  • Publication number: 20210297001
    Abstract: A modular power converter with wide-bandgap semiconductors, in particular SiC semiconductors. The modular power converter has at least two base units. The base units are connected together on the input side, and each base unit has an input circuit on the input side and an output circuit on the output side. The input circuit and the output circuit are each formed by the wide-bandgap semiconductors arranged in a B6-bridge circuit. An intermediate circuit capacitor is connected in parallel with the input circuit and the output circuit forming an intermediate circuit. The input circuits of the base units or a sub-quantity of the base units are arranged in a series circuit. At least one inductor is arranged between each pair of input circuits.

  • Patent number: 10166124
    Abstract: In order to control at least one adjustable actuator of a connection apparatus to an orthopedic device with tower limbs, actual values of at least two movement parameters of the orthopedic device are continuously acquired by at least two sensors. A functional relationship is established between the sequences of actual values of the at least two movement parameters. This functional relationship is continuously repeatedly compared to functional relationships in the case of defined movement patterns in order to select in each case the movement pattern which fits best to the acquired actual values. Then control signals for the actuator are generated using a sequence of intended values defined for the best-fitting movement pattern.

  • Publication number: 20150190250
    Abstract: In order to control at least one adjustable actuator of a connection apparatus to an orthopaedic device with lower limbs, actual values of at least two movement parameters of the orthopaedic device are continuously acquired by at least two sensors. A functional relationship is established between the sequences of actual values of the at least two movement parameters. This functional relationship is continuously repeatedly compared to functional relationships in the case of defined movement patterns in order to select in each case the movement pattern which fits best to the acquired actual values. Then control signals for the actuator are generated using a sequence of intended values defined for the best-fitting movement pattern.

  • Patent number: 8972332
    Abstract: A server system stores web analytics data for a web page in a device. The web analytics data comprises a plurality of prior time-value pairs, each pair including a value of an attribute associated with the web page and a time associated with the value. For a particular attribute, the server system collects a new time-value pair including a new value associated with the web page and a new time indicating when the value was determined. The server system estimates a predicted value for the attribute and an associated error-variance at the new time by applying a forecasting model to the prior time-value pairs in respective subsets of the web analytics data. The collected new time-value pair is tagged if its value is outside the error variance of the predicted value for the particular attribute.

  • Patent number: 8924303
    Abstract: The embodiments disclosed herein include new, more efficient ways to request, create, send, and receive product reviews from the Internet. One aspect of the invention is an email message for a customer. The email message includes a request to review a product obtained by the customer in a transaction; a rating input area and/or a text input area; an authentication token that includes a transaction identifier corresponding to the transaction; and an HTTP form submission command to send a response to the request from the customer to a remote computer. The response includes a rating entered in the rating input area and/or text entered in the text input area, and the authentication token.

  • Patent number: 8682816
    Abstract: A server system stores time series data for a data source. The time series data comprises a plurality of time-value pairs, each pair including a value associated with an attribute of the data source and a time. For a particular attribute, the server system generates a plurality of forecasting models for characterizing the time-value pairs, each model including an estimated attribute value and an associated error-variance. For a time-value pair, the server system determines a plurality of differences between the value of the time-value pair and respective estimated attribute values of the plurality of forecasting models and tags the time-value pair as an anomaly if the differences for at least a first subset of the forecasting models are greater than the corresponding error variances. In response to a request from a client application, the server system returns at least a subset of the time-value pairs tagged as anomalies.

  • Publication number: 20130144862
    Abstract: Systems and methods for clustering user reviews are disclosed in which a plurality of user reviews are extracted from electronic documents. The electronic documents contain user reviews of a plurality of items of interest. A set of user reviews is identified in the plurality of user reviews as being associated with the same item of interest in the plurality of items of interest. Item identifying information included in the electronic documents is used for this identification. The set of user reviews is then associated with the same item of interest. Examples of item identifying information include unique product identifiers, brand names, model numbers, and category information. In some instances, the item identifying information is extracted from metadata included in the electronic document. In some instances, the electronic documents are obtained from e-commerce websites or product-review websites.

  • Patent number: 8239392
    Abstract: Methods, systems and apparatus, including computer program products, for enhancing query performance through fixed length hashing of multidimensional data. According to one method, a fixed length hash of a multidimensional data record is created where the hash has respective fixed length sections for each data dimension of the record being hashed. The composite fixed length hash is stored with a reference to the original data record to which it corresponds. Query parameters are hashed and compared to a corresponding section of the fixed length hash to determine a set of candidate records.
