accessed to identify executed commands of the opcode, and the executed commands are reverted in reverse order by undoing changes made to the software configuration by the executed commands of the opcode. The resulting configuration of the digital computer is compared to a backup copy of the configuration existing at the start of execution of the opcode. If the reversion of the executed commands of the opcode has not reproduced the backup configuration, then the configuration of the digital computer is restored to the backup configuration. |

System for data migration using a migration policy involving access frequency and virtual logical volumes
In recent years, data life cycle management, in which data is relocated from, for example, a new storage sub-system to an older storage sub-system in accordance with how new the data is or the frequency of use of the data, has become important. One technology for achieving data life cycle management is technology for migrating the contents of a storage area (“volume”) of a storage sub-system to another volume without affecting the host computer that uses the volume. In the present invention, when an associated source volume (for example, the source volume in a copy pair association) of a pair of associated volumes is migrated, migration of an associated destination volume (for example, the target volume in the copy pair association) is also controlled. In this way, it is possible to control the migration of a pair (or a group) of associated volumes in accordance with the user's requirements. |

Systems and methods for handling non-volatile memory operating at a substantially full capacity
This can relate to handling a non-volatile memory (“NVM”) operating at a substantially full memory. The non-volatile memory can report its physical capacity to an NVM driver. The NVM driver can scale-up the physical capacity a particular number of times to generate a “scaled physical capacity,” which is then reported to the file system. Because the scaled physical capacity is greater than the NVM's actual physical capacity, the file system allocates a logical space to the NVM that is substantially greater than the NVM's capacity. This can cause less crowding of the logical block addresses within the logical space, thus making it easier for the file system to operate and improving system performance. A commitment budget can also be reported to the file system that corresponds to the NVM's physical capacity, and which can define the amount of data the file system can commit for storage in the NVM. |

Method of monitoring a portable electronic device and a server for monitoring same
A system for locating and monitoring electronic devices utilizing a security system that is secretly and transparently embedded within the computer. This security system causes the client computer to periodically and conditionally call a host system to report its serial number via an encoded series of dialed numbers.

This multilevel metadata about metadata improves the efficiency of search and analysis of the metadata content within the networked system. The methods facilitate search of varying scope both within and across the registries, directories and registry-directories focused on different problem oriented domains. Maintaining the integrity of these problem oriented domains serves to improve the efficiency of search throughout the system. |

The invention relates to a method of determining the distortions in the projection system of a TEM, and a method of correcting for these aberrations. The aberrations are determined by collecting a large number of images of a sample, the sample slightly displaced between each acquisition of an image.
