Method and system for promoting a snapshot in a distributed file system
A method and system for promoting a snapshot in a distributed striped volume system is provided. A master volume server is configured with a rollback process such that when it is determined that a rollback is required, the master volume server sets a flag persistently in its own raid label on disk. After the persistent flag is set, the master volume server determines a “common snapshot,” and starts the process of sending RPC messages to each node hosting constituent volumes instructing each constituent volume to roll back to the identified snapshot. When the nodes receive this message a flag is set in the own raid label of each constituent volume and the volume then promotes the particular snapshot. If the master volume server has not received a successful response from each node that the snapshot promotion was successful within a specified time period, there is a retry. The common snapshot is then used as the active file system, thus providing data recovery for the striped volume set. |

Loop protection for a protective proxy
Protective proxies are used to shield a destination agent from undesirable source agents or transactions. Because protective proxies are usually tied to one but sometimes more fixed destination agents, they are usually configured directly to the destination agent. As a result, many protective proxies are lightweight and allow the destination agent to manage the protocol. As a result, a catastrophic condition can occur if the protective proxy is inadvertently misconfigured so that a connectivity loop occurs. A low level loop detected can be incorporated into the protective proxy. Alternatively, a loop detector which augments the existing application layer protocol can also be employed in a protective proxy. |

Accelerated throughput synchronized word stream cipher, message authenticator and zero-knowledge output random number generator
Systems and methods are disclosed, especially designed for very compact hardware implementations, to generate random number strings with a high level of entropy at maximum speed. For immediate deployment of software implementations, certain permutations have been introduced to maintain the same level of unpredictability which is more amenable to hi-level software programming, with a small time loss on hardware execution; typically when hardware devices communicate with software implementations. Particular attention has been paid to maintain maximum correlation immunity, and to maximize non-linearity of the output sequence. Good stream ciphers are based on random generators which have a large number of secured internal binary variables, which lead to the page synchronized stream ciphering. The method for parsed page synchronization which is presented is especially valuable for Internet applications, where occasionally frame sequences are often mixed. The large number of internal variables with fast diffusion of individual bits wherein the masked message is fed back into the machine variables is potentially ideal for message authentication procedures. |

Deterministic lookup using hashed key in a multi-stride compressed trie structure
An input lookup key is hashed and the hashed key divided into stride bits into a multi-level Trie structure. A compression function logically combines the stride bits to generate the compressed index bits into the stride tables. The bucket in the last stride table found by the hashed key may have several keys that collide at the same hash value. Discriminant bits are read from the key and select a stored key in the bucket table for verification of its result. Since the hashed key is a compression of the longer input key, more information is contained per bit of the hashed key than in the long key. The multi-stride lookup is performed first on the hashed key, allowing a faster convergence to the lookup result. The first stride can index a single hash table, with the remaining hash bits and discriminant bits used to select from among colliding keys. |

Variable rate feedforward control based on set point rate of change
A method of controlling a power generating unit or other process equipment with a slow reaction time includes creating a feedforward control signal to selectively include a fast response rate component or a slow response rate component based on the average rate at which a load demand set point signal has changed during a particular previous period of time. The method then uses the developed feedforward control signal to control the power generating equipment or other slowly reacting process equipment. In particular, a control method switches between introducing a fast or a slow response component within a feedforward control signal based on whether the change in the load demand set point over a particular period of time in the past (e.g., an average rate of change of the load demand set point signal) is greater than or less than a predetermined threshold. This method is capable of providing a relatively fast control action even if the expected load demand set point change is in a small range. In addition, this method does not require knowledge of the final or target load demand set point during the time in which the load demand set point is ramping up to a final target value and is not dependent on the ramp size, i.e., the ultimate difference between the load demand set point at the beginning of the load demand set point change and the final or target value of the load demand set point, making it more versatile than prior art systems. |

