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. |

Method for wind noise reduction
A noisy signal is picked up by a microphone, digitized by an Analog to Digital Converter and fed to a processor for analysis and wind noise reduction. Most of noise reduction methods are based on the assumption that the interfering noise is stationary or slowly varying compared with speech. This assumption allows “learning” the characteristics of the noise between speech pauses and, based on a noise estimate, to build different filters that reduce the noise. In the case of wind noise this basic assumption is not valid. Wind noise is highly non-stationary, its power and spectral characteristics vary greatly. Because wind noise is not stationary, regular noise reduction methods cannot be used to reduce wind noise. For reducing wind noise effects in a device, the presence of wind should be detected reliably and then a novel approach presented here must be applied to eliminate the wind noise. |

Exemplary embodiments are directed to a redundancy scheme for bay protection in Substation Automation (SA) that prevents a single failing Intelligent Electronic Device (IED) of the SA system from impairing the operation of a bay of a substation. A protection IED assigned to a home or host bay of a substation of an electric power system performs the protection functions of the bay to which it is assigned, plus protection functions of at least one of its neighboring bays. As a result, each bay can be managed by two different protection IEDs, wherein redundancy is achieved without a dedicated redundant protection IED for each bay. Whenever required to do so, the protection IED receives, from appropriate sensors, information about a status or value of a process quantity from the neighboring bay, computes or executes protection functionality such as overcurrent, overvoltage or earth fault on behalf of the neighboring bay, and issues commands directed to actuators of said neighboring bay. |

Methodology to optimize and provide streaming object rotation using composite images
Optimizing and presenting various sequences of images and/or photographs for viewing with a Web browser, is accomplished without the necessity of loading the entire image set, for example in connection with the 3D display of a product of interest. To represent an object that is rotating, a set of images must be taken. These images are taken at various angles, typically using either using a fixed camera or a turntable. The illusion of an object being rotated is created when the captured images based on the angle being viewed are displayed. To ensure a seamless rotation of an object, a technique is taught that significantly concentrates on reducing the loading time of the captured images by prioritizing which images should be transferred first according to their size, and their number of object views or view angles. A seamless rotation is thus achieved while less than the total number of images is loaded. In fact, an embodiment of the invention teaches that, by selectively loading certain images with specific angular values, it is possible to achieve an object rotation, i.e. using horizontal and vertical adjacent images positioning. |

Relay device, network system, route switching method, and recording medium
When a failure occurs in a link or another relay device, a route control unit updates a routing table stored in a current routing table. Upon update, it acquires inhibit target route information indicating a route likely to cause a micro-loop in the updated routing table and registers it into an inhibit target table. If route update in an adjacent relay device is completed, an inhibit control unit deletes a route in which the adjacent relay device is set as a next transfer destination from the inhibit target table. A transfer processing unit determines a transfer route of a packet based on the current routing table and, if the determined transfer route is not registered in the inhibit target table, executes transfer of the packet. A micro-loop can be thereby reliably avoided when route switching in a network system where communication between plural networks is relayed by plural relay devices. |

A source-address independent, multi-path routing method for use in a communication network is disclosed. A network node uses an information packet's destination address to determine a plurality of neighbors it has a proportional likelihood to forward that packet to, such that packets can be sent over multiple paths to a destination node without undesirable looping.

Color mapping
A method of mapping colors which are outside a reproduction device's color gamut to reproducible colors uses a boundary of a reduced gamut. In a three-dimensional color space the reduced gamut is derived from the reproduction device's gamut by reducing its size in all three dimensions. Reduced-gamut clipping-vectors are determined by clipping the out-of-gamut colors onto the reduced-gamut boundary, and the out-of-gamut colors are mapped to those colors at which the reduced-gamut clipping-vectors intersect the reproduction device's gamut boundary. Thus out-of-gamut colors associated with clipping-vectors of different directions that are clipped onto the same point, or adjacent points, of the reduced-gamut boundary are mapped to points spaced apart, or spaced farther apart, on the reproduction device's gamut boundary. |

Optoelectronic range finder
A device for optoelectronic distance measurement includes an emitter having a first end for emitting a measuring beam to an object to be measured and a second end, a receiver for receiving the measuring beam reflected or dispersed back from the object to be measured and for converting it to a measurement signal, a signal processing device for filtering the measurement signal and a reference signal, and a control and analysis device for analyzing the information of the measurement signal and the reference signal so as to determine the distance from the object to be measured. The second end of the emitter is used to emit a reference beam which is received by the receiver and converted to form the reference signal. |

Projection optical system with rarefaction compensation
The present invention provides a projection optical system for projecting a pattern of an object plane onto an image plane, including a first lens whose refractive index irreversibly increases by ultraviolet irradiation, and a second lens whose refractive index irreversibly decreases by the ultraviolet irradiation. |
