Cantilever device and cantilever controlling method
The amplitude control of a cantilever based on the van der Pol model is performed through feedback using measurement data on a deflection of the cantilever. A self-oscillating circuit integrates a deflection angle signal of a cantilever detected by a deflection angle measuring mechanism using an integrator, multiplies a resulting integral value by linear feedback gain generated by a gain generator, and an output corresponding to the linear feedback signal is generated. Also, the self-oscillating circuit cubes the deflection angle signal using analog multipliers, integrates the resulting values using integrators, multiplies the resulting integral values by a nonlinear feedback gain generated by a gain generator, and an output corresponding to the nonlinear feedback signal is generated. Furthermore, the self-oscillating circuit adds the outputs together using an adder, and a voltage signal for a piezo element is generated. |

Reconciliation of multiple sets of network access control policies
In general, techniques are described for managing multiple access policies in a network access control system. An endpoint device may send, to a policy decision point (“PDP”), a request to communicate on a network. When the PDP receives such an access request, the PDP typically identifies a set of access policies to be enforced with regard to the endpoint device and causes the identified access policies to be enforced with regard to the endpoint device. These access policies may specify rights to communicate on networks and/or rights to communicate with server resources and/or endpoint configuration requirements. However, because the endpoint device may issue multiple access requests, conflicting sets of access policies may potentially be enforced with regard to the endpoint device. The techniques described herein ensure that only a consistent set of access policies are enforced with regard to the endpoint device when accessing the network. |

Mechanism for implementing thread synchronization in a priority-correct, low-memory safe manner
A mechanism is disclosed for implementing fast locking in a multi-threaded system. This mechanism enables fast locking to be performed even on an operating system platform that does not allow one thread to assign ownership of a lock on a mutex to another thread. In addition, the mechanism performs locking in a manner that ensures priority correctness and is low-memory safe. In one implementation, the priority correctness is achieved by using operating system mutexes to implement locking, and the low-memory safe aspect is achieved by pre-allocating a memory section to each thread. This pre-allocated memory section ensures that a thread will have sufficient memory to obtain a lock, even when a system is in a low-memory state. With this mechanism, it is possible to implement locking in a safe and efficient manner. |

Methods and systems for a receiver to allocate bandwidth among incoming communications flows
Disclosed are methods and systems for a receiver to autonomously allocate bandwidth among its incoming communications flows. The incoming flows are assigned priorities. When it becomes necessary to alter the allocation of bandwidth among the flows, the receiver selects one of the lower priority flows. The receiver then causes the selected flow to delay sending acknowledgements of messages received to the senders of the messages. In most modern protocols, senders are sensitive to the time it takes to receive acknowledgements of the messages they send. When the acknowledgement time increases, the sender assumes that the receiver is becoming overloaded. The sender then slows down the rate at which it sends messages to the receiver. This lowered sending rate in turn reduces the amount of bandwidth used by the flow as it comes into the receiver. This frees up bandwidth which can then be used by higher priority flows. |

Method and apparatus for controlling multicast group subscriptions
A method and apparatus for controlling multicast group subscriptions in a multicast distribution circuit is presented. When a router included in the multicast circuit receives notification to terminate support of a particular multicast group (group leave request), data flow with respect to that multicast group is initially maintained on the communication link coupling the router to the hosts. Queries are issued to hosts on the communication link to determine whether continued support of the particular group is desired by any hosts coupled to the communication link. If, while waiting for a positive response to the queries issued, a request to join an additional multicast group is received, bandwidth availability on the communication link is examined to determine if adequate bandwidth is available for supporting the newly requested group addition. If adequate bandwidth is available, the newly requested group is added to those groups supported on the communication link. However, if adequate bandwidth for support of the newly requested group is not available, one or more groups that are pending termination (group specific queries have been issued for these groups) are selected for early termination in order to make enough bandwidth available to support the newly requested group addition. The selection criteria utilized to determine the groups to be terminated may be based on a variety of parameters. |

Scalable system for partitioning and accessing metadata over multiple servers
In an aggregated file system, metadata is partitioned into multiple metadata volumes. On receipt of a file processing request, a file switch examines its mount entry cache to identify a target metadata volume that hosts the metadata of the requested file. The identification begins with mount entries at a root volume and continues recursively by examining a portion of the absolute pathname of the file until the target metadata volume is identified. Finally, the file switch forwards the request to a metadata server managing the target metadata volume. Since the identification process is carried out completely within the file switch, there is no need for multiple expensive network accesses to different metadata servers. |

End user oriented workflow approach including structured processing of ad hoc workflows with a collaborative process engine
In a structured workflow system, a configurable workflow engine provides mechanisms for executing and scheduling the work items in a defined way. End users use their discretion and define their own “local” processes and “local” rules for processing work items, or deviate from predefined processes. The configurable workflow engine might be installed at a server to organize workflows and business processes where end users can define processing steps for incoming work items by setting up rules and defining workflows as part of a local workflow structure. By defining these rules and workflows, the further processing steps of future incoming work items can be automated. When an administrator directs the workflow engine to move from a current phase to a next phase, the workflow engine deals with the incomplete items by allowing the administrator to carry over work items (or might do it automatically). End-user consultation might be included in the carry-over decisions. The carried over work items are added as parallel activities to the next phase. The workflow engine handles imposing and executing control flow dependencies between tasks, thus providing a smooth transition from totally unstructured work to semi-structured or completely structured work. When the workflow engine encounters semantically correlated work items/tasks, the process engine assumes that these work items/tasks belong to the same process instance. |

Substrate processing method, program, computer-readable storage medium, and substrate processing system
In a pattern measuring unit installed in a coating and developing treatment system, the height of a pattern formed on a substrate is measured using the Scatterometry method. Based on the measured height of the pattern, an appropriate number of rotations of the substrate during application of a coating solution is calculated, so that the rotation of the substrate during the application is controlled by the calculated number of rotations of the substrate. Since the number of rotations of the substrate when the coating solution is applied to the substrate is controlled, it is unnecessary to stop the system which performs photolithography processing on the substrate, resulting in improved productivity of the substrate. |
