| 20090271182 | COMPUTER-IMPLEMENTED METHODS AND SYSTEMS FOR MODELING AND RECOGNITION OF SPEECH - In accordance with the present invention, computer implemented methods and systems are provided for representing and modeling the temporal structure of audio signals. In response to receiving a signal, a time-to-frequency domain transformation on at least a portion of the received signal to generate a frequency domain representation is performed. The time-to-frequency domain transformation converts the signal from a time domain representation to the frequency domain representation. A frequency domain linear prediction (FDLP) is performed on the frequency domain representation to estimate a temporal envelope of the frequency domain representation. Based on the temporal envelope, one or more speech features are generated. | 10-29-2009 |

| 20100318519 | Incremental Maintenance of Inverted Indexes for Approximate String Matching - In embodiments of the disclosed technology, indexes, such as inverted indexes, are updated only as necessary to guarantee answer precision within predefined thresholds which are determined with little cost in comparison to the updates of the indexes themselves. With the present technology, a batch of daily updates can be processed in a matter of minutes, rather than a few hours for rebuilding an index, and a query may be answered with assurances that the results are accurate or within a threshold of accuracy. | 12-16-2010 |

| 20090171944 | Set Similarity selection queries at interactive speeds - The similarity between a query set comprising query set tokens and a database set comprising database set tokens is determined by a similarity score. The database sets belong to a data collection set, which contains all database sets from which information may be retrieved. If the similarity score is greater than or equal to a user-defined threshold, the database set has information relevant to the query set. The similarity score is calculated with an inverse document frequency method (IDF) similarity measure independent of term frequency. The document frequency is based at least in part on the number of database sets in the data collection set and the number of database sets which contain at least one query set token. The length of the query set and the length of the database set are normalized. | 07-02-2009 |
| 20100125559 | SELECTIVITY ESTIMATION OF SET SIMILARITY SELECTION QUERIES - The invention relates to a system and/or methodology for selectivity estimation of set similarity queries. More specifically, the invention relates to a selectivity estimation technique employing hashed sampling. The invention providing for samples constructed a priori that can efficiently and quickly provide accurate estimates for arbitrary queries, and can be updated efficiently as well. | 05-20-2010 |
| 20100132036 | VERIFICATION OF OUTSOURCED DATA STREAMS - Embodiments disclosed herein are directed to verifying query results of an untrusted server. A data owner outsources a data stream to the untrusted server, which is configured to respond to a query from a client with the query result, which is returned to the client. The data owner can maintain a vector associated with query results returned by the server and can generate a verification synopsis using the vector and a seed. The verification synopsis includes a polynomial, where coefficients of the polynomial are determined based on the seed. The data owner outputs the verification synopsis and the seed to a client for verification of the query results. | 05-27-2010 |

| 20100298706 | RESPIRATORY-GATED THERAPY ASSESSMENT WITH ULTRASONIC CONTRAST AGENTS - An ultrasonic imaging apparatus and method are described for monitoring the progress of therapy for pathology such as lesions, tumors, and metastases by means of contrast agent imaging. A sequence of images are acquired as a bolus of contrast agent infuses the tissue containing the pathology. A contrast wash-in time parameter is calculated for both the tumor and normal tissue, and a ratio is calculated of the two wash-in time parameters (called WITR) which removes the effects of variations in the procedure from one therapy monitoring session to another. A difference curve of the time-intensity curves of the pathology and normal tissue is also produced, which is similarly immune to procedural variations. The motional effects of respiration can be taken into account by detecting the position of a landmark such as the diaphragm in each of the images of the sequence and discarding from processing those which exhibit a change in the position of the landmark relative to the probe. | 11-25-2010 |

| 20110219447 | Identification of Unauthorized Code Running in an Operating System's Kernel - Computer implemented methods, system and apparatus for managing execution of a running-page in a virtual machine include associating an execution trace code with the running page by a security virtual machine. The execution trace code generates a notification upon initiation of the execution of the running page by the virtual machine. The notification is received by the security virtual machine running independent of the virtual machine executing the running-page. The running page associated with the execution trace code is validated by the security virtual machine as authorized for execution. An exception is generated if the running-page is not authorized for execution. The generated exception is to prevent the execution of the running page in the virtual machine. | 09-08-2011 |

| 20100014718 | Computationally Efficient Feature Extraction and Matching Iris Recognition - A method and system for uniquely identifying a subject based on an iris image. After obtaining the iris image, the method produces a filtered iris image by applying filters to the iris image to enhance discriminative features of the iris image. The method analyzes an intensity value for pixels in the filtered iris image to produce an iris code that uniquely identifies the subject. The method also creates a segmented iris image by detecting an inner and outer boundary for an iris region in the iris image, and remapping pixels in the iris region, represented in a Cartesian coordinate system, to pixels in the segmented iris image, represented in a log-polar coordinate system, by employing a logarithm representation process. The method also creates a one-dimensional iris string from the iris image by unfolding the iris region by employing a spiral sampling method to obtain sample pixels in the iris region, wherein the sample pixels are the one-dimensional iris string. | 01-21-2010 |
