Non-disruptive upgrade including rollback capabilities for a distributed file system operating within a cluster of nodes
Implementations are provided herein for non-disruptive upgrade including rollback capabilities for a distributed file system within a cluster of nodes. To continue availability of the file system to external clients during the upgrade process, nodes can be upgraded piecemeal, for example, in one implementation, one node at a time. When a node is undergoing certain stages of the upgrade process, external clients can be directed toward the remaining nodes of the file system that are not currently being upgraded, including already upgraded nodes, to perform client activity. During the upgrade process, a first subset of nodes can be running in an upgraded state while a second subset of nodes can be in a non-upgraded state, both providing access to external clients in a seamless manner. During the upgrade process, an administrator can decide to rollback any upgrades and return the distributed file system to its previous version (e.g., the version of the file system prior to starting the non-disruptive upgrade process). Hooks can be provided prior to, during, and after various stages of the upgrade or rollback process that can allow services of the distributed file system to be notified of certain events of the upgrade process, or execute service specific processes at distinct times during the upgrade process. At the conclusion of an upgrade or rollback process, the distributed file system can enter a committed state that finalizes the process and cements an upgrade or a rollback to a more permanent state. |

Control unit, output control method and program
It is possible to easily change CAM tables, which are used for executing an electronic CAM operation. A CAM computation program performs an electronic CAM operation, using a CAM table that is an array in which displacements of a slave axis of an electronic CAM are associated with phases of a master axis of the electronic CAM. A CAM table generating program receives input of a CAM definition variable that defines an electronic CAM operation to be realized by a motion control, and generates a CAM table in which a CAM curve is stored as an array corresponding to the inputted CAM definition variable. A microprocessor performs a CAM computation program using the CAM table. If the microprocessor receives the input of the CAM definition variable, the microprocessor performs the CAM table generating program to generate the CAM table, and stores the generated CAM table into the main memory. |

Aircraft navigation system and method of navigating an aircraft
An aircraft navigation system and navigation method. The system comprises a civil-certified GPS-receiver for determining first position information based on C/A-GPS-signals, and a military-type GPS-receiver for determining a second position information based on P(Y)-GPS-signals. A monitoring unit detects a first abnormal condition during jamming conditions within the C/A-GPS-signals. The unit compares the first position information with the second position information and detects a second abnormal condition when a difference between these position information is larger than a threshold value for more than a threshold duration. Upon detecting an abnormal condition, an alert procedure is initiated. In remotely piloted aircraft, Command & Control link-loss is also monitored and during link-loss, a transponder code automatically indicates communication failure. When in such situation an abnormal condition is additionally detected, a transponder code indicates airborne emergency and, subsequently, the aircraft navigation system is switched to navigating based on position information from the military-type GPS-receiver. |

Transducer measurement
A transducer such as a translinear proportional-to-absolute-temperature sensor uses two amplifiers, where each amplifier is used in a variety of modes. The first amplifier generates a measurement voltage though feedback in an analog circuit. The second amplifier samples and integrates the measurement in a switched-capacitor mode, and the output is stored on a capacitor. Then the first amplifier is set to measure its offset. The offset is sampled and integrated by the second amplifier, and the output is stored on a second capacitor. Then the first and second amplifiers are set to buffer the voltages stored on the capacitors. The measurement can then be offset-adjusted by digital or analog means. The adjusted measurement is then available to be used for calibration of, e.g., an image sensor. Other transducers, such as pressure sensors, strain sensors, gyroscopes, magnetometers, accelerometers, and xyz positioning sensors may employ the same dual amplifier approach. |

Process and seal coat for improving paint adhesion
Aqueous compositions useful as pretreatments prior to painting and to reduce the formation of rust in the uncoated condition consist essentially of water, an organo-functional silane, a compound of a Group IV-B element, and optionally a polyvinyl alcohol, stabilizing agents, wetting agents, thickeners, and biocides, and have an alkaline pH>7. A process for treating a metal surface includes contacting the surface with such an aqueous composition. The compositions and processes were found to have further benefits in comparison to the zinc phosphate metal pretreatment thought to be the standard in the industry. Preferably, the pH of the compositions is alkaline, which has been found to improve the efficacy of a silane as a surface treatment to improve uniformity of paint adhesion. By operating in the alkaline pH range, it was found that flash rusting and/or blush rust were significantly reduced. |
