| 20100005328 | Integrated Circuit with Modular Dynamic Power Optimization Architecture - A system and method for regulating power consumption within an integrated circuit (IC) with a modular design. The IC is designed so that any one distinct functional module within the IC utilizes only transistors with a substantially same or similar critical voltage level, which may for example be the threshold voltage of the transistors. Consequently, the supply voltage delivered to each functional modules can be lowered to the minimum voltage necessary to enable the transistors within the module to operate. Similarly, modules within the IC may be designed with transistors which share a common value for a substrate bias voltage or a clock speed, or with a combination of common values for several electrical factors. In this way, it is possible to reduce power consumption by fine-tuning the voltages supplied to (or clock speeds driving) specific modules, in a way which is custom-tuned to each module. | 01-07-2010 |

| 20090274376 | METHOD FOR EFFICIENTLY BUILDING COMPACT MODELS FOR LARGE MULTI-CLASS TEXT CLASSIFICATION - A method of classifying documents includes: specifying multiple documents and classes, wherein each document includes a plurality of features and each document corresponds to one of the classes; determining reduced document vectors for the classes from the documents, wherein the reduced document vectors include features that satisfy threshold conditions corresponding to the classes; determining reduced weight vectors for relating the documents to the classes by comparing combinations of the reduced weight vectors and the reduced document vectors and separating the corresponding classes; and saving one or more values for the reduced weight vectors and the classes. Specific embodiments are directed to formulations for determining the reduced weight vectors including one-versus-rest classifiers, maximum entropy classifiers, and direct multiclass Support Vector Machines. | 11-05-2009 |

| 20100050571 | Method And Apparatus For Inflating And Sealing Packing Cushions With Rotary Sealing Mechanism - An apparatus for inflating and sealing packing cushions has a drive mechanism for feeding a preconfigured film material to a sealing mechanism in a flattened state without wrinkles in the sealing region in which a longitudinal seal is formed. In one aspect, the drive mechanism comprises a pair of upper adjacent belts and a backing element, such as a lower belt. The sealing mechanism may be a rotary sealing wheel that contacts the film material between the upper adjacent belts. | 03-04-2010 |
