| 20110173178 | METHOD AND SYSTEM FOR OBTAINING SCRIPT RELATED INFORMATION FOR WEBSITE CRAWLING - A web crawler system has an automatic website crawler and a virtual browser that provides script related information to the website crawler. The virtual browser transforms an HTML document included in a web page of the website into an XML document, and builds a document object model containing document objects in a tree structure based on the XML document. The virtual browser extracts from the DOM scripts that are potentially executable, and executes the extracted scripts using a browser object model provided for the virtual browser containing objects and methods and properties that are used for script execution so as to capture script related information generated by execution of the scripts. | 07-14-2011 |

| 20080294670 | METHOD AND SYSTEM FOR HIERARCHICAL LOGGING - A method and system to create a logical hierarchy of log files is described. The method records data about each event occurring during a maintenance procedure in a first order log file. Detailed information about the event is redirected to a further order log file. In some case, the hierarchical nature allows the event data to be analyzed and the error causing the event to be corrected without human intervention. | 11-27-2008 |
| 20100153942 | METHOD AND A SYSTEM FOR DELIVERING LATEST HOTFIXES WITH A SUPPORT PACKAGE STACK - A method and a system are described that involve delivering latest hotfixes with a support package stack. In one embodiment, the method includes receiving a selection of a stack of update components, the stack to be applied on a product and receiving correction data for an update component of the stack, the correction data being available on a software provider system. The method also includes detecting the correction data for the update component. Further, the method includes applying the correction data on the update component in the stack. | 06-17-2010 |

| 20100145692 | METHODS AND ARRANGEMENTS IN A TELECOMMUNICATIONS NETWORK - The present invention relates to a postfilter and a postfilter control to be associated with a postfilter for improving perceived quality of speech reconstructed at a speech decoder. The postfilter control comprises means for measuring stationarity of a speech signal reconstructed at a decoder, means for determining a coefficient to a postfilter control parameter based on the measured stationarity, and means for transmitting the determined coefficient to a postfilter, such that the postfilter can process the reconstructed speech signal by applying the determined coefficient to the postfilter control parameter to obtain an enhanced speech signal. | 06-10-2010 |
| 20110119039 | Objective Measurement of Audio Quality - In an apparatus for objective perceptual evaluation of speech quality, parameters BandwidthRef and BandwidthTest representing the bandwidth are forwarded to a calculator | 05-19-2011 |
| 20110153336 | MULTI-MODE SCHEME FOR IMPROVED CODING OF AUDIO - The present invention relates to an improved scheme for coding of audio. In particular, the present invention relates to an encoder device and a method for coding an input signal in an encoder system. The method comprises applying a first mode to the input signal to form a first output and applying a second mode to the input signal to form a second output. A first processed output is then formed from at least a part of the first output, and a second processed output is formed from at least a part of the second output. Forming a second processed output comprises estimating a part of the input signal from at least a part of the second output. Then, an optimum mode is determined based on the firstprocessedoutput and the secondprocessedoutput, and the output according to the optimum mode is selected. | 06-23-2011 |

| 20090018825 | LOW-COMPLEXITY, NON-INTRUSIVE SPEECH QUALITY ASSESSMENT - A non-intrusive signal quality assessment apparatus includes a feature vector calculator that determines parameters representing frames of a signal and extracts a collection of per-frame feature vectors (φ;(n)) representing structural information of the signal from the parameters. A frame selector preferably selects only frames (Ω\with a feature vector (φ;(n)) lying within a predetermined multi-dimensional window (⊖). Means determine a global feature set (ψ) over the collection of feature vectors (φ;(n)) from statistical moments of selected feature vector components ((1̂,01, . . . O11). A quality predictor predicts a signal quality measure (Qj from the global feature set (ψ)). | 01-15-2009 |