Methods and apparatus for antenna control in a wireless terminal
Base stations transmit strip signals using strip signal segments and self supporting modulation scheme techniques facilitating rapid channel estimate. A strip segment occupies one OFDM symbol time interval and uses a set of downlink tones; some, e.g., half, of the tones are left unused facilitating SIR measurement. The strip segments are advantageously timed to correspond to uplink access intervals in which connected wireless terminals do not typically transmit uplink signals. Connected wireless terminals including: multiple antennas used in combination, an antenna duplex module, single RF receiver chain and single RF transmitter chain, switch antenna coefficient combinations based on strip signal segment timing. The wireless terminal determines an independent downlink channel quality measurement, e.g., SNR and/or SIR for each strip signal segment and for on-going non-strip signaling. The wireless terminal compares channel quality measurements and selects an antenna coefficient combination to be used during non-strip signaling intervals obtaining very good antenna gain. |

Optimization and view dependency reduction for processing slice-based volumes
This invention describes an optimization and view dependency reduction method for multiplanar reformatting (MPR) of slice-based volume images. This method utilizes a traversal scheme that allows for efficient access of the computer memory layout of a sliced based volume, and therefore optimizes overall processing time. This method does not require changes to the volume memory layout or additional volume memory. Instead, efficient memory access is achieved by adaptive traversal patterns on the reformatting planes. The traversal pattern is adapted on-the-fly during rendering as the reformatting plane location and orientation is changed arbitrarily relative to the volume. In this way, the typical speed differences between various reformatting planes orientations caused by inefficient memory access is greatly reduced. Computer cache coherency, SIMD coherent implementation, and multiprocessing environments are also considered in the design of the traversal pattern. |

Method and procedure for compiling and caching VoiceXML documents in a voice XML interpreter
A method and system of compiling and caching voice application documents in order to provide more efficient retrieval of resources in a web-programming model such as in the VoiceXML domain. The method and system of the present invention requires that a voice application resource such as a VoiceXML document first be transformed into a representative object model before it is stored in the system's cache memory, and that this model becomes the voice application resource that is ultimately executed by the VoiceXML interpreter.

Method and apparatus for generating synchronization signals for synchronizing multiple chips in a system
A clock generator circuit for generating synchronization signals for a multiple chip system. The clock generator circuit comprises generation of a synchronization signal from a reference clock and chip global clock with edge detection logic. In high performance server system design with multiple chips, a common practice for server systems is to use feedback clock and delayed reference clock to generate the synchronization signal. The generated synchronization signal is transferred to latches clocked by the global clock to be used for chip synchronization functions. As the system clock frequency is pushed higher, the phase difference between generated synchronization signal clocked by feedback clock and receiving latch clocked by global clock is becoming such a large portion of cycle time that this signal cannot be transferred deterministically. This invention resolves the uncertainty problem and allows the synchronization signals to be generated deterministically independent of the chip global clock cycle time. |

Frequency offset correction circuit for WCDMA
Methods and apparatus for acquiring and verifying a code used by a base station. Acquisition time is reduced and circuitry simplified by performing Phase I and Phase II acquisitions in series, but in parallel with Phase III acquisition and verification, which are done in series. Phase III code acquisition is done by despreading the input signal using each of the possible codes in a code group. An estimation of the frequency offset between the base station and the terminal's local reference is used to correct the phase of the despread signals, which are coherently and non-coherently integrated. The largest accumulated value corresponds to the code used by the base station. The code is verified by despreading the received signal, applying a frequency correction, and demodulating. The demodulated output is a series of symbols, and a count of these symbols verifies the acquired code. |

System and method for synchronous payload envelope mapping without pointer adjustments
A system and method are provided for mapping information into Synchronous Payload Envelopes (SPEs). The method provides information bytes at a nominal system clock-based data rate, which is about equal to a system clock, but may be adjusted. An external clock has a rate approximately equal to the system clock rate. The method generates SPEs with identically-positioned information bytes, regardless of differences between the system and external clock rates. The SPEs are combined with Transport Overhead (TOH) and transmitted as a message frame at the external clock rate. SPEs are generated maintaining the positions of the information bytes within each SPE, without pointer adjustments, despite differences between the system and external clock rates. Expressed another way, message frames are generated with payload and TOH sections, and the information bytes are located exclusively in the payload sections. As a result, constant pointer values (e.g., H1/H2 or V1/V2) are maintained for all the SPEs. |

Communication buffer scheme optimized for VoIP, QoS and data networking over a power line
Media Access Control (MAC) layer transmit and receive buffering with multi-level prioritization. The receive buffering allocates receive buffers for receiving frame data from a PHY interface in priority order using both a static and dynamic buffer allocation, and delivers completed buffers queued in a multi-level priority queue to a host interface highest priority first. The transmit buffering delivers completed buffers queued in a multi-level priority queue to the PHY interface in priority order. When the multi-level priority queue contains a buffer that is higher priority than one being prepared for transmit, a priority-based interruption causes the transmit processing of the buffer to be suspended at its current state with the higher priority buffer taking its place. Upon completion of the higher priority buffer, the suspended buffer is resumed at its current state. |

Article for improved network performance by avoiding IP-ID wrap-arounds causing data corruption on fast networks
The reassembly timer in a TCP/IP receiver is dynamically set to avoid data corruption on fast networks caused by IP identification wrap-around. A sender generates IP packets with a special option specifying a reassembly time for fragments based on the subnet of the destination or on the calculated round-trip time of the connection. A receiver sets the reassembly timer to the reassembly time specified in the option. A sender can generate IP packets with an alternative option setting a time stamp for the generated packet. A receiver calculates a traversal time based on the difference between the arrival time of the fragment and this time stamp, and sets the reassembly timer based on this traversal time. A receiver can independently set the reassembly timer to a first reassembly time set by the user for fast networks or to a second reassembly timer set by the user for slow networks based on whether the receiver and sender are on the same subnet. |

Method of connecting a new device to existing network
In a centralized radio network consisting of several devices one device acts as master or network coordinator and has a transmission range. Basically, other devices of the network are able to adopt the role of a coordinator. This ability is used to enlarge the area of the network to a size larger than the transmission range of the master. A device asks its parent PNC to become a child PNC when a newly turned on device acts as a temporary PNC and broadcasts an initiation beacon indicating that it looks for a child PNC. The child PNC reports that it is available. The new device determines one of the available child PNCs to be its new master. The acknowledgment for the selected child PNC may be broadcasted to inform all the devices in the transmission range of the new device. The new device quits the role of the temporary PNC and associates to the existing network. |

Method and apparatus for application driven adaptive duplexing of digital subscriber loops
To improve the performance of DSL modems, a DSL duplexing ratio for a new communication is selected according to the communications needs of an application. A required upstream and downstream bit rate for application communications is determined. From the ratio of these bit rates, a desired duplexing ratio is calculated. The operation of the modem is then adapted to choose a duplexing ratio that approximates the desired duplexing ratio for the application. To optimize modem operation, the size and position of the upstream and downstream bandwidths used for transmission are intelligently selected when the bit rate necessary for making the transmission is less than the total available bandwidth provided by the chosen duplexing ratio. By intelligently selecting a minimum number of subcarriers for Digital Multi-tone (DMT) signal transmission, a reduction in line driver power consumption is effectuated. Additionally, by intelligently selecting the position of the used bandwidth within the total available bandwidth, near-end crosstalk (NEXT) noise may be minimized. |

Display and method of manufacturing the same
In a light transmitting, color image display unit, a top surface of a black matrix partition wall exhibits lyophobicity relative to in-solution pigment particles while sidewall surfaces of the black matrix exhibit lyophilicity relative to in-solution pigment particles. This allows the pigment containing solutions to abut without repulsion against the sidewall surfaces. Consequently, it is possible to prevent color filter solutions deposited through an inkjet deposition process from overflowing over the lyophobic partition wall tops into adjacent pixel regions and it is also possible to conformably define color filters of consistent thickness between the black matrix partition walls. |
